toga-demo fails with gtk backend #6

Closed apollo13 closed 8 years ago

I am getting this on debian stable:

Traceback (most recent call last):

Seems like width is not what it is supposed to be, I'll take a look later, this is just so it does not get lost :D

Hrm. That's really odd. What distro and version of Linux are you using?

This was on debian stable (at home). Running on unstable @ the office with your latest fixes works nicely but results in a lot of:

(toga-demo:3351): Gtk-WARNING **: Allocating size to GtkButton 0x1eb96c0 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate?
freakboy3742 commented 8 years ago

Hrm... that's an interesting bug. Do these messages just get printed once, or do you seem more instances whenever you resize the window or the split pane?

Also - what's the current GTK+ version on Unstable?

Moving this to pybee/toga-gtk#11
