Change cmfcribbonbar height

Author: Wuhuan
Test environment: Windows XP
Development Environment: Visual Studio 2010

To change the height of cmfcribbonbar, You need to reload the calcfixedlayout function, for example:

Header file:

#pragma once//////////////////////////////////////////////////////////////////////////// CKofMFCRibbonQuickAccessToolBarclass CKofMFCRibbonQuickAccessToolBar : public CMFCRibbonQuickAccessToolBar{friend class CKofMFCRibbonBar;};//////////////////////////////////////////////////////////////////////////// CKofMFCRibbonBarclass CKofMFCRibbonBar : public CMFCRibbonBar{DECLARE_DYNAMIC(CKofMFCRibbonBar)public:CKofMFCRibbonBar(BOOL bReplaceFrameCaption = TRUE);virtual ~CKofMFCRibbonBar();protected:virtual CSize CalcFixedLayout(BOOL bStretch, BOOL bHorz);DECLARE_MESSAGE_MAP()};

Implementation file:

# Include "stdafx. H "# include" kofmfcribbonbar.

Cy; // height of the "classification" const int ncategoryheight = (m_dwhideflags & afx_ribbonbar_hide_elements )? 0: m_ncategoryheight; Cy = nquickaceestoolbarheight + ncategoryheight + max (m_ncaptionheight + m_ntabsheight, m_sizemainbutton.cy + nymargin);} If (afxglobaldata. dwmiscompositionenabled () {If (getparent ()-> iszoomed () & m_breplaceframecaption) {Cy + =: getsystemmetrics (sm_cysizeframe)-2 ;}} DC. selectObject (poldfont); Return csize (32767, CY );}

Modify the mainfrm. h file as follows:

#include "KofMFCRibbonBar.h"class CMainFrame : public CMDIFrameWndEx{//...protected: //CMFCRibbonBar m_wndRibbonBar;CKofMFCRibbonBar m_wndRibbonBar;}

In this way, the running result is as is, as shown in:

Now try to change the height and modify the above Code. The act of modifying 82 is as follows:

M_ncategoryheight = max (m_ncategoryheight, pcategory-> getmaxheight (& DC) + 80 );

Change 98 as follows:

Const int ncategoryheight = (m_dwhideflags & afx_ribbonbar_hide_elements )? 0: m_ncategoryheight + 20;

Re-compile and run, as shown in the following figure:
