Confirm and Notify Window Position

[CodeChomper]

It would be really nice to be able to set the Notify and Confirm window positions! Currently they pop up in the middle of the screen and I would like them to pop up in the middle of my application.

I checked to make sure the messagebox was properly parented to the active window and it is. This is the default behavior of Win32, so I believe this should be how our API works.

I was curious to see if it was possible to change the position of dialogs and I found this:

I created this example but the call to SetWindowPos seems to have no effect on the messagebox position:

#include "UltraEngine.h"

using namespace UltraEngine;

//https://stackoverflow.com/questions/1530561/set-location-of-messagebox

// global hook procedure
HHOOK hhookCBTProc = 0;

LRESULT CALLBACK pfnCBTMsgBoxHook(int nCode, WPARAM wParam, LPARAM lParam)
{
    if (nCode == HCBT_CREATEWND)
    {
        CREATESTRUCT* pcs = ((CBT_CREATEWND*)lParam)->lpcs;

        if ((pcs->style & WS_DLGFRAME) || (pcs->style & WS_POPUP))
        {
            HWND hwnd = (HWND)wParam;

            // At this point you have the hwnd of the newly created 
            // message box that so you can position it at will

            RECT rect;
            GetWindowRect(hwnd, &rect);
            int w = rect.right - rect.left;
            int h = rect.bottom - rect.top;

            HWND phwnd = GetActiveWindow();
            if (phwnd)
            {
                GetWindowRect(phwnd, &rect);
                int x = ((rect.right - rect.left) - w) / 2;
                int y = ((rect.bottom - rect.top) - h) / 2;

                //Neither of these seem to have any effect:
                //MoveWindow(hwnd, x, y, w, h, true);
                SetWindowPos(hwnd, NULL, x, y, 0, 0, SWP_NOOWNERZORDER | SWP_NOSIZE | SWP_NOZORDER);
            }
        }
    }
    return (CallNextHookEx(hhookCBTProc, nCode, wParam, lParam));
}

int main(int argc, const char* argv[])
{
    //Get the displays
    auto displays = GetDisplays();

    //Create a window
    auto window = CreateWindow("Ultra Engine", 0, 0, 800, 600, displays[0]);

    HWND hwnd = window->GetHandle();

    hhookCBTProc = SetWindowsHookEx(WH_CBT, pfnCBTMsgBoxHook, 0, GetCurrentThreadId());
    Notify("test");
    UnhookWindowsHookEx(hhookCBTProc);

    //Create User Interface
    auto ui = CreateInterface(window);
    
    while (true)
    {
        const Event ev = WaitEvent();
        switch (ev.id)
        {
        case EVENT_WINDOWCLOSE:
            return 0;
            break;
        }
    }
    return 0;
}
