Change interface font in a GTK application at runtime without reopening windows
A lot of users are asking me for the capability to change the font of an application runtime. I know that the correct answer should be change your gtk theme or edit the application RC file, but while this kind of answer is good with power users, normal users often want to be able to grab a font from a list and quickly try it on the REAL application interface without the need of a restart. I know that I can change the font of a single widget with gtk_widget_modify_font(), and that I can change the font of EVERY future widget with something like: gtk_rc_parse_string(gtk-font-name=\sans 13\\n); But what if I want to change the font of the actual interface without having to close all the application window and open them again? I'm quite sure it's possible since I've seen a few apps doing it. Sadly I don't remember the apps, otherwise I'd go peek at their sources :) I think there should be cleaner way that a full iteration on the widget tree of every window and a gtk_widget_modify_font() Call on each widget, isn't it? :) Bye, Gabry ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Problems in GdkWindow Events with Gtk - DirectFb backend
Hi,
I am facing an issue to get events on GdkWindow which was built with
Gtk DirectFb backend.
In sample program i am creating a toplevel GdkWindow and creating a
child Gdkwindow.
While creating GdkWindow i have added events mask, and used
gdk_window_add_filter() function to add event handler callback to
GdkWindow.
While running executable I am not getting any events (Key press,
expose, button press etc..).
With same program we are getting events on Gtk - X11 backend.
Is Events handling implementation for GdkWindow with DirectFb backend
implemented or not?
Please suggest me how to get events on GdkWindow with DFB backend.
Sample program is this-
#include gtk/gtk.h
#include gdk/gdk.h
GdkFilterReturn child_handle_event( void *event1, GdkEvent *event2,
gpointer userdata )
{
g_printf(child_handle_event\n);
}
int main(int argc, char* argv[])
{
GdkWindow *parent, *child;
GdkWindowAttr attr;
gtk_init(argc, argv);
attr.event_mask = GDK_VISIBILITY_NOTIFY_MASK | GDK_EXPOSURE_MASK |
GDK_POINTER_MOTION_MASK | GDK_POINTER_MOTION_HINT_MASK |
GDK_BUTTON_PRESS_MASK |
GDK_BUTTON_RELEASE_MASK | GDK_KEY_PRESS_MASK | GDK_KEY_RELEASE_MASK |
GDK_ENTER_NOTIFY_MASK | GDK_LEAVE_NOTIFY_MASK ;
attr.x = 100;
attr.y = 100;
attr.width = 800;
attr.height = 600;
attr.window_type = GDK_WINDOW_TOPLEVEL;
attr.wclass = GDK_INPUT_OUTPUT;
parent = gdk_window_new (NULL, attr, GDK_WA_X | GDK_WA_Y);
attr.event_mask = GDK_VISIBILITY_NOTIFY_MASK | GDK_EXPOSURE_MASK |
GDK_POINTER_MOTION_MASK | GDK_POINTER_MOTION_HINT_MASK |
GDK_BUTTON_PRESS_MASK |
GDK_BUTTON_RELEASE_MASK | GDK_KEY_PRESS_MASK | GDK_KEY_RELEASE_MASK |
GDK_ENTER_NOTIFY_MASK | GDK_LEAVE_NOTIFY_MASK;
attr.x = 200;
attr.y = 200;
attr.width = 400;
attr.height = 300;
attr.window_type = GDK_WINDOW_CHILD;
attr.wclass = GDK_INPUT_OUTPUT;
child = gdk_window_new (parent, attr, GDK_WA_X | GDK_WA_Y);

Re: Slow UI updates with GtkImage
On Nov 27, 2007 6:11 AM, David Brigada [EMAIL PROTECTED] wrote: Hi, I'm working on an audio player application. I currently have two elements that change on a frequent basis: a GtkHScale and a GtkImage. Whenever I update the data, I call gtk_widget_queue_draw on the widget that changed. With just the slider updating every 200ms, it works fine. If I add the GtkImage changing (by swapping out the GdkPixbuf with gtk_image_pixbuf_set) or I call gtk_widget_queue_draw on the widget, the UI waits about 2.5s in between redraws on both the slider and the image. This event happens about every 186ms. Is there something that I should be doing differently here? Is this method horribly inefficient? What should I change? You should not have to call gtk_widget_queue_draw() at all in this case (I'm sure the gtkimage gtkscale implementations do this themselves when you update the image or adjustment values). Rather, how is your application structured ? do you use a thread for the audio or are you processing audio data for 2.5s intervals before ever returning control to the gtk+ main loop ? (are you blocking or read or write maybe ?). Even if you get it all right though, remember that you can still get resource starvation when writing a media streaming app, probably your audio processing thread is a higher priority.

Lots of GCd languages have GTK bindings these days. Just because a language or library implements garbage collection doesn't mean you don't need to manage resources. Especially when you're working with a GUI. It's totally possible to leak memory in Python, C# or any other managed language if you don't know what you are doing. It's a bit harder, but still a problem. Recently the Darpa autonomous vehicle challenge was lost by one group because their C# control system was leaking very badly, requiring a restart every 30 minutes or so. GTKmm is based on some very nice C++ abstractions around pointers, providing many of the same benefits as any managed language with pure C++. They are called smart pointers and for GUI development, they work very very well. I find GTK in C++ to be almost as productive as python or C# Incidentally, has anyone tried GTK# from C# on Mono? Yup. It works awesomely well. It's very clean. Of course I can't think of many reasons to do it anymore.
