C++ button

[lumpybanana247]

this is kind of a lame question, but in C++ (mingw/devc++ for example) how do you simply add a button to your window (assuming your window is set up something like...)

#include <windows.h>
LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM);
char szClassName[ ] = "WindowsApp";
int WINAPI WinMain(HINSTANCE hThisInstance, HINSTANCE hPrevInstance, LPSTR lpszCmdArgumentCmdLine, int nCmdShow) 
{
    HWND hwnd;          
    MSG messages;         
    WNDCLASSEX wincl;  
    wincl.hInstance = hThisInstance;
    wincl.lpszClassName = szClassName;
    wincl.lpfnWndProc = WindowProcedure;  
    wincl.style = CS_DBLCLKS; 
    wincl.cbSize = sizeof (WNDCLASSEX);
    wincl.hIcon = LoadIcon (NULL, IDI_APPLICATION);
    wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION);
    wincl.hCursor = LoadCursor (NULL, IDC_ARROW);
    wincl.lpszMenuName = NULL;
    wincl.cbClsExtra = 0;
    wincl.cbWndExtra = 0;  
    wincl.hbrBackground = (HBRUSH) COLOR_BACKGROUND;
    if (!RegisterClassEx (&wincl))
    return 0;
    hwnd = CreateWindowEx (0, szClassName, "Windows App", WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, 544, 375, HWND_DESKTOP, NULL,hThisInstance, NULL);
    ShowWindow (hwnd, nCmdShow);
    while (GetMessage (&messages, NULL, 0, 0))
    {
        TranslateMessage(&messages);
        DispatchMessage(&messages);
    }
    return messages.wParam;
}
LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
    switch (message)                
    {
        case WM_DESTROY:
            PostQuitMessage (0);      
            break;
        default:                    
            return DefWindowProc (hwnd, message, wParam, lParam);
    }
    return 0;
}

Your code is the basic window setup any Win32 API tutorial will show you. Continue reading the tutorial (or preferably, Petzold's book), to see how to add buttons.

You call the function CreateWindow (or CreateWindowEx) . One of the things about Windows is that everything, window, dialogue box, buttons and other controls is a window. Just with differing behaviour.

Anyway look up CreateWindow(Ex ) on MSDN and it will tell you how.
