Step 16

Handling Palette Changes

1.	Open the "Tutorial.h" file from the "File View" tab.

Right click "CMainFrame" and select "Properties".

From the "Properties" window toolbar, click on the Message icon.

Then click on the empty area beside the item " WM_QUERYNEWPALETTE" and choose OnQueryNewPalette

Replace the "return CMDIFrameWnd::OnQueryNewPalette();" statement with the following lines of code:

CMDIChildWnd* pMDIChildWnd = MDIGetActive();

   if (pMDIChildWnd!=NULL)
   {
      CView* pView = pMDIChildWnd->GetActiveView();

      if(pView!=NULL)

OnQueryNewPalette();

13.

Right click " CTutorialView" and select "Properties".

14.

19.	Open the "TutorialView.cpp" file from the "File View" tab and add the following line before the END_MESSAGE_MAP() statement:

ON_MESSAGE(WM_HANDLEPALETTE,OnHandlePalette)

20.	Now add the following lines of code to the end of the "TutorialView.cpp" file:

LRESULT CTutorialView::OnHandlePalette(WPARAM wParam, LPARAM lParam)
{
   if(lParam==TRUE)
   {
      if(m_RasterPntWnd.HandlePalette(WM_PALETTECHANGED, wParam, 0)==FALSE)
        m_RasterPntWnd.Repaint();
   }
   else
   {
      if(m_RasterPntWnd.HandlePalette(WM_QUERYNEWPALETTE, 0, 0)==FALSE)
