Hi,
I have an problem on ppc with a table and a popup menu.
The problem is the popup menuitem 'Pay' which should only enabled if the
person has open payments.
I discovered that the following method on Pocket PC will invoke only once
menuPopup.addListener(SWT.Show, new Listener() {
public void handleEvent(Event event) {
and then the popup menu is always the same.
Or more in detail:
- start programm ==> popup menu on john or frank ==> the 'pay' item is
now for all persons disabled
- start programm ==> popup menu on bill ==> the 'pay' item is now for
all persons enabled
Is this a bug or pocket pc behaviour and exists an workaround for this?
I have Windows Mobile 2003, Second edition - Version 4.21.1088 (Build
14260.2.0.5) and SWT 3.0.1 for PPC. On PC the snippet works right.
Will this SWT version influence in the eRCP project?
Many thanks,
Frank
