"How does the code know the size to allocate?" from gtk_window_check_resize() under gtk_container_idle_sizer()
Submitted by Milan Crha @mcrha
Link to original bug (#770003)
Description
This is with gtk3-3.20.8-1.fc24. Running locally built test-html-editor from evolution-3.21.90/e-util (which is a noinst_PROGRAMS) shows a runtime warning:
(test-html-editor:25481): Gtk-WARNING **: Allocating size to GtkWindow 0x108d450 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate?
With the below backtrace. Maybe there is something what the editor does wrong, but I do not know how to debug this further, thus any help will be appreciated. Note that the GtkWindow's parent is NULL.
