TB_SETROWS message
Sets the number of rows of buttons in a toolbar.
Parameters
-
wParam
-
The LOWORD specifies the number of rows requested. The minimum number of rows is one, and the maximum number of rows is equal to the number of buttons in the toolbar.
The HIWORD is a BOOL that indicates whether to create more rows than requested when the system cannot create the number of rows specified by wParam. If TRUE, the system creates more rows. If FALSE, the system creates fewer rows.
-
lParam
-
Pointer to a RECT structure that receives the bounding rectangle of the toolbar after the rows are set.
Return value
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.
