Re: My own listbox

You should be able to get close by using a different type of object for the Cells.

That's a much nicer way of doing it.

The problem is that my control will work like listbox, but don't
exactly. Actually I need to draw every row myself. And these rows will
have some padding and many graphics stuff inside. And they will have
adjustable height... And so on.

I don't think that it is possible to do this with standard controls. Am I wrong? On Sat, Aug 2, 2008 at 1:33 PM, Boris Remizov <[EMAIL PROTECTED]> wrote:

Hello,
In windows there is a control called "Listbox". It looks like grid

Example is here:
http://www.java2s.com/Tutorial/VBImages/ListBoxSelectionEventAddValue.PNG

I need to create control that works similar way. It will not be

and an optional scrollbar. As a "good" cocoa programmer I derived
NSControl and implemented -drawRect to draw my own rows. Then I put
this control to the window in Interface Builder and embed it into
NSScrollView. Here the problem starts. How can I tell NSScrollView
what size does my control have? I tried to implement -bounds and
-frame methods, but scroller became crazy. I tried this code:

- (NSRect) frame
{
 NSRect rc = [super frame];
 rc.size.height = number_of_rows * height_of_row;
 return rc;
}

- (NSRect) bounds {.. the same..}


it - it scrolls my control to the wrong direction. I tried to play
with -isFlipped - no success.

So I need some similar source to take a look for what I missed. Does
anybody have one?
Thank you.

with single column without header. Several rows and maybe a scrollbar. actually a listbox, but it will work the same way: few objects - rows NSScrollView shows scrollbar with correct proportions, but then I drag
