Gtk.Widget.prototype.draw
function draw(cr:cairo.Context):void { // Gjs wrapper for gtk_widget_draw() }
Draws widget to cr. The top left corner of the widget will be drawn to the currently set origin point of cr.
You should pass a cairo context as cr argument that is in an original state. Otherwise the resulting drawing is undefined. For example changing the operator using cairo_set_operator() or the line width using cairo_set_line_width() might have unwanted side effects. You may however change the context's transform matrix - like with cairo_scale(), cairo_translate() or cairo_set_matrix() and clip region with cairo_clip() prior to calling this function. Also, it is fine to modify the context with cairo_save() and cairo_push_group() prior to calling this function.
