Description

The GtkSourceGutter object represents the left or right gutter of the text view. It is used by GtkSourceView to draw the line numbers and GtkSourceMarks that might be present on a line. By packing additional GtkSourceGutterRenderer objects in the gutter, you can extend the gutter with your own custom drawings.

To get a GtkSourceGutter, use the gtk_source_view_get_gutter() function.

The gutter works very much the same way as cells rendered in a GtkTreeView. The concept is similar, with the exception that the gutter does not have an underlying GtkTreeModel. The builtin line number renderer is at position GTK_SOURCE_VIEW_GUTTER_POSITION_LINES (-30) and the marks renderer is at GTK_SOURCE_VIEW_GUTTER_POSITION_MARKS (-20). The gutter sorts the renderers in ascending order, from left to right. So the marks are displayed on the right of the line numbers.

Functions

gtk_source_gutter_get_view ()

GtkSourceView *
gtk_source_gutter_get_view (GtkSourceGutter *gutter);

Parameters

gutter

a GtkSourceGutter.

Returns

the associated GtkSourceView.

gtk_source_gutter_get_window_type ()

GtkTextWindowType
gtk_source_gutter_get_window_type (GtkSourceGutter *gutter);

Parameters

gutter

a GtkSourceGutter.

Returns

the GtkTextWindowType of gutter .

Since: 3.24

gtk_source_gutter_insert ()

gboolean
gtk_source_gutter_insert (GtkSourceGutter *gutter,
                          GtkSourceGutterRenderer *renderer,
                          gint position);

Insert renderer into the gutter. If renderer is yet unowned then gutter claims its ownership. Otherwise just increases renderer's reference count. renderer cannot be already inserted to another gutter.

Parameters

gutter	a GtkSourceGutter.
renderer	a gutter renderer (must inherit from GtkSourceGutterRenderer).
position	the renderer position.

Returns

TRUE if operation succeeded. Otherwise FALSE.

Since: 3.0

gtk_source_gutter_reorder ()

void
gtk_source_gutter_reorder (GtkSourceGutter *gutter,
                           GtkSourceGutterRenderer *renderer,
                           gint position);

Reorders renderer in gutter to new position .

Parameters

gutter	a GtkSourceGutterRenderer.
renderer	a GtkCellRenderer.
position	the new renderer position.

Since: 2.8

gtk_source_gutter_remove ()

void
gtk_source_gutter_remove (GtkSourceGutter *gutter,
                          GtkSourceGutterRenderer *renderer);

Removes renderer from gutter .

Parameters

gutter	a GtkSourceGutter.
renderer	a GtkSourceGutterRenderer.

Since: 2.8

gtk_source_gutter_queue_draw ()

void
gtk_source_gutter_queue_draw (GtkSourceGutter *gutter);

Invalidates the drawable area of the gutter. You can use this to force a redraw of the gutter if something has changed and needs to be redrawn.

Parameters

gutter

a GtkSourceGutter.

Since: 2.8

gtk_source_gutter_get_renderer_at_pos ()

GtkSourceGutterRenderer *
gtk_source_gutter_get_renderer_at_pos (GtkSourceGutter *gutter,
                                       gint x,
                                       gint y);

Finds the GtkSourceGutterRenderer at (x, y).

Parameters

gutter	A GtkSourceGutter.
x	The x position to get identified.
y	The y position to get identified.

Returns

the renderer at (x, y) or NULL.
