Hi list, I'm trying to draw lines on a text view.
In my current solution I have placed a transparent drawing area on top of the text view. This does work unless the compositor is different from mutter (I guess). As a result in XFCE the drawing area isn't transparent while in Cinnamon and Unity I get the expected result. Someone who used gtk2 managed to draw into the textview's 'expose-event' ( http://stackoverflow.com/questions/2027379/draw-lines-on-gtk-textview ). But using gtk3's 'draw-event' I can't come any close to his approach. 'drawable' has been abandoned and if I do anything inside the 'draw-event', the whole content of the textview will be replaced by the new cairo buffer. Anyway to mix the old content? I realized there's a 'draw_layer()' virtual function in gtk 3.14 and using it with the condition 'GTK_TEXT_VIEW_LAYER_ABOVE' is very much what I need. But I don't think I can update my libraries that easily, especially because I need to create win32 compiles of my app soon. So if you can point me to a way on how to draw lines on a textview using gtk3 but without the need of a compositing manager and without new versions like 3.14, I'd be very glad. My gtk3 lib is 3.8, I'm using Vala but I'll be glad about any C- or Python-example as well. I should be able to adopt it after all. Thanks a bunch in advance. gilzad _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
