set_tooltip_column

Description:

[ Version ( since = "2.12" ) ]
public void set_tooltip_column (int column)

If you only plan to have simple (text-only) tooltips on full rows, you can use this function to have TreeView handle these automatically for you.

column should be set to the column in this’s model containing the tooltip texts, or -1 to disable this feature.

When enabled, has_tooltip will be set to true and this will connect a query_tooltip signal handler.

Note that the signal handler sets the text with set_markup, so &, <, etc have to be escaped in the text.

this	a TreeView
column	an integer, which is a valid column number for this’s model
