Hi!
I made my own custom tooltip in SWT for an Eclipse-plugin. It works fine overall however I bumped into an issue:
I'm attaching a listener to the Text (which has a V_Scroll with it) which is inside a shell. The problem is that when I move the mouse over the vertical scrollbar the shell is disposed. I don't want that.
This is the code:
popup = new Shell(PlatformUI.getWorkbench().getDisplay(), SWT.TOOL );
popup.setLayout(new FillLayout());
Text text = new Text(popup, SWT.MULTI | SWT.READ_ONLY | SWT.WRAP | SWT.V_SCROLL);
text.setBackground(new org.eclipse.swt.graphics.Color(PlatformUI.getWorkbench().getDisplay(), 255, 255, 204));
text.addMouseTrackListener(new MouseTrackListener() {
public void mouseHover(MouseEvent e) {
}
public void mouseExit(MouseEvent e) {
popup.dispose();
}
public void mouseEnter(MouseEvent e) {
}
});
popup.setSize(200, 100);
text.setText("The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog");
popup.open();
How can I resolve this? I've been trying to find a way for a long time now but no solution 
Thanks and regards,

Hi,
The only way I can think of to do what you want is with an approach like
below. It's not pretty but it seems to work.
static Runnable runnable = null;
static int INTERVAL = 99;
public static void main(String[] args) {
final Display display = new Display();
final Shell shell = new Shell(display, SWT.TOOL);
shell.setLayout(new GridLayout());
final Text text = new Text(shell, SWT.MULTI | SWT.READ_ONLY | SWT.WRAP |
SWT.V_SCROLL);
text.setLayoutData(new GridData(200,200));
text.addListener(SWT.MouseExit, new Listener() {
public void handleEvent(Event event) {
if (display.getCursorControl() != text) {
System.out.println("exited via edge without scrollbar, so
hide it now");
} else {
runnable = new Runnable() {
public void run() {
if (text.isDisposed()) return;
if (display.getCursorControl() != text) {
System.out.println("exited scrollbar, so hide it
now");
} else {
display.timerExec(INTERVAL, this);
}
}
};
display.timerExec(INTERVAL, runnable);
}
}
});
text.addListener(SWT.MouseEnter, new Listener() {
public void handleEvent(Event event) {
if (runnable != null) {
display.timerExec(-1, runnable);
}
}
});
shell.pack();
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) display.sleep();
}
display.dispose();
}
HTH,
