I'm building an app using App Designer, and I have encountered a problem.

1) I would like to assign the same uicontextmenu to several uitreenodes and have the MenuSelectedFcn respond to the respective node's NodeData. I tried to make it work via the Tree.SelectedNodes property, however, a node is selected via leftclicking, and I end up passing the different node's NodeData, or make the user leftclick the node before rightclicking for the correct context menu.

Is there a way of selecting a node using rightclick, or alternatively, getting the handle of the node leftclicked?

2) Moreover, I would like to acieve a similar result with uitable:

when I leftclick a certain cell, I would like the contextmenu to respont to the row of the cell (specifically, to the uitable's UserData in the same row as the cell).

Best Regards,

Udi
