I had a similar problem that I posted to GTK-list a while back, and
no-one really gave me a satisfactory response other than "you should use
themes to do this." Well, no, I want it to be a static property of
the app so themes aren't an option. What I wanted to do is set
the color of the text and background of a gtk_entry by doing (I thought):
time = gtk_entry_new ();
style = gtk_style_new ();
style->font = gdk_font_load
style->text[GTK_STATE_NORMAL].red = 0;
style->text[GTK_STATE_NORMAL].green = 1;
style->text[GTK_STATE_NORMAL].blue = 0;
style->bg[GTK_STATE_NORMAL] = style->black;
gtk_widget_set_style (time, style);
You see, I want my time display to have alien green digits (this is for a
CD Player) on a black background...but this doesn't work! I DO NOT want
this to vary with the themes, so theming to this isn't an option. I want
to know how to do this (and, generallly, set the attributs of any widget
like this) PROGRAMMATICALLY. Any ideas?
