Hey guys,
I'm trying to replace my old cell-based NSTableView system with the new 10.7+
view-based one without using Xcode's Interface Builder for the table view and
column creation.
What I am doing now is creating an NSTableCellView inside NSTableView's
delegate method [-NSTableView tableView:viewForTableColumn:row:]:
- (NSView *)tableView:(NSOutlineView *)aTableView
viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row
{
NSString *identifier = [tableColumn identifier];
NSString *stringValue = [self tableView:aTableView
objectValueForTableColumn:tableColumn row:row];
NSTableCellView *cellView = [aTableView
makeViewWithIdentifier:identifier owner:self];
if (cellView == nil)
{
// Create cell view
cellView = [[[NSTableCellView alloc] initWithFrame:[cellView
frame]] autorelease];
cellView.identifier = identifier;
// Create text field
NSTextField *textField = [[[NSTextField alloc]
initWithFrame:[cellView frame]] autorelease];
[textField setIdentifier:identifier];
[textField setBordered:NO];
[textField setDrawsBackground:NO];
[textField setStringValue: stringValue];
cellView.textField = textField;
[cellView addSubview:textField];
return cellView:
}
[cellView.textField stringValue];
return cellView;
}
The problem here is that I don't have any idea where and how to get and set the
frame of the cell. As you can see during the creation of NSTableCellView I'm
basically using an NSZeroRect because [cellView frame] is nil. I subclassed
NSTableCellView and added a red color for the background in order to see if the
NSZeroRect gets automatically updated to the current cell rect - it does work.
But it just doesn't make sense to create a subview of NSTableCellView with a
zero-frame... is there a method inside NSTableCellView I should subclass and
position the NSTextField? Or is it common to get the frame inside
-viewForTableColumn and adjusting the text field there? What's the way Apple
had in mind concerning programmatically creating a view-based NSTableView? I
couldn't find a lot of information on this, the demo video on
developer.apple.com directly uses an NSTextField as the return cell-view but my
view needs to be more complex than that. I am pretty sure I just missed
something very important here. ;-) And my second question is - is it possible
to create a cell view which is bigger than one row, thus it's overlaying other
rows (I'm not customizing my table view to death, I have a good reason for cell
views being positioned over several rows).
Thank you very much in advance!
