Your problem is unrelated to the NSScroller problem I'm experiencing. However,
looking at my code I'm not doing anything special when I create my NSScrollers
to make them horizontal or vertical other than giving them the correctly
oriented frame rect. For example if the frame rect is wider than it is high
then I get a horizontal scroller. I'm not sure that helps, but it might pay to
check the your frame rects are correct.
Here's a snippet of my creation code. As you can see it's pretty
straightforward:
m_scroller = [[NSScroller alloc] initWithFrame:boundsRect];
m_nativeControl = m_scroller;
if ( m_scroller != nil )
{
SetMinValue( inParams.minValue );
SetMaxValue( inParams.maxValue );
SetValue( inParams.initialValue );
[m_scroller setEnabled:YES];
if ( inParams.smallVariant == uctrue )
{
[m_scroller setControlSize:NSSmallControlSize];
}
[m_nativeControl setAutoresizingMask:NSViewMinYMargin];
[[macWindow contentView] addSubview:m_scroller];
}
