为按钮添加消息响应，不成功，求指导啊！

Question

在工具栏创建了一个按钮，添加了消息响应，但是按钮还是灰色的。
BEGIN_MESSAGE_MAP(CPropertiesWnd, CDockablePane)
          
ON_BN_CLICKED(1,OnIcon1)
END_MESSAGE_MAP()
if (!m_wndObjectButton.Create(_T("My button"), WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON, rectDummy, this, 1))
{
TRACE0("未能创建属性组合 \n");
return -1;      // 未能创建
}之后按钮还是不可用。button

Answer 1

class CWorkspaceToolBar : public CMFCToolBar
{
public: 
// All commands should be routed via owner window, not via frame:
virtual void OnUpdateCmdUI(CFrameWnd* /*pTarget*/, BOOL bDisableIfNoHndler) 
{ 
CMFCToolBar::OnUpdateCmdUI ((CFrameWnd*) GetOwner (), bDisableIfNoHndler);
}// Toolbar should't appear on the customization list
virtual BOOL AllowShowOnList () const  { return FALSE; }
virtual void AdjustLayout ();
};
在CDockablePane头文件里添加： 
CWorkspaceToolBar m_wndToolBar;
在CDockablePane的OnCreate里添加// Create toolbar:
if (!m_wndToolBar.Create (this, AFX_DEFAULT_TOOLBAR_STYLE, AFX_IDW_TOOLBAR + 1) ||
!m_wndToolBar.LoadToolBar(IDR_WORKSPACE_TOOLBAR, 0, 0, TRUE /* Is locked */))
{
TRACE0("Failed to create toolbar\n");
return -1; // fail to create
}m_wndToolBar.SetPaneStyle(m_wndToolBar.GetPaneStyle() |
CBRS_TOOLTIPS | CBRS_FLYBY);m_wndToolBar.SetPaneStyle (
m_wndToolBar.GetPaneStyle () & 
~(CBRS_GRIPPER | CBRS_SIZE_DYNAMIC | CBRS_BORDER_TOP | CBRS_BORDER_BOTTOM | CBRS_BORDER_LEFT | CBRS_BORDER_RIGHT));m_wndToolBar.SetOwner (this);// All commands will be routed via this control , not via the parent frame:
m_wndToolBar.SetRouteCommandsViaFrame (FALSE);

void CXXX::UpdateControls(BOOL bEnabled)
{
    for(int i = 0, j = GetToolBarCtrl().GetButtonCount(); i < j; i++)
    {
        if(GetButtonStyle(i)&(TBBS_SEPARATOR))
            continue;
 
        if(bEnabled)
            SetButtonStyle(i, GetButtonStyle(i)&(~TBBS_DISABLED));
        else
            SetButtonStyle(i, GetButtonStyle(i)|TBBS_DISABLED);
    }
 
    RedrawWindow();
}
