This is how I set styles and switch between styles at runtime.
Let's say we want to put white text on a black background. We first have to
define the styles in a "style rc" file. (See testgtkrc in the testgtk example
of the pygtk distribution.)
-----------8<-----------
style "button_style"
bg[NORMAL] = { 0, 0, 0 }
bg[PRELIGHT] = { 0, 0, 0 }
bg[ACTIVE] = { 0, 0, 0 }
style "label_style"
font = "-adobe-helvetica-medium-r-normal--*-100-*-*-*-*-*-*"
fg[NORMAL] = { 1.0, 1.0, 1.0 }
fg[PRELIGHT] = { 1.0, 1.0, 1.0 }
fg[ACTIVE] = { 1.0, 1.0, 1.0 }
-----------8<-----------
Next, we make the widgets and use the "rc_parse_string" method. But make the
label a separate widget, and add it to the button. For some reason defining the
label with GtkButton('Label Name') is unreliable for switching styles at
runtime.
-----------8<-----------
button = GtkButton()
rc_parse_string('widget "*button*" style "button_style"')
button.set_name('button')
...
label = GtkLabel('I am a label!')
rc_parse_string('widget "*label*" style "label_style"')
label.set_name('label')
button.add(label)
-----------8<-----------
At any other point in our program, we can change the styles to others defined in
the style rc.
-----------8<-----------
rc_parse_string('widget "*button*" style "button_style2"')
button.set_name('button')
rc_parse_string('widget "*label*" style "label_style2"')
button.set_name('label')
-----------8<-----------
Maybe this isn't orthodox, but it works. BTW, for switching styles, it works
best to use "set_name" AFTER rc_parse_string, rather than before.
If anyone sees something wrong in the way I am doing this, that might explain
why labels have to be separate widgets and why set_name is used after
rc_parse_string, please let me know.
