Jython Swing超级呼叫将类“扩展"设置为“扩展". JTextField [英] Jython swing supercall to class "extending" JTextField

问题描述

我正在尝试创建类似于此处的面板.但是，如果我尝试为某些方法调用super，它将进入无限递归，从而导致递归限制(对于stackoverflow从来没有更合适的问题；))，这些方法例如是paint和add(我尝试过的这两个方法，我想这都是继承的东西.

I am trying to make a custom TextField similar to the panel here. However if I try calling super for certain methods it goes into infinite recursion leading to the recursion limit (never had a more suiting question for stackoverflow ;) ), the methods are for example paint and add (those two I tried, I guess it is everything inherited).

以下是重要的代码摘录:

Here is the important code excerpt:

class inputWithButtons(JLayeredPane):
    def __init__(self):
        self.setLayout(_textFieldWithButtons())

        self._fileField = JTextField()
        self.add(self._fileField, Integer(1))
        self.preferredSize = (0, 40) #TODO: why does minimumSize not work?



    def add(self, component, layer):  #recurses indefinitly
        super(inputWithButtons, self).add(component, layer)
        self.revalidate()

推荐答案

如果该方法在各自的java类中受保护，则必须使用以下语法(老实讨厌此方法)

If the method is protected in their respective java class, you have to use the following syntax (Honestly hate this method)

self.super__

例如:

from javax.swing import JPanel

class panel(JPanel):
    def paintComponent(self, graphic):
        self.super__paintComponent(graphic)
        # Do something

来源

要调用任何其他超类方法，请使用以下语法:

To call any other super class methods, you use this syntax:

SuperClassName.method(self, *args)

使用新样式类:

super(panel, self).method(*args)
