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();
}
}
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);
else
sashForm2.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();
}
}
