using SWT Label and popmenu to construct a menu

[bruce628]

I want to use SWT Label and popmenu to construct a menubar ,and the effect
of this menubar is same to the menubar in SWT.When click the Label,it should be highlighted and popmenu shows.The issue is when click the label and move the mouse to enter next label,the next label can not be highlighted.Can anyone have a solution for it?
Here is my code:
import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.*;

public class labelmenu {

protected Shell shell;
private menuComposite menucomposite;
private Display display;
/**
* Launch the application
* @param args
*/
public static void main(String[] args) {
try {
labelmenu window = new labelmenu();
window.open();
} catch (Exception e) {
e.printStackTrace();
}
}

/**
* Open the window
*/
public void open() {
display = Display.getDefault();
createContents();
shell.open();
shell.layout();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
}

/**
* Create contents of the window
*/
protected void createContents() {
shell = new Shell();
shell.setSize(500, 375);
shell.setText("SWT Application");

final Composite composite = new Composite(shell, SWT.NONE);
composite.setBounds(0, 0, 331, 54);

menucomposite = new menuComposite(display,composite, SWT.NONE);
menucomposite.setBounds(0, 2, 96, 20);
//

First of all, never post this much code, read the forum posting guidelines about that. In general though, if you had posted a small section of code that contained your problem I or anyone else would be more inclined to read it then if it's such a large amount.

Secondly, put your code in code brackets (when you post look to the right in the box that says "reply guidelines").

Now, I believe your problem has to do with the fact that you are not calling repaint or even have a paint method.

Check out this tutorial: http://java.sun.com/docs/books/tutor...concepts2.html

The only way to update any image color or draw something is to use the paint method and repaint to change what area you want.

Good luck,
