Mdi and childe forms

mastinosoft

Hi.
I just moved from VS to Qt and have a lot of questions.
I need to know how create child form that will have the same view and functionality. Those forms just open different files but they are just clones of the same form.
I use to do like this in VS (VB)
Public AktivForm As Form //declaration

AktivForm = New MainForm // create new clone 
AktivForm.MdiParent = Me
AktivForm.Text = My.Computer.FileSystem.GetName(File Name)
AktivForm.Show()

I already found how create an MDIForm but can't find the information about child forms that I need.
Thank you

for creating a child form . just add a new widget/dialog and make it child of previous form or widget/dialog. If u want to add a form as a MDI form then u have to add a main window first time and then just add a widget . and just make this new widget to child of main window.

Thanks it makes sense but how I make dialog child of form. Maybe this is a stupid question but I just started with Qt

I add a new form to project mdichild
and in main.cpp added:

@QWidget *parent = new QWidget; @
@ChildForm *mdichild = new mdichild(parent);@

But I get 2 errors:
ChildForm undeclared identifier
mdichild undeclared identifier

What's wrong?

I think I found how to do that
@void mainwindow::on_pushButton_clicked()@
@{
mdichild *w =new mdichild(this);
w->show();
}
@

But the problem is that new windows opens outside the parent form. So my solution doesn't work.
Still need help.
