I have an NSOutlineView. When I edit a cell in it and hit return, I would like the cell directly below it to go immediately into edit mode.
I thought I would use the controlTextDidEndEditing: delegate method to find out when editing of a cell had finished, and the editColumn:row:withEvent:select: method to put the cell below it into edit mode.
Here's a demo method that I pasted into "appcontroller.m" of the Apple demo code project, "DragNDropOutlineView":
- (void)controlTextDidEndEditing:(NSNotification *)aNotification
{
NSTreeNode* treeNodeJustEdited;
NSInteger indexOfCurrentRow = [outlineView selectedRow];
if (indexOfCurrentRow < 0) //no row selected
return;
treeNodeJustEdited = [outlineView itemAtRow:indexOfCurrentRow];
NSTreeNode* theRootNode = rootTreeNode;
NSInteger numberOfChildren = [[theRootNode mutableChildNodes]count];
NSInteger indexOfLastChild = numberOfChildren - 1;
if (indexOfCurrentRow < indexOfLastChild)
{
[outlineView selectRowIndexes:[NSIndexSet indexSetWithIndex:indexOfCurrentRow+1] byExtendingSelection:NO];
[outlineView editColumn:0 row: indexOfCurrentRow+1 withEvent:nil select:NO];
}
}
For some reason, this does the following:
- Correctly highlights the row below the cell just edited. But then:
- Disables that highlighting, i.e. puts it in light grey
- Makes the cell below the cell just edited, invisible. Clicking twice on that cell returns the table to normal.
What am I missing in order to get this method to perform as desired?
