Subviews are always drawn after the parent (for obvious reasons if you think about it), so if I correctly understand the point you're trying to make, there won't be a problem.

That means the linked-to code may not be quite complete -- it may also be necessary to ensure that the custom corner view draws above and/or after the scroll view, or else it may get painted over. I think that's what went wrong when the OP tried to follow this code pattern originally, although I don't think it's been confirmed. (Maybe the OP's recent silence means that it's all working now.) I did learn something marginally interesting from looking at the NSScrollView behavior in IB. If you set the background color to something other than white, it draws the clip view background in the specified color, but still draws the corner in white. I'm hopeful that piece of information may come in useful one of these years. :) ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

You've created a view that fills your entire scrollview, just to draw some background colour in the corner. What I meant was to create a small view that is just the size of that small corner and use the - tile method to position it in the corner where you want it. This is what the sample code I pointed to is doing, albeit positioning a placard view in a different place. Also, you are drawing the other's view's "content" in your scroll view. Instead, that view should be drawing its own content. This means you have to subclass NSView to make the corner view and implement its - drawRect method to draw whatever it is you want it to do. None of these things are difficult. I'm afraid your solution is incorrect. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

If it covers the lower right corner and your window is resizable, the white could be coming from the window's grow box view, not from your scroll view or table view. There seems to be some extra interaction where a table view leaves room for the grow box under a vertical scroller (if no horizontal scroller is there), and sets it to opaque as well.

Hi, Graham,
I think I finally got what you said. I referred your linked sample, and
implemented my source as follows.(I enclose my source for anyone who has
same problem with many thanks to this list.) I also needed to add some code
to drawRect to draw my custom view correctly.
If you find any problem from my source, please let me know.
#import "BSScrollView.h"
@implementation BSScrollView
// Prepare a view to be a background of scrollers. This view will cover all
area of scrollView.
- (void) _setScrollerBackgroundView:(NSView *) view{
[view retain];
[_scrollerBackgroundView release];
_scrollerBackgroundView = view;
[self addSubview:_scrollerBackgroundView];
}
- (NSView *) scrollerBackgroundView {
return _scrollerBackgroundView;
}
- (void)tile {
[super tile];
if (![self scrollerBackgroundView])
{
// Place a view that cover all area of scroll view.
NSRect tempRect = NSMakeRect(0.0, 0.0, [self bounds].size.width, [self
bounds].size.height);
NSView *tempView = [NSView allocWithZone:[self zone]];
[tempView initWithFrame:tempRect];
[self _setScrollerBackgroundView:tempView];
}
}
- (void)drawRect:(NSRect)rect {
[super drawRect:rect];
// draw background color for scroll view. This color fills areas under knob
slots and right bottom area of scroll view.
[[NSColor blackColor]set];
NSRectFill([_scrollerBackgroundView frame]);
}
- (void) dealloc {
[_scrollerBackgroundView release];
[super dealloc];
}
@end

Did you try [scrollView setDrawsBackground: NO]? The area you want to draw is normally filled with white by the scroll view, and that's probably drawing over the top of your custom view. If you tell the scroll view not to draw its background, your view should show through. If it still doesn't show up, you'll need to actually debug your code. Is your view in the right place in the window? If so, is it hidden? If not, is it being drawn underneath something else? You'll need to look for an answer, instead of just coming back to this list and complaining that your code doesn't work. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
