I have an application that I am porting from GTK3 to GTK4.
It has two GtkDrawing widgets and a set of controls (in GtkBoxes on the left) (see below).
I have a radio button that chooses a different display that only uses one of the drawing widgets, so I make the second invisible. This leaves a lot of blank space that I want to remove by shrinking the GtkApllication widget to match the smaller content. (shrink wrap the application window). I can do this manually by grabbing the edge with the mouse and dragging it in (see bottom image) but I would like to do this programmatically.
I did this with GTK3 (with a lot of difficulty). Is it possible to do this with GTK4? If so how?
