View.setIndentWidth

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 propertyView:tab-width property will be used.

The propertyView:indent-width interacts with the propertyView:insert-spaces-instead-of-tabs property and propertyView:tab-width. An example will be clearer:

If the propertyView:indent-width is 4 and propertyView:tab-width is 8 and propertyView: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 propertyView:tab-width is 8). On the other hand, if propertyView: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 gtk.text_buffer.TextBuffer.

The test-widget program (available in the GtkSourceView repository) may be useful to better understand the indentation settings (enable the space drawing!).
