Question

我正在尝试在List<MyDO> processedList = new ArrayList<>(dataList.size()); for(int i = 0, num = dataList.size(); i < num; i++) { if(...) { // your filter criteria MyDO myDO = dataList.get(i); try { ...// some error at i } catch(Exception ex) { throw new IllegalStateException("at index "+i, ex); } processedList.add(myDO); } }中创建一个程序。但是，我不知道如何调用我的List<MyDO> processedList = new ArrayList<>(dataList.size()); for(int i = 0, num = dataList.size(); i < num; i++) { if(...) { // your filter criteria MyDO myDO = dataList.get(i); try { ...// some error at i } catch(Exception ex) { logger.error("Invalid data found at "+i); break; } processedList.add(myDO); } }值来驱动代码后面要执行的操作数量（尚未编写）。

代码末尾的类Gtk3+是我将根据在Gtk.SpinButton中输入的数字执行命令的地方。现在，我已经留下了一个简单的打印命令，以便可以告诉我代码何时可以正常工作。

很抱歉，如果我共享太多代码，我不知道在不共享所有代码的情况下如何正确显示我的问题。

initiate()

我想要的结果是将要输入到gtk.spinbutton中的数字也打印在终端上。相反，我得到了：

                area = self.get_content_area()
                area.add(Gtk.Label("Running..."))
                self.show_all()

                initiate()

class initiate(MainWindow):

        def __init__(self):
                self.var1 = MainWindow()
                num = int(self.var1.numfiles)
                print (numfiles)

window = MainWindow()
window.connect("delete-event", Gtk.main_quit)
window.show_all()
Gtk.main()

Python3：无法获取Gtk.SpinButton值
