Sets the number of spaces to use for each step of indent when the tab key is
pressed.
If @width is -1, the value of the [property@View:tab-width] property
will be used.
The [property@View:indent-width] interacts with the
[property@View:insert-spaces-instead-of-tabs] property and
[property@View:tab-width]. An example will be clearer:
If the [property@View:indent-width] is 4 and [property@View:tab-width] is 8 and
[property@View:insert-spaces-instead-of-tabs] is %FALSE, then pressing the tab
key at the beginning of a line will insert 4 spaces. So far so good. Pressing
the tab key a second time will remove the 4 spaces and insert a \t character
instead (since [property@View:tab-width] is 8). On the other hand, if
[property@View:insert-spaces-instead-of-tabs] is %TRUE, the second tab key
pressed will insert 4 more spaces for a total of 8 spaces in the
[class@Gtk.TextBuffer].
The test-widget program (available in the GtkSourceView repository) may be
useful to better understand the indentation settings (enable the space
drawing!).
