Tutorial 1: The Simplest Window
The following code uses Win32++ to create a window. This is all the code you need (in combination with Win32++) to create and display a simple window. Note that in order to add the Win32++ code to our program, we use an #include statement as shown below.
#include "wincore.h" // Note: // * Add the Win32++\include directory to project's additional include directories // A class that inherits from CWnd. It is used to create the window. class CMyWindow : public CWnd { public: CMyWindow() {} virtual void OnDestroy() { PostQuitMessage(0); } // Ends the program virtual ~CMyWindow() {} }; int APIENTRY WinMain(HINSTANCE, HINSTANCE, LPSTR, int) { // Start Win32++ CWinApp MyApp; // Create a CMyWindow object CMyWindow MyWindow; // Create (and display) the window MyWindow.Create(); // Run the application's message loop return MyApp.Run(); }
This program has four key steps:
- Start Win32++. We do this here by creating a
CWinApp
object called MyApp. - Create a
CMyWindow
object called MyWindow. - Create a default window by calling the Create function.
- Start the message loop, by calling the Run function.
The source code for this tutorial is located within the Tutorial folder of the software available from SourceForge at http://sourceforge.net/projects/win32-framework.
The
CMyWindow
class inherits from CWnd
. CWnd
is the base class for all
objects used to create windows. We override the OnDestroy
function of CWnd
to end the program when the window is closed.
