Child windows? about ui

[cryptix]

I found a solution to emulate a MessageBox but it involves ui.Do() and thus I had to untangle my code so that the event handler is on another goroutine than the one which creates the main window, which might be a good idea anyway but i'd like some feedback on this.

My utility can be found here and here is some example usage.

The hiding of the parent window is debatable but It's less hassle than deactivating all the controls in it.

The main reason why I have not reimplemented message boxes is because ui.OpenFile() still doesn't work correctly. Disabling controls will also come later.

As for child windows, I'm not entirely sure what you are asking...?

Aaah, I see. Okay.

Okay, the issue title is missleading/wrong. The question was how to get modal dialogs / lock the parent.

I'm definitely not a fan of those in general but they fit the job quite nicely if you want to focus the user on an error that can't be recovered from.

Right; modal dialogs are not in for the same reason (ui.OpenFile() not working correctly; it has to do with some weirdness with modality).

I'll take a look at your code again and comment on it sometime today.
