I have horizontal layout: on the left - WTreeView, on the right - WPaintedWidget which content depends on current scroll value. In other words I need to draw lines opposite tree nodes.

However I write this crazy js solution and it works:

wApp->declareJavaScriptFunction("SuperScroll",

"function() "

"{ console.log( \"Super scroll!\"); "

"var top = this.scrollTop;"

"console.log(\"this top:\", top);"

"console.log(\"this id:\", this.id)}");

treeView~~doJavaScript("var firstChild = " + treeView~~>jsRef() + ".children[0];"

"console.log(\"first child: \", firstChild.id);"

"var tree = firstChild.children[1];"

"console.log(\"tree: \", tree.id);"

"tree.addEventListener('scroll', " + wApp->javaScriptClass() + ".SuperScroll, false);");

I looked html dom hierarchy of WTreeView and find that second child of first child of WTreeView is proper scroll area, but I am a bit afraid of version problem if u change some code in WTreeView.

Hey,

That sounds like a sensible use-case, indeed. I guess we the super-crazy hack would be simplified if we provide access to the widget that is the virtual scroll container --- that's probably a safe thing to do.

Thank you, Koen, that would be nice with usage example.
