add_widget() doesn't remove focus from the previously focused widget

[mooffie]

The problem:

When adding a new widget to a dialog, at runtime, add_widget() sets WST_FOCUSED on the new widget, but doesn't clear it from the previously focused widget. The result is two (or more) widgets that think they're the focused ones.

Seeing it:

Open the editor with some file. [You can use the mouse to carry out the following steps.] Turn off fullscreen for this WEdit and make is smaller. Now open another file in this same dialog (e.g., press C-n for a new file), and for this new WEdit too turn off fullscreen. Make this WEdit smaller so you can see the frames of both WEdits. You'll see that both frames have the color designated for a focused WEdit. Play with the mouse in both frames and you'll see that the problem gets fixed.

Note

The actual function is add_widget_autopos(), and that's how it's written in the commit message. For the ticket I wanted something "easier" in the title.

LGTM, only "in runtime", I think, is a typo in the original comment, and it should have been "at runtime", shouldn't it?

[mooffie]

(Right. I didn't want to fix the "in runtime" already there, in case this patch got rejected, so I doubled it as a signpost. If I get to commit this I'll fix the two errors.)

I propose another way: use widget_select() that changes focus and sets pointer to the new current widget.

(Folks: I fell ill. I'll be absent for several days.)

Being sick sucks, get well soon.

I'm back! My flu is almost over.

@Andrew: I checked your patch and it works. Do you want me to commit it? (if you want me to also rename 'current' to 'new_current' (I think it'd be clearer), say so.)

Replying to mooffie:

Yes, please.

[zaytsev]

I'm (obviously) +1 as long as you two are in agreement.
