Bug 38896 – [GTK] Theme does not render when printing

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Alejandro G. Castro]

The theme rendering is using the gdkdrawable from the expose event, when printing there is no expose event rendering, the result is the theme (buttons, combos, etc.) are not printed.

WebCore/platform/gtk/RenderThemeGtk.cpp:
...
     if (!i.context->gdkDrawable())
        return true;
...

We can use GRefPtr for the pixmap, so r- to do that.

It also seems when there's no expose event and printing is disabled we'll create a pixmap just to immediately destroy it, which seems a bit pointless.
