Hallo Jürgen,

you only have to overwrite the "abstract" Method
MouseButtonDoubleClick() of the TreeView-Class.

For example:

Method MouseButtonDoubleClick(oMouseEvent) class MyTreeView
// Write your code here

return nil

Hi Stefan,

I have done this! But I create 2 events: a MouseButtonDoubleClick and
aTreevieSelectionChange event. But I can only evaluate the
TreviewSelectionChange event.

There will always be two events when you select an item by
doubleclick: the TreeViewSelectionChanged is a notification sent by
the control to the owner when a new item is selected and the
MouseButtonDoubleClick is generated by the control itself when a
doubleclick occurs.

> I can only evaluate the TreeViewSelectionChanged event
I can not understand what you mean. Why can you evaluate only the
TreeViewSelectionChanged event? Put the code in a method and call the
method on both events!
