Sure it can. You can theme things in Gtk by class, widget_class, widget or their hierarchy, see gtkrc documentation: http://library.gnome.org/devel/gtk/unstable/gtk-Resource-Files.html Just name your button objects differently (e.g. redbutton and greenbutton) and set suitable theme for each object name. - Eero PS. For speed reasons, don't use patterns like "*name*", if needed, single "*" should be enough for a match pattern. ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
Re: How can I change the background color of a GtkButton when it is activated
What about connecting two signals to your button widget: pressed and released In the function for "pressed" change the background colour to blue. In the function for "released" change the background colour back to normal. http://library.gnome.org/devel/gtk/stable/GtkButton.html#GtkButton.signals I think this should do what you want, though I don't know if it is the optimal way.

Re: How can I change the background color of a GtkButton when it is activated
Hi, Dave, Thanks for your advice. However, my objective is to set two different colors for two different buttons. That is to say, for button A, when it is pressed, the color should be red; while for button B, in this case, the color should be green. Thus I do not think the GTK+ theme can solve this problem. Is there any other possible solutions? Thanks in advance.

Hi Yao, Yao Wang wrote: > The default color when I pressed down the button is blue.

The default colour for when the button is pressed is set by the GTK+ theme. I'd suggest changing the theme so that all buttons, when pressed, will be red. It's in general not a good idea to hack applications with hard-coded widget colours, and it's generally encouraged to write applications which are consistent with the rest of the environment. Hope this helps!

How can I change the background color of a GtkButton when it is activated
Hello everyone.
I am developing a GUI application on maemo, in which GtkButton is
used.
The default color when I pressed down the button is blue. I want to
change the background color of button when it is pressed and recover its
origin background color when it is released.
I tried to implemented it using the following code:
GdkColor color;
gdk_color_parse ("red", &color);
gtk_widget_modify_bg(GTK_WIDGET(button), GTK_STATE_ACTIVE, &color);
However, it dose not work at all.
Could anyone kindly give me some advices or suggestions ?
Thanks in advance.
