Return custom widget from QStackedWidget
-
I am trying to access a widget that inherits QWidget which is added to my QStackedWidget.
I have for example a class "PageTwo" that inherits QWidget. This "PageTwo" is added to my QStackedWidget. I call get function in a unrelated class that return the QStackedWidget object, which I then use roughly "Object->getStackedWidget()->widget(PageTwo)" but it complains that it cannot convert from "QWidget *" to "PageTwo".
Am I doing this wrong? I need to be able to access the stackedwidget from all pages so that I can call a function on each page just before going to it.

From the description it looks like are trying to assign base class pointer to derived class pointer. Hence hitting the issue

Hi
You can access "Pages" with
http://doc.qt.io/qt-5/qstackedwidget.html#widget
it returns a base QWidget pointer so you have to cast it to your type.PageTwo *p2=qobject_cast<PageTwo *>( StackedWidget ->widget(0) );
if(p2) { // always check if cast worked. else it be null
use the custom page.
