Method

GtkWidgetdraw

Declaration [src]

void
gtk_widget_draw (
  GtkWidget* widget,
  cairo_t* cr
)

Description [src]

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.

Note that special-purpose widgets may contain special code for rendering to the screen and might appear differently on screen and when rendered using gtk_widget_draw().

Available since:3.0

Parameters

cr cairo_t
 

A cairo context to draw to.

 The data is owned by the caller of the function.
