Wt

So where did you exactly use "setStyleClass" for your WContainerWidget and others. Maybe some code...

And i guess you can try the "scrolled()" event.(i.e. setStyleClass when you scroll)

Sorry for not getting back sooner.

The setStyleClass was used almost immediately after initializing each object. I no longer have a code sample pertaining to the exact issue as I coded around it, but the code looked something like the following:

using namespace Wt;

//Create children widgets...

WContainerWidget *conWid = new WContainerWidget();

conWid->decorationStyle().setBackgroundColor(col);

conWid->addWidget(children widgets);

WScrollArea *scrAre = new WScrollArea();

//Scroll area not using any decoration style

scrAre->setWidget(conWid);

WDialog dia("");

(dia.contents())->decorationStyle().setBackgroundColor(black);

(dia.contents())->addWidget(scrAre);

if(dia.exec())

{

//Do something

}

Since the WContainerWidget is at the topmost position (regarding z-order), it's background color should only be visible.
