CTreeCtrl::Create

Статья
10/16/2008

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.

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

Параметры

dwStyle
Specifies the tree view control's style. Apply window styles, described in CreateWindow, and any combination of tree view control styles as described in the Windows SDK.
rect
Specifies the tree view control's size and position. It can be either a CRect object or a RECT 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.

Возвращаемое значение

Nonzero if initialization was successful; otherwise 0.

Заметки

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.

To create a tree control with extended window styles, call CreateEx instead of Create.

Пример

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

m_TreeCtrl.Create(WS_VISIBLE | WS_TABSTOP | WS_CHILD | WS_BORDER
   | TVS_HASBUTTONS | TVS_LINESATROOT | TVS_HASLINES
   | TVS_DISABLEDRAGDROP | TVS_NOTOOLTIPS | TVS_EDITLABELS,
   CRect(10, 10, 300, 100), this, ID_MYTREE);

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