Widget that displays a map for a specific View.

GtkSourceMap is a widget that maps the content of a View into a smaller view so the user can have a quick overview of the whole document.

This works by connecting a View to to the GtkSourceMap using the view property or set_view.

GtkSourceMap is a View object. This means that you can add a GutterRenderer to a gutter in the same way you would for a View. One example might be a GutterRenderer that shows which lines have changed in the document.

Additionally, it is desirable to match the font of the GtkSourceMap and the View used for editing. Therefore, font_desc should be used to set the target font. You will need to adjust this to the desired font size for the map. A 1pt font generally seems to be an appropriate font size. “Monospace 1” is the default. See set_size for how to alter the size of an existing FontDescription.

When FontConfig is available, GtkSourceMap will try to use a bundled “block” font to make the map more legible.
