Good morning everyone!
I'm having problems with updating the look of MenuItem smartgwt. I'm leaving
the subitems disabled and enabled dynamically, but the look is not, has
problems, only updates the look when the cursor is over the icon, but needs
to be updated to access the menu, follow what I'm trying to do:
2 subitems begin disabled and are only able to access another sub-item, but
in doing so enabled this subsection which sets should be disabled.
They are disabled but the bigger problem is the question that is not dynamic
visual ... How do I pose to fix it?
The other problem is concerned a repetition of events from the keyboard, how
can I do to run a command only while precione is the shortcut key that I
generated?
HandlerRegistration logHandler = Event.addNativePreviewHandler(new
NativePreviewHandler() {
@Override
public void onPreviewNativeEvent(NativePreviewEvent
event) {
NativeEvent ne = event.getNativeEvent();
if (ne.getCtrlKey() && (ne.getKeyCode()=='l'
||
ne.getKeyCode()=='L')) {
ne.preventDefault();
DeferredCommand.addCommand(new
Command() {
@Override
public void execute() {
loggerWindow.show();
}
});
}
}
});
And the last problem is with the gwt-print: cmo do I print full pages in
firefox? They are coming out blank!
