SftTree/DLL 7.5 - Tree Control

FreeGDIPlusImageLoadedFromResource

Deletes a GDI+ image obtained using SftTree_LoadGDIPlusImageFromResource.

C

void SftTree_FreeGDIPlusImageLoadedFromResource(LPVOID pGDIPlusImage);

Parameters

pGDIPlusImage

A Gdiplus::Image pointer to be deleted. This value is usually obtained from a preceding call to SftTree_LoadGDIPlusImageFromResource.

Comments

Deletes a GDI+ image obtained using SftTree_LoadGDIPlusImageFromResource.

This function is mainly intended for applications written using C. Because Gdiplus is C++ based, C applications don't readily have access to the Gdiplus::Image class and cannot use delete to free a GDI+ image object. Using SftTree_FreeGDIPlusImageLoadedFromResource even C applications can use GDI+ images, without needing access to GDI+ itself.

The application retains ownership of the Gdiplus::Image pointer returned by SftTree_FreeGDIPlusImageLoadedFromResource. Once the image is no longer needed, it can be released using SftTree_FreeGDIPlusImageLoadedFromResource, which frees the associated memory.

Examples

C

        // Set a timer so we can update our progress bars every once in a while
        SetTimer(hwnd, TIMERID, 333, NULL);
        return 0;
     }
    case WM_DESTROY:
        KillTimer(hwnd, TIMERID);

        if (m_ButtonExpanded)
            SftTree_FreeGDIPlusImageLoadedFromResource(m_ButtonExpanded);
        if (m_ButtonExpandedHot)
            SftTree_FreeGDIPlusImageLoadedFromResource(m_ButtonExpandedHot);
        if (m_ButtonCollapsed)
            SftTree_FreeGDIPlusImageLoadedFromResource(m_ButtonCollapsed);
        if (m_ButtonCollapsedHot)
            SftTree_FreeGDIPlusImageLoadedFromResource(m_ButtonCollapsedHot);
        if (m_FolderClosed)
