SWT(JFace)体验之Sash(活动控件)

演示代码如下：

package swt_jface.demo9; import org.eclipse.swt.SWT; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Event; import org.eclipse.swt.widgets.Listener; import org.eclipse.swt.widgets.Sash; import org.eclipse.swt.widgets.Shell; public class SashExample {public static void main(String[] args) {Display display = new Display();Shell shell = new Shell(display);final Sash sash = new Sash(shell, SWT.BORDER | SWT.VERTICAL);sash.setBounds(10, 10, 15, 60);sash.addListener(SWT.Selection, new Listener() {public void handleEvent(Event e) {System.out.println("Selected. ");sash.setBounds(e.x, e.y, e.width, e.height);}});shell.open();sash.setFocus();while (!shell.isDisposed()) {if (!display.readAndDispatch())display.sleep();}display.dispose();} }

再来一个例子：

package swt_jface.demo9; import org.eclipse.swt.SWT; import org.eclipse.swt.custom.SashForm; import org.eclipse.swt.events.ControlEvent; import org.eclipse.swt.events.ControlListener; import org.eclipse.swt.events.MouseEvent; import org.eclipse.swt.events.MouseListener; import org.eclipse.swt.layout.FillLayout; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Label; import org.eclipse.swt.widgets.Shell; import org.eclipse.swt.widgets.Text; public class SashFormExample {Display display = new Display();Shell shell = new Shell(display);SashForm sashForm;SashForm sashForm2;public SashFormExample() {shell.setLayout(new FillLayout());sashForm = new SashForm(shell, SWT.HORIZONTAL);Text text1 = new Text(sashForm, SWT.CENTER);text1.setText("Text in pane #1");Text text2 = new Text(sashForm, SWT.CENTER);text2.setText("Text in pane #2");sashForm2 = new SashForm(sashForm, SWT.VERTICAL);final Label labelA = new Label(sashForm2, SWT.BORDER | SWT.CENTER);labelA.setText("Label in pane A");final Label labelB = new Label(sashForm2, SWT.BORDER |SWT.CENTER);labelB.setText("Label in pane B");text1.addControlListener(new ControlListener() {public void controlMoved(ControlEvent e) {}public void controlResized(ControlEvent e) {System.out.println("Resized");//ArrayUtil.printArray(sashForm.getWeights(), System.out);}});sashForm.setWeights(new int[]{1, 2, 3});labelA.addMouseListener(new MouseListener() {public void mouseDoubleClick(MouseEvent e) {if(sashForm2.getMaximizedControl() == labelA)sashForm2.setMaximizedControl(null);elsesashForm2.setMaximizedControl(labelA);}public void mouseDown(MouseEvent e) {}public void mouseUp(MouseEvent e) {}});shell.setSize(450, 200);shell.open();while (!shell.isDisposed()) {if (!display.readAndDispatch()) {display.sleep();}}display.dispose();}public static void main(String[] args) {new SashFormExample();} }
