adding subwindow to MDI area

Anonymous_Banned275

The attached code does add subwindoiw as minimized , however I have not found an easy way to add the object to the area - for real .

I am actually ignorant about the "double square " icon name on the window status bar. That one put the correct window size to the MDI area - but manually - by clicking it.

Can that be done in code ?

mdiArea->addSubWindow(DDD)->
setWindowState(Qt::WindowMinimized) ;

Hi @AnneRanch,

Not sure about what you mean by "add the object the area - for real".
But did you try setWindowState(Qt::WindowMaximized); ?

Note you can also use the "Tabbed" view mode using QMdiArea::setViewMode(QMdiArea::ViewMode mode)
hope it helps

@Gojir4 The code "minimized" is NOT desired - hence it is not for real IMHO.
Yes the "maximized" works fine.
The task is to add the subwindow - such as default to "upper left corner of size the object " not as currently "minimized".
The TAB is not my objective for now, but I'll try it.

PS
Can anybody name the "double square icon " ?

@AnneRanch If you need to display the subwindow using its original size (sizehint). I think you should probably not call setWindowState at all.

The "double square icon" corrsespond to the window flag Qt::WindowMaximizeButtonHint

@Gojir4 Found the definition of the icon - officially called "restore".
It is assuming that the window was set maximize or minimize.
Then it can be "restored".
For yet unknown reason I cannot find how to build desired size of the dialog,
only minimized or maximized.

Since my code builds the area subwindow as minimized.
I should be able to "restore" it in code.
Thus I need to replace manually clicking on the "restore " icon and size the result.
Not sure where - in dialog or area...

@AnneRanch said in adding subwindow to MDI area:

Since my code builds the area subwindow as minimized.

Well, don't do that then.

default to "upper left corner of size the object "

I do not know what this even means.

If you want to position or resize the QMdiSubWindow then:

Capture the pointer to the QMdiSubWindow returned by QMdiArea::addSubWindow() (that your code line currently discards)
Then call QMdiSubWindow::resize() and/or QMdiSubWindow::move()

@ChrisW67 Before I read the last reply , I did this .
Works as required

   
       Form_SYSTEM *FS = new  Form_SYSTEM();
        
        mdiArea->addSubWindow(FS)->
                setWindowState(Qt::WindowMinimized) ;
        //modify current / last addition 
         mdiArea->currentSubWindow()->showNormal();
         mdiArea->currentSubWindow()->resize(400,400);

SOLVED
