bug in gtk 1.2 still in gtk 1.3 - code example to show it

[Manuel Clos <llanero jazzfree com>]

Hi all,

I have many times reported that if you got the mouse just where the 
button is going to appear (gdm, nautilus-installer, ...) you won't be 
able to click the button, it is confusing and anoying.

Here is a simple example showing it. It raises a big window with a 
button on it (set_sensitive = false). After 2 seconds, a timeout makes 
the button sensitive. If you have the mouse over the button before the 
timeout sets it sensitive, you WON'T be able to click the button, it 
will refuse to do so. Leaving the button and entering it again makes it 
work.

I will love to fix it myself, but I don't have the skills.

As perhaps it is not a simple fix, I'm sending the bug here.

Try it out. Don't know if this applies to other widgets as well.

gcc button.c `gtk-config --cflags gtk` `gtk-config --libs gtk` -o button-bug

gcc button.c `pkg-config --cflags gtk+-2.0` `pkg-config --libs gtk+-2.0` 
-o button-bug

Thanks.
