TTM_ADDTOOL message
Registers a tool with a tooltip control.
Parameters
-
wParam
- Must be zero.
-
lParam
-
Pointer to a TOOLINFO structure containing information that the tooltip control needs to display text for the tool. The cbSize member of this structure must be filled in before sending this message.
Return value
Returns TRUE if successful, or FALSE otherwise.
Remarks
Although the name of the message implicitly indicates the "addition of a tool", it must be made clear that this message merely records a set of specific settings for what is called "a tool", however a ToolTip can be displayed even when there is no "tool" itself (a visual control with a handle). For this reason, this message should be interpreted as "add a set of specific settings for the display of a ToolTip ". A ToolTip window can be displayed in several different ways and each of these ways can be registered via the TTM_ADDTOOL message.
