修正错误,这个才是,呵呵CTreeCtrl::GetCheck BOOL GetCheck( HTREEITEM hItem ) const;Return ValueNonzero if the tree control item is checked; otherwise 0.
你可以在Create时指定TVS_CHECKBOXES 或ModifyStyle(0,TVS_CHECKBOXES);你可以查一下MSDN Tree View Control Window Styles The following window styles are used when creating tree view controls. TVS_CHECKBOXES Version 4.70. Enables check boxes for items in a tree view control. A check box is displayed only if an image is associated with the item. When set to this style, the control effectively uses DrawFrameControl to create and set a state image list containing two images. State image 1 is the unchecked box and state image 2 is the checked box. Setting the state image to zero removes the check box altogether. For more information, see Working with state image indexes. Version 5.80. Displays a check box even if no image is associated with the item.Note Once a tree view control is created with this style, the style cannot be removed. Instead, you must destroy the control and create a new one in its place. Destroying the tree view control does not destroy the check box state image list. You must destroy it explicitly. Get the handle to the state image list by sending the tree view control a TVM_GETIMAGELIST message. Then destroy the image list with ImageList_Destroy.If you want to use this style, you must set the TVS_CHECKBOXES style with SetWindowLong after you create the treeview control, and before you populate the tree. Otherwise, the checkboxes might appear unchecked, depending on timing issues.TVS_DISABLEDRAGDROP Prevents the tree view control from sending TVN_BEGINDRAG notification messages. TVS_EDITLABELS Allows the user to edit the labels of tree view items. TVS_FULLROWSELECT Version 4.71. Enables full-row selection in the tree view. The entire row of the selected item is highlighted, and clicking anywhere on an item's row causes it to be selected. This style cannot be used in conjunction with the TVS_HASLINES style. TVS_HASBUTTONS Displays plus (+) and minus (-) buttons next to parent items. The user clicks the buttons to expand or collapse a parent item's list of child items. To include buttons with items at the root of the tree view, TVS_LINESATROOT must also be specified. TVS_HASLINES Uses lines to show the hierarchy of items. TVS_INFOTIP Version 4.71. Obtains tooltip information by sending the TVN_GETINFOTIP notification. TVS_LINESATROOT Uses lines to link items at the root of the tree view control. This value is ignored if TVS_HASLINES is not also specified. TVS_NOHSCROLL Version 5.80. Disables horizontal scrolling in the control. The control will not display any horizontal scroll bars. TVS_NONEVENHEIGHT Version 4.71 Sets the height of the items to an odd height with the TVM_SETITEMHEIGHT message. By default, the height of items must be an even value. TVS_NOSCROLL Version 4.71. Disables both horizontal and vertical scrolling in the control. The control will not display any scroll bars. TVS_NOTOOLTIPS Version 4.70. Disables tooltips. TVS_RTLREADING Version 4.70. Causes text to be displayed from right-to-left (RTL). Usually, windows display text left-to-right (LTR). Windows can be mirrored to display languages such as Hebrew or Arabic that read RTL. Typically, tree view text is displayed in the same direction as the text in its parent window. If TVS_RTLREADING is set, tree view text reads in the opposite direction from the text in the parent window. TVS_SHOWSELALWAYS Causes a selected item to remain selected when the tree view control loses focus. TVS_SINGLEEXPAND Version 4.71. Causes the item being selected to expand and the item being unselected to collapse upon selection in the tree view. If the mouse is used to single-click the selected item and that item is closed, it will be expanded. If the user holds down the CTRL key while selecting an item, the item being unselected will not be collapsed. Version 5.80. Causes the item being selected to expand and the item being unselected to collapse upon selection in the tree view. If the user holds down the CTRL key while selecting an item, the item being unselected will not be collapsed.TVS_TRACKSELECT Version 4.70. Enables hot tracking in a tree view control.
