IE_SETGRIDORIGIN

Sets the origin of the rules or grid lines.

Parameters

wParam

Not used; must be 0.

lParam

The low-order word has the x-coordinate of the origin and the high-order word has the y-coordinate of the origin.

Return Value

Returns IER_OK if successful; otherwise, returns IER_PARAMERR to indicate that wParam or lParam is invalid.

Comments

Rules and grids are painted after the background and before the ink (and the IN_PREPAINT notification), and are treated separately from both.

The default setting is for no grid lines. The grid lines act purely as guides for the user; the ink does not interact with the grid in any way. The specification of the grid lines is in the MM_TEXT mapping mode (that is, display pixel).
