Hi,
as fast example:
int main(int argc, char **argv)
{
MApplication app(argc, argv);
MApplicationWindow w;
MApplicationPage p;
MLayout * layout = new MLayout(p.centralWidget());
layout->setContentsMargins(0,0,0,0);
MLinearLayoutPolicy *policy = new
MLinearLayoutPolicy(layout,Qt::Vertical);
MButton * button1 = new MButton();
button1->setStyleName("ButtonExample");
button1->setViewType(MButton::iconType);
button1->setIconID("icon-l-backup");
policy->addItem(button1,Qt::AlignCenter);
layout->setLandscapePolicy(policy);
p.appear(&w);
w.show();
return app.exec();
}
And then you placed in the CSS file the following style:
#ButtonExample {
icon-size: 60mm 60mm;
}
It will scale your icon until the mentioned size. I tested and it works
without any problem.
Cheers,
Adrian.
