Removing unnecessary things from windows_util.cpp

[DinkydauSet]

A lot in that file has become unnecessary because of the new GUI made with nana. Removed headers:

//#include <Windowsx.h>
//#include <CommCtrl.h>
//#include <tchar.h>

removed other code:

HWND WINAPI CreateTrackbar(
    HWND hwndDlg,  // handle of dialog box (parent window) 
    UINT selMin,     // minimum value in trackbar range 
    UINT selMax,     // maximum value in trackbar range
    int xPos, int yPos,
    int hSize, int vSize,
    int id,
    HINSTANCE hInst)
{
    HWND hwndTrack = CreateWindowEx(
        0,                               // no extended styles 
        TRACKBAR_CLASS,                  // class name 
        _T("Trackbar Control"),              // title (caption) 
        WS_CHILD |
        WS_VISIBLE |
        TBS_AUTOTICKS |
        TBS_ENABLESELRANGE,              // style 
        xPos, yPos,                          // position 
        hSize, vSize,                         // size 
        hwndDlg,                         // parent window 
        (HMENU)id,                     // control id 
        hInst,                         // instance 
        NULL                             // no WM_CREATE parameter 
    );
    SendMessage(hwndTrack, TBM_SETRANGE,
        (WPARAM)TRUE,                   // redraw flag 
        (LPARAM)MAKELONG(selMin, selMax));  // min. & max. positions
    SendMessage(hwndTrack, TBM_SETPAGESIZE,
        0, (LPARAM)4);                  // new page size 
    SendMessage(hwndTrack, TBM_SETPOS,
        (WPARAM)TRUE,                   // redraw flag 
        (LPARAM)selMin);
    SetFocus(hwndTrack);
    return hwndTrack;
}

BOOL DrawBitmap(HDC hDC, int x, int y, HBITMAP& hBitmap, DWORD dwROP, int screenWidth, int screenHeight) {
    if(debug) cout << "drawing (windows api DrawBitmap)" << endl;
    HDC hDCBits;
    BOOL bResult;
    if (!hDC || !hBitmap)
        return FALSE;
    hDCBits = CreateCompatibleDC(hDC);
    SelectObject(hDCBits, hBitmap);

    bResult = BitBlt(hDC, x, y, screenWidth, screenHeight, hDCBits, 0, 0, dwROP);

    DeleteDC(hDCBits);
    return bResult;
}

I used this for the transition to the nana GUI:

class Win32BitmapManager : public BitmapManager {
public:
    ARGB* ptPixels;
    HBITMAP screenBMP;
    int screenWidth;
    int screenHeight;
    HWND* hWnd;

    Win32BitmapManager() {}
    Win32BitmapManager(HWND* hWnd) {
        this->hWnd = hWnd;
    }

    ARGB* realloc(uint newScreenWidth, uint newScreenHeight) {
        int newScreenWidthInt = newScreenWidth;
        int newScreenHeightInt = newScreenHeight;

        DeleteObject(screenBMP);
        HDC hdc = CreateDCA("DISPLAY", NULL, NULL, NULL);
        BITMAPINFO RGB32BitsBITMAPINFO;
        ZeroMemory(&RGB32BitsBITMAPINFO, sizeof(BITMAPINFO));
        RGB32BitsBITMAPINFO.bmiHeader.biSize = sizeof(BITMAPINFOHEADER);
        RGB32BitsBITMAPINFO.bmiHeader.biWidth = newScreenWidthInt;
        RGB32BitsBITMAPINFO.bmiHeader.biHeight = -newScreenHeightInt; //for real - this needs to be negative https://stackoverflow.com/questions/19870141/createbitmap-returns-upside-down-image
        RGB32BitsBITMAPINFO.bmiHeader.biPlanes = 1;
        RGB32BitsBITMAPINFO.bmiHeader.biBitCount = 32;
        screenBMP = CreateDIBSection(
            hdc,
            (BITMAPINFO*)&RGB32BitsBITMAPINFO,
            DIB_RGB_COLORS,
            (void**)&ptPixels,
            NULL, 0
        );
        screenWidth = newScreenWidthInt;
        screenHeight = newScreenHeightInt;
        return ptPixels;
    }

    void draw() {
        HDC hdc = GetDC(*hWnd);
        DrawBitmap(hdc, 0, 0, screenBMP, SRCCOPY, screenWidth, screenHeight);
        ReleaseDC(*hWnd, hdc);
    }
};

Version of BrowseFile without a parent HWND (not used anymore):

int BrowseFile(BOOL bOpen, const char *szTitle, const char *szExt, std::string &szFile) {
    char buffer[1024] = { 0 };
    strncpy(buffer, szFile.c_str(), sizeof(buffer));
    buffer[sizeof(buffer) - 1] = 0;
    OPENFILENAMEA ofn = { sizeof(OPENFILENAME) };
    ofn.hInstance = GetModuleHandle(NULL);
    ofn.lpstrFile = buffer;
    ofn.lpstrTitle = szTitle;
    ofn.nMaxFile = sizeof(buffer);
    //ofn.hwndOwner = hwParent;
    ofn.lpstrFilter = szExt;
    ofn.nFilterIndex = 1;
    if (bOpen) {
        ofn.Flags = OFN_SHOWHELP | OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
        int ret = GetOpenFileNameA(&ofn);
        if (ret)
        {
            szFile = buffer;
        }
        return ret;
    }
    else {
        ofn.Flags = OFN_SHOWHELP | OFN_OVERWRITEPROMPT | OFN_HIDEREADONLY;
        if (GetSaveFileNameA(&ofn)) {
            szFile = buffer;
            char *s = strrchr(buffer, '\\');
            if (!s)
                s = buffer;
            else
                s++;
            if (!strrchr(s, '.')) {
                const char *e = szExt;
                e += strlen(e) + 1;
                if (*e) {
                    for (int i = 1; i < (int)ofn.nFilterIndex; i++) {
                        e += strlen(e) + 1;
                        if (!*e)
                            break;
                        e += strlen(e) + 1;
                        if (!*e)
                            break;
                    }
                }
                if (strstr(e, "."))
                    e = strstr(e, ".");
                szFile += e;
            }
            return 1;
        }
        else
            return 0;
    }
}
