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 tab_width property will be
used.
The indent_width interacts with the
insert_spaces_instead_of_tabs property and
tab_width. An example will be clearer: if the
indent_width is 4 and
tab_width is 8 and
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 tab_width is 8). On the other
hand, if 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 TextBuffer.
The test-widget program (available in the GtkSourceView repository) may be useful to better understand the indentation settings (enable the space drawing!).
