Reuse a Qwidget with a QStackWidget

[ucomesdag]

Hi,

I'm looking for away to reuse a QWidget and add it multiple times to a QStackWidget.

I need something close to this

QGridLayout *myLayout = new QGridLayout;
 
QWidget *tmpWidget = new QWidget;
tmpWidget->setLayout(myLayout);
 
QStackWidget *myStackWidget = new QStackWidget;
 
for(int i=0;i<10;++i)
{
    myStackWidget->insertWidget(i, tmpWidget);
};

QGridLayout *myLayout = new QGridLayout;

QWidget *tmpWidget = new QWidget;
tmpWidget->setLayout(myLayout);

QStackWidget *myStackWidget = new QStackWidget;
  
for(int i=0;i<10;++i)
{
    myStackWidget->insertWidget(i, tmpWidget);
};

To copy to clipboard, switch view to plain text mode 

Any help is appreciated, thanks.

This is not possible... A widget cannot have more than one parent ( the stacked widgets page reparents the widget bas soon as you add it ).


Do you need exactly the same instance of the widget in all pages? Then when you change the stacked widget page, just remove the tmpWidget from the previous position and add it to the current position. Not very nice, but...

Ultimately, create 10 widgets, and that's it. If you want the changes from one widget to reflect in the others, just synchronize them with signals/slots.

if you need to show the same data on various views, you might want to design it with the model/view approach.

That or you could make that widget contain static variables (so they all have the same data) and create a new instance for each page of your stacked widget. That should also free you up to make some parts of your widget different on each page.

Is there else a way to duplicate the widget?

Found the answer myself: No...
