hi,
a first idea on how to achieve this: you could add a focus listener on the
text widget which opens a new shell at the coords of the text widget. the
shell only contains a check table with the selectable items. the shell
closes upon loosing its focus and returns an array of the selected items.
if you need help or some examples with the codebase pls report back :).
greetings and happy easter!

Hey Guys,
Here is a snippet of what I came up with but somehow its not working. I
am able to create and display the new shell but the List inside this new
shell is never displayed. I tried putting a simple text box too but that
didn't show up either.
What am I doing wrong here ?
Arpit
txtVersion.addFocusListener(new FocusAdapter() {
Shell sh;
Text widget;
List lst;
Composite c;
Display display;
public void focusGained(final FocusEvent event) {
widget = (Text)event.widget;
display = widget.getDisplay();
sh = new Shell(display.getCurrent().getActiveShell(), SWT.NO_TRIM);
System.out.println("x=" + widget.getLocation().x + "
y="+widget.getLocation().y);
sh.setLayout(new GridLayout());
sh.setLocation(widget.toDisplay(widget.getLocation()));
sh.setSize(widget.getSize().x, 100);
// Text t = new Text(sh, SWT.BORDER);
// t.setText("Typo");
lst = new List(sh, SWT.MULTI | SWT.V_SCROLL);
lst.setItems(new String[] { "1 - Hello", "2 - Hello", "3 - Hello",
"4 - Hello", "5 - Hello" });
lst.setVisible(true);
sh.open();
sh.redraw();
while (!sh.isDisposed()) {
if (!(display.readAndDispatch())) {
display.sleep();
}
}
}
@Override
public void focusLost(FocusEvent event) {
sh.close();
sh.dispose();
}
});

Hi,
which RAP-Version do you use? There was a bug #204556 that seems similar
to what you are describing. That bug is solved in CVS-Head. Just in
case...
Ciao
