QGraphicsView sizeIncrement

[OrlySedl]

I hope you can help me. I couldn't resize the QGraphicsView incremental 20.
main.cpp
#include <QApplication>
#include <QGraphicsView>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QGraphicsView *view = new QGraphicsView();
view->setSizeIncrement(20, 20);
view->show();
return a.exec();
}

I tried to create a View class and inherit from QGraphicsView, for function overloading
void View::resizeEvent(QResizeEvent event)
I was thinking of doing it so
this->resize(20std::round(this->width()/20), 20*std::round(this->height()/20));
BUT I can't do anything.

Hi and welcome to devnet,

What OS are you running ?

Did you notice the warning in the sizeIncrement property documentation ?

I use Ubuntu 16.04. Yes, I watched the documentation. I'm interested in how you can implement similar functionality as sizeIncrement yourself, or something like that.

You'll have to check that with the Window Manager used by your Linux distribution.
