具有可切换组头的JList [英] JList with toggable group headers
问题描述
是否可以在Java中执行以下图像?
Is it possible to do something like the following image in Java?
我了解到，为了显示每个列表元素的图像，我需要使用带有自定义单元格渲染器的多列列表.但是我的问题是要对列表元素进行分组，并使用组标题...
I understand that I would need to be using a multi columned list, with a custom cell renderer, in order to show the images of each list element. But my question is regards to Grouping the list elements, and using group headers...
如上图所示，它来自Windows资源管理器，正是我要在Java中使用JList执行的分组列表视图的类型.
As you can see from the image above this comes from windows explorer and is exactly the type of grouped list view that I would be looking to do with a JList in Java.
推荐答案
在这种情况下，我不认为我会使用JTable.
I don't think I would use a JTable in this situation.
首先，我将使用简单的JPanel和 DesignGridLayout 在 DesignGridLayout摊牌应用程序的"动态布局"部分，例如"示例4-缩进行相同".
First of all, I'd use a simple JPanel with DesignGridLayout, something like the example demonstrated in DesignGridLayout showdown application, section "Dynamic Layouts", example "Example 4 - Same with indented rows".
在该示例中，您必须更改用于轮廓效果的图标(在示例中为三角形，而不是人字形).
In that example you'd have to change the icons used for the outline effect (triangles instead of chevrons in the example).
然后，我将创建一个从JPanel派生的DrivePane，其中将包含驱动器图标作为JLabel(无文本)，将驱动器名称包含为JLabel，大小包含为JLabel.我可能会将GridBagLayout用作DrivePane的LayoutManager.该组件将用于显示的每个驱动器.
Then, I would create a DrivePane deriving from JPanel, that would contain the drive icon as a JLabel (with no text), the drive name as a JLabel, the size as a JProgress bar, the size as a JLabel. I would probably use GridBagLayout as the LayoutManager for DrivePane. That component would be used for every drive to show.
