Virtual Method
GtkTextViewdraw_layer
Declaration [src]
void
draw_layer (
GtkTextView* text_view,
GtkTextViewLayer layer,
cairo_t* cr
)
Description [src]
The draw_layer vfunc is called before and after the text
view is drawing its own text. Applications can override this vfunc
in a subclass to draw customized content underneath or above the
text. In the GTK_TEXT_VIEW_LAYER_BELOW_TEXT and GTK_TEXT_VIEW_LAYER_ABOVE_TEXT
the drawing is done in the buffer coordinate space, but the older (deprecated)
layers GTK_TEXT_VIEW_LAYER_BELOW and GTK_TEXT_VIEW_LAYER_ABOVE work in viewport
coordinates, which makes them unnecessarily hard to use. Since: 3.14.
