QMainWindow with QMainWindow

[baray98]

I have an action in my QMainWindow, mainWindow1, that will show another QMainWindow which is a child of mainWindow1, I wanted to show this second mainwindow in a Non-Modal fashion, but its just wont go away in front of my mainWindow1 . The second QMainWindow is not blocking input on my mainWindow1 in any case but it keeps itself in front of my mainWindow1 even if click my mouse to mainWindow1.

//in my mainwindow 1 i poped the other mainwindow like this 
 
if (m_mainWindow2 ==  NULL)
{
    m_mainWindow2 = new QMainWindow(this);
}
 
m_mainWindow2 ->show();

//in my mainwindow 1 i poped the other mainwindow like this 

if (m_mainWindow2 ==  NULL)
{
    m_mainWindow2 = new QMainWindow(this);
}

m_mainWindow2 ->show();

To copy to clipboard, switch view to plain text mode 

I tried playing with the windowFlags and windowModality with no luck .... anybody please help..
