Re: Autoresizable NSTextField (2)

Hi,
I did what you say (I hope) but, the fieldEditor already adjusts its frame
size and bounds size automatically. I have seen this putting two NSLog here
below. Anyway, I tried to set the size by myself and redisplay it but the
problem is still there. I cannot see the new text.

    NSText *fE = [[self window] fieldEditor:NO forObject:self];
    if(fE != nil){
        NSLog(@"fEd FrameSize %.2f, %.2f",
        [fE frame].size.width, [fE frame].size.height);
        NSLog(@"fEd BoundsSize %.2f, %.2f",
        [fE bounds].size.width, [fE bounds].size.height);
        [fE setFrameSize:NSMakeSize(strWidth, [fE frame].size.height)];
        [fE setNeedsDisplay:YES];
    }


The good thing I didn't mention earlier is that when I close the editing
with [[self window] endEditingFor:self]; I can see the text properly.


Best Regards
