[Qt-interest] QVBOxLayout problem with QSCrollArea and QWidget

[sarvesh saran]

Hi,

is showcasepage being initialized after you pass it to CHeadWidget and
PageForGraph?

Also, when you use a layout, you do not need to pass a parent when
constructing the child widgets. The layout will automatically re-parent the
widgets so that they are children of the widget on which the layout is
installed.

thanks,
Sarvesh
