TB_SETROWS
wParam = (WPARAM) MAKEWPARAM(cRows, fLarger);
lParam = (LPARAM) (LPRECT) lprc;
Parameters
-
cRows
-
Number of rows requested. The minimum number of rows is one, and the maximum
is equal to the number of buttons in the toolbar.
-
fLarger
-
Flag that indicates whether to create more rows than requested when the system
cannot create the number of rows specified by cRows. If this parameter
is TRUE, the system creates more rows. If it is FALSE, the system creates
fewer rows.
-
lprc
-
Pointer to a RECT structure that receives the bounding rectangle of the
toolbar after the rows are set.
Return Values
No return value.
Remarks
Because the system does not break up button groups when setting the number of
rows, the resulting number of rows might differ from the number requested.
