Ruby Forum Ruby-Gnome 2 > progressbar color??

hi, this is a basic problem I think but I try to do this for long time.
after I declare

progress = ProgressBar.new

I use

progress.modify_fg(STATE_NORMAL,Gdk::Color.new(240*255,208*255,215*255))

but it's nothing happen

and when I do

progress.modify_bg(STATE_NORMAL,Gdk::Color.new(240*255,208*255,215*255))

color of background of progress bar is a color but I want color at bar
how can I do that?? see my picture for detail.

Use Gtk::STATE_PRELIGHT.

IIRC, there's no guarantee that this will work: it will depend on the
GTK theme the user has configured.  (Pixmap themes, for example, will
definitely ignore this - the progress bar is simply an composite of
bitmaps).

If having a particular colour for the bar is really essential, it
would be safer to draw your own using cairo.

HTH,

Geoff.

You can also enforce the theme for that widget

Hi all, I've just joined the list.

Try calling progress.modify_bg with STATE_PRELIGHT instead of 
STATE_NORMAL.

thank you! STATE_PRELIGHT is work!! and I want to know what's different 
of STATE_PRELIGHT and STATE_NORMAL??

There's API documentation for that.
