Non Square Window Shapes
I have a program somebody gave me that creates an non-square window. Has anybody else seen this? What I need to know is if there is some way to do this for a Dialog box instead of a SDI. Here is the code for SDI:
#include <windows.h>
LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);
int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance,
PSTR szCmdLine, int iCmdShow)
{
static char szAppName[] = "App Name";
static char szAppTitle[] = "App Name";
HWND hwnd;
MSG msg;
WNDCLASSEX wndclass;
wndclass.cbSize = sizeof(wndclass);
wndclass.style = CS_HREDRAW | CS_VREDRAW;
wndclass.lpfnWndProc = WndProc;
wndclass.cbClsExtra = 0;
wndclass.cbWndExtra = 0;
wndclass.hInstance = hInstance;
wndclass.hIcon = LoadIcon(NULL, IDI_APPLICATION);
wndclass.hCursor = LoadCursor(NULL, IDC_ARROW);
wndclass.hbrBackground = (HBRUSH) GetStockObject(WHITE_BRUSH );
wndclass.lpszMenuName = NULL;
wndclass.lpszClassName = szAppName;
wndclass.hIconSm = LoadIcon(NULL, IDI_APPLICATION);
RegisterClassEx(&wndclass) ;
hwnd = CreateWindow (szAppName, szAppTitle,WS_OVERLAPPEDWI NDOW,
CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,
NULL, NULL, hInstance, NULL);
ShowWindow(hwnd, iCmdShow);
UpdateWindow(hwnd);
while (GetMessage (&msg, NULL, 0, 0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return msg.wParam;
}
LRESULT CALLBACK WndProc(HWND hwnd, UINT iMsg, WPARAM wParam, LPARAM lParam)
{
HDC hdc;
PAINTSTRUCT ps;
RECT rect;
HRGN Rgn;
POINT points[5];
int AutoMagic = -1;
switch (iMsg)
{
case WM_CREATE :
SetWindowRgn(hwnd,NULL,FAL SE);
GetWindowRect(hwnd,&rect);
points[0].x = points[0].y = points[1].x = 0;
points[1].y = GetSystemMetrics(SM_CYMENU ) + GetSystemMetrics(SM_CYCAPT ION);
points[3].x = points[4].x = rect.right - rect.left;
points[4].y = 0;
points[3].y = points[1].y;
points[2].x = (rect.right - rect.left)/2;
points[2].y = rect.bottom - rect.top;
Rgn = CreatePolygonRgn(points,5, WINDING);
SetWindowRgn(hwnd,Rgn,TRUE );
return 0;
case WM_PAINT :
hdc = BeginPaint(hwnd, &ps);
GetClientRect(hwnd,&rect);
DrawText(hdc, "Inside the Window!", AutoMagic, &rect,
DT_SINGLELINE | DT_CENTER | DT_VCENTER);
EndPaint(hwnd, &ps);
return 0;
case WM_DESTROY :
PostQuitMessage(0);
return 0;
}
return DefWindowProc(hwnd, iMsg, wParam, lParam);
}
This is pretty clever programming, but is it possible for Dialog boxes and can I implement it in C++ using MSVC++5.0?

The "trick" is to use SetWindowRgn() on the dialog. After calling SetWindowRgn() with the region of how you want the dialog to look.

ok, I added more points. Could I get this translated to C++ MFC for a dialog box?
In the Window Procedure of your dialog, add:
case WM_INITDIALOG:
SetWindowRgn(hwnd,NULL,FAL SE);
GetWindowRect(hwnd,&rect);
points[0].x = points[0].y = points[1].x = 0;
points[1].y = GetSystemMetrics(SM_CYMENU ) +
GetSystemMetrics(SM_CYCAPT ION);
points[3].x = points[4].x = rect.right - rect.left;
points[4].y = 0;
points[3].y = points[1].y;
points[2].x = (rect.right - rect.left)/2;
points[2].y = rect.bottom - rect.top;
Rgn = CreatePolygonRgn(points,5, WINDING);
SetWindowRgn(hwnd,Rgn,TRUE );
return 0;
case WM_INITDIALOG:
SetWindowRgn(hwnd,NULL,FAL
GetWindowRect(hwnd,&rect);
points[0].x = points[0].y = points[1].x = 0;
points[1].y = GetSystemMetrics(SM_CYMENU
GetSystemMetrics(SM_CYCAPT
points[3].x = points[4].x = rect.right - rect.left;
points[4].y = 0;
points[3].y = points[1].y;
points[2].x = (rect.right - rect.left)/2;
points[2].y = rect.bottom - rect.top;
Rgn = CreatePolygonRgn(points,5,
SetWindowRgn(hwnd,Rgn,TRUE
return 0;
ASKER
can anybody translate the ENTIRE (as small as it is) to C++ MFC? yes I'm clueless...
