Function

Gtkpaint_expander

Declaration [src]

void
gtk_paint_expander (
  GtkStyle* style,
  cairo_t* cr,
  GtkStateType state_type,
  GtkWidget* widget,
  const gchar* detail,
  gint x,
  gint y,
  GtkExpanderStyle expander_style
)

Description [src]

Draws an expander as used in GtkTreeView. x and y specify the center the expander. The size of the expander is determined by the “expander-size” style property of widget. (If widget is not specified or doesn’t have an “expander-size” property, an unspecified default size will be used, since the caller doesn’t have sufficient information to position the expander, this is likely not useful.) The expander is expander_size pixels tall in the collapsed position and expander_size pixels wide in the expanded position.

Deprecated since:	3.0
Use `gtk_render_expander()` instead.
