toolTips
Whether to display text labels as tooltips if they are too long to display fully in the tree view area as the mouse passes over them.
Property of
TreeView
Description
When toolTips is true, tree item text labels are displayed as tooltips if necessary as the mouse passes over them. The tooltip displays directly over the obscured text label, in the exact position where the text label should appear.
In general, this allows the user to see the entire text label without having to scroll the tree view back and forth horizontally. However, some portion of the tree item must be visible; if the tree item is completely outside the tree view area, the item will not appear simply by pointing the mouse where the item would be (because the mouse is outside the bounds of the TreeView object).
