open window in parent mdi

[ShapeShiftme]

Good day all.

This is my problem.
I have a page that is a subwindow of mdi1 in my code. this page is opened from the tool bar usinf the following code

menu_reports *Menu = new menu_reports;
    ui->mdi1->addSubWindow(Menu);
    Menu->showMaximized();

menu_reports *Menu = new menu_reports;
    ui->mdi1->addSubWindow(Menu);
    Menu->showMaximized();

To copy to clipboard, switch view to plain text mode 

This works fine. but on this page i have another button that must open another window but it must also be pen as a subwindow of mdi1.

So what i would like to know is how do i reference mdi from the open form.
as the following does not work

parent.mdi1
parentwidget.mdi1

parent.mdi1
parentwidget.mdi1

To copy to clipboard, switch view to plain text mode 

Any help will be greatly appreciated.
Regards

The parent of the widget inside the MDI sub-window is the child of the QMDISubwindow not the QMDIArea. You could try to qobject_cast the grandparent of your menu_reports instance and use that. However, I'd be inclined to emit a signal from menu_reports that is connected to a slot in the parent of the MDI area and have that open another sub-window.
