C++ Syntax

void

MKI_HookPositionProc(

__int32 f_nWindowNum,

MKI_POINT_PTR f_pPosition );

typedef void

(*MKI_HOOKPOSITION_PROC)(

__int32 f_nWindowNum,

MKI_POINT_PTR f_pPosition );

This callback procedure is called once each time the current cursor's position is changed.

Parameters

WindowNum

[__int32] Zero-based index of the drawing window that is responsible for the event. Valid range: 0 <= Value < MKI_WINDOW_MAX (standard windows) or Value = MKI_WINDOW_VIEW (view window).

Position

[MKI_POINT_PTR] Address of a point structure containing the cursor's new position in internal [mm] (relative to the page center, scale-independent). The plug-in may alter these values to force a special movement of the cursor. Both the cursor and the coordinate display will react accordingly. Anyway, be sure to use this possibility only if required, as another plug-in might also try to do so!

Comment

A hook on cursor position calculation can be established and cancelled using the procedures MKI_HookPositionStart and MKI_HookPositionEnd.

The name MKI_HookPositionProc is only a placeholder, the procedure may have any name.
