RE: [PHP-GTK] RE: Changing color/style on ascrollbarinaGtkScrolledWindow

Madeleine, Steph, It's true that Steph's basic, stand-alone example worked just as she said on my Win2k box. However, I did comment out all usages of GtkStyle, style->bg, and set_style in my 4k plus line app, and the color changes to scrollbars and column headers using the same code snippet were never realized. It is similar to what Madeleine is saying; nothing blew up, no errors thrown, but no changes either. It goes without saying that I'm no expert with php-gtk, but something seems amiss. For example, changing color/style on GtkLabel and GtkButton widgets went exactly as expected, even towards the end of my long-ish script. Now if this is compared with our ambiguous results for GtkScrolledWindow (and, in my case GtkClist column headers, too), then there is an inconsistency that is perplexing. But, again, I was able to propagate color changes from GtkWindow on down with: $window = &new GtkWindow(); $appStyle = gtk::widget_get_default_style(); $basicBackGroundColor = &new GdkColor('#E0EEE0'); $mouseOverColor = &new GdkColor('#CFDEF1'); $appStyle->bg[GTK_STATE_NORMAL] = $basicBackGroundColor; $appStyle->bg[GTK_STATE_PRELIGHT] = $mouseOverColor; $window->set_style($appStyle); then re-style buttons and text as before. There certainly seems to be some selective masking, or selective disconnection style-wise, going on. Just my 2 cents. dave > Sorry, Dave and I went off-list there.
