[Qt-interest] QStackedWidget Problem

[Malyushytsky, Alex]

Use debugger to find reason the code  is crushing.
If you use binaries you might need to build Qt  yourself, so you can step in.
If you provided minimal compilable example, someone could help you in it.
As is there are too many chances problem is in your code you don't provide.

Hi Syam and all others
By setting
pointerToSomeOtherClass as parent of curPlot its crashing.

Actually my pointerToSomeOtherClass is a QScrollArea

pointerToSomeOtherClass->setWidget(curPlot);

But its crashing .. any other hints highly appreciated.


Kind Regards,

Dear Friends

class COptWidget : public QWiget
{
                Q_OBJECT
public:
                COptWidget(SomeOtherClass *parent=0);
                ~COptWidget();
};

COptWidget *plotopt = new COptWidget(pointerToSomeOtherClass);
QStackedWidget  *curPlot =  new QStackedWidget;
curPlot->addWidget(plotopt);
curPlot->setCurrentWidget(plotopt);


But with this I am not able to see the plot what am I missing here. Application crashed at curPlot->addWidget(plotopt);

What/where is the parent widget for the stacked widget? It looks like you need to pass 'pointerToSomeOtherClass' as the parent of the stacked widget instead of your plot widget.

regards,

Syam
