Not entirely sure what you're trying to describe here. It almost
sounds like you just want to embed your view in an NSScrollView.
No. I want something like a one row NSMatrix. But the cells should
have different sizes. Like a row in an NSTableView.
Because there is no such NSControl (to my knowledge) I have to roll my
own.
Here is a pseudo-example of
- (void)mouseDown:(NSEvent *)anEvent
{
NSPoint aClickLocation = [self convertPoint:[anEvent
locationInWindow] fromView:nil];
NSCell *aCell = [self cellAt:aClickLocation.x];
NSRect aCellFrame = [self frameOfCell:Cell];
if([aCell trackMouse:anEvent inRect:aCellFrame ofView:self
untilMouseUp:NO])
{
// mouseDragged & mouseUp are handled by trackMouse:!
NSText *anEditorView = [[self window] fieldEditor:YES
forObject:nil];
switch ([anEvent clickCount])
{
case 1:
NSInteger aLength = [[selectedCell content]
length];
[aCell selectWithFrame:aCellFrame inView:self editor:anEditorView
delegate:self start:0 length:aLength];
break;
case 2:
[self setEditedCell:selectedCell];
[aCell editWithFrame:aCellFrame inView:self editor:anEditorView
delegate:self event:anEvent];
break;
default:
break;
}
}
}
I think my use of trackMouse: is wrong.
And I need a working method to get the result back.
This looks too twisted to be right:
- (void)textDidEndEditing:(NSNotification *)aNotification
{
NSTextView *aTextView = [aNotification object];
[editedCell setContent:[[[aTextView textStorage] copy] autorelease]];
[self setEditedCell:nil];
if([[self window] firstResponder] == aTextView)
[[self window] makeFirstResponder:self];
[aTextView removeFromSuperview];
}
So if anybody could slip me some code under the table to get this
right (read: in the supposed way) I would be grateful.
atze
ps. my mouseDown: first checks if the user clicked at a point where
two cells touch to be able to resize them.
