colors and tool buttons/menu items

[Marisa DeMeglio <marisa dinf ne jp>]

I'm modifying some colors in my application (though the app's default 
state is the selected theme, i want to provide some simple way to change 
the color of a few items) and I'm having trouble with the following:
I'm using gtk_widget_modify_fg()  and gtk_widget_modify_bg() for all of 
the widgets mentioned.
toolbar buttons: i can change the color of the whole toolbar but the 
individual buttons still turn gray when moused over and pressed.   
attemps to alter the toolbutton widget itself don't make a difference (i 
tried GTK_STATE_NORMAL, GTK_STATE_PRELIGHT,  GTK_STATE_ACTIVE).  when i 
use gtk_tool_button_get_label_widget(), i don't get a valid widget 
returned, otherwise i would try setting at least the fg color of the text.
menu items: the menubar itself is changing color, no problem.  I can set 
the foreground color on menu item labels.  However, the only menu item 
bg color I've been able to change is by using GTK_STATE_PRELIGHT, and 
this only changes color when the menu item is selected.  Otherwise bg is 
gray.
I'm using GTK 2.4 and WinXP. 

Any help would be much appreciated!

Thanks
