Hello,
Im trying to disable the d&d support from the win32_test, following the
instructions from the faq. To do so, in createwindow, after the call to
baseWindow->Create, I stuck the following code :
rv = baseWindow->Create();
if (NS_FAILED(rv)) {
printf("Create\n");
}
<here>
/* Drag and drop */
nsCOMPtr<nsICommandManager> CommandManager =
do_GetInterface(mPrivate->webBrowser);
if (CommandManager)
{
nsCOMPtr<nsIDOMWindow> theDOMWindow =
do_GetInterface(mPrivate->webBrowser);
nsCOMPtr<nsICommandParams> cmdParamsObj =
do_CreateInstance(NS_COMMAND_PARAMS_CONTRACTID,&rv);
nsISupports *tmp;
tmp = (nsISupports *)mPrivate->chrome;
cmdParamsObj->SetISupportsValue("addhook", tmp ); //
reinterpret_cast<nsISupports*>(mPrivate->chrome) returns an error
CommandManager->DoCommand("cmd_clipboardDragDropHook",
cmdParamsObj, theDOMWindow);
}
I also modified the WebBrowserChrome so that it implements
nsIClipboardDragDropHooks and provided a default implementation for every
method of nsIClipboardDragDropHooks.
In particular changed NS_IMPL_ISUPPORTS5 ( ... ) into
NS_IMPL_ISUPPORTS6(WebBrowserChrome,
nsIWebBrowserChrome,
nsIInterfaceRequestor,
nsIEmbeddingSiteWindow,
nsIClipboardDragDropHooks,
nsIWebProgressListener,
nsISupportsWeakReference )
At execution, the interface is never requested, and its methods never
called.
Any hint appreciated .
TIA.
Philippe.
