To reproduce, change the example page.html and wrap the entire contents of the body in the following tags:

<div style="height:500px; width:700px; overflow:auto;">

man page here

</div>

You will see that it is barely possible to go back/forward by swiping to the left/right when the mouse is in the content area even though there is no horizontal scroll bar.

It seems like the scrollWheel callback in DHSwipeClipView is not called often enough in this case.

SwipableWebView generates the following error message in the log:
*** WARNING: Method convertPointToBase: in class NSView is deprecated on 10.7 and later. It should not be used in new applications.

Btw. NSLeftMouseDown is deprecated in 10.12.

I recommend the usage of the new WKWebView technology which provides gesture functions in the IB.

Hi,

The bug I was having was that the indicators that appear when you swipe were displaying behind certain DOM elements within my web view (I heavily use zIndex CSS properties on my elements).

In order to fix this problem I modified - (void)launchDrawTimer of DHSwipeClipView.m to the following:

- (void)launchDrawTimer
{
    // a timer is needed because events are queued and processing and drawing
    // takes longer than they are delivered, so the queue fills up
    if(!drawTimer || ![drawTimer isValid])
    {

        self.drawTimer = [NSTimer scheduledTimerWithTimeInterval:1.0f/25 target:webView.swipeIndicator selector:@selector(display) userInfo:nil repeats:NO];

        // keep indicators at top (I added this)
        NSView *v = webView.swipeIndicator.superview;
        [webView.swipeIndicator removeFromSuperview];
        [v addSubview: webView.swipeIndicator];


    }
}

Did I miss something? Or should I be fine doing this.

I have the swiping enabled for three fingers,
System Preferences > Trackpad > More Gestures > Swipe Between pages

therefore, it won't work with either two or three fingers...
