Is this your first time with GUIs??? If so, i suggest learning Gtk+ first, it makes understanding Win32 much easier
Technically, you could make a window with just this:
#include <windows.h>
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int CmdShow)
{
MessageBox(NULL, TEXT("First Program"), TEXT("First"), MB_OK );
return 0;
}But normally a Win32 window looks like this:
#include <windows.h>
LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);
int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow )
{
MSG msg ;
HWND hwnd;
WNDCLASS wc;
wc.style = CS_HREDRAW | CS_VREDRAW;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.lpszClassName = TEXT( "Window" );
wc.hInstance = hInstance ;
wc.hbrBackground = GetSysColorBrush(COLOR_3DFACE);
wc.lpszMenuName = NULL;
wc.lpfnWndProc = WndProc;
wc.hCursor = LoadCursor(NULL, IDC_ARROW);
wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);
RegisterClass(&wc);
hwnd = CreateWindow( wc.lpszClassName, TEXT("Window"),
WS_OVERLAPPEDWINDOW | WS_VISIBLE,
100, 100, 250, 150, NULL, NULL, hInstance, NULL);
ShowWindow(hwnd, nCmdShow);
UpdateWindow(hwnd);
while( GetMessage(&msg, NULL, 0, 0)) {
DispatchMessage(&msg);
}
return (int) msg.wParam;
}
LRESULT CALLBACK WndProc( HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam )
{
switch(msg)
{
case WM_DESTROY:
{
PostQuitMessage(0);
return 0;
}
}
return DefWindowProc(hwnd, msg, wParam, lParam);
}seems like a lot of crap for just a simple window, right? Well everything in that example has a purpose.
This explains it very well:
