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 <stdafx.h>. // 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 <matthias.drigalla@bluewin.ch> has pointed // me out, that the timer is not released in all circumstances. // o thanks to Jonathan Chin <jonathan.chin@scitec.com.au> 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 #include "stdafx.h" #include "ToolBarEx.h" #ifndef __AFXPRIV_H__ #include <afxpriv.h> // one of the most interesting headers ;-) // if you plan to change CToolBarEx, then you // should better insert it in your "stdafx.h" // to speed up compilation #endif #ifdef _MEMDC_H_ //#undef _MEMDC_H_ // this is for testing purposes #endif #ifdef _DEBUG #define new DEBUG_NEW #undef THIS_FILE static char THIS_FILE[] = __FILE__; #endif ///////////////////////////////////////////////////////////////////////////// // 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, whet
