The clistctrl class encapsulates the "List View Control" function to display the collection of each containing icon (in List View) and label. In addition to icons and labels, each item can also display information in the column on the Right of icons and labels. This control (and clistctrl class) is only applicable to programs running on Windows 95, Windows NT 3.51, and later. The following is an overview of the clistctrl class. For a detailed and conceptual discussion, see "use clistctrl" and "control topic" in the "Visual C ++ programmer's Guide ". The view List View control can display its content in four different ways, called "View ".

·	Each item in the icon view is displayed as a full-size icon (32 × 32 pixels). There is a label below it. You can drag an item to any position in the List View window.
·	Each item in the small icon view appears as a small icon (16 × 16 pixels), with a label on the right. You can drag an item to any position in the List View window.
·	Each item in the List View appears as a small icon. There is a label below. Items are arranged in columns and cannot be dragged to any position in the List View window.
·	Each item in the report view appears on the row, and additional information is arranged in columns on the right. The leftmost column contains icons and labels, and the next column contains the child items specified by the application. Embed the title control to implement these columns. For more information about report view title controls and columns, see "use clistctrl: add columns to controls (Report view)" in the "Visual C ++ programmer Guide )".

The current list view style of the control specifies the current view. For more information about these styles and their usage, see "use clistctrl: change the style of list controls" in the "Visual C ++ programmer Guide ". In addition to the standard list style, the clistctrl class supports a series of extended styles that provide rich functions. Some examples of this function include:

·	If the cursor remains on an item for a period of time, this item can be selected automatically.
·	If the virtual list view is valid, DWORD items are supported by the control. It is possible to put the management application item data at the top. Except Item Selection and focus information, all item information must be managed by the application. For more information, see "use clistctrl: Virtual list control" in the "Visual C ++ programmer Guide ".
·	Click or double-click activation. If activation is effective, hot tracking (item text is automatically highlighted) and click or double-click the highlighted item to activate it.
·	If the drag-and-drop LIST command is valid, you can drag and drop records in columns in the List View control. Valid only for the report view.

For more information about how to use the new extended style, see "use clistctrl: change the style of list controls" in the "Visual C ++ programmer Guide" in the online document ". Each item in the item and subitem List View Control contains an icon, a tag, a current status, and an application definition value ("item data "). One or more sub-items can be associated with each item. A "subitem" is a string that can be displayed in the item icon and column on the right of the label in the report view. Each item in the List View control must be the same as the number of subitems. Clistctrl class provides functions for inserting, deleting, searching, and changing these items. For more information, see "use clistctrl: scrolling, sorting, sorting, and searching in the list control" in the "Visual C ++ programmer Guide ". For more information, see clistctrl: getitem, clistctrl: insertitem, and clistctrl: finditem. The List View control stores the icons and text attributes of an item. However, in addition to these item types, clistctrl supports "Callback items ". A "Callback item" is a list view item. Each application date is not the control date to store text, icons, or both. The callback mask is used to specify the attribute (text and/or icon) provided by the application. If the app uses a callback item, it must provide text and/or icon properties as needed. Callback items are helpful when some of the information about your application already exists. For more information, see clistctrl: getcallbackmask and "use clistctrl: callback item and callback mask ". The image list icon, title item image, and application-defined list view item statuses are included in some image lists (implemented by the cimagelist class) and can be created and assigned to List View Controls. Each list view control can have more than four image list types:

·	Use the big icon in the icon view to obtain the full-size icon.
·	Small icons are used in small icons, lists, and report views to obtain the small version icons used in the icon view.
·	The application-defined status includes a status image, which is displayed next to the item icon to indicate an application-defined status.
·	The title item is used to obtain a small image that appears in each title Control item in the report view.

The List View control deletes the image list assigned to it (when it is deleted). However, developers can delete the list of images that are no longer used by the application. # Include <afxcen. h> see Member constructors of the cimagelist clistctrl class.
