Maintain a Square aspect ratio on widget resizing

[DannyL408]

Hello I have a 1920x1080 window with a frame inside that had 10 qlabels. 50x50 size each

I want to be able to resize my 1920x1080 window to anything and still be able to maintain the square ratio

i have tried working with heightforwidth() but i dont think it works on windows+latest versions

did you set a custom size policy with height-for-width enabled?

QSizePolicy p = this->sizePolicy();
p.setHeightForWidth( true );
this->setSizePolicy( p );

yes i did,
i did some print statements to see if heightforwidth was being called and it wasnt

I have an inherited QLabel in the constructor

QSizePolicy qsp(QSizePolicy::Preferred,QSizePolicy::Preferred);
qsp.setHeightForWidth(true);
setSizePolicy(qsp);

QSize custom::sizeHint() const{
qDebug() << "called";
return QSize(25,25);
}
int custom::heightForWidth ( int w ) const{
qDebug() << this->size() << w;
return w;
}

problem is they will just take up all the available space and wont be a perfect square on every resolution

play around with the size policy values. QSizePolicy::Preferred is the most general one and actually lets the layout almost do what it wants.

none of the sizepolicies seem to work to keep the widget a perfect square on every resolution
