Multiple form object creation

[kpmsivachand]

Hello guys!

In my project i need to invoke mutiple ui files. I tried QWizard, but it leads to fail. So i used QUiLoader. Consider my example, ( I am using the QT-Designer 4.4 for creating ui )

testform.h

class form1: public QWidget
{
....
....
....
};
 
class form2: public QWidget
{
....
....
....
};

class form1: public QWidget
{
....
....
....
};

class form2: public QWidget
{
....
....
....
};

form1::form1(QWidget *parent): QWidget(parent)
{
     QUiLoader loader;
 
     QFile file(":/form1.ui");
     file.open(QFile::ReadOnly);
     QWidget *formWidget = loader.load(&file, this);
     file.close();
 
     ui_inputSpinBox1 = qFindChild<QSpinBox*>(this, "inputSpinBox1");
 
     QMetaObject::connectSlotsByName(this);
 
     QVBoxLayout *layout = new QVBoxLayout;
     layout->addWidget(formWidget);
     setLayout(layout);
}
 
testform::testform(QWidget *parent): QWidget(parent)
{
     QMessageBox::information(this,tr("test"),tr("test"),QMessageBox::Ok);
     QUiLoader loader;
 
     QFile file(":/testform.ui");
     file.open(QFile::ReadOnly);
     QWidget *formWidget = loader.load(&file, this);
     file.close();
     QVBoxLayout *layout = new QVBoxLayout;
     layout->addWidget(formWidget);
     setLayout(layout);
} 
 
void form1::on_inputSpinBox1_valueChanged(int value)
{
     this->hide(); // form1 hide method called successfully
     form2 form2_object;	
     form2.show();         // This object created and as soon as closed
}

form1::form1(QWidget *parent): QWidget(parent)
{
     QUiLoader loader;

     QFile file(":/form1.ui");
     file.open(QFile::ReadOnly);
     QWidget *formWidget = loader.load(&file, this);
     file.close();

     ui_inputSpinBox1 = qFindChild<QSpinBox*>(this, "inputSpinBox1");

     QMetaObject::connectSlotsByName(this);

     QVBoxLayout *layout = new QVBoxLayout;

     file.close();
     QVBoxLayout *layout = new QVBoxLayout;
     layout->addWidget(formWidget);
     setLayout(layout);
}

My question is how to create a object for form2 from form1 method. Or else how to invoke
the form2 object from form1 method. Please help me guys.... Sorry for
such a lengthy thread.... Any hint can be Appreciated.

Include "form2.h" from "form1.cpp" and use "new form2(...)" to create the widget. It's just plain C++ you know...
