Windows窗体动态布局 [英] WIndows Forms dynamic layout

问题描述

我有一个自定义用户控件，可以执行我的应用程序.

I have a custom usercontrol which does the work of my app.

我需要一次在表单上拥有可变数量的用户控件，该数量在运行时是已知的.

I need to have a variable number of my usercontrols on my form at once, the number is known at runtime.

我希望每个窗口都具有完整的客户端宽度，并且所有控件都应填满窗口，大小相等，例如.如果有两个，则每个都是客户端高度的一半-如果三个，则每个都是客户端高度的三分之一.

I want each one to be full client width, and all controls to fill the window, equal size... eg. if there are two, then each are half the client height - if three, then each are one third of the client height.

并且布局应该随着主窗口的大小而调整大小.我不希望用户能够通过调整主窗口的大小来调整控件的大小(这样就可以拆分容器了)

And the layout should resize as the main window resizes. I don't want the user to be able to resize the controls other than by resizing the main window (so a split container is out)

我尝试使用TableLayoutPanel来执行此操作，但是当我将GrowStyle属性设置为TableLayoutPanelGrowStyle.AddRows并添加控件时，行数不会改变.

I've tried to use the TableLayoutPanel to do this but when I set the GrowStyle property to TableLayoutPanelGrowStyle.AddRows, and add my controls, the number of rows doesn't change.

当然，这种布局方案不难实现吗?我似乎无法弄清楚?

Surely this layout scheme isn't hard to achieve? I can't seem to figure it out?

谢谢

推荐答案

布局易于计算，然后很难使TLP获利.这是一种在设计器中效果很好的控件，但是在控件数量无法预测的情况下，它会很尴尬.

It the layout is simple to calculate then it gets to be pretty hard to make TLP pay off. Which is a control that works very well in the designer but is pretty awkward when you have an unpredictable number of controls.

这也可以很好地工作，减少了很多代码，也减少了控制UI速度的控制:

This will work fine as well, a lot less code and one less control to slow your UI down:

    protected override void OnResize(EventArgs e) {
        for (int ix = 0; ix < Controls.Count; ++ix) {
            int y1 = this.ClientSize.Height * ix / Controls.Count;
            int y2 = this.ClientSize.Height * (ix + 1) / Controls.Count;
            Controls[ix].Bounds = new Rectangle(0, y1, this.ClientSize.Width, y2-y1);
        }
        base.OnResize(e);
    }
    protected override void OnLoad(EventArgs e) {
        OnResize(e);
        base.OnLoad(e);
    }
