如何在ctree view 中改变tree 的风格？

[depechemode]

树控制CTreeCtrl::Create的调用格式如下：

BOOL Create( DWORD dwStyle, const RECT& rect, CWnd* pParentWnd, UINT nID );

其中参数dwStyle用来确定树控制的类型；rect用来确定树控制的大小和位置；pParentWnd用来确定树控制的父窗口，通用是一个对话框并且不能为NULL；nID用来确定树控制的标识。树控制的风格可以是下列值的组合：
在C TREE VIEW 中，如何获得nID?

[bluecrest]

nID是自己在resource.h中定义
或者在contrl中添加时，property设置

[woodswoods]

CTreeCtrl::Create
BOOL Create( DWORD dwStyle, const RECT& rect, CWnd* pParentWnd, UINT nID );

Return Value

Nonzero if initialization was successful; otherwise 0.

Parameters

dwStyle

Specifies the tree view control’s style. Apply any combination of tree view control styles to the control.

rect

Specifies the tree view control’s size and position. It can be either a CRect object or aRECT structure.

pParentWnd

Specifies the tree view control’s parent window, usually a CDialog. It must not be NULL.

nID

Specifies the tree view control’s ID.

Remarks

If you specify the tree control in a dialog box template, or if you are using CTreeView, your tree control is created automatically when the dialog box or view is created. If you want to create the tree control as a child window of some other window, use the Create member function. If you create the tree control using Create, you must pass it WS_VISIBLE, in addition to other tree view styles.

You construct a CTreeCtrl in two steps. First call the constructor, then call Create, which creates the tree view control and attaches it to the CTreeCtrl object.

The following styles can be applied to a tree view control:

TVS_HASLINES The tree view control has lines linking child items to their corresponding parent items.


TVS_LINESATROOT The tree view control has lines linking child items to the root of the hierarchy.


TVS_HASBUTTONS The tree view control adds a button to the left of each parent item.


TVS_EDITLABELS The tree view control allows the user to edit the labels of tree view items.


TVS_SHOWSELALWAYS Causes a selected item to remain selected when the tree-view control loses focus.


TVS_DISABLEDRAGDROP The tree-view control is prevented from sending TVN_BEGINDRAG notification messages.


TVS_NOTOOLTIPS The tree view control uses no tooltips.


TVS_SINGLEEXPAND When this style is enabled, changing the selection in the tree view will automatically cause the item being selected to expand and the item being unselected to collapse. If the mouse is used to single-click the selected item and that item is closed, it will be expanded. If the selected item is single-clicked when it is open, it will be collapsed.
Example

// Assuming your window has a CTreeCtrl member named m_TreeCtrl,
// you can create the tree control window with a child ID of 0x1005
// using a call like this:

m_TreeCtrl->Create(WS_VISIBLE | WS_TABSTOP | WS_CHILD | WS_BORDER
| TVS_HASBUTTONS | TVS_LINESATROOT | TVS_HASLINES
| TVS_DISABLEDRAGDROP,
CRect(10, 10, 300, 100), this, 0x1005);

// The control will have the appropiate window styles, and the tree
// control styles specified are those most commonly used.

树型控件的nID是在资源模板中定义的，是个整形量，你可以直接引用

[ZHENG017]

CTreeCtrl *pTree=&GetTreeCtrl();
SetWIndowLong(....)

[depechemode]

我已经知道了,感谢各位大哥
我是在 CTreeView中使用的
所以,
CTreeCtrl *p=GetTreeCtrl();
即可.
