TTM_SETMAXTIPWIDTH message
Sets the maximum width for a tooltip window.
Parameters
-
wParam
- Must be zero.
-
lParam
-
Maximum tooltip window width, or -1 to allow any width.
Return value
Returns the previous maximum tooltip width.
Remarks
The maximum width value does not indicate a tooltip window's actual width. Rather, if a tooltip string exceeds the maximum width, the control breaks the text into multiple lines, using spaces to determine line breaks. If the text cannot be segmented into multiple lines, it is displayed on a single line, which may exceed the maximum tooltip width.
