*FIXED (Sort of)* JTree Cell Editing ::stopCellEditing does not work

[Andy_Hollywood]

Well sort of fixed, i just placed my model in the editor, called the methods to get the new value, set the value in themodel, then called cancel cell editing, it appears to give the same results but is a bit of a hack to be honest.. if anyone has any other suggestiosn then let me know

Andy...




Hello

I wanted to do some tree cell/node editing, so i wrote my own TreeCellEditor, everything works apart from the stop cell editing, from what i understood, when this was called it would alert my model and call the method, valueForPathHasChanged(Path, newvalue) and this is where i would do all my actuall changes, for some reason this isn't triggering, and my stop cell editing method, when called dosen't seem to remove the editing renderer from the tree, untill i click on another node....

what is it i'm doing wrong? i cycle through my listeners and call stopcellediting, but it dosen't seem to work...
