Detailed Description

ToolBar class which displays a path like a set of pop-up menus.

Library: ilvadvgdt

This toolbar class displays a path as a set of pop-up menus. Each directory of the path becomes a button of the toolbar. Between each button, a pop-up menu displays the directory list from the same level as the path associated with the button. When the user clicks a button or chooses a menu entry, a callback is invoked with the path chosen by the user. Note: This class has been designed for the IlvFileChooser dialog. It cannot be saved into an Ilv file.
