How to show a frameless dialog - DOESN'T WORK

Hi to all,
I would show a frameless dialog from my gui but I can't.
This is my code:

Code:

---

#ifndef __INFODLG_H__
#define __INFODLG_H__
 
#include "GeneratedFiles/ui_infoDlg.h"
#include <QDialog>
 
class MainWindow;
 
class InfoDlg : public QDialog
{
 
public:
	InfoDlg( QWidget *parent );
	virtual ~InfoDlg();
 
private slots:
 
protected:
 
private:
	Ui::infoDlg ui;
	MainWindow* win;
};
 
#endif __INFODLG_H__

---

and the *.cpp

Code:

---

#include "InfoDlg.h"
 
InfoDlg::InfoDlg( QWidget *parent )
: QDialog(parent)
{
	ui.setupUi(this);
	setWindowFlags( Qt::FramelessWindowHint );
	win = (MainWindow*)parent;
}
 
InfoDlg::~InfoDlg()
{
}

---

here I create the dialog

Code:

---

void MainWindow::test()
{
	InfoDlg dlg(this);
	dlg.exec();
}

---

Unfortunately it doesn't work. I tried either with exec and show methods without success.

Where is the problem?

Regards

You've got an example of a frameless QDialog in Qt Demo. Have a look at widgets -> windows flags

Hi

I use this code and all works fine.

Code:

---

DlgAbout *d = new DlgAbout(0,0,"1.00.00"); // QDialog
  d->setWindowTitle(tr("About"));
  d->setWindowFlags(Qt::FramelessWindowHint | Qt::Dialog);
  d->show();

---

Note: DlgAbout is a gui create with Qt4 Designer

It works thank you very much.
The problem was the Qt::Dialog missed.

Now I would do the dialog background transparent :-)

Hi,

I have a problem on SDK (OS:Windows Vista).
I also use setWindowFlags((this->windowFlags()|Qt::FramelessWindowHint) ,but it still have gray line around window.
Can somebody help ....?
