I've been using that signal since the very first commit of this source file, as a combined way to be notified when the size of the drawing area changes (typically due to user window resizing actions) and also when the drawing area is first created and available to be drawn on. Unfortunately, testing on Ubuntu 18.04, I ran into an oddity, in which the call to gtk_widget_show(inst->window) in new_session_window() has the side effect of delivering a spurious configure_event on the drawing area with size 1x46 pixels. This causes the terminal to resize itself to 1 column wide, and the mistake isn't rectified until a followup configure-event arrives after new_session_window returns to the GTK main loop. But that means terminal output can occur between those two configure events (the connection-sharing "Reusing a shared connection to host.name" is a good example), and when it does, it gets embarrassingly wrapped at one character per line down the left column. I briefly tried to bodge around this by trying to heuristically guess which configure events were real and which were spurious, but I have no faith in that strategy continuing to work. I think a better approach is to abandon configure-event completely, and move to a system in which the two purposes I was using it for are handled by two _different_ GTK signals, namely "size-allocate" (for knowing when we get resized) and "realize" (for knowing when the drawing area physically exists for us to start setting up Cairo or GDK machinery). The result seems to have fixed the silly one-column wrapping bug, and retained the ability to handle window resizes, on every GTK version I have conveniently available to test on, including GTK 3 both before and after these spurious configures started to happen. |
