#include "..\..\..\..\..\Include\ClassLib\ltWrappr.h"
|
f. |
Add the following define statement after #define VC_EXTRALEAN (keep in mind, you need to change the XX to your current LEADTOOLS version): |
#define LTVXX_CONFIG

{
m_pAutomation = pAutomation;
}
L_VOID CBitmapWindow::SetToolBar(LAnnToolBar * pToolBar)
{
m_pToolBar = pToolBar;
}
L_VOID CBitmapWindow::OnDraw (HDC hdc, RECT & Rect)
{
LBitmapWindow::OnDraw(hdc, Rect);
L_INT nRet;
if (m_pContainer != NULL)
{
nRet = m_pContainer->Draw(hdc, &Rect);
}
}
LRESULT CBitmapWindow::MsgProcCallBack(HWND hWnd,UINT uMsg,WPARAM wParam,LPARAM lParam)
{
switch (uMsg)
{
case WM_LTANNEVENT:
if(m_pAutomation != NULL)
{
int uChecked = m_pToolBar->GetToolChecked() ;
m_pAutomation->SetTool(uChecked);
}
break;
};
return LBitmapWindow::MsgProcCallBack(hWnd,uMsg,wParam,lParam);
}
16. | Create a new file called Imports.cpp and place it in Source Files folder in your project. | |
a. | From the main menu, select File -> New. | |
b. | Select C++ Source File in the Files tab. | |
c. | Make sure that Add to project: checkbox is checked, and type Imports.cpp in the File name: edit box, then click OK. |
