Hi to all
When i compiled and i used the function "del_MouseClicked" i received this error:
Instead when i set a breakpoint anywhere in the code and i compiled line per line with "Step In" command the code worked without errors.
How is possible?
What i want is that all id of nodes correspond to line where they are in TableView
