get_tooltip_context
Description:
public bool get_tooltip_context (ref int x, ref int y, bool keyboard_tip, out unowned TreeModel? model, out TreePath path, out TreeIter iter)
This function is supposed to be used in a query_tooltip signal handler for TreeView.
The x, y and keyboard_tip values which are received in the signal handler, should be passed to this
function without modification.
The return value indicates whether there is a tree view row at the given coordinates (true) or not (
false) for mouse tooltips. For keyboard tooltips the row returned will be the cursor row. When
true, then any of model, path and iter which have been provided will be
set to point to that row and the corresponding model. x and y will always be converted to be relative to
this’s bin_window if keyboard_tooltip is false.
Parameters:
| this |
a TreeView |
| x |
the x coordinate (relative to widget coordinates) |
| y |
the y coordinate (relative to widget coordinates) |
| keyboard_tip |
whether this is a keyboard tooltip or not |
| model |
a pointer to receive a TreeModel or null |
| path |
a pointer to receive a TreePath or null |
| iter |
a pointer to receive a TreeIter or null |
Returns:
|
whether or not the given tooltip context points to a row. |
