          </p>
          <p>
            CanExpand calls the inherited method to signal the OnExpanding event handler (when assigned). No additional actions are performed if the inherited method returns <b>False</b>.

            <var>CanExpand</var> temporarily disables the <var>AutoExpand</var> functionality in the shell control, and removes all child tree nodes in <var>Node</var>. The child nodes are re-created using the <var>PopulateTreeNodeWithFiles</var> method. This ensures that the shell control reflects the current content in the local file system during execution of the method. The value in <var>AutoExpand</var> is restored to its original value prior to exiting from the method.

          <p>
            The entire update process is done in a BeginUpdate  / EndUpdate block to reduce the number of screen refreshes in the method.

          <p>
            No actions are performed in the method at design-time, or when <var>Root</var>  contains an empty string (<b>''</b>).
          </p>
          <p>
            <var>PopulateWithRoot</var> calls the internal <var>GetFilesInDir</var> helper to get a list of file system items for the path which match the <var>Mask</var> and <var>ObjectTypes</var> specified for the control. Each of the files in the list are passed to <var>DoAddItem</var> / <var>OnAddItem</var> to determine if they can be added to the <var>Items</var> in the control.
          </p>
          <p>
            A <var>TListItem</var> instance is added to Items to represent the files or directories. The <var>Data</var> property in the list item is used to store a pointer to the file size. Values are added to <var>SubItems</var> with the string representation for the file size, and the file extension.
          </p>
          <p>
            When <var>UseBuiltInIcons</var> is set to <b>True</b>, the <var>GetBuiltInImageIndex</var> method is called to get the <var>ImageIndex</var> for the built-in icon for a list item. This action is performed using the path to the current file name when LargeImages  and/or SmallImages have not been assigned. The value in <var>ViewStyle</var> determines the image size requested. When ViewStyle is <var>vsIcon</var>, LargeImages is checked (when assigned). Otherwise, <var>SmalImages</var> is checked (when assigned). If an imagelist exists in either LargeImages or SmallImages, the existing ImageIndex in the list item is used.
          </p>
          <p>
            The <var>OnFileAdded</var> event handler is signalled (when assigned) for each new entry added to Items.
          </p>
          <p>
            The <var>Sort</var> method is called prior to exit to order the Items in the control using the option specified in the <var>FileSortType</var> property.

            <var>Resize</var> is a method used to set the size for <var>Columns</var> in the list view control. <var>Resize</var> calls the inherited method, and checks the <var>Columns</var> defined for the control. The <var>Width</var> property is used to determine the layout sizes applied to the columns for the control.

        <p>
          When <var>ALargeImage</var> is <b>True</b>, the index value refers to a large image as used in the vsIcon view style. When set to <b>False</b>, it refers to a small image as used in the other view styles.

        <p>
          GetBuiltinImageIndex calls the GetBuiltInImageIndex method in the widgetset class to get the return value for the method. The widgetset class handles storing the built-in image to the correct image list when the handle for the image list has not already been assigned.

          GetBuiltinImageIndex is called from the <var>PopulateWithRoot</var> method when <var>UseBuiltInIcons</var> is set to <b>True</b>.

          In the current LCL version, GetBuiltinImageIndex is implemented for the Windows platform only.

            ParentColor determines if the control should use the Color from the Parent control, when enabled. The default value for the property is False in TShellListView.
          </p>
          <p>
            When this property is True, all changes to the Color of the parent will also be applied to the Color of the control, ensuring that they both contain same value. If the Color of the control is changed by the application, then ParentColor will be automatically set to False.
          </p>
          <p>
            Using ParentColor when the Color value is clDefault can cause problems in resolving the actual color value. To obtain the Color property of a control while taking into account clDefault and ParentColor, use the GetColorResolvingParent method. This method might return a non-RGB color, but will never return clDefault. To obtain a purely RGB result use the GetRGBColorResolvingParent method.
