TTM_GETMAXTIPWIDTH message

Retrieves the maximum width for a tooltip window.

Parameters

wParam

Must be zero.

lParam

Must be zero.

Return value

Returns an INT value that represents the maximum tooltip width, in pixels. If no maximum width was set previously, the message returns -1.

Remarks

The maximum tooltip 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 will be displayed on a single line. The length of this line may exceed the maximum tooltip width.
