QWidget from ui

[Pavel Abrosimov]

Hello everyone.

In the books I have reading regarding qt4 the designer programm was used to create dialogs. But this time I thought the best solution was to create the ui form in designer, describe it as widget and after - use such widget as main windget in mainwindow.

I was looking in google form a lolution. I coold find some information regarding it, but it didn't work well.

What I did:

there is the ui file "mainwidget.h" as qwidget.

For the first try all I want is to see it's working:

mainwidget.h

#ifndef MAINWIDGET_H
#define MAINWIDGET_H
 
#include <QWidget>
#include "ui_mainwidget.h"
class MainWidget : public QWidget, public Ui::MainWidget
{
  Q_OBJECT
public:
  MainWidget(QWidget *parent = 0);
 
};
#endif

#ifndef MAINWIDGET_H
#define MAINWIDGET_H

#include <QWidget>
#include "ui_mainwidget.h"
class MainWidget : public QWidget, public Ui::MainWidget
{
  Q_OBJECT
public:
  MainWidget(QWidget *parent = 0);

};
#endif

To copy to clipboard, switch view to plain text mode 

and mainwidget.cpp

#include "mainwidget.h"
 
MainWidget::MainWidget(QWidget *parent) : QWidget(parent)
{
 
}

#include "mainwidget.h"

MainWidget::MainWidget(QWidget *parent) : QWidget(parent)
{

}

To copy to clipboard, switch view to plain text mode 

Then i create the main.cpp:

#include <QApplication>
#include "mainwidget.h"
 
int main(int argc, char **argv){
  QApplication app(argc, argv);
  MainWidget wgt;
  wgt.show();  
  return app.exec();
}

#include <QApplication>
#include "mainwidget.h"
 
int main(int argc, char **argv){
  QApplication app(argc, argv);
  MainWidget wgt;
  wgt.show();  
  return app.exec();
}

To copy to clipboard, switch view to plain text mode 

Then I create the .pro file, add the RESOURCES line, copy the icon's folder.
It compiles with no errors. It even does launch, but I cannot see anything - just empty window of the desired size.

Is there anything I am doing wrong in here?

try this

#include "mainwidget.h"
 
MainWidget::MainWidget(QWidget *parent) : QWidget(parent)
{
     setupUi(this);
}

#include "mainwidget.h"
 
MainWidget::MainWidget(QWidget *parent) : QWidget(parent)
{
     setupUi(this);
}
