How to hide Close Button "X" on Widget ?

Hi all

Working on Qt4.3.4 on Windows XP, I want to know how to hide Close (X) that is appearing on right hand side of the widget.


Earlier i had working on MAC OS, there i set WindowModality to Qt::ApplicationModal , then close button hides,

Is there any flag for windows to hide the close button.


Regards

Merry

Try this
setWindowFlags(Qt::WindowTitleHint);
or
setWindowFlags(Qt::WindowTitleHint | Qt::WindowMinimizeButtonHint);

Hope it helps

i want disable close button,how do that do ?

Disable or hide ??

Disable, I guess it will be difficult.

If you cannot find a way to disable or hide it.Perhaps this way would help:
1.remove the window frame by using setWindowFlags()
2.draw the window frame yourself.

But you have a bunch of work to do,if you choose this way.

Ok,I find the flag.
See the screenshot below:

use Qt::CustomizeWindowHint,you will get no X button,but also no title....

Try http://www.qtcentre.org/threads/2454...112#post142112

or alternatively, you could draw the title bar yourself.

I did it a few minutes ago for my application. In main.cpp, write:

Quote:

---

widget.setWindowFlags ( Qt::CustomizeWindowHint | Qt::WindowTitleHint);
widget.show();

Now you do not have close button, neither a menu close and ALT-F4 won't work.
Hope this can be helpful.

I'm using Qt4 under Linux

I believe another way around would be hijacking close event, add this ti header file:

Code:

---

private:
	void closeEvent(QCloseEvent *event) override;

---

and this to cpp file:

Code:

---

void MainWindow::closeEvent(QCloseEvent *event)
{
	cout << "Here in close" << endl;
	event->ignore();
}
