- // ToolBarEx.cpp : implementation file
- //
- // Description:
- // CToolBarEx provides additional features to the standard toolbar
- // "CToolBar". The main addition is the flat mode (last seen in
- // Developer Studio 5.0).
- // There are no special requirements for having the flat mode in your
- // application (no special comctl32.dll or what ever)!
- // If you need custom draw abilities, then you have to use VC++ >= 4.2
- // However, the flat mode should work with older versions of VC++ too (let
- // me know of your experiences!)
- //
- // Usage:
- // The only task you have to perform, is to
- // #include "ToolBarEx.h"
- // in either StdAfx.h or MainFrm.h and to change the type of
- // CMainFrame::m_wndToolBar from CToolBar to CToolBarEx.
- // Don't forget to recompile :-)
- //
- // Acknowledgements:
- // o The main idea of how to draw a separator and the gripper is stolen
- // from Roger Onslow's MSIE flat toolbar.
- // Thanks for saving my time, Roger ;-)
- // o The embossed drawing of a disabled image came from
- // Victor M. Vogelpoel (victorv@telic.nl)
- // o Some hints for buttons with text came from
- // David Bates (bates@econ.ubc.ca)
- // (I'm still thinking, text on toolbar-buttons is broken.
- // That has to be tooltip's work. However, texts on buttons
- // now work)
- // o Thanks to Patrick Liechty (patrickl@code3.code3.com) for
- // the reports of his experiences with VC++ 4.0/4.1
- // o Thanks to Jeng-Yuan Sheu (m8501511@chu.edu.tw) for the
- // enhanced checked button.
- // o Thanks to Todd C. Wilson (todd@mediatec.com) for his
- // bug report and code-enhancement for users of VC++ 4.2b
- //
- //
- // (known) bugs and limitations:
- // o the CDRF_NEWFONT notification is still untested ...
- // o Assigning texts to buttons may cause the buttons to
- // resize horizontally without notified by CToolBar. This
- // leads to a wrong calculation inside CalcDynamicLayout()
- // and CalcFixedLayout(). One could override both these
- // functions in derived classes to avoid that problem,
- // but that would be a greater pain ...
- // o some features of the toolbars seen in Office97/DevStudio
- // are not implemented (for instance text-only buttons or
- // the way how image+text buttons are displayed. The Alt-drag
- // feature too is unimplemented)
- //
- // if you find others (and have a solution for them ?!), please let me know:
- // Joerg.Koenig@rhein-neckar.de (private site) or
- // J.Koenig@adg.de (company site)
- //
- // Changes:
- // 11/25/97
- // o Some minor modifications to compile with VC++ 4.0/4.1 and 4.2b
- // o checked buttons now look hilighted (as in Office97/DevStudio)
- //
- // 11/07/97
- // (2 minor bugs have been occured as a result of the last update :)
- // o The WRAP state of a separator will be ignored now, if
- // the bar is docked vertically
- // o Draw an image transparently. This is needed only if one
- // uses 256 color images.
- //
- // 10/30/97
- // o texts on buttons now work
- // o gripper improved for a closer look like Office97
- // o disabled images now look embossed
- // o a separator is drawn only if it has no WRAP state set

- #include "ToolBarEx.h"

- // local helper class CCustomDrawInfo
- //
- // The helper class CCustomDrawInfo handles the messaging to the docking
- // frame of the toolbar in flat mode only. If flat-mode is disabled, then
- // MFC's own messanger will be used.
- //
- // A few words about custom draw on toolbars:
- // o custom draw is possible for MFC >= 4.2 only (older versions don't know
- // anything about certain structures ...)
- // o MFC does not set the "rc" member of NMCUSTOMDRAW to the rectangle of the
- // button that will be drawn. However, we do, so watch out, wether the
- // toolbar is flat or not (or ignore the "rc" member in both cases).
- // If the current mode is not "flat", then MFC's art of message arrives ...
- // o MFC does not send a message for separators, so we too don't do it.
- // o It seems that MFC toolbars never send *ERASE notifications; instead they
- // send TBN_QUERYDELETE for instance.
- // o The CDRF_NEWFONT notification result is ignored (in flat mode. Never
- // tried with original MFC, because it is broken on toolbars).
