Hello All,
I am new to RAP and also to RCP. I wanted to find out if there is any
widget which will allow multiple selections on dropdown
or
when focus comes on a text-field we can create a list below that
text-field and allow user to select multiple items from that list.
I want to achieve this functionality in RAP. Currently I am using RAP
1.1 M1 target platform.
Please advice.
Thanks,
Arpit

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
