对接多个控件-一个可填充剩余空间 [英] Docking multiple controls - one fills remaining space

问题描述

我正在尝试将N个控件停靠在一个容器中.我希望它们全部填满整个宽度，但要堆叠.我希望一个特定的控件(当前是最后一个)填充剩余的空间，而所有其他控件的大小都固定.

此:

  Button b1 = new Button(){文本="Button 1"，Dock = DockStyle.Top};按钮b2 = new Button(){文本=按钮2"，Dock = DockStyle.Top};按钮b3 = new Button(){文本=按钮3"，Dock = DockStyle.Fill};Controls.Add(b1);Controls.Add(b2);Controls.Add(b3); 

产生这个:

如您所见，Button 3完全按照我的指示执行: Fill 父级.但这不是我想要要做的.除了手动放置和处理调整大小事件等以外，如何使Button 3填充剩余空间?

注意:我不是使用设计器.

解决方案

在添加 b3.BringToFront()(将其添加到 Controls 之后)的同时，这里最简单的解决方案是简单地更改将按钮添加到 Controls 的顺序.以下代码可以完美运行:

  Button b1 = new Button(){文本="Button 1"，Dock = DockStyle.Top};按钮b2 = new Button(){文本=按钮2"，Dock = DockStyle.Top};按钮b3 = new Button(){文本=按钮3"，Dock = DockStyle.Fill};Controls.Add(b3);//这个家伙先！Controls.Add(b1);Controls.Add(b2); 

结果:

如果您仔细看一下这个小示例中的边框，它实际上比 BringToFront()效果更好.

I'm trying to dock N number of controls in a container. I want them all to fill the entire width, but stack. I want one particular control (currently the last one) to fill the remaining space, while all others have fixed sizes.

This:

Button b1 = new Button() { Text = "Button 1", Dock = DockStyle.Top };
Button b2 = new Button() { Text = "Button 2", Dock = DockStyle.Top };
Button b3 = new Button() { Text = "Button 3", Dock = DockStyle.Fill };

Controls.Add(b1);
Controls.Add(b2);
Controls.Add(b3);

Produces this:

As you can see, Button 3 is doing exactly what I told it to: Fill the parent. But that's not what I want it to do. Aside from manually placing, and handling resize events, etc. how can I make Button 3 fill the remaining space?

Note: I am not using the designer.

解决方案

While adding b3.BringToFront() (after it has been added to Controls) works, the simplest solution here, is to simply change the order in which the buttons are added to Controls. The following code works perfectly:

Button b1 = new Button() { Text = "Button 1", Dock = DockStyle.Top };
Button b2 = new Button() { Text = "Button 2", Dock = DockStyle.Top };
Button b3 = new Button() { Text = "Button 3", Dock = DockStyle.Fill };

Controls.Add(b3);    // this guy first!
Controls.Add(b1);
Controls.Add(b2);

The result:

If you take a close look at the borders in this little example, this actually seems to work better than BringToFront().
