TOOLINFO
The TOOLINFO
structure contains information about a tool in a tooltip control.
typedef struct {
// ti
UINT cbSize;
UINT uFlags;
HWND hwnd;
UINT uId;
RECT rect;
HINSTANCE
hinst;
LPTSTR lpszText;
} TOOLINFO, NEAR *PTOOLINFO, FAR *LPTOOLINFO;
Members
cbSize
Size, in
bytes, of the TOOLINFO structure. This member must be specified.
uFlags
A set of bit
flags. This member can be a combination of the following values:
|
Value |
Meaning |
|
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_CENTERTIP |
Centers the
tooltip window below the tool specified by the uId member. |
|
TTF_RTLREADING |
Displays
text using right-to-left reading order on Hebrew or Arabic systems. |
|
TTF_SUBCLASS |
Indicates
that the tooltip control should subclass the tool's window to intercept
messages, such as WM_MOUSEMOVE.
If not set, you need to use the TTM_RELAYEVENT message to forward messages to
the tooltip control. For a list of messages that a tooltip control processes,
see TTM_RELAYEVENT. |
hwnd
Handle to the
window that contains the tool. If lpszText includes the
LPSTR_TEXTCALLBACK value, this member identifies the window that receives TTN_NEEDTEXT notification messages.
uId
Application-defined
identifier of the tool. If uFlags includes the TTF_IDISHWND value, uId
must specify the window handle to the tool.
rect
Coordinates
of the bounding rectangle of the tool. The coordinates are relative to the
upper-left corner of the client area of the window identified by hwnd.
If uFlags includes the TTF_IDISHWND value, this member is ignored.
hinst
Handle to the
instance that contains the string resource for the tool. If lpszText
specifies the identifier of a string resource, this member is used.
lpszText
Pointer to
the buffer that contains the text for the tool, or identifier of the string
resource that contains the text. If this member is set to the
LPSTR_TEXTCALLBACK value, the control sends the TTN_NEEDTEXT notification
message to the owner window to retrieve the text.
