gtk3

How can I customize the completion of a GtkComboBoxText with both a "static" aspect and a "dynamic" one? The static aspect is because some entries are known and added to the combo-box-text at construction time with gtk_combo_box_text_append_text . The dynamic aspect is because I also need to complete thru some callback function(s), that is to complete dynamically -after creation of the GtkComboBoxText widget- once several characters has been typed. My application uses Boehm's GC (except for GTK objects of course) like Guile or SCM or Bigloo are doing. It can be seen as an experimental

I'm experimenting with using the GtkGLArea widget at the moment. None of the answers to similar questions seem to pertain to this situation. glClear() can set the background colour just fine but actually drawing arrays of triangles isn't. According to this tutorial, the code below should work. EDIT: 21/5/2015: Added shaders, still getting same results. New code below Here's the main.c and the SConstruct so you can build with scons: SOLVED: Working code under the heading SOLUTION: main.c the same SConstruct file can be used to build example main.c #include <stdlib.h> #include <stdio.h> #include

With the release of Gtk 3 for windows I thought of upgrading my Gtk 2 C application to take advantage of the new GtkGrid widget. The program compiles fine under linux or using MinGW (with codeblocks) under windows, however when I try the same set of files under Visual Studio 2012, giving me 50 or so compilation errors saying gutils.h, gtrashstack.h and gstring.h have a bunch of syntax errors (assuming I only use a basic program, with just a gtk_init and gtk_main). Visual Studio handled gtk2 very well. Why is it refusing to compile with gtk3? Any way to get it to work with it? As much as I love

I have a small application that uses a DrawingArea to draw a simple map using PyGObject and GTK3 . I load a Pixbuf using from gi.repository import Gtk, GdkPixbuf pixbuf = GdkPixbuf.Pixbuf.new_from_file_at_size("logo.png", 25, 25) and then try to draw it in the DrawingArea 's draw event signal def draw(self, widget, context): window = widget.get_window() ctx = window.cairo_create() ctx.set_source_pixbuf(pixbuf, 0, 0) but I get the error message "AttributeError: 'cairo.Context' object has no attribute 'set_source_pixbuf'" If I'm reading the Gtk2 to Gtk3 migration guide correctly, this should

I'm trying css in gtk3 and I don't understand how to use specific class. C code: provider = gtk_css_provider_new(); display = gdk_display_get_default(); screen = gdk_display_get_default_screen (display); gtk_style_context_add_provider_for_screen (screen, GTK_STYLE_PROVIDER(provider), GTK_STYLE_PROVIDER_PRIORITY_USER); gtk_css_provider_load_from_path(GTK_CSS_PROVIDER(provider),"styles.css",NULL); enter_button = gtk_button_new_with_label("Print"); g_signal_connect(G_OBJECT(enter_button), "clicked", G_CALLBACK(print_entry_dialog),&t_data); gtk_box_pack_start(GTK_BOX(hbox3), enter_button, TRUE,

I would like to make the background transparent, and only the widgets are visible. Here is my code: #include <gtk/gtk.h> int main (int argc, char *argv[]) { gtk_init (&argc, &argv); GtkWidget *window = gtk_window_new (GTK_WINDOW_TOPLEVEL); // Title gtk_window_set_title(GTK_WINDOW (window), "Transparency"); //gtk_window_set_opacity(GTK_WINDOW(window), 0.5); // CSS GtkCssProvider *provider = gtk_css_provider_new(); GdkDisplay *display = gdk_display_get_default(); GdkScreen *screen = gdk_display_get_default_screen(display); gtk_style_context_add_provider_for_screen(screen, GTK_STYLE_PROVIDER

Trying to setup GTK+ 3.0 on Codeblocks Win7. Having some trouble finding exactly how to do this. The GTK website directs you to msys2. It seems there was once a direct download on the GTK site for an all-in-one Windows bundle that is no longer there. Having followed the instructions, installed and updated msys2, I see no reference to GTK+, in the installed files or on the mysys website that GTK directs you to. Its seems very linuxy in terms of being unnecessarily and stupidly unclear to do something that should be simple. Maybe im missing something but should it not be as simple as downloading

Possible Duplicate: Gigantic Tabs in Eclipse on Ubuntu Back when I was using Eclipse on Ubuntu 10.04 LTS, I found that the tabs and bars used a bit too much vertical spacing, which made the interface a bit too spacey for my taste. However, I didn't find a good way to make this right, and I learned to work with it. But now, after installing Ubuntu 12.10 (or actually Linux Mint 14 Cinnamon), it has gotten even bigger, the vertical spacing. If you have three tabbed windows with two toolbars in your normal vertical workspace, this easily hides 6 lines of code with useless UI spacing, which I

Unfortunately, I am using Windows (Windows7 x64). With MinGW compiler in Code::Blocks and GTK+3.6.4. I compiled manually all the schemas from glib. When I use File Chooser dialogue / colorpicker - it doesn't matter, I am getting the following error: GLib-GIO-ERROR**: No GSettings schemas are installed on the system and the program terminates. What do I have to do to fix this? GSettings looks at the compiled schemas in the directories pointed by the $XDG_DATA_DIR environment variable. You can either use a launcher script that sets up the environment for you, or you can rely on the prefix, and
