HIWebView and Tabs Control

Hi all,

I've been a bit of a lurker on this list, but I'm one of the developers for wxWidgets/wxMac, and one of the things I've been working on is a wrapper for WebKit (wxWebKitCtrl). I'm currently working on the Carbon port, and have noticed some problems with WebView being embedded in a Tabs Control. I wanted to know if anyone else is seeing these issues, or if maybe I am doing something wrong.

1) The most serious problem is that the Cocoa WebView does not have the same origin as the HIWebView, but *only* when embedded in the Tabs control. To reproduce this, add HIWebView as a subview of a tabs control, and then position the tabs control at a position other than 0, 0 relative to its parent. The Cocoa WebView will, it seems, position itself relative to the Tabs control's parent (or possibly relative to the top level window), rather than relative to the Tabs control, while the HIWebView will correctly position itself relative to the Tabs Control. Thus, events like mouseovers will happen in the correct location, while the actual display of the control will be at the top left corner of the Tabs control's parent.

I have been able to workaround this by checking for a Tabs control, and if found, calculating the position relative to the parent all the way up until the tabs control. This does place the WebView in the correct position (usually, there are some corner cases I haven't found yet). Any ideas if there is any easy way to make this work?

2) Visibility issues. I have found that the WebView tends to make it self visible periodically in a Tabs control even when it is not the active tab. Reading some messages on this list, I got the impression this is because in Cocoa, the proper behavior is to only ever have one subview for the Tabs control, and that's the active view. Tab switching is basically done by adding and removing subviews from the Tabs control. Is this an appropriate solution for Carbon as well? I see that wxMac does not do things this way currently, but I'm somewhat new to Mac development so I wasn't quite sure if changing the behavior will have adverse effects on Carbon/OS X.

Overall, the process of embedding WebView has been a smooth one, but if I could get some guidance on these "gotchas" I would really appreciate it!

Thanks,

Kevin
