You can get an iterator corresponding to a textmark by using the gtk.TextBuffer.get_iter_at_mark() method. Unlike iterators, textmarks remain valid across buffer modifications (e.g. when text is inserted or deleted). When text containing a textmark is deleted, the textmark remains in the position originally occupied by the deleted text. When text is inserted at a textmark, a textmark with left gravity will be moved to the beginning of the newly-inserted text, and a textmark with right gravity will be moved to the end. Textmarks optionally have names that can be used to avoid passing the gtk.TextMark object around. Textmarks are typically created using the gtk.TextBuffer.create_mark() method. A gtk.TextBuffer has two built-in gtk.TextMark objects named: insert and selection_bound which refer to the insertion point and the boundary of the selection (these may refer to the same location). set_visible setting setting : if True the textmark is visible The set_visible() method sets the visibility of the textmark to the value specified by setting. If setting is True the textmark will be visible as a vertical bar. The insertion point is normally visible but most textmarks are not visible by default. The text widget uses a visible textmark to indicate where a drop will occur when dragging-and-dropping text. get_visible Returns : True if the textmark is visible The get_visible() method returns True if the textmark is visible (i.e. a vertical bar is displayed for it) get_name Returns : the textmark name or None The get_name() method returns the textmark name or None if the textmark is anonymous. get_deleted Returns : True if the textmark is deleted The get_deleted() method returns True if the textmark has been removed from its textbuffer with gtk.TextBuffer.delete_mark(). Textmarks can't be used once deleted. get_buffer Returns : the textmark's gtk.TextBuffer The get_buffer() method returns the gtk.TextBuffer object the textmark is located inside, or None if the textmark is deleted. get_left_gravity Returns : True if the textmark has left gravity The get_left_gravity() method returns True if the textmark has left gravity.
