#include "ltwrappr.h"

virtual L_INT LVectorBase::AttachToWindow(hWnd, dwFlags=VECTOR_ENGINE_DOUBLEBUFFER)

Attaches a vector handle to a window.

Parameters

HWND hWnd

Handle of the window to which the vector handle will be attached.

L_UINT32 dwFlags

Flags that modify the vector engine. Possible values are:

Value Meaning
VECTOR_ENGINE_DOUBLEBUFFER Use double buffering for flicker-free screen updates.

Returns

Value Meaning
SUCCESS The function was successful.
< 1 An error occurred. Refer to Return Codes.

Comments

This function will attach a vector handle to a window handle. All subsequent changes to the vector image will be reflected on the window.

Note: When you copy one vector to another using LVectorBase::Copy, and the source vector is attached to a window, the destination vector will NOT be attached to the same window automatically.

You can draw on the surface of any window using LVectorBase::Paint, but to use double buffering, you must attach the vector handle to a window.
