Drawing and mouse in GTK HiDPI aware app (Xorg/Wayland)

Hello, my GTK application draws some bitmaps on a GtkDrawingArea, and receives mouse position events from the same widget (or its container widget). The application is running in a 2x HiDPI scaled desktop, so when the GtkDrawingArea has a logical size of WxH pixel, it's really taking 2*Wx2*H

Hi group, I'm having issues with gdk-pixbuf loader and JPEGs on my Windows 10 system with MSYS. The loader works okay to construct pixbufs. But for some reason, it refuses to emit area-updated and area-prepared until the jpeg is 100% loaded already. That kind of defeats the purpose of that

Indeed, gtk_text_buffer_insert_with_tags_by_name() does what it says. What I was talking about was (in some future Textview) applying the tag to an iter, then whenever the insert point was on that iter, it would inherit the tag properties set there. So typing at that point gets the formatting.
