This method is called by the library when the user requests popup menu (on Windows and Unix platforms, this is when the user right-clicks the icon).
This method is similar to wxWindow::Destroy and can be used to schedule the task bar icon object for the delayed destruction: it will be deleted during the next event loop iteration, which allows the task bar icon to process any pending events for it before being destroyed.
Returns true if SetIcon() was called with no subsequent RemoveIcon().
Returns true if the object initialized successfully.
Pops up a menu at the current mouse position.
Removes the icon previously set with SetIcon().
Sets the icon, and optional tooltip text.
