第九章、QtDesigner可视化设计界面布局组件介绍

第九章、QtDesigner可视化设计界面布局组件介绍

第九章、QtDesigner可视化设计界⾯布局组件介绍
⼀、引⾔
在Qt Designer中,在左边部件栏的提供了界⾯布局相关部件,如图:
可以看到共包含有四种布局部件,分别是垂直布局(Vertical Layout)、⽔平布局(Horizontal Layout)、⽹格布局(Grid Layout)、表单布局(Form Layout),实际上除了以上布局之外,还有两种布局,⼀种是没有布局的布局,称为绝对布局,⼀种是多种布局组合或嵌套使⽤,称为组合布局。

⼆、布局概述
在Designer设计的GUI界⾯中,如果使⽤绝对布局,则窗⼝中的部件在窗⼝拉伸或缩放时⼤⼩和位置都不会改变,这对于窗⼝要进⾏拉伸以及应⽤适应屏幕分辨率变化导致的被动窗⼝⼤⼩调整的情况,界⾯就不是设计者需要的展⽰效果,为此需要进⾏布局管理,确保窗体拉伸时整体界⾯保持正常显⽰。

Designer中提供了四种布局,分别是垂直布局(Vertical Layout)、⽔平布局(Horizontal Layout)、⽹格布局。

在Eclipse中使用SWT进行界面设计

在Eclipse中使用SWT进行界面设计

在Eclipse中使用SWT进行界面设计1. 为什么要使用SWT?SWT是一个IBM开发的跨平台GUI开发工具包。

至于为什么IBM要费劲自己另起炉灶开发一个GUI工具包,而不是使用Sun现有的由AWT, Swing, Java 2D, Java 3D等构成的Java GUI框架,那就说来话长了。

(记得在一个BBS上读过一个关于SWT起源的调侃类的帖子)。

在SWT之前,Sun已经提供了一个跨平台GUI开发工具包AWT (Abstract Windowing Toolkit)。

虽然AWT框架也使用的是原生窗口部件(native widgets),但是它一直未能突破LCD问题。

LCD问题导致了一些主要平台特征的遗失。

如果你不明白的话(其实我也没明白),换句话说,如果平台A有窗口部件(widgets)1–40,而平台B有窗口部件(widgets)20–25,那么跨平台的AWT框架只能提供这两个窗口部件集的交集。

为解决这个问题,Sun又创建了一个新的框架。

这个框架不再使用原生窗口部件,而是使用仿真窗口部件(emulated widgets)。

这个方法虽然解决了LCD问题,并且提供了丰富的窗口部件集,但是它也带来了新的问题。

例如,Swing应用程序的界面外观不再和原生应用程序的外观相似。

虽然在JVM中这些Swing应用程序已经得到了最大程度的性能改善,但是它们还是存在着其原生对应物所不具有的性能问题。

并且,Swing应用程序消耗太多的内存,这样Swing不适于一些小设备,如PDA和移动电话等。

IBM进行了尝试以彻底解决AWT和Swing框架带来的上述问题。

最终,IBM创建了一个新的GUI库,这就是SWT。

SWT框架通过JNI 来访问原生窗口部件。

如果在宿主(host)平台上无法找到一个窗口部件,SWT就会自动地模拟它。

2. SWT应用程序的组成一个SWT应用程序的基本组成部分为显示界面(Display)、命令界面(Shell,使命令进入并使运行初始化)和窗口部件(Widgets)。

The GUI Builder that we will look at in this tutorial is the Designer created by Instantiations, Inc., and is available at . We will be using version 2.0.0 of the Designer in this tutorial.A GUI Builder:In the previous tutorials, we have seen that SWT and Eclipse are fairly simple and straightforward to use. One of the most common questions about SWT, however, is “Where is the GUI Builder?” The answer is that there is no GUI Builder that comes with Eclipse. However, because Eclipse is open source and designed for plug-ins, a GUI Builder plug-in is able to be made and can be integrated right into Eclipse.The Designer is a plug-in that allows you design SWT and Swing GUIs in Eclipse. The Designer is available at . A restricted version of the plug-in is available for free download at the above website. There is also a professional version, which includes extra features, that is available for $199 USD. Look at /swt-designer/comparison.html to see a comparison between the free and the professional versions.As of version 2.0 of the Designer, Instantiations includes both SWT and Swing support in the Designer. The SWT part is the same as in previous versions and is called the SWT Designer. The Swing part is called the Swing Designer and is similar to the SWT Designer. There is also a WindowBuilder product in the Designer which is simply both the SWT Designer and the Swing Designer.Since most of the features are the same or similar between the SWT Designer and the Swing Designer, this tutorial will mainly look at features of the SWT Designer. To demonstrate the similarities and the differences between the SWT Designer and the Swing Designer, one of the examples at the end of this tutorial will be done in Swing.1 This work was funded by an IBM Eclipse Innovation Grant.2 © Raphael Enns, Shantha Ramachandran and David ScuseAcquiring the Designer Plug-in:You can download the Designer from the website, . It can be found in the Download section. Make sure you get the correct file for your version of Eclipse. In order to download the Designer, you must have a username and password. You can get a username and password by registering at the Designer’s website.Installation:Once you have downloaded the Designer, installing it is quite simple. First make sure Eclipse is closed. Move the zip file into your Eclipse directory and then unzip the file. It will add three folders to your plugin directory that start with com.swtdesigner.To make sure that the plug-in was successfully installed, start Eclipse. Go to the menu item Help > About Eclipse Platform. Click on the Plug-in Details button, and a list will appear. The Designer and the SWT-Designer Help Plug-in items should appear in the plug-in list.In the case that you would wish to remove the Designer from your computer, the Designer creates a batch file called designer-delete.bat in your Eclipse program directory. Run this file to remove the Designer.Activating the Designer:Before you begin using the Designer you have to activate it. To start the activation process, select Window > Preferences inside Eclipse. Select the “+” beside “Designer” on the left side of the Preferences window, click on License, and then click on the button that says “Registration and Activation”.Both SWT and Swing support comes with the Designer product, but depending on your serial number, only one of the three products is activated. For example, if you have a valid serial number for the SWT Designer, you can use the SWT functionality of the Designer, but you will not be able to use the Swing functionality except in evaluation or free mode. If you have a serial number for WindowBuilder, you will have full use of both the SWT and Swing functionality of the Designer.Select the type of Designer that you want to activate, select the desired mode, and then click Next. Follow the directions in the following pages to activate the Designer. Once it has been activated you are ready to start designing GUIs.Creating a new SWT/JFace Java Project:An SWT/JFace Java Project and a regular Java Project are nearly equivalent. They both create a Java project and you can use the Designer with both types. The only difference between an SWT/JFace Java project and a regular Java project is that the SWT/JFace Java project will automatically add the SWT and JFace jar files to the build path.To create an SWT/JFace Java Project, select File > New > Project, and then in the resulting window select SWT > SWT/JFace Java Project.Click Next and then create the project the way you would normally create a Java Project. You do not have to add the SWT and JFace jar files to the build path because they are added automatically.Note: To be able to use SWT, the SWT runtime DLL must be accessible by the SWT jar file. For information on how to do this, see the Installing Eclipse tutorial, which can be found at http://www.cs.umanitoba.ca/~eclipse.Creating a new SWT Java File:The easiest way to set up a file to use the Designer is to use the Designer Wizard. Select File > New > Other from the menu and select Designer > SWT Application.Click Next. In the window that opens, choose the project the file will go in and give the file a name. You can also select which method the SWT code will initially appear in by selecting the appropriate radio button as shown below. Click Finish to create the new file.This will add a file to your project that already has an SWT event loop and a shell created for you. The file should automatically open in the Designer Editor.To open a file that has not been created by the Designer, simply right-click on the file and select Open With > Designer Editor.This will open the file in the Designer Editor in the source view. There are two tabs at the bottom of the editor window labeled Source and Design as shown below. If you click on the Design tab, the file will be displayed in the design view and you will be able to visually design your GUI.Two other quick ways to switch between the source and design view are to click on the “Switch between source and designer” button in the toolbar that is shown below, or simply press F12.Note: If a file was last opened in the Designer Editor, it will continue to open in that editor until a different editor is selected to open the file with.Below is an image of the Designer in the design view for a new file that was created using the SWT Application wizard. Initially the class only has a shell with no controls and no layout.Note: To view the Designer Editor using the full screen, simply double click on the tab of the current file at the top of the editor window.Note: The above image is of the professional version of the SWT Designer. The free version looks identical with a few less controls in the Control Palette and a few less items in the editor’s toolbar.Parts of the Designer:There are five different parts in the Designer design view: the Method List, the Control Tree, the Control Palette, the Content Pane, and the Inspector.The Method List is a dropdown list of all the methods where controls are created. In this example, the controls are created in the method “open”. When a method is selected, its controls appear in the Content Pane.The Control Tree shows the hierarchy of controls in the selected method. You can select a control by clicking on it.The Control Palette is the palette from which to choose your controls. It contains all the controls that can be added to your GUI with the Designer. Below is shown the Control Palette for the free version on the left and the professional version on the right.The Content Pane shows the GUI design as it will look when your application is run. It will also display some extra features to help in editing the design. There is a toolbar at the top of the Content Pane which has buttons for test, cut, copy, paste, delete, as well as several buttons to help position controls. The positioning buttons will only work with controls on a NullLayout. Some of the positioning buttons are only available in the professional version.The Inspector shows all of the properties and events of a selected control and allows you to modify them without going into the code.Select a property by either clicking on the property title or the property value. A property editor is then displayed which allows you to change its value. While editing a property value, you can press Enter to apply the value or press Esc to return to the previous value. If a property’s value is not the default value, the property title changes color. Expand or collapse complex properties such as style by clicking on the ‘+’ or ‘-’ beside the property title.Some properties are selected through a selection property editor. Simply select the value from the list that appears after clicking on the down arrow as shown below.The layout of the Designer’s editor can be changed in the Designer’s preferences. Select Preferences from the Window menu to open the Preferences window. Expand the Designer item and select Editor Layout. The Editor Layout property page is shown below.You can choose one of three options in the Editor layout dropdown list. The “On separate notebooks tabs” option is the default option which places the design view and the source view on separate pages. The “Above each other with a split pane” option will remove the Source and Design tabs and place the design view above the source view in the same editor. The “Side by side with a split pane” option is similar except it places the design view on the left and the source view on the right. This allows you to view the source while designing in the design view without having to switch back and forth between the design and source views. Since the Designer updates the GUI bidirectionally, making changes in either the design or source view will instantly update the other view.There are four pictures in the Canvas position group, each with a radio button next to it. These options place the Control Tree and the Inspector in different positions in the editor. You can see where each part is by looking at the pictures. The default option is the top-left option where the Control Tree and the Inspector are at the far left of the editor.Open Definition and Convert Local to Field ButtonsThere are two small buttons between the Inspector and the Control Tree. These are“Open Definition” and “Convert Local to Field” (or “Convert Field to Local”if it has already been clicked once).When a control is selected and the “Open definition” button is pressed, the Designer will switch to the source view and place the cursor on the line where the selected control is instantiated.By default, the Designer generates code using the block style: a control is declared and instantiated inside its own block of code. When a control is declared inside its block of code, it is visible only to its children and itself.When a control is selected and the “Convert local to field” button is pressed, the Designer will move the declaration of the control from inside its block of code to being a field in the GUI class. When a control is declared as a field, it is visible to everything in that class. If there is a conflict of names when converting a control to a field, the Designer will give the control a unique name.After the “Convert local to field” button is pressed once it becomes the “Convert local to field” button. When the button is pressed now, the Designer will move the declaration of the control back inside its block of code.In the examples as the end of this tutorial we will see in more detail how these buttons work.Note: An alternative to the block style of coding is the flat style. Controls are not declared in their own blocks, but are rather declared in the same scope. This is often how a GUI is coded when done by hand. The Designer supports generating code in this style. We will look at how to make the Designer generate code in this style in the Code Generation section of this tutorial.Handling Events with the Designer:Events occur when the user interacts with the UI. The appropriate event-handling code is then executed. In order to know when events occur, event listeners must first be added to your controls. The Designer makes it very easy to add and remove event listeners to your controls.Adding an Event Listener with the SWT Designer:There are two ways to add an event listener with the SWT Designer. The first way is through the Inspector. First select a control in either the Control Tree or the Content Pane. Expand the “events” complex property in the Inspector. Then expand an event and double-click or press Enter on the method you wish to implement.The second way to add an event listener is to simply right-click on a control (either in the Content Pane or in the Control Tree), select Implement > [name of the event] > [name of the method to implement].A quick way to add event listeners to buttons (including check and radio buttons) and menu items (professional version only) is to simply double-click on the button or menu item. When double-clicked, a selection event listener will be created.Any way you add an event, the SWT Designer will automatically create an event listener for the selected event method. The SWT Designer will then switch to the source view and go directly to the new event handler method. The code generated looks like the following:{final Label label = new Label(shell, SWT.NONE);label.addMouseListener(new MouseAdapter() {public void mouseDoubleClick(MouseEvent e) {}});label.setText("label");}There are two ways to quickly return to the event-handling code from the design view. In the Inspector, expand “events” and then the event. Then double-click or press Enter on the event method to return to the code. The events’ property value in the Inspector is a list of all the events implemented, and each individual event’s property value is the list of methods implemented. If a method has been implemented, its property value is the line number in the source code where its event-handling code begins.The other way to quickly return to the event-handling code is to right-click on a control (either in the Content Pane or in the Control Tree), and then select the menu item for the correct method that was implemented. Shown below is “mouse.doubleClick > 32” being selected. In this example, “mouse” is the event, “doubleClick” is the event method, and “32” is the line number in the source code on which the method begins.Note: The professional version of the Designer is able to generate an event handler stub method when a new event is created. We will look at how to make the Designer generate this method in the Code Generation section of this tutorial.Deleting an Event Listener with the SWT Designer:There is only one way to delete an existing event handler in the SWT Designer. Select a control in either the Content pane or in the Control Tree. In the Inspector expand “events” and then expand the event. Click on the event method you wish to delete and then press Delete. If there are no other methods that have been implemented for that event, the SWT Designer will also delete the event listener for that event.Using Layout Managers in the SWT Designer:The first step to creating an application is to choose a layout. You can use either the default NullLayout or you can choose one of the layouts listed under the Layouts tab in the Control Palette. FillLayout, RowLayout, and GridLayout are all supported in the free version of the SWT Designer. In addition to the layouts in the free version, the professional version also supports FormLayout, StackLayout, BorderLayout, FlowLayout, and AWT GridLayout. BorderLayout, FlowLayout, and AWT GridLayout are ports of AWT layouts. Below are shown the Layout tabs in the free version (left) and the professional version (right).By default, the SWT Designer does not support designing a GUI using the NullLayout. If no layout is selected for a container, the container in the Content Pane will have red text in the center saying “Please choose a layout manager.” We will find out how to get rid of this message and how to enable support for the NullLayout in the SWT Designer in the NullLayout section of this tutorial.After you select one of the layouts from the Control Palette, place your mouse over a container in the Content Pane. The area where the layout can be applied will appear highlighted, as shown below. Click the mouse and the layout will be applied. You can check and make sure it was applied by looking at the Inspector. The value of the layout property should now say the name of the layout selected (it will be blank if the NullLayout is used).To remove a layout from a container, select the container in either the Content Pane or in the Control Tree, click on the layout property in the Inspector, and then press Delete. Another way to remove a layout is to right-click on the container holding the layout in either the Content Pane or Control Tree and select Delete Layout.When a layout is removed from a container, the SWT Designer converts the layout to an equivalent NullLayout by using the setBounds() method call for each control in the container. This means that after you delete a layout, the controls will be in the same position and the same size as before, even though the layout is now the NullLayout.To switch from one layout to another on a container that already has one or more controls on it, you must first delete the current layout and then apply the new layout. If the container has no controls on it, you are able to change layouts without deleting the current layout first, unless the current layout is a FormLayout or a BorderLayout. Adding controls to a container is similar to placing a layout. Simply select the desired control in the Control Palette, move your mouse to the desired area in the Content Pane, and click to place the control. A control can also be added by placing the control on the Control Tree. To delete a control, simply select it and press Delete. More specific examples of how to place controls for each layout are shown in the individual layout sections.For more information on SWT layout managers, see the tutorial Eclipse Layouts. NullLayout:In order to begin designing applications using the NullLayout, you must first enable it in the SWT Designer. To do this, go to the menu item Window > Preferences. On the left side of the Preferences window, expand Designer and click on SWT. On the right side, check “Allow absolute/null layout (setBounds())”. Then click OK.The NullLayout is very easy to use. You simply have to place and size a control exactly as you want it. One downfall with using the NullLayout is that you may lose some portability. Though your application may display correctly on your platform and screen resolution, on another platform, or on a different screen resolution, it may not display correctly.The NullLayout has no layout properties to set. To place a control on a shell with a NullLayout, select a control from the Control Palette, click on the shell to set the top-left corner of the control, and then drag to set the size of the control. The new control will then be placed on the area of the shell that you selected. To move a control, simply click on the control and drag it to where you want it. To resize a control, select the control either in the Content Pane or in the Control Tree. Then click and drag the handles that are around the edges of the control. To delete a control, simply select the control and press Delete.When you create, move, or resize a control that is on a NullLayout, a grid is shown. The edges of the control you are creating, moving, or resizing will always snap to the grid points. The grid helps you to place the controls evenly. A button being moved on a NullLayout is shown below.You are able to change the distance between the points on the grid. To do this, select Preferences from the Window menu. Expand the Designer item and select the General item. Setting the Grid step value will set the distance between the points. You can enter a value between 1 and 100. This value is the number of pixels between points. The default Grid step value is 5.There are several buttons on the toolbar above the Content Pane that can be used to align controls on a NullLayout. Most of the buttons are only available in the professional version of the Designer. Only the two buttons on the far right are also available in the free version.The buttons on the far right are “Center horizontally in window” and “Center vertically in window”. To use them, select a control on a NullLayout and press one of the buttons. The selected control is now centered in the container.To enable the other buttons, multiple controls must be selected. When multiple controls are selected and one of the alignment buttons is pressed, the controls will line up their edges or centers, depending on which button is pressed, to one of the selected controls. Generally the selected controls will always be aligned to the selected control highest in the z-order. The only way to align controls to a specific control regardless of its location in the z-order is to select the control you wish to align to, hold down Ctrl or Shift, and then in the Content Pane select the controls you wish to align. If you then press one of the alignment buttons, the other controls will align themselves to the first control selected. Once an alignment button has been pressed, any subsequent presses to any alignment button will return to aligning the selected controls to the control highest in the z-order.Below is shown a shell with a NullLayout which has several controls placed in it:Note: You cannot change the size and position of a control in the Inspector using NullLayout. To do this you must go into the source code and modify the setBounds() method call or move and resize the control on the Content Pane.Note: If there is any container which uses a layout other than a NullLayout, and that container’s parent uses the NullLayout, it will display controls as if it had a NullLayout. That means that every control still needs a setBounds() call even though the container it is on does not use the NullLayout. This makes using a different layout manager on the container to be useless. This is why you should either use the NullLayout for everything in an application, or do not use it at all.FillLayout:FillLayout is the easiest layout manager to use, both with and without the SWT Designer. It places your controls in either a single row or single column. FillLayout has only one style property to set – dir, which can be horizontal or vertical. There are two ways to set this style. The first is through the Inspector. Select the container in the Control Tree and then expand the layout property and the style property. The property value of the dir property can be set to either horizontal or vertical.The second way to set this is within the Content Pane. When a control in a container with FillLayout is selected, a small switch appears in the top right corner of the container indicating which direction the layout is in. Clicking on this switch changes the direction. In the example below, the switch is indicating a horizontal FillLayout, as there are two “controls” side-by-side, horizontally.For a vertical FillLayout, two “controls” are pictured one on top of the other, vertically. To add the first control to a container using FillLayout, select a control from the Control Palette and click anywhere in the container. To add more controls, select a control from the Control Palette, and then place the cursor to the left or right of a control already placed (if the dir property is horizontal), or to the top or bottom of a control (if the dir property is vertical). A small red line will appear where the control is to be placed, as shown below.If no red line appears when trying to place a control, make sure that the container that the control will be placed in is selected in the Control Tree. To move a control, simply click and drag the control to the desired position.RowLayout:Using RowLayout is similar to FillLayout in that you can set a dir property to horizontal or vertical. However, RowLayout does have a few more properties that can be set. These can all be set using the Inspector.If the justify property is set to true, the controls will be evenly spaced out across the screen either horizontally or vertically depending on the dir property. The margin properties set how many pixels away from the edges of the container to place to controls. When pack is true, all the controls are their natural size. When pack is false, all the controls are the same size. The spacing property sets how many pixels are to be between each control. When wrap is true, the controls are wrapped onto the next line if they cannot fit all on one line.When placing a control onto the container, a red line will appear where the control will be placed. By moving your mouse around, you can specify exactly where in the layout you wish to place another control.When a control placed on a container using RowLayout is selected, it will have three small square handles. The handles are on the bottom edge, right edge, and bottom-right corner, as shown below. If you click and drag these handles, you can resize individual controls.。

上面已讲述,这里不多谈。

下面讲一个操作实例:在窗体中加入组件加入2 个标签组件(Label)、2 个文本框组件(Text)和2 个按钮组件(Button),如图4所示。

if(text.getText()!=""|text_1.getText()!="")//调用JFace的信息对话框显示登录信息MessageDialog.openInformation(shell,"登录信息","欢迎"+text.getText()+"进入系统!"); else//调用JFace的错误对话框显示出错信息MessageDialog.openError(shell,"错误","用户名或密码为空,请重新输入!");由于用到了JFace的对话框,在程序的前面要引入相应的包:import org.Eclipse.jface.dialogs.*;输入密码时要在密码框显示“*”,需要添加SWT.PASSWORD选项:final Text text_1=new Text(shell,SWT.BORDER|SWT.PASSWORD);import org.Eclipse.swt.SWT;import org.eclipse.swt.events.SelectionAdapter; import org.eclipse.swt.events.SelectionEvent; import org.eclipse.swt.widgets.Button;import org.eclipse.swt.widgets.Display;import bel;import org.eclipse.swt.widgets.Shell;import org.eclipse.swt.widgets.Text;import org.eclipse.jface.dialogs.*;public class login {private Text text_1;private Text text;protected Shell shell;/** *//*** Launch the application* @param args*/public static void main(String[] args) {try {login window = new login();window.open();} catch (Exception e) {e.printStackTrace();}}/** *//*** Open the window*/public void open() {final Display display = Display.getDefault();createContents();shell.open();yout();while (!shell.isDisposed()) {if (!display.readAndDispatch())display.sleep();}}/** *//*** Create contents of the window*/protected void createContents() {shell = new Shell();shell.setSize(411, 359);shell.setText("SWT Application");text = new Text(shell, SWT.BORDER);text.setBounds(197, 109, 142, 25);text_1 = new Text(shell, SWT.BORDER|SWT.PASSWORD);text_1.setBounds(197, 173, 142, 25);final Button button = new Button(shell, SWT.ABORT);button.setText("提交");button.setBounds(85, 263, 48, 22);final Button button_1 = new Button(shell, SWT.ABORT);button_1.addSelectionListener(new SelectionAdapter() {public void widgetSelected(final SelectionEvent e){}});button_1.setText("取消");button_1.setBounds(247, 263, 48, 22);final Label label = new Label(shell, SWT.NONE);label.setText("用户名");label.setBounds(106, 112, 48, 22);final Label label_1 = new Label(shell, SWT.NONE);label_1.setText("密码");label_1.setBounds(106, 176, 48, 25);button.addSelectionListener(new SelectionAdapter() {public void widgetSelected(final SelectionEvent e){if(text.getText()!=""|text_1.getText()!="")//调用JFace的对话框显示登录信息MessageDialog.openInformation(shell,"登录信息","欢迎"+text.getText()+"进入系统!");else//调用JFace的对话框显示出错信息MessageDialog.openError(shell,"错误","用户名或密码为空,请重新输入!");}});}}开发实例3:开发环境Eclipse3.2,英文版。

SWT(Standard Widget Toolkit),标准窗口小部件工具包。

本例将创建第一个SWT程序。

本实例是一个简单的界面,在窗口显示【hello,SWT】字样。

Display负责监管CPU资源并管理和操作系统的通信,关注窗口的显示、移动、重画,确保鼠标的点击、键盘的敲击等事件送达到小部件并去处理他们。

Display类是不可见的。

Shell类扮演GUI主窗口的角色。

一个Shell实例是一个可视化的应用,对主窗口的打开,激活,最大化,最小化和关闭保持追踪。

Shell类的主函数为整合GUI内的容器、小部件和事件提供一个通用的接入点。

实例包括3部分:1.新建一个项目名为“SWT”的项目。

2.引入SWT包要编写SWT程序,需要引入SWT的jar包。

在完整的Eclipse开发环境中才能得到SWT包。

它作为一个插件的形式存在。

在Eclipse 3.2中它路径是eclipse-SDK-3.2-win32plugins;插件名为org.eclipse.swt.win32.win32.x86_3.2.0.v3232m.jar。

(1)右击【SWT】项目,选择【Properties】——弹出【Properties for SWT】对话框(2)在左侧列表中选择【Java Build Path】——选择【Libraries】选项卡——选择【Add Variable】——弹出【New Variable Classpath Entry】对话框(3)点击【Configure Variables】——弹出【Preferences】对话框(4)点击【New】——弹出【New Variable Entry】(5)在【Nam e】中键入“SWT_LIB”——单击【File】,弹出【JAR Selection】,选择org.eclipse.swt.win32.win32.x86_3.2.0.v3232m.jar。

单击【OK】,返回上级,依次单击【OK】(6)SWT_LIB 变量就放入了【Properties for SWT】对话框的【JARs and clas s folders on the build path】中。

3.编写程序4.SWT调用了操作系统自带的图形库,因此在运行程序的过程时需要指出本机图形库的位置。

位于org.eclipse.swt.win32.win32.x86_3.2.0.v3232m.jar包中,为了能够确保这些库文件能够被程序使用,可以将本机图形库放进java.library.path变量所包含的任何目录中。

(1)解压org.eclipse.swt.win32.win32.x86_3.2.0.v3232m.jar至任意目录中,如:E:s wt目录中。
