How can i use ClearType on my win32 app?

Question

How can i use ClearType on my win32 app?

Daniel Shepherd 246

I am making a win32 app, and I have created text using this code:

TCHAR test[] = _T("welcome to my app :D");  
//the textout part is already in WM_PAINT.  
TextOut(hdc,  
      5, 5,  
      test, _tcslen(test));

and the text appears like this:

as you can see, the text is sort of low quality. how can I make my text look better, for example using ClearType?

Answer 1

What you are seeing is the ugly default font that Windows GDI will use.

For the Windows desktop application created by the new project template -

Step 1. Create the desired font. Store the handle to the font for later use.
Step 2. When handling WM_PAINT after calling BeginPaint select the font you created into the device context .
Step 3. Draw your text.
Step 4. Select the font out of the device context before calling EndPaint.
Step 5. Delete the font when it will not be used again.

An example (error checking omitted) -

LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
    static HFONT hFont;

    switch (message)
    {
    case WM_COMMAND:
    {
        int wmId = LOWORD(wParam);
        // Parse the menu selections:
        switch (wmId)
        {
        case IDM_ABOUT:
            DialogBox(hInst, MAKEINTRESOURCE(IDD_ABOUTBOX), hWnd, About);
            break;
        case IDM_EXIT:
            DestroyWindow(hWnd);
            break;
        default:
            return DefWindowProc(hWnd, message, wParam, lParam);
        }
    }
    break;
    case WM_CREATE:
    {
        HDC hDC = GetDC(hWnd);
        int nHeight = -MulDiv(11, GetDeviceCaps(hDC, LOGPIXELSY), 72);
        hFont = CreateFont(nHeight, 0, 0, 0, FW_NORMAL, FALSE, FALSE, FALSE, DEFAULT_CHARSET, OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS, CLEARTYPE_QUALITY, DEFAULT_PITCH, _T("Segoe UI"));
        ReleaseDC(hWnd, hDC);
    }
    case WM_PAINT:
    {
        // TODO: Add any drawing code that uses hdc here...
        PAINTSTRUCT ps;
        TCHAR szTest[] = _T("Welcome to my Font test");
        HDC hdc = BeginPaint(hWnd, &ps);
        HGDIOBJ hOld = SelectObject(hdc, (HGDIOBJ) hFont);
        TextOut(hdc, 10, 10, szTest, _tcslen(szTest));
        SelectObject(hdc, hOld);
        EndPaint(hWnd, &ps);
    }
    break;
    case WM_DESTROY:
        if (hFont)
            DeleteObject(hFont);
        PostQuitMessage(0);
        break;
    default:
        return DefWindowProc(hWnd, message, wParam, lParam);
    }
    return 0;

My code returned no errors, but it still used the ugly font. can you first show me a screenshot of an example of the better looking font?

I already posted a screenshot using the font. See below this post. If you carefully check your code I expect you will find that you did not accurately copy what I posted.

it worked. it was something with the if statement in the WM_DESTROY case statement.

You omitted the minus sign before the MulDiv function (notice that the font in my posted image is larger than yours) so you didn't accurately copy the code. Read the documentation for the CreateFont parameters, especially the formula for calculating font height for a specific point size.

Answer 2

Daniel Shepherd 246

no variables outside of the case statement are found. so the code will not work.

I don't know what you are doing but this code was tested and works correctly. The only variable that it needs is the handle to the font and that is declared as a static variable in the window procedure function. Look at line 3 in the posted code.

Please review my posted code especially the declaration of the static variable for the font handle on line three as I previously indicated. Furthermore, the code that you posted fails to include several important steps. It does not select the font handle out of the device context in the WM_PAINT handler nor does it destroy the font.

Do yourself a favor. One of the best things you can do when debugging a particular problem is to simplify things. So, I suggest you create a brand new Windows desktop application and copy the code that I posted into it. If you copy everything correctly the font will be created and used when the window is painted to write the text. Once you get that working, you should be able to see where you are not properly handling things in the code you just posted which I am not going to attempt to debug for you.
