[Qt-interest] code from uic

[Zygmunt Ptak]

Hi!
Why uic generate code in header file like this:

/*************************************************************************/

#ifndef UI_UNTITLED_H
#define UI_UNTITLED_H

#include <QtCore/QVariant>
#include <QtGui/QAction>
#include <QtGui/QApplication>
#include <QtGui/QButtonGroup>
#include <QtGui/QGridLayout>
#include <QtGui/QHeaderView>
#include <QtGui/QPushButton>
#include <QtGui/QWidget>

QT_BEGIN_NAMESPACE

class Ui_Form
{
public:
    QGridLayout *gridLayout;
    QPushButton *pushButton;

    void setupUi(QWidget *Form)
    {
        if (Form->objectName().isEmpty())
            Form->setObjectName(QString::fromUtf8("Form"));
        Form->resize(400, 300);
        gridLayout = new QGridLayout(Form);
        gridLayout->setObjectName(QString::fromUtf8("gridLayout"));
        pushButton = new QPushButton(Form);
        pushButton->setObjectName(QString::fromUtf8("pushButton"));

        gridLayout->addWidget(pushButton, 0, 0, 1, 1);


        retranslateUi(Form);

        QMetaObject::connectSlotsByName(Form);
    } // setupUi

    void retranslateUi(QWidget *Form)
    {
        Form->setWindowTitle(QApplication::translate(
	  "Form", "Form", 0, QApplication::UnicodeUTF8));
        pushButton->setText(QApplication::translate(
	  "Form", "PushButton", 0, QApplication::UnicodeUTF8));
        Q_UNUSED(Form);
    } // retranslateUi

};

namespace Ui {
    class Form: public Ui_Form {};
} // namespace Ui

QT_END_NAMESPACE

#endif // UI_UNTITLED_H

/*************************************************************************/


Better is split to header and source file.

Why create next class Ui::Form???
And why Ui_Form is not called Form in namespace Ui (if we do not
generate next class)???
