the GTK nsWidget constructor gets a Look and feel object everytime, just to get a single value from it and destroy it. http://lxr.mozilla.org/seamonkey/source/widget/src/gtk/nsWidget.cpp#39

we could do this by creating a style each time, but in order to get the correct colors, this is needed. (saving the overhead from L&F but still creating some overhead). This is required in part because we are using GTK and therefore should support its themes. If we don't do this, then the colors get fubar, and broken. I will look into this in more detail.

Is there any way to be notified when GTK's style info changes? Can we just cache the nsILookAndFeel * for now, and avoid the CreateInterface overhead every time?

I've committed the attached patch.

Pavlov believes that it's safe for the LnF object to cache the GtkStyle * as well, so I've committed again.

sorry for bugzilla spam. trying to get these off my radar

re-verifying this bug.
