Creating Popup Menus In Response to a Right-Button Click

Popup One of a Window's Menus

Add a Right-Button ListBox class or library to your project. Next add a rightbutton handler to the window containing your ListBox. The following boiler plate code for popup menu is all that is needed.

void MyWindow::EvRButtonDown (uint modKeys, TPoint& point)
{
    TDialog::EvRButtonDown(modKeys, point);

    // INSERT>> Your code here.
     TMenu menu(HWindow);
     HMENU hMenu = menu.GetSubMenu(0); // 0 is the first menu of this window, 
                                       // 1 would be the second etc.
     TPopupMenu popupMenu(hMenu); // Create the Menu
     GetCursorPos(point); // Put the menu at the click point
     popupMenu.TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON,point,0,HWindow);
}

When the user presses the right button, a menu will pop up in the current window and when the button is released, the command selected is executed.

Popup a Menu Created on The Fly

Sometimes you want to create a popup menu that is not one of those used by the window. the following example shows how to create such a menu. In this example, each of the cm commands must be defined as identifiers in the resource editor and must be tied to handlers in the response table.

void InventoryDlg::EvRButtonDown (uint modKeys, TPoint& point)
{
	 TDialog::EvRButtonDown(modKeys, point);

	 // INSERT>> Your code here.
	//::EvLButtonDblClk(modKeys, point);
	GetCursorPos(point);
	TPopupMenu rClickMenu;
	rClickMenu.AppendMenu(MF_STRING,CM_ORDER_ITEM,"&Order Item");
	rClickMenu.AppendMenu(MF_STRING,CM_PRICE_ITEM,"&Price Item");
	rClickMenu.AppendMenu(MF_STRING,CM_ADD_INVENTORY,"&Add Inventory");
	rClickMenu.AppendMenu(MF_STRING,CM_CHANGE_PRICE,"&Change Price");
	rClickMenu.AppendMenu(MF_SEPARATOR,0,(LPSTR)0);
	rClickMenu.AppendMenu(MF_STRING,CM_NEW_ITEM,"&New Item");
	rClickMenu.AppendMenu(MF_STRING,CM_DELETE_ITEM,"&Delete Item"); 
	rClickMenu.AppendMenu(MF_STRING,CM_LIST_REORDER,"List &Reorders");  
	rClickMenu.AppendMenu(MF_STRING,CM_FIND,"&Find");
	rClickMenu.TrackPopupMenu( TPM_LEFTALIGN | TPM_RIGHTBUTTON,point,0,*this);
}
