The documentation for setDoubleAction on a NSTableView states:
If the double-clicked cell is editable, this message isn’t sent
and the cell is edited instead.
However, the behavior I am seeing is that although my double-
clicked cell is editable (tableView:shouldEditTableColumn:row:
does return YES), the selector I passed to setDoubleAction is
called when I double click on the cell.
I can only edit the cell if I first click on the cell, pause for
about 1 second, and click again.
The fact that a double-click on an editable cell doesn't start an
edit when doubleAction has been assigned looks like a bug to me or
the documentation is wrong or I have misinterpreted something.
Anyone care to comment?
Yes, if I don't assign something to doubleAction and double click
the cell, I can edit.
From the Leopard developer release notes:
"NSTableView/NSOutlineView - Single click to editNSTableView and
NSOutlineView now behave like Finder and allow a single click to
put it into edit mode. This is done by calling -
hitTestForEvent:inRect:ofView: and checking if the cell returns
NSCellHitEditableTextArea. This allows you to set a doubleAction
and perform some different task when the doubleAction is invoked
(for instance, Finder opens files on a double click, and edits via
a single click). If the doubleAction is not set, editing is still
allowed via a double click."
Thanks.
So, it doesn't seem possible to, for example, avoid have the
doubleAction invoked if -hitTestForEvent:inRect:ofView: returns
NSCellHitEditableTextArea.
I would still like the edit to start if the user double-clicks on
the editable part of the cell, but the doubleAction invoked if they
do not.
I have a cell consisting of an image and some text. This cell is a
subclass of NSTextFieldCell.
Actually, what appears to work well is:
- (void) handleDoubleClickOnListView:(id)sender
{
NSEvent *currentEvent = [NSApp currentEvent];
NSInteger column = [resourcesList clickedColumn];
NSInteger row = [resourcesList clickedRow];
MyCellClass *theCell = (MyCellClass*)[resourcesList
preparedCellAtColumn:column row:row];
NSRect cellFrame = [resourcesList
frameOfCellAtColumn:column row:row];
NSUInteger hitTestResult = [theCell
hitTestForEvent:currentEvent inRect:cellFrame ofView:resourcesList];
if ( ( hitTestResult & NSCellHitEditableTextArea ) ==
NSCellHitEditableTextArea ) {
if ( [self tableView:resourcesList shouldEditTableColumn:
[[resourcesList tableColumns] objectAtIndex:column] row:row] ) {
[resourcesList editColumn:column row:row
withEvent:currentEvent select:YES];
}
}
else if ( ( hitTestResult & NSCellHitContentArea ) ==
NSCellHitContentArea ) {
}
}
Basically, I just have the double click method start the edit if needed.
