I have a need for windows that maintain a set aspect ratio, so I implemented
heightForWidth(). Since I'm still exploring, I made it very simple (this
function is called by a wrapper class that actually implements
heightForWidth()):
int grafRec::doHeightForWidth(int w)
{
return w/2;
}
I set a size policy:
QSizePolicy policy(QSizePolicy::Preferred,
QSizePolicy::Preferred);
policy.setHeightForWidth(true);
content->setSizePolicy(policy);
The object called "content" is a subclass of QWidget and it is embedded in a
cell of a QGridLayout. There are no other cells in the layout occupied. The
layout and managed content widget are embedded in a top-level widget.
This actually works up to a point. As I make the window get wider, it also gets
taller in proportion. But evidently Qt is enforcing a height that is *at least*
half the width, where I really need a height that is *exactly* half the width.
Is this working as expected, that the height returned by heightForWidth() is
really a minimum height? If that is so, is there a way to achieve what I really
want?
Thank you all!
