eclipse插件开发用到图形界面的时候需要SWT,因此这里记录下开发环境然后写一个demo以便以后快速搭建工作环境:
关于开发环境,本人也看了几篇帖子,要安装个什么windowsbuilder,网址http://download.eclipse.org/windowbuilder/WB/release/R201309271200/3.7/
但是昨晚测试了一下,不知道是不是网络问题,没有能快速下载,然后找csdn下载了一个,选择archive安装,但是还是不好使,觉得没必要折腾,就找了个现成的,已经搭建好环境的eclipse3.5,传上去以后直接拿来用,http://pan.baidu.com/s/1c0loOsK
主要还是有个界面可以拖拽一下位置,
建议不要用它来拖出组件,因为会生成一个
private static final FormToolkit formToolkit = new FormToolkit(Display.getDefault());
这样一来会和我下面的代码产生冲突,这里如果是SWT高手可能会对我进行批评,因为我的代码比较生硬,我确实没搞过SWT,所以仅仅是能用,没有考虑质量的问题,建议新手就像我这样来,避免不必要的麻烦:
package com.xjz.genecode; 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.DirectoryDialog; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Label; import org.eclipse.swt.widgets.Shell; import org.eclipse.swt.widgets.Text; import org.eclipse.wb.swt.SWTResourceManager; public class UIMain { public static void main(String[] args) { /** * 初始化Display和Shell */ Display display = new Display(); final Shell shell = new Shell(display, SWT.CLOSE); shell.setSize(600, 200); int[] location = getCenterLocation(shell);//居中 shell.setLocation(location[0], location[1]); shell.setText("代码生成");//窗口标题 /** * XML路径选择栏 */ Label lblXMLSrc = new Label(shell, SWT.CENTER); lblXMLSrc.setFont(SWTResourceManager.getFont("微软雅黑", 12, SWT.NORMAL)); lblXMLSrc.setLocation(29, 38); lblXMLSrc.setSize(130, 23); lblXMLSrc.setText("\u9009\u62E9XML\u8DEF\u5F84\uFF1A"); final Text txtXMLSrc = new Text(shell, SWT.NONE); txtXMLSrc.setBounds(183, 38, 259, 23); Button btnXMLSrc = new Button(shell, SWT.NONE); btnXMLSrc.setBounds(463, 37, 80, 27); btnXMLSrc.setText("\u9009\u62E9"); btnXMLSrc.addSelectionListener(new SelectionAdapter() { public void widgetSelected(SelectionEvent e) { DirectoryDialog dirDialog = new DirectoryDialog(shell, SWT.OPEN); dirDialog.setFilterPath("SystemRoot"); txtXMLSrc.setText(dirDialog.open()); } }); /** * 代码生成路径指向栏 */ Label lblCodeTo = new Label(shell, SWT.CENTER); lblCodeTo.setFont(SWTResourceManager.getFont("微软雅黑", 12, SWT.NORMAL)); lblCodeTo.setLocation(29, 74); lblCodeTo.setSize(130, 23); lblCodeTo.setText("\u751F\u6210\u8DEF\u5F84\u6307\u5411\uFF1A"); final Text txtCodeTo = new Text(shell, SWT.NONE); txtCodeTo.setBounds(183, 74, 259, 23); Button btnCodeTo = new Button(shell, SWT.NONE); btnCodeTo.setBounds(463, 73, 80, 27); btnCodeTo.setText("\u9009\u62E9"); btnCodeTo.addSelectionListener(new SelectionAdapter() { public void widgetSelected(SelectionEvent e) { DirectoryDialog dirDialog = new DirectoryDialog(shell, SWT.OPEN); dirDialog.setFilterPath("SystemRoot"); txtCodeTo.setText(dirDialog.open()); } }); /** * 按钮一键生成代码 */ Button createCodeBtn = new Button(shell, SWT.CENTER); createCodeBtn.addSelectionListener(new SelectionAdapter() { @Override public void widgetSelected(SelectionEvent e) { Main.geneCode(txtXMLSrc.getText() ,txtCodeTo.getText()); } }); createCodeBtn.setText("\u4E00\u952E\u751F\u6210"); createCodeBtn.setBounds(170, 120, 259, 27); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) { display.sleep(); } } display.dispose(); } private static int[] getCenterLocation(Shell shell) { int width = shell.getMonitor().getClientArea().width; int height = shell.getMonitor().getClientArea().height; int x = shell.getSize().x; int y = shell.getSize().y; if (x > width) { shell.getSize().x = width; } if (y > height) { shell.getSize().y = height; } int[] locations = new int[2]; locations[0] = (width - x) / 2; locations[1] = (height - y) / 2; return locations; } }
运行结果:
解释必要点:
SWT程序入口就是Display和Shell,所以一开始就创建好固定的写法,然后要什么按钮控件自己再往上添加即可。
