如题

[akinge]

void CMyView::OnRButtonDown(UINT nFlags, CPoint point)
{
CView::OnRButtonDown(nFlags, point);

CMenu* menu_bar = AfxGetMainWnd()->GetMenu();
CMenu* file_menu = menu_bar->GetSubMenu(0);
ASSERT(file_menu);

file_menu->TrackPopupMenu(TPM_LEFTALIGN |TPM_RIGHTBUTTON, point.x,
point.y, this);
}

这个我知,问题是我要用户只在那个toolbar范围内右键单击才显示这个菜单,除此以外不显示.我想添加CToolBar的鼠标单击事件,但是怎么添加呢??

是不是可以继承CToolBar类，然后在该类中自己处理右键点击的消息.

To implement a drop-down button

Once your CToolBarCtrl object has been created, set the TBSTYLE_EX_DRAWDDARROWS style, using the following code:
m_wndToolBar.GetToolBarCtrl().SetExtendedStyle(TBSTYLE_EX_DRAWDDARROWS);

Set the TBSTYLE_DROPDOWN style for any new (InsertButton orAddButtons) or existing (SetButtonInfo) buttons that will be drop-down buttons. The following example demonstrates modifying an existing button in a CToolBarCtrl object:
TBBUTTONINFO tbi;

tbi.dwMask= TBIF_STYLE;
tbi.cbSize= sizeof(TBBUTTONINFO);
m_wndToolBar.GetToolBarCtrl().GetButtonInfo(ID_EDIT_CUT, &tbi);
tbi.fsStyle |= TBSTYLE_DROPDOWN;
m_wndToolBar.GetToolBarCtrl().SetButtonInfo(ID_EDIT_CUT, &tbi);

Add a WM_NOTIFY handler to the parent class of the toolbar object.


In the new handler, check for the TBN_DROPDOWN notification, using the following code:
#define lpnm ((LPNMHDR)lParam)
#define lpnmTB ((LPNMTOOLBAR)lParam)

switch(lpnm->code)
{
case TBN_DROPDOWN:
//drop down button was hit
//handle appropriately
. . .
return FALSE; //indicates the TBN_DROPDOWN
//notification was handled.
}

If the TBN_DROPDOWN notification has been sent, display the appropriate popup menu. The following code demonstrates one method:
CMenu menu;
VERIFY(menu.LoadMenu(IDR_MENU1));
CMenu* pPopup = menu.GetSubMenu(0);
ASSERT(pPopup != NULL);
pPopup->TrackPopupMenu(TPM_RIGHTALIGN |
TPM_RIGHTBUTTON, x, y, this);
