[英]Jpanels with Gridbaglayout inside a JPanel with GridbagLayout problems
I'm trying to get the CardLayout working correctly. 我正在尝试使CardLayout正常工作。 - I have the first "card" in my deck", which i've called firstPanel (Gridbaglayout). Inside that panel i want some other panels with the same layout (Gridbaglayout) which ofc has some components.
-我的甲板上有第一张“卡片”,我将其称为firstPanel(Gridbaglayout)。在该面板内,我需要其他具有相同布局(Gridbaglayout)的面板,其中包含一些组件。
as example under here - I'm showing one of the JPanels with Gridbaglayout that i want inside my firstPanel (Jpanel) called textFieldForPlayers. 作为此处下的示例-我展示了一个我希望在我的firstPanel(Jpanel)内部使用Gridbaglayout的JPanels,名为textFieldForPlayers。
I hope you understand what i mean. 我希望你明白我的意思。 if not i'll try to explain it more detailed.
如果没有,我将尝试更详细地解释。 :)

Picture 3 - This is what it looks like now 图片3-这是现在的样子
Picture 4 - Should be - 1 in the top, 2 in the middle and 3 in the bottom. 图片4-应该是-顶部1,中间2,底部3。 All of them centeret.
他们都是中心人物。
Your CardLayout, cl, is not behaving as a true CardLayout, suggesting something is wrong with code not shown. 您的CardLayout cl不能表现为真正的CardLayout,这表明未显示的代码有问题。 Myself, I try to modularize my gui creation, including using a separate utility method to help create gridbagconstraints if any complex constraints are needed.
我自己尝试将gui创建模块化,包括使用单独的实用程序方法来帮助创建gridbagconstraints(如果需要任何复杂的约束)。
For example: 例如:
import java.awt.BorderLayout;
import java.awt.CardLayout;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
import java.awt.event.ActionEvent;
import java.util.ArrayList;
import java.util.List;
import javax.swing.*;
import javax.swing.border.Border;

Like: 喜欢:
CardLayout cl = new CardLayout();
JPanel contentPane = new JPanel();
JPanel firstPanel = new JPanel();
JPanel secondPanel = new JPanel();
contentPane.setlayout(cl);
firstPanel.add(new JButton("1"));
secondPanel.add(new JButton("2"));
contentPane.add(firstPanel, "1");
contentPane.add(secondPanel, "2");
cl.show(contentPane, "1");
So now the contentPane contains 2 JPanels inside it. 因此,现在contentPane内部包含2个JPanels。 and now we would be seeing everything on firstPanel right?
现在我们将在firstPanel上看到所有内容,对不对? :)
