Re: keyboard shortcuts with CTRL
Hi Marcin,
We are using shortcut keys in our application. I have written the below
code which uses CTRL+S. But there is an additional requirement that when
the window is opened using the same CTRL+S the window should close. Is this
possible. How do we do something like this.
Event.addNativePreviewHandler(new Event.NativePreviewHandler() {
@Override
public void onPreviewNativeEvent(Event.NativePreviewEvent event) {
NativeEvent ne = event.getNativeEvent();
final int eventType = event.getTypeInt();
boolean keyHandled = false;
switch (eventType) {
case Event.ONKEYDOWN:
if (ne.getCtrlKey()) {
switch (ne.getKeyCode()) {
case 's':
case 'S':
ne.preventDefault();
Scheduler.get().scheduleDeferred(new
ScheduledCommand() {
@Override
public void execute() {
processSearchEvents(params);
}
});
break;
}
}
}
}
});
Thanks,
Rahul

Actually it's very easy :
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

@Override
public void execute() {
loggerWindow.show();
}
});
}
}
});
CTRL+l oraz CTRL+L - opens the window with log messages.

only works on Chrome right, I thought, so I didn't really believe in

Then I saw Microsoft releasingkeyboardshortcuts in Hotmail. I tried

But today I saw Microsoft releasing their Word, Excel... Office suite
on-line (search for Office Web Apps). I tried CTRL+B and it put my

Chrome.
Now, some proof that it doesn't really work all of the time: I
selected the text on the top of the page, hit CTRL+S and nothing
happens... there goes my belief in in-browserkeyboardshortcuts
again.
I guess thekeyboardlistener is only put on the textarea and ribbon
bar and not a true browser window listener.
Still, my question stands:
how can I blockkeyboardshortcuts like CTR+O, CTRL+N and do something
with them instead of letting the browser handle them (CTRL+N typically
opens a new browser window, I don't want that)? Any advice is much
appreciated.

Re: keyboard shortcuts
I have just recently discovered the onPreviewNativeEvent() method which allows you to capture key presses without registering a KeyDownHandler. Off the top of my head, I do not recall which widgets specifically support this. I have been using it in my Dialog widgets. You will need to override this method in your implementation. I have not used to for determining combinations of keys (Ctrl+key, function keys, etc.) but it may work. - Matt On Tuesday, October 16, 2012 3:50:28 PM UTC-4, vanessa vanessa wrote: Hi all, I have to implement specefic keyboard shortcuts to my web application.

Hosted Mode - Keyboard Shortcuts?
Are there keyboard shortcuts in the hosted mode browser? In particular, for 'Refresh'? ⌘R doesn't do the trick in OS X. I haven't had a lot of luck searching for GWT hosted mode browser keyboard shortcuts in general.
