class CXTPReportHeaderDragWnd;
class CXTPReportControl;
class CXTPReportColumn;
//===========================================================================
// Summary:
//     Field chooser list box control.
//     This control allows the user to move column names from associated
//     CXTPReportControl object from and to its header.
// Remarks:
//     To use a field chooser in an existing dialog box of your application,
//     add a standard list box to your dialog template using the dialog
//     editor and then initialize your CXTPReportSubListControl object
//     inside dialog OnInitialUpdate handler. See example below:
// Example:
// <code>
//  // CXTPReportSubListControl m_wndSubList;
//  wndSubList.SubclassDlgItem(IDC_COLUMNLIST, &pFieldChooserDialog);
//  // CXTPReportControl wndReport;
//  wndReport.GetReportHeader()->SetSubListCtrl(&wndSubList);
// </code>
//
// See Also:
//     CDragListBox, CXTPReportControl, CXTPReportHeader,
//     CXTPReportHeaderDragWnd, ReportControl sample application

{
	DECLARE_DYNAMIC(CXTPReportSubListControl)
public:
	//-----------------------------------------------------------------------
	// Summary:
	//     Constructs a CXTPReportSubListControl object.
	// Remarks:
	//     You construct a CXTPReportSubListControl object in two steps.
	//     First, call the constructor CXTPReportSubListControl and then call
	//     CListBox::Create, which initializes the Windows list box and
	//     attaches it to the CXTPReportSubListControl.
	// Example:
	// <code>
	// // Declare a local CXTPReportSubListControl object.
	// CXTPReportSubListControl mySubList;
	//
	// // Declare a dynamic CXTPReportSubListControl object.
	// CXTPReportSubListControl* pMySubList = new CXTPReportSubListControl;
	// </code>

	//     CXTPReportHeader::SetSubListCtrl
	//-----------------------------------------------------------------------

	// Parameters:
	//     pReportCtrl - Pointer to the associated report control.
	// Remarks:
	//     Usually this method should not be called by user, instead
	//     you should call CXTPReportHeader::SetSubListCtrl.
	// Returns:
	//     TRUE if set successfully, FALSE otherwise.

	//-----------------------------------------------------------------------

public:
	//-----------------------------------------------------------------------
	// Summary:
	//     Updates columns list data in field chooser.
	// Remarks:
	//     Reloads column list from the associated CXTPReportControl object,
	//     deletes all visible column items from the internal list,
	//     and adds the rest of invisible items.
	// Example:
	//     <code>wndSubList.UpdateList();</code>
	// Returns:
	//     TRUE when updated successfully, FALSE otherwise.
	//-----------------------------------------------------------------------

	// Summary:
	//     Not used for the moment.
	// Parameters:
	//     iSubItem - Sub-item number for including.
	// Returns:

	// Parameters:
	//     nItem - Item to begin drag
	// Remarks:
	//     Override this function if you want to control what happens when
	//     a drag operation begins. This implementation captures the mouse,
	//     creates CXTPReportHeaderDragWnd and stays in drag mode until the
	//     user clicks the left or right mouse button or presses ESC,
	//     at which time the drag operation is canceled.
	// Returns:
	//     Nonzero if dragging is allowed, otherwise 0.

	// Summary:
	//     Called by the framework when an item is being dragged within the
	//     CDragListBox object.
	// Parameters:
	//     pt - A CPoint object that contains the x and y screen coordinates of the cursor.
	// Remarks:
	//     This implementation allows dropping items only on the control itself
	//     and associated report control header.
	//     Override this function if you want to provide additional functionality.
	// Returns:
	//     The resource ID of the cursor to be displayed.
	//     The following values are possible:
	//     * <b>DL_COPYCURSOR</b>    Indicates that the item will be copied.
	//     * <b>DL_MOVECURSOR</b>    Indicates that the item will be moved.
	//     * <b>DL_STOPCURSOR</b>    Indicates that the current drop target is not acceptable.
