QDialog - no title bar

Hello!

I've wrote simple program that have main window and dialog window which can by open by clicking a button. Code of that dialog window looks like this:

Code:

---

#include <QGridLayout>
#include <QPushButton>
#include <QIcon>
 
#include "pomiary.h"
 
Pomiary::Pomiary(QWidget *parent)
    : QDialog(parent)
{
    setupUI();
}
 
void Pomiary::setupUI()
{
    setModal(true);
    setGeometry(QRect(50,0,100,150));
    setWindowIcon(QIcon(":/images/icon.png"));
 
    QGridLayout* PomiaryLayout = new QGridLayout;
    setLayout(PomiaryLayout);
 
    QPushButton *button = new QPushButton();
    button->setIcon(QIcon(":/images/icon2.png"));
    button->setIconSize(QSize(48, 48));
    button->setFixedSize(60, 60);
    PomiaryLayout->addWidget(button,0,0,Qt::AlignHCenter);
 
}

and when I open my application i don't have title bar on dialog window so I can't close it. I've tried to use setWindowFlags() but with no result. Only If I delete 'setGeometry()' window has title bar but is very small, and I want specific size. What I'm doing wrong?

thanks in advance

What if you change "0" in your setGeometry call to say... 40?

I've used setFixedSize(); and it worked perfectly.

In general I think youi are missing a point of how Qt does its job. Setting fixed size on a dialog is a bad idea and having to do that often means you did something very wrong (like not using layouts).
