Square custom QWidgets inside QGridLayout inside QScrollArea

[blashyrk]

Hello,
I'm trying to lay out a grid of square custom (subclassed) QWidgets inside a QGridLayout and QScrollArea.

The way I want it to work is choosing the number of QGridLayout columns and creating squares of the correct sizes.

What I've tried doing already is

• Manually laying out/resizing the QWidgets but I feel this is a bit sloppy and I couldn't get it quite right
• Setting QScrollArea::widgetsResized to true which does resize the width correctly, but not the height, see screenshot.

I've tried setting QSizePolicy and overriding QWidget::heightForWidth along with setting QScrollArea::widgetsResized in my custom QWidget-derived class, like so:

CustomWidget::CustomWidget(...) 
{  
  ...

  QSizePolicy policy(QSizePolicy::Preferred, QSizePolicy::Preferred);
  policy.setHeightForWidth(true);

  setSizePolicy(policy);
}

...

int CustomWidget::heightForWidth(int width) const
{
    return width; // square
}

But CustomWidget::heightForWidth is never called.

Any help would be appreciated.
