Showing QMainWindow Title bar

[kavinsiva]

Hi,

in my application i need to show the title bar after some time i need to hide the title bar for that i am using following code
"HIding the title bar"

this->setWindowFlags(Qt::MSWindowsFixedSizeDialogHint);
    this->setWindowFlags(Qt::CustomizeWindowHint);
    this->setWindowFlags(Qt::FramelessWindowHint);

this->setWindowFlags(Qt::MSWindowsFixedSizeDialogHint);
    this->setWindowFlags(Qt::CustomizeWindowHint);
    this->setWindowFlags(Qt::FramelessWindowHint);

To copy to clipboard, switch view to plain text mode 

"Showing the title bar"

Qt::WindowFlags flags=windowFlags();
    flags^=Qt::WindowMinimizeButtonHint;
    setWindowFlags(flags);

Qt::WindowFlags flags=windowFlags();
    flags^=Qt::WindowMinimizeButtonHint;
    setWindowFlags(flags);

To copy to clipboard, switch view to plain text mode 

But hiding works fine for me ,show make the application crashes

on which line of code exactly does the code crash?
Run it in a debugger to see.
