CToolTipCtrl::AddTool
Registers a tool with the tool tip control.
BOOL AddTool(
CWnd* pWnd,
UINT nIDText,
LPCRECT lpRectTool = NULL,
UINT_PTR nIDTool = 0
);
BOOL AddTool(
CWnd* pWnd,
LPCTSTR lpszText = LPSTR_TEXTCALLBACK,
LPCRECT lpRectTool = NULL,
UINT_PTR nIDTool = 0
);
Parameters
pWnd
Pointer to the window that contains the tool.nIDText
ID of the string resource that contains the text for the tool.lpRectTool
Pointer to a RECT structure containing coordinates of the tool's bounding rectangle. The coordinates are relative to the upper-left corner of the client area of the window identified by pWnd.nIDTool
ID of the tool.lpszText
Pointer to the text for the tool. If this parameter contains the value LPSTR_TEXTCALLBACK, TTN_NEEDTEXT notification messages go to the parent of the window that pWnd points to.
Return Value
Nonzero if successful; otherwise 0.
Remarks
The lpRectTool and nIDTool parameters must both be valid, or if lpRectTool is NULL, nIDTool must be 0.
A tool tip control can be associated with more than one tool. Call this function to register a tool with the tool tip control, so that the information stored in the tool tip is displayed when the cursor is on the tool.
备注
You cannot set a tool tip to a static control using AddTool.
