[SOLVED] QMdiSubWindow and Widget Checks

[rizoritis]

Hello,

I am using the following functions to add a subwindow to my mdiarea and to set a widget to the subwindow:

@ mdisubwindow->setWidget(widget); /Add the widget to the subwindow/
mdiarea->addSubWindow(mdisubwindow); /Add subwindow to the mdiarea/@

I would like to put if statements prior to each call to

1. first check if a widget has already been set to that particular subwindow
   2)check if the subwindow has already been added to the mdiarea

So it should look like this:

@ if(!widget is already set to mdisubwindow)
{
mdisubwindow->setWidget(widget);
}
if(!subwindow is already added to mdiarea)
{
mdiarea->addSubWindow(mdisubwindow);
} @

Any ideas would help because I cannot seem to find this anywhere...

Thanks

1. mdisubwindow->widget() will give you a reference to the current widget if any.
2. mdiarea->subWindowList() will give you a list of all the subwindows currently in the QMdiArea so you can check if mdisubwindow is among them.
