Question

Specifically, it behaves inconsistently regarding text field focus.

I have an LSUIElement popping up a status menu. Within that menu there is a view containing a text field. The text field needs to be selectable -- not necessarily selected by default, but whichever.

When the status item is clicked, it triggers

[NSApp activateIgnoringOtherApps:YES];

And it works, about half the time.* The other half the status menu seems to consider itself "in the background" and won t let me put focus on the text field even by clicking on it. (I know the status item click-trigger is firing b/c there s an NSLog on it.)

Is this a bug in the way Apple handles these status items, or am I mishandling activateIgnoringOtherApps?

*In fact, it seems to fail only the first time after another app is activated. After that it works fine.

The complete snippet:

-(void)statusItemClicked:(id)sender {
    //show the popup menu associated with the status item.
    [statusItem popUpStatusItemMenu:statusMenu];

    //activate *after* showing the popup menu to obtain focus for the text field.
    [NSApp activateIgnoringOtherApps:YES];

}

Answer 1

Finally came up with a workaround for this.

Instead of popping the menu in your click handler, activate the app then schedule an NSTimer with no delay that pops the menu:

-(void)pop:(NSTimer *)timer {
    [statusItem popUpStatusItemMenu:theMenu];
}

-(void)statusItemClicked:sender {
    [NSApp activateIgnoringOtherApps:YES];
    [NSTimer scheduledTimerWithTimeInterval:0.0 target:self selector:@selector(pop:) userInfo:nil repeats:NO];
}

pop: is called on the next frame so the delay is imperceptible but long enough for activateIgnoringOtherApps: to do whatever was preventing it from working as expected when popping the menu in the same frame.

Answer 2

I know from experience that you have to call activateIgnoringOtherApps: after you ve popped up the menu that contains your text field. So you would need to do it in this order:

- (void)statusItemClicked:sender {
    [statusItem popUpStatusItemMenu:theMenu];
    [NSApp activateIgnoringOtherApps:YES]; // FYI, NSApp is shorthand for [NSApplication sharedApplication]
}

Based on what you ve said, it sounds like your application is activating too late, so that it s not getting activated the first time you click on the item, but it is already activated on subsequent clicks.
