child window with very small size !!!

[qlands]

Hi,

I have a midi application that create child windows holding a widget

The problem is that the child windows is always created with the minimum size!



When it should be something like:




I am loading the child with:

documentWindow *child = createMdiChild();
    countries *cnt = new countries(this,database);
    child->setCentralWidget(cnt);
    child->show();
    child->setWindowTitle("Countries Maintenance");

documentWindow *child = createMdiChild();
    countries *cnt = new countries(this,database);
    child->setCentralWidget(cnt);
    child->show();
    child->setWindowTitle("Countries Maintenance");

To copy to clipboard, switch view to plain text mode 

documentWindow *MainWindow::createMdiChild()
{
    documentWindow *child = new documentWindow;
    mdiArea->addSubWindow(child);
    return child;
}

documentWindow *MainWindow::createMdiChild()
{
    documentWindow *child = new documentWindow;
    mdiArea->addSubWindow(child);
    return child;
}

To copy to clipboard, switch view to plain text mode 

The centralWidget cnt has the size w=508 h=250. Its size policy is fixed.

Any idea how to correct this so the size of the child matched the size of the centralWidget?

Thanks!!!

Two questions:

1. Do you use Layouts in child widgets?
2. Do you set the size policy of child widgets?

Do you use Layouts in child widgets?
No.

Do you set the size policy of child widgets?
Yes. Is fixed.

I also tried to have a main layout in the child window and insert the child widget to the layout but I get the same problem

It's strange.
Can you post your code/form ?
