Some basic operations under QT Designer

First QT Designer programming (under Visual stdio)

< a >, create a new QT Console application project in VS, open the designer and start laying out your window.

< two >, open Designer, will let you create a new form file, you can choose to inherit from Qdialog, Qwidget, Qmainwindow, qframe, etc.

< three >, after the last step (we are listed as Qmainwindow):

1, you can directly add the menu bar, the menu bar under the action event

2. Add Toolbar: Select Add Toolbar (you can add multiple) by right-click in the window margin. Is there any text under icon icons: Set toolbar properties: Toolbuttonstyle to Toolbuttontextundericon/toolbuttonicononly. The code is: Toolbar->settoolbuttonstyle (Qt::toolbuttontextundericon);

3. Add icon icons to the toolbar:
(1), create a new QRC file: such as MAINWINDOW.QRC (location: At the root of your project), then the code is as follows:

<RCC>
<qresource prefix= ":/qt_designer_test" >
<file>Icon/open.png</file>
</qresource>
</RCC>
Note: The icon folder is placed in the root directory, and Qt_designer_test is the project name folder.
(2), add resource file (QRC file):
Select Action Editor, create a new action, icon bar, select Resource, edit resource, select the icon you want, and then OK
(3), then, drag the newly created Action (action) to the toolbar

< four >, put the controls you need on the Qmainwindow, go back to vs in a compilation, get a ui_mainiwindow.h file

< five >, in the project, own a new mainwindow.h and mainwindow.cpp
Mainwindow.h

#ifndef Cwindow_h
#define Cwindow_h

#include "Generatedfiles/ui_mainwindow.h"
#include <QMainWindow>

Class Cwindow:public Qmainwindow
{
Q_object

Public
CWindow ();

Private
Ui::mainwindow UI;
};

#endif

Mainwindow.cpp

#include "Window.h"

Cwindow::cwindow ()
{
UI.SETUPUI (this);
Connect (Ui.actionexit, SIGNAL (triggered ()), this, SLOT (Close ()));
}

< six >, in the main function, add:
MainWindow Manwin;
Mainwin.show ();
Compile and run, it's OK.

Note: You can change the variable name of each control in the designer. If you want to add a Qglwidget class on Qmainwindow, the following:

Class Glarea:public Qglwidget

{
Public
Q_object

Public
Glarea (Qwidget *parent = 0);
~glarea (void);

void Initializegl ();
void Resizegl (int w, int h);
void Paintgl ();

}

Glarea::glarea (Qwidget *parent): Qglwidget (/*qglformat (qgl::D oublebuffer | QGL::D Epthbuffer | qgl::samplebuffers), */parent)

Class Mainwindow:public Qmainwindow
{
Q_object

Public
MainWindow (Qwidget *parent = 0, Qt::wflags flags = 0);
~mainwindow ();

}

Mainwindow::mainwindow (Qwidget *parent, qt::wflags flags)
: Qmainwindow (parent, flags)
{
cout << "MainWindow constructed" << Endl;
UI.SETUPUI (this);
area = new Glarea (this);//glarea is an inherited Qglwidget class
Setcentralwidget (area);

}
