Create frameless QMessageBox

marlenet15

I have an application which is constructed as a stackwidget. When the user presses a button, a QMessageBox will pop up. I would like to take off the title of the messagebox. However, when the button is pressed, the messagebox appears BUT the application closes. What do I need to change?

void user_Data::onClickButton()
{
    QMessageBox *mb;
    mb->setWindowFlags(Qt::FramelessWindowHint |Qt::WindowStaysOnTopHint);
    mb->question(this,tr("TITLE"),tr("Are you sure you want to do this?"));
}

Hi,

Two options:

Allocate mb on the stack
Initialize mb properly (don't forget to delete it when you're done using it.)

Warning: question is a static method, so currently you're using it wrongly.

@SGaist I am not sure I follow you. How would I initialize mb properly? Oops, yes it is a warning.

SGaist

Well: you have to allocate it since you're declaring a pointer to it.

@SGaist Ok so the Application doesn't close anymore but the QMessageBox keeps showing the title bar.

Again: question is a static method, it won't make use of any of your settings.

Take a look at the Property based API chapter of QMessageBox documentation.
