Please note that I mean overlapping windows in a literal sense, not in the DWSTYLE sense listed within this very function.
I've been having this problem for quite a while now whereby I create a number of windows using the above function and have been having issues with the main, parent window not overlapping when brought into focus. Really I have three main objectives I wish to have work in unison yet at the moment, I seem to only be able to have one work at any given time.
1)For each of the created windows to be brought forward into focus whenever clicked, whether that be the first or twenty first created window.
2)For only a single program instance to appear on the taskbar in windows.
3)For each created window to share the same wndproc. E.g. if one window minimizes, as do all the rest.
I start off by creating all relevant usual parameters required for creating the window.
//Setup the window class itself.
WNDCLASSEX wcex;
wcex.cbClsExtra = 0; //Remain at zero
wcex.cbSize = sizeof(WNDCLASSEX); //Byte size of the struct
wcex.cbWndExtra = 0; //Remain at zero
wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW+2); //Window background colour value.
wcex.hCursor = LoadCursor(NULL, IDC_ARROW); //Application cursor
wcex.hIcon = 0; //Window icon
wcex.hIconSm = 0; //Small window icon
wcex.hInstance = newHandle.hInstance; //Window handle.
wcex.lpfnWndProc = (WNDPROC)msgProc; //Window procedure.
wcex.lpszClassName = "DirectX Class"; //Window main name.
wcex.lpszMenuName = NULL; //Here to add a menu system.
wcex.style = CS_HREDRAW | CS_VREDRAW | CS_NOCLOSE | CS_DBLCLKS; //Class style. See http://msdn.microsoft.com/en-us/library/ms633574(VS.85).aspx
//Register the desired window class parameters to the system.
if(FAILED(RegisterClassEx(&wcex)))
return DDIS_ERR_INIT_REGISTERCLASSEX;
//Setup the window style.
DWORD dwStyle = WS_CAPTION | WS_SYSMENU | WS_THICKFRAME | WS_MINIMIZEBOX;After having done this, I have the option to include this following code snippet.
//Set the first window created as the main window, if applicable.
//HEREMARK - This stops the main parent window from ever being the front, main window in case of an overlap. Why?
HWND parentWindow = NULL;
if((int)displayHandles.size() > 0)
parentWindow = displayHandles.at(0).wndHandle;I then create the window as per usual:
//Creates the window with appropriate values.
if(!(newHandle.wndHandle = CreateWindow("DirectX Class", //Must be the same as wcex.lpszClassName.
APPLICATION_NAME.c_str(), //Window title bar name.
dwStyle, //Styles associated with the newly created window.
xPos, //X Position.
yPos, //Y Position.
xSize, //Width.
ySize, //Height.
parentWindow, //Window parent. Defaults to windows if unset.
NULL, //Menu handle.
newHandle.hInstance, //Handle to the window instance this will be associated with.
this))) //For client/child windows. See http://msdn.microsoft.com/en-us/library/ms632679(VS.85).aspx.If I set the parent window as in the second code snippet, all of the windows get grouped as one program on the taskbar and each windows window message gets shared so tick off requirements 2 and 3. The main, parent window however, will refuse to be drawn on top of the other windows, no matter how I try to influence it (not the SetFocus function doesn't achieve this either).
If I simply set no parentWindow up, each window will happily overlap correctly so tick of requirement number one. Each window however then acts individually and is represented as a seperate program on the taskbar (closing down one will still close down all of the rest however).
I'm pretty sure I'm just missing something like a simple DWSTYLE input but I can't for the life of me figure out which one(s) to use.
Any pointers would be massively appreciated, thanks.
edit:Argh @ reformatting being different from preview and the actual post! :D
