Re: Change button color in button-press-event

[gtk digosp com]

I do have resource file with the following style:

style "ButtonStyle"
{
    font_name = "Sans 13"
    bg[SELECTED] = {0, 1.0, 0}
    bg[ACTIVE] = {0, 0, 1.0}
    bg[INSENSITIVE] = {0.5, 0.5, 0.5}
    fg[INSENSITIVE] = {0.5, 0.5, 0.5}
}

However that does not seem to work.

This is for an embedded device with touch screen, no mouse.
If I send activate signal from my code to a button, it turns blue and  
then back to its initial color, as expected.
When I press the button with my finger, I do get click event, but  
button color never changes.
I noticed that most of the time PRESS is received only when I remove  
my finger from the button.

Thank you,

D.
