Complex button contents

[spraff]

Hello. I'm trying to subclass QPushButton to contain arbitrary contents. My first attempt looks a bit like this:


ComplexButton::ComplexButton (QWidget *parent) : QPushButton(Parent) {

QVBoxLayout l = new QVBoxLayout();
l->addWidget(new Foo(this));
l->addWidget(new Bar(this));
l->addWidget(new Baz(this));
setLayout(l);

}

Unfortunately the button is a minimal size and the contents are squashed. I tried putting the QVBoxLayout in a generic QWidget and adding the line

setMinimumSize(generic->sizeHint())
Which at least made the button big enough for the contents.

But that still isn't what I want! :o

I want the buttons to expand their width to fill their parent, causing the parent to widen if necessary. This would happen automatically if I hadn't subclassed QPushButton but merely put a long string in it. I can't recreate that behaviour for love nor money. I've been playing around with the size policy but that hasn't helped and I don't readlly understand it. I imagine the trick is with QPushButton's default layout which I'm replacing, but calling layout() returns a null pointer, and now I'm thoroughly confused.

To sum up: I want a subclass of QPushButton with an arbitrary widget as contents and a space-filling width behaviour.

Clue, please? Cheers.

have you tried calling adjustSize on the button?
(Might be of course that QPushButton did not expect to be subclassed in this way.)

and does size policy work?

I've tried guessing some sizePolicy code, nothing worked.
