add ability to set tooltips for entries in GtkComboBox
Last modified: 2017-03-03 14:45:51 UTC
You should be able to add a ToolTip that corresponds to (and appears when hovered over) each model item in a GtkComboBox, rather than just the widget as a whole. Apparently this is not possible ATM: http://www.daa.com.au/pipermail/pygtk/2009-January/016512.html
I second this. In the OptionMenu tooltips can be added because the entries are menu items. But it has been made obsolescent and there's no replacement in GtkComboBox yet. Neither for horizontal separators which the OptionMenu has by adding an empty menu item.
This seems like a duplicate of #303717.
