some specific way to realize it?
Yes, you're right.
In my code this is done in such a way:
.h
class CBrowserWnd : *many public base classes, and among them:* public
nsIWebProgressListener
{
//many NS_DECL_* and among them:
NS_DECL_NSIWEBPROGRESSLISTENER //this macro contains declarations
for methods from nsIWebProgressListener, no need to type them manyally
};
.cpp
NS_IMPL_ADDREF(CBrowserWnd)
NS_IMPL_RELEASE(CBrowserWnd)
NS_INTERFACE_MAP_BEGIN(CBrowserWnd)
//many NS_INTERFACE_MAP_ENTRY and some
NS_INTERFACE_MAP_ENTRY_AMBIGUOUS
NS_INTERFACE_MAP_ENTRY(nsIWebProgressListener)
NS_INTERFACE_MAP_END
//and later in the same .cpp the implementation of 5 methods of
nsIWebProgressListener:
NS_IMETHODIMP CBrowserWnd::OnProgressChange(nsIWebProgress *progress,
nsIRequest *request,
PRInt32
curSelfProgress, PRInt32 maxSelfProgress,
PRInt32
curTotalProgress, PRInt32 maxTotalProgress)
{
//some code
}
NS_IMETHODIMP CBrowserWnd::OnStateChange ( nsIWebProgress *progress,
nsIRequest *request, PRUint32 progressStateFlags, nsresult status )
{
//some code
}
NS_IMETHODIMP CBrowserWnd::OnLocationChange ( nsIWebProgress*
aWebProgress, nsIRequest* aRequest, nsIURI *location )
{
//the code from my prev. message
}
NS_IMETHODIMP CBrowserWnd::OnStatusChange ( nsIWebProgress*
aWebProgress, nsIRequest* aRequest, nsresult aStatus, const PRUnichar*
aMessage )
{
return NS_OK;
}
NS_IMETHODIMP CBrowserWnd::OnSecurityChange ( nsIWebProgress
*aWebProgress, nsIRequest *aRequest, PRUint32 state )
{
return NS_OK;
}
