Hi Steve,
My snippet is after this mail body. I did manage to get it working.
Some points:
- The PopupList.open(Rectangle) documentation is a bit confusing. It seemed
to me that it meant the size of the popup list rectangle that is drawn.
However, the height in the rectangle is interpretated to be the distance
below the x,y coordinates from which the popup list starts to get drawn.
Due to this if my code mentioned 100 it start drawing 100 units below the
mouse pointer. Finally, I reduced it to 10 so it would start drawing near
the mouse pointer. Thus, it was not a problem with Display class as I had
mentioned in my email.
- The PopupList 2 argument constructor seems to be having the following line
list = new List(shell, SWT.SINGLE | SWT.V_SCROLL);
Does it mean that the V_SCROLL is hardcoded into it and one cannot have a
H_SCROLL? I have
been unable to get the H_SCROLL working as yet.
Thank you
Regards,
Aashish
Code Snippet:
PopupList oldQueryListBox = new
PopupList(QueryView.this.getSite().getShell(), SWT.H_SCROLL | SWT.V_SCROLL);
oldQueryListBox.setItems(getOldQueryList());
String selectedQuery = oldQueryListBox.open(rect);
