Java:强制组件填充GridLayout中的整个行 [英] Java: forcing a component to fill up the entire row in a GridLayout

问题描述

我正在编写一个程序，该程序允许多个用户共享屏幕截图.每次用户连接时，参与房间"的每个人(一群可以互相接收屏幕截图的用户)都可以看到用户拍摄的屏幕截图.为了能够看到屏幕截图，框架需要自行拆分，以便为该用户的屏幕截图留出专用空间.

I am writing a program that allows multiple users the share screenshots. Every time a user connects, everyone who is participating in the "room" (a bunch of users that are able to receive screen shots from one another) becomes able to see a screen shot that the user takes. To be able to see the screen shot, the frame needs to split itself up so that there is a dedicated space for that user's screen shots.

我决定使用GridLayout，因为它会将组件拆分成相等大小的矩形，这正是我想要的.布局完全符合我的需要，除了一个问题.如果我的GridLayout配置为有两行和两列，那么即使只有一个组件，最底下的行仍会分为两列.这是预期的行为，但是有没有解决的办法，最好不要使用其他布局?我真的很喜欢GridLayout的简单性.我已经考虑过使用BorderLayout，但是它有局限性，因为我可以放置项目的空间一定.

I decided to use a GridLayout because it splits components into equally-sized rectangles which is what I am looking for. The layout does exactly what I need it to, except there is one problem. If I my GridLayout configured that there are two rows and columns, the bottom-most row will still be split into two columns, even when there is only a single component. This is expected behavior, but is there a walk-around, preferably without using a different layout? I really like the simplicity of GridLayout. I have considered using a BorderLayout, but it is limited because there is a set amount of spaces where I can place items.

不支持图片格式，因此我无法将其嵌入此问题. 这是框架看起来像已满的样子.我将实际的屏幕截图替换为按钮，因为我只是在测试.

现在，这是我从最底部的行中删除按钮时的外观: http://cl.ly/2j3Z0V1r3w1S3F160j05 /Screen%20shot%202012-05-13%20at%204.23.41%20PM.png

这是我希望最底部的行显示的样子: http://cl.ly/0J2R2y2L06151F0k0Y0i /Screen%20shot%202012-05-13%20at%204.24.11%20PM.png

The format of the pictures wasn't supported, so I could not embed them into this question. Here is how the frame looks like it is full. I substituted the actual screen shots for buttons because I am just testing.

Now here is how it looks when I remove a button from the bottom-most row: http://cl.ly/2j3Z0V1r3w1S3F160j05/Screen%20shot%202012-05-13%20at%204.23.41%20PM.png

Here is how I would want the bottom-most row to look: http://cl.ly/0J2R2y2L06151F0k0Y0i/Screen%20shot%202012-05-13%20at%204.24.11%20PM.png

如何使最底部的行看起来像这样?请记住，我仍然希望其他行具有两列，但我只希望最底部的一行具有一列.

谢谢！

How can I make the bottom-most row look like that? Keep in mind I still want the other rows to have two columns, but I only want the bottom-most one to have one column.

Thanks!

推荐答案

我决定采用略有不同的方法.由于在屏幕数量均匀的情况下，使用GridLayout可以很好地布局单独的屏幕，因此，如果屏幕数量 个，我决定将屏幕简单地分成几页.

I decided to go with a slightly different approach. Since the separate screens are laid out really nicely using GridLayout when there are an even amount of screens, I decided to simply split up the screens into pages if there is an odd amount of screens.
