This code was contributed by <A HREF="mailto:Girish_Bharadwaj@smtpnotes.pictel.com">Girish Bharadwaj</A>.
<p><b>CCustomMenu:</b> This class is the owner drawn version of the CMenu. You will
be able to
<ol>
<li>Set the Text Color.
<li>Set the highlight color
<li>Set the Highlight Style.
<li>Set the selected and normal Icon for the Menu item.
<li>Set the Icon size.
</ol>
<p>In order to use it, you need to create MENUDATA stuctrure and fill it with
the text and the selected and normal Icon IDs for each menu item. Then, you
have to pass the pointer to that structure via the LPCTSTR argument of the
AppendMenu or the InsertMenu. This is how the code snippet using this looks
like. The following are declared as the class members so that they can stay till
the class is present.
<p>In the .H file of the containing class
<PRE><TT><FONT COLOR="#990000"> CCustomMenu m_cCustomMenu;
MENUDATA menuData [8]; // as many menu items are present , You should be able to use
//new and do the same
</FONT></TT></PRE>
<p>In the .CPP file of the class where you want to use the menu
<PRE><TT><FONT COLOR="#990000"> m_customMenu.CreateMenu ();
m_customMenu.SetIconSize (25,25); //This is to set the size of the Icon.
// This should be used only once for any menu
// in order to resize it, destroy and create the menu again with different size.
m_customMenu.SetHighlightStyle (Normal); //Or TextOnly, if you want the
// background color to remain the same
// and the Text color to change to the Highlight color.
</FONT></TT></PRE>
<p>The following setXXXColor sets the menu colors. If you dont want to
change any, Dont call these member functions.
<PRE><TT><FONT COLOR="#990000"> m_customMenu.SetTextColor (RGB (255,0,0));
m_customMenu.SetBackColor (RGB (255,255,255));
m_customMenu.SetHighlightColor (RGB (0,0,255));
lstrcpy (menuData[0].menuText , "text1");
menuData[0].menuIconNormal= IDI_ICON1;
m_customMenu.AppendMenu (MF_OWNERDRAW,3,(LPCTSTR)menuData);
</FONT></TT></PRE>
<p>Do this for each menu item. For the Popup menu items, this will not work
since, the 2nd argument of AppendMenu is actually a HMENU instead of the
ID. So, for that particular case, Store the HMENU which you pass in the 2
argument and Handle OnMeasureItem for the main window class and do the
following:
<PRE><TT><FONT COLOR="#990000">void CMyView::OnMeasureItem(int nIDCtl, LPMEASUREITEMSTRUCT lpMeasureItemStruct)
{
if ( lpMeasureItemStruct->CtlType == ODT_MENU &&
IsMenu((HMENU)lpMeasureItemStruct->itemID) &&
(lpMeasureItemStruct->itemID == (UINT)m_hMenuSub) )
{
m_customMenu.MeasureItem (lpMeasureItemStruct);
}
else
// let MFC's self-drawing handle it
CView::OnMeasureItem(nIDCtl, lpMeasureItemStruct);
}
</FONT></TT></PRE>
The following are the member functions you can use to customize your Menu:
(names are pretty self explanatory).
<PRE><TT><FONT COLOR="#990000"> void SetTextColor (COLORREF );
void SetBackColor (COLORREF);
void SetHighlightColor (COLORREF);
