LVectorWindow::CreateWnd

#include "ltwrappr.h"

HWND LVectorWindow::CreateWnd(hWndParent, nID=0, dwStyle=WS_VISIBLE|L_BS_PROCESSKEYBOARD, x=0, y=0, nCx=200, nCy=200)

Creates the vector window control using the specified parameters.

Parameters

HWND hWndParent

Handle of the parent window.

L_INT nID

The controls ID.

DWORD dwStyle

The style of the window control. Apply any combination of window styles and LEAD window styles. For more information on Windows styles, refer to your compilers help file. Currently only the LEAD style L_BS_PROCESSKEYBOARD (to enable keyboard processing) is supported for the LVectorWindow class.

L_INT x

X coordinate for the origin of the vector window.

L_INT y

Y coordinate for the origin of the vector window.

L_INT nCx

The width of the vector window.

L_INT nCy

The height of the vector window.

Returns

Value Meaning
!NULL The function was successful and the return value is the window handle for the created control.
NULL An error ocurred and the window could not be created.

Comments

This function causes the class object to create the control window using the specified parameters.

This will fill in the m_hWnd data member with the handle to the new window.

If you call this function for a class object that already has a created window, the function will simply return m_hWnd.
