This structure contains information used in handling the TTN_GETDISPINFO message.
Syntax
typedef struct tagNMTTDISPINFO {
NMHDR hdr;
LPTSTR lpszText;
TCHAR szText[80];
HINSTANCE hinst;
UINT uFlags;
LPARAM lParam;
} NMTTDISPINFO, FAR* LPNMTTDISPINFO;
Members
- hdr
NMHDR structure that contains additional information about the message.
- lpszText
Pointer to a null-terminated string that the ToolTip displays as the ToolTip text. If hinst specifies an instance handle, lpszText must be the identifier of a string resource.
- szText
Buffer that receives the ToolTip text. An application can copy the text to this buffer instead of specifying a string address or string resource. For ToolTip text that exceeds 80 characters, see the Remarks section.
- hinst
Handle to the instance that contains a string resource to be used as the ToolTip text. If lpszText is a pointer to the ToolTip text string, hinst must be NULL.
uFlags
Unsigned integer that specifies values that indicate how to interpret the idFrom member of the NMHDR structure. The following table shows the possible values.Value Description TTF_IDISHWND
Indicates that the uId member is the window handle to the tool. If this flag is not set, uId is the identifier of the tool.
TTF_RTLREADING
Displays the ToolTip text in the opposite direction to the text in the parent window.
TTF_DI_SETITEM
The ToolTip control retains the supplied information and does not request it again.
- lParam
Application-defined data associated with the tool.
Remarks
You need to point the lpszText member to your own private buffer when the text that you want to use in the ToolTip exceeds 80 characters in length. The system automatically strips the ampersand (&) accelerator characters from all strings passed to a ToolTip control, unless the control has the TTS_NOPREFIX style.
