-TreeViewTooltips.py
-
-Provides TreeViewTooltips, a class which presents tooltips for cells,
-columns and rows in a gtk.TreeView.
-
-------------------------------------------------------------
- This file includes a demo. Just execute the file:
-
- python TreeViewTooltips.py
-------------------------------------------------------------
-
-To use, first subclass TreeViewTooltips and implement the get_tooltip()
-method; see below. Then add any number of gtk.TreeVew widgets to a
-TreeViewTooltips instance by calling the add_view() method. Overview
-of the steps:
-
- # 1. subclass TreeViewTooltips
- class MyTooltips(TreeViewTooltips):
-
- # 2. overriding get_tooltip()
- def get_tooltip(...):
- ...
-
- # 3. create an instance
- mytips = MyTooltips()
-
- # 4. Build up your gtk.TreeView.
- myview = gtk.TreeView()
- ...# create columns, set the model, etc.
-
- # 5. Add the view to the tooltips
- mytips.add_view(myview)
-
-How it works: the add_view() method connects the TreeView to the
-"motion-notify" event with the callback set to a private method.
-Whenever the mouse moves across the TreeView the callback will call
-get_tooltip() with the following arguments:
-
- get_tooltip(view, column, path)
-
-where,
-
- view: the gtk.TreeView instance.
- column: the gtk.TreeViewColumn instance that the mouse is
- currently over.
- path: the path to the row that the mouse is currently over.
-
-Based on whether or not column and path are checked for specific
-values, get_tooltip can return tooltips for a cell, column, row or the
-whole view:
-
- Column Checked Path Checked Tooltip For...
- Y Y cell
- Y N column
- N Y row
- N N view
-
-get_tooltip() should return None if no tooltip should be displayed.
-Otherwise the return value will be coerced to a string (with the str()
-builtin) and stripped; if non-empty, the result will be displayed as
-the tooltip. By default, the tooltip popup window will be displayed
-centered and just below the pointer and will remain shown until the
-pointer leaves the cell (or column, or row, or view, depending on how
-get_tooltip() is implemented).
