gtk3

问题 I have a program (written in C, currently running on Mac OS X 10.8.4) that simulates a world and updates the world's state multiple times per second. At startup this program creates a background thread which creates a simple GTK window and calls gtk_main . After each time the world's state is updated (in the main thread), I would like the window to reflect that change. My first approach was to simply update the GTK widgets after the world was updated, but because that was in a different

问题 I've developed a gtk2 app (Conky Companion) in C to help users of my conky scripts Link: http://crunchbanglinux.org/forums/topic/19235/conky-weather-scripts-using-accuweatherwundergroundnwsweathercom/ create their own conkyrcs with relative ease.

问题 I'm trying to style a GtkSourceView object in particular I'd like to change the color of line numbers. I'm reading https://developer.gnome.org/gtksourceview/stable/style-reference.html.

问题 I was experimenting with assembly code and the GTK+ 3 libraries when I discovered that my application turns into a zombie if I don't link the object file with gcc against the standard library. Here is my code for the stdlib -free application %include "gtk.inc" %include "glib.inc" global _start SECTION .data destroy db "destroy", 0 ; const gchar* strWindow db "Window", 0 ; const gchar* SECTION .bss window resq 1 ; GtkWindow * SECTION .text _start: ; gtk_init (&argc, &argv); xor rdi, rdi xor

问题 I have a problem with quitting a gtk application. The function call of g_application_quit results in the subsequent error: GLib-GIO-CRITICAL **: g_application_quit: assertion 'G_IS_APPLICATION (application)' failed The code snippet looks like this: g_signal_connect(app_window, "destroy", G_CALLBACK(g_application_quit), app); I tried this also, but still throws the same error: g_signal_connect(app_window, "destroy", G_CALLBACK(g_application_quit), G_APPLICATION(app)); The app got initialized

问题 I create application in GTK+3 and I Would like to change the background color for GtkBox but can not here this code: box.modify_bg(Gtk.StateType.NORMAL, color); 回答1: In "Common Questions" of GTK+3 is the answer to your question. In the basic form, you can use: box.override_background_color(Gtk.StateType.NORMAL, Gdk.RGBA(.5,.5,.5,.5)) In this case, the color will be a soft grey, half transparent. Probably, you want to paint it during the draw signal. 来源： https://stackoverflow.com/questions
