xpcom - 我可以在 Thunderbird 扩展中挂钩回复事件吗

Question

有没有办法在用户单击“回复”时触发的 Thunderbird 扩展中添加事件处理程序？

Answer 1

在 compose_overlay.js 中：

window.addEventListener("compose-send-message", mySendHandler, true);
window.addEventListener("compose-window-init", myReplyHandler, true);

function mySendHandler(evt){
    var msgcomposeWindow = document.getElementById( "msgcomposeWindow" );
    var msg_type = msgcomposeWindow.getAttribute( "msgtype" );

    // do not continue unless this is an actual send event
    if(!(msg_type == nsIMsgCompDeliverMode.Now || msg_type == nsIMsgCompDeliverMode.Later) )
        return;

    //do not continue unless it is a reply action (not a forward)
    var msgType = gMsgCompose.type;
    if(!(msgType == Components.interfaces.nsIMsgCompType.ReplyToSender || msgType == Components.interfaces.nsIMsgCompType.Reply))
        return;

    var origURI = gMsgCompose.originalMsgURI;
    if(origURI == ""){
        return;
    }

    var TBmain = Components.classes["@mozilla.org/appshell/window-mediator;1"].getService().QueryInterface(Components.interfaces.nsIWindowMediator).getMostRecentWindow("mail:3pane");
    var msgHdr = TBmain.messenger.messageServiceFromURI(origURI).messageURIToMsgHdr(origURI);

    //TODO
    //Do something with the msgHdr

}

function myReplyHandler(evt){
    var origURI = gMsgCompose.originalMsgURI;
    var TBmain = Components.classes["@mozilla.org/appshell/window-mediator;1"].getService().QueryInterface(Components.interfaces.nsIWindowMediator).getMostRecentWindow("mail:3pane");
    var msgHdr = TBmain.messenger.messageServiceFromURI(origURI).messageURIToMsgHdr(origURI); 

    //TODO
    //Do something with the msgHdr
}

根据您的目标，您可以覆盖回复按钮并在用户单击回复按钮时获得点击事件。
