// 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 :-)
// if you want to reduce flickering, then you have to include
// the header of Keith Rule's CMemDC class in your .
// CToolBarEx will use it automagically then.
// If you want a "real cool" 3D look, then you have to exchange the call
// to "EnableDocking()" in your CMainFrame::OnCreate() method to
// "FrameEnableDocking()". This will ensure, that the toolbar has the
// same outfit as in Office or DevStudio.
//
// 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
// o Matthias Drigalla has pointed
// me out, that the timer is not released in all circumstances.
// o thanks to Jonathan Chin for his
// experiences with UNICODE and for his enhancement to conform to
// the standard interface (the flat toolbar should not perform any
// hit test (and hence displaying the raised button state) if the
// parent window (application) does not have the focus or is disabled.)
// o thanks to Wang Ruopeng (ripple@thinker.ep.tsinghua.edu.cn) for
// the enhanced outfit of checked buttons
//
// o Many thanks to Victor Vogelpoel, Jonathan Chin and Patrick Liechty
// for their help to test and correct some bugs in the enhanced version.
// Their work made this class much cleaner. Thanks.
//
// o Wolfgang Loch (W.Loch@intershop.de) sent in a fix for undockable bars
// o Thanks to John Armstrong (jarmstrong@runge.com.au) for his fix to
// the adjustment of gripperspace in "classic" mode
// o Thanks to Anatoly Ivasyuk (aivasyuk@clark.net) for a much cooler method
// to draw checked buttons that does not have the cursor on it.
//
//
// (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.
//
// 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:
// 05/10/98
// o buttons that are checked *and* disabled are now looking ok.
// o don't draw a gripper if the bar is not dockable
// o do not adjust space for gripper in "classic" mode
//
// 01/17/98
// o If you have Keith Rule's "MemDC.h" included via
// "stdafx.h", then CToolBarEx uses it to reduce
// flickering.
// o release the timer in all circumstances
// o made the class compile even if UNICODE is #define'ed
// o do not make any hit test (and display a raised button state)
// if the application does not have the focus.
// o Changed the outfit of a checked button that does not have
// the cursor on it.
// Major enhancements:
// o added easy way to add controls to a toolbar
// (both: replacing a button with a control and
// inserting/appending new controls)
// o Added many functions especially for the often
// requested need for additional controls
// o ALT-Drag feature implemented. You just can move buttons
// (and controls!) from one CToolBarEx-object to another
// in the style of the Developer Studio. There is no additional
// requirement for having this feature in your application.
// Just follow the online-help for how to enable customizable
// toolbars. CToolBarEx uses the same technique.
//
// 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

// 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, whether 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).
