hi anyone out there, i have more information on this scroll bar bug
if i open more and more text windows the scroll bar (nsscroller) appears on the right or bottom of each one each window has 2 scroll bars, i have verified the 2 sub views, but only one can appear at a time i can't find any graphics clipping problems or something like that i have looked for something that tells the scroll bar to be vertical or horizonta but can't find it, i assume it looks at the width or height & just does that automatically i think i can see a horizontal bar stuck in a little piece of the vertical slot, and a vertical bar stuck in the horizontal slot the slots are correct in size, but the bar hasn't re-jiggered to fit the slot does anyone know what is going on? thanks, bill On Thu, Apr 29, 2010 at 12:08 PM, Bill Appleton < billapple...@dreamfactory.com> wrote: > hi Jo, > > i am also working with NSScroller directly > > i have two types of windows > > in one type, the vertical bar appears and the horizontal bar is missing > > in the other type, the opposite situation occurs > > i am sure they are set to the right bounds, etc. and visible > > have you looked at NSControl > > calcSize and sizeToFit? > > > thx > > bill appleton > > > > > > > > > > On Thu, Apr 29, 2010 at 4:59 AM, Jo Meder <jome...@ihug.co.nz> wrote: > >> Hi, >> >> I'm using NSScrollers directly, e.g. not in an NSScrollView.
