how to show the taskbar after maximim the window?

[Kode.Cooper]

hi there,
I create a window with flag

FramelessWindowHint

FramelessWindowHint

To copy to clipboard, switch view to plain text mode 

, and customized the
the titlebar, but when i pressed the maximim button, the window corvered the whole screen and the task bar.

I have tried the below code to. but you know, after setGeometry, the window state will not be
WindowMaximized any more.

Is the any other way for my question ? thanks .

if ( winCurState != Qt::WindowState::WindowMaximized )  
    {
		m_parent->showMaximized();
		m_parent->setGeometry(qApp->desktop()->availableGeometry());
		m_parent->updateGeometry();
        m_maxButton->setIcon( m_pixRestore );
    }
    else
    {
        m_parent->showNormal();
        m_maxButton->setIcon( m_pixMax );
    }

if ( winCurState != Qt::WindowState::WindowMaximized )  
    {
		m_parent->showMaximized();
		m_parent->setGeometry(qApp->desktop()->availableGeometry());
		m_parent->updateGeometry();
        m_maxButton->setIcon( m_pixRestore );
    }
    else
    {
        m_parent->showNormal();
        m_maxButton->setIcon( m_pixMax );
    }
