objective c - Disable scrolling in NSTableView

Question

Is there a simple way to disable scrolling of an NSTableView.

It seems there isn't any property on [myTableView enclosingScrollView] or [[myTableView enclosingScrollView] contentView] to disable it.

Answer 1

This works for me: subclass NSScrollView, setup and override via:

- (id)initWithFrame:(NSRect)frameRect; // in case you generate the scroll view manually
- (void)awakeFromNib; // in case you generate the scroll view via IB
- (void)hideScrollers; // programmatically hide the scrollers, so it works all the time
- (void)scrollWheel:(NSEvent *)theEvent; // disable scrolling

@interface MyScrollView : NSScrollView
@end

#import "MyScrollView.h"

@implementation MyScrollView

- (id)initWithFrame:(NSRect)frameRect
{
    self = [super initWithFrame:frameRect];
    if (self) {
        [self hideScrollers];
    }

    return self;
}

- (void)awakeFromNib
{
    [self hideScrollers];
}

- (void)hideScrollers
{
    // Hide the scrollers. You may want to do this if you're syncing the scrolling
    // this NSScrollView with another one.
    [self setHasHorizontalScroller:NO];
    [self setHasVerticalScroller:NO];
}

- (void)scrollWheel:(NSEvent *)theEvent
{
    // Do nothing: disable scrolling altogether
}

@end

I hope this helps.
