无法让自定义JPanel显示在JDialog上

Question

我开发了自己的属性类型数据结构，用于在应用程序中设置一些基本数据。我只是使用常规属性，但我希望用户能够编辑这些属性然后记录，显示顺序以及它们是否处于活动状态。此外，为了能够对不同的属性进行分组。

我创建了一个面板，显示属性并带有“编辑”按钮，以便他们实际进行更改。

然后另一个面板加载一个组并显示该组的所有属性。

这两个小组似乎都很好。然后，当我创建一个应该将所有组加载到每个面板中的JDialog时，我无法显示它。我玩弄了很多布局，没有运气。另外，我需要一个滚动窗格，所以当他们加班时。

我不太清楚在这一点上要做什么...如果我在面板上添加按钮，它会滚动得很好，所以我假设我想添加的面板有问题。

这是属性组类：

import java.util.LinkedHashMap;

public class SMoKEPropertyGroup {
private String name = null;
private String notes = null;
private int displayOrder = 0;
private boolean active = true;
private LinkedHashMap<String, SMoKEProperty> properties = new LinkedHashMap<>();

public SMoKEPropertyGroup(String name, String notes, int displayOrder, boolean active) {
    super();
    this.name = name;
    this.notes = notes;
    this.displayOrder = displayOrder;
    this.active = active;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getNotes() {
    return notes;
}

public void setNotes(String notes) {
    this.notes = notes;
}

public int getDisplayOrder() {
    return displayOrder;
}

public void setDisplayOrder(int displayOrder) {
    this.displayOrder = displayOrder;
}

public boolean isActive() {
    return active;
}

public void setActive(boolean active) {
    this.active = active;
}

public LinkedHashMap<String, SMoKEProperty> getProperties() {
    return properties;
}

public void addProperties(SMoKEProperty property) {
    this.properties.put(property.getName(), property);
}

}

这是实际的属性类：

public class SMoKEProperty {
private String groupName = null;
private String name = null;
private String value = null;
private String notes = null;
private int displayOrder = 0;
private boolean active = true;
private String displayableName = null;

public SMoKEProperty(String groupName, String name, String value, String notes, int displayOrder, boolean active) {
    super();
    this.groupName = groupName;
    this.name = name;
    this.value = value;
    this.notes = notes;
    this.displayOrder = displayOrder;
    this.active = active;
}

public String getGroupName() {
    return groupName;
}

public void setGroupName(String groupName) {
    this.groupName = groupName;
}

public String getName() {
    return name;
}

public String getDisplayableName() {
    return name;

}

public void setName(String name) {
    this.name = name;
}

public String getValue() {
    return value;
}

public void setValue(String value) {
    this.value = value;
}

public String getNotes() {
    return notes;
}

public void setNotes(String notes) {
    this.notes = notes;
}

public int getDisplayOrder() {
    return displayOrder;
}

public void setDisplayOrder(int displayOrder) {
    this.displayOrder = displayOrder;
}

public boolean isActive() {
    return active;
}

public void setActive(boolean active) {
    this.active = active;
}

@Override
public String toString() {
    return "SMoKEProperty \n" + "  groupName=" + groupName + "\ndisplayableName=" + getDisplayableName() + "\nname="
            + name + "\nvalue=" + value + "\nnotes=" + notes + "\ndisplayOrder=" + displayOrder + "\nactive="
            + active + "\n\n";
}

}
