Hi, I want to set the uimenu objects in app.contextmenu dynamically. just like following code:
function ContextMenuOpening(app, event)
app.ContextMenu = cmHandle;
uimenu(cmHandle,'Label','Wider');
uimenu(cmHandle,'Label','Inspect');
end
end
The problem is that the app.contextMenu will save all added uimenu in every funtion calling and never drop repeated items. I need a answer to clear all children in app.ContextMenu.
Thanks a lot!

"I need a answer to clear all children in app.ContextMenu."
delete(app.ContextMenu.Children)

I solved the menus getting repeated with every click by using an "if" statement to check the children (menus) are already there or not,
if isempty(app.ContextMenu.Children)
text = "your menu text";
m1 = uimenu(app.ContextMenu,'Text',text);
end
