wxpython：'示例'对象没有属性'OnClick'

我正在使用wxpython制作元素周期表的GUI，我添加了所有按钮。所以现在我想要的是当用户选择多个按钮时，它应该给我输出与按钮上标记的相同。试图运行此代码，但得到错误。不知道出了什么问题，我在这里做。

    public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

    Intent intent1 = new Intent(context, MainActivity.class);
    intent1.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    PendingIntent pendingIntent = PendingIntent.getActivity(context, 100, intent1, PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder builder = (NotificationCompat.Builder) new NotificationCompat.Builder(context)
            .setSmallIcon(R.drawable.ic_stat_name)
            .setContentIntent(pendingIntent)
            .setContentText("notification text")
            .setContentTitle("notification title")
            .setAutoCancel(true)
            .setOngoing(true);
    notificationManager.notify(100, builder.build());

}

2 个答案:

答案 0 :(得分：0)

好吧，self.Bind(wx.EVT_BUTTON, self.OnClick, a)中的第三个参数似乎没用，请尝试self.Bind(wx.EVT_BUTTON, self.OnClick)

（与wxformbuilder生成的代码比较）

答案 1 :(得分：0)

考虑到按钮的数量，这一切都有点紧张，你必须将按钮声明为面板的一部分，而不是希望sizer能为你完成工作。
几乎没有变化，但它们很重要。

代码现在包含用于元素显示的元素{dictionary}（我错过了一些像Oganesson这样的稀有元素，但如果你不能吃它，吸烟，用它购买或用它来扩展山，谁在乎？）
