So I have a project that has some content being displayed in a WebView and I want to stick above that. I want the header to scroll with the WebView content. Now, WebView generally wants to do it's own scroll handling but you can tell it not to using:
[[webView mainFrame] setAllowsScrolling:NO];
which successfully makes the WebView's scroll bars not appear. However, despite the fact that it's embedded in an NSScrollView, the NSScrollView's scroll bars never activate. I can only conclude that the WebView needs to be told to resize, but I can't figure out how to do that. I have tried the following:
NSRect webViewBounds = [webView bounds];
[webView setFrameSize:webViewBounds.size];
but that doesn't appear to work either.
Any suggestions?
Alternative solution: What about expressing the header in HTML/CSS/JavaScript, and putting the real content in an iframe? You can traverse the frame hierarchy to find the WebFrame object for that frame, and use the DOM (perhaps wrapped by an object of your own) to control the header.
