Re: Display Raster Data?

I suggest you use GStreamer, you can build a video by pushing bitmap frames and it does everything else for you. Otherwise, you can animate a DrawingArea. Set up a 60hz timer on your own. The timer callback simply calls gtk_widget_queue_draw_area()

Re: Display Raster Data?

I should point out that the draw_func may be called by Gtk whenever it needs, The best is to have the timer callback change the "current" bitmap and call gtk_widget_queue_draw_area(). Then on the drawing callback of the drawing area you just paint the "current" bitmap. 2018-08-01 15:44 GMT+02:0

Re: Emitting signals from threads

Hi Mitko, last time I tried creating a simple C application for testing but I did get always correct values. (Btw I used g_idle_add) Can you try to write a minimal test application that still exhibits the problem? That would be very helpful! ___ gtk-list

Re: Window having unnecessary space

Try running your application with environment variable GTK_DEBUG=interactive This loads the inspector, with that you can see the tree of widgets and their space/allocationsize. Luca Il giorno mar 29 gen 2019 alle ore 19:20 J.Arun Mani via gtk-list < gtk-list@gnome.org> ha scritto: > Hello. > Im

Re: Emitting signals from threads

Yes, go ahead. I don't know if that can be useful to you, but if you increase the time spent in usleep() to something greater it works correctly. With usleep(1) I get mixed results: Third column activated Third column activated Activated an other column Activated an other column Third column
