Hello, I recently posted a question on stackoverflow.com regarding GTK Warnings I recieve when running my application.
You can read full question here on this link <https://stackoverflow.com/questions/46253472/allocating-size-to-gtk-warning-when-using-gtk-treeview-inside-gtk-scrolledw>, but in short, I am developing an application in GTK3 using PyGObject, and the issue I'm having is with TreeView and ScrolledWindow widgets. I have TreeView widget inside ScrolledWindow which is inside a main grid, and whenever there are enough items in the TreeView for the scroll bar to appear, I get spammed with the following warnings: Gtk-WARNING **: Allocating size to __main__+MCVEWindow 0000000004e93b30 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate? MCVEWindow is an ApplicationWindow widget which contains aforementioned main grid. The warnings also appear whenever I expand all TreeView items leading me to believe it may be a layout/resizing issue. >From what we gathered so far, the issue is not reproducible in GTK version 3.18, but it is reproducible in versions 3.22.18 and 3.22.21. I also don't think it's a bug in my code, but rather in GTK itself although I'm new to GTK so I'm not quite sure. Python code is in the linked StackOverflow question, you should be able to copy&paste and run it, and a user on StackOverflow was kind enough to translate my code into C version <https://gist.github.com/mywtfmp3/bf17df5a3d13c889acd673740c9c2898>, which he tested on version 3.22.21. I was wondering if someone can point out the issue or confirm it's in fact a GTK bug, and if it is, where to report it.
