C# 中的垂直（仅）可调整大小的窗口窗体

发布于 2024-08-18 20:42:36 字数 75 浏览 7 评论 0原文

我遇到的情况是，允许用户调整窗口窗体的大小（但仅限垂直方向）对我来说是有益的。经过一番搜索，似乎关于这个特定主题的内容并不多。是否可以？

您需要将表单的 MinimumSize 和 MaximumSize 属性设置为高度不同但宽度相等的两种尺寸。

如果您根本不希望出现水平调整大小光标，则需要处理 WM_NCHITTEST 消息，如下所示：

protected override void WndProc(ref Message m) {
    base.WndProc(ref m);
    switch (m.Msg) {
        case 0x84: //WM_NCHITTEST
            var result = (HitTest)m.Result.ToInt32();
            if (result == HitTest.Left || result == HitTest.Right)
                m.Result = new IntPtr((int)HitTest.Caption);
            if (result == HitTest.TopLeft || result == HitTest.TopRight)
                m.Result = new IntPtr((int)HitTest.Top);
            if (result == HitTest.BottomLeft || result == HitTest.BottomRight)
                m.Result = new IntPtr((int)HitTest.Bottom);

            break;
    }
}
enum HitTest {
    Caption = 2,
    Transparent = -1,
    Nowhere = 0,
    Client = 1,
    Left = 10,
    Right = 11,
    Top = 12,
    TopLeft = 13,
    TopRight = 14,
    Bottom = 15,
    BottomLeft = 16,
    BottomRight = 17,
    Border = 18
}

You need to set the form's MinimumSize and MaximumSize properties to two sizes with different heights but equal widths.

If you don't want the horizontal resize cursor to appear at all, you'll need to handle the WM_NCHITTEST message, like this:

protected override void WndProc(ref Message m) {
    base.WndProc(ref m);
    switch (m.Msg) {
        case 0x84: //WM_NCHITTEST
            var result = (HitTest)m.Result.ToInt32();
            if (result == HitTest.Left || result == HitTest.Right)
                m.Result = new IntPtr((int)HitTest.Caption);
            if (result == HitTest.TopLeft || result == HitTest.TopRight)
                m.Result = new IntPtr((int)HitTest.Top);
            if (result == HitTest.BottomLeft || result == HitTest.BottomRight)
                m.Result = new IntPtr((int)HitTest.Bottom);

            break;
    }
}
enum HitTest {
    Caption = 2,
    Transparent = -1,
    Nowhere = 0,
    Client = 1,
    Left = 10,
    Right = 11,
    Top = 12,
    TopLeft = 13,
    TopRight = 14,
    Bottom = 15,
    BottomLeft = 16,
    BottomRight = 17,
    Border = 18
}

只是一个想法...

public partial class Form1 : Form {
    int _width;

    public Form1() {
        _width = this.Width;
        InitializeComponent();
    }

    protected override void OnResize(EventArgs e) {
        this.Width = _width;
        base.OnResize(e);
    }
}

编辑：请注意，最小/最大尺寸解决方案比这个 hack 工作得更好:)

Just an idea...

public partial class Form1 : Form {
    int _width;

    public Form1() {
        _width = this.Width;
        InitializeComponent();
    }

    protected override void OnResize(EventArgs e) {
        this.Width = _width;
        base.OnResize(e);
    }
}

EDIT: please note that the min/max size solutions work much better than this hack :)

设置最大和最小尺寸仅适用于表格的宽度。

将 FormBorderStyle 设置为 Ressized 并设置 MaximumSize 和 MaximumSize = new Size(this.Width, 0)

修正：

this.MinimumSize = new Size(this.Width, 0);
this.MaximumSize = new Size(this.Width, Int32.MaxValue);

Let the FormBorderStyle to Resizable and set MaximumSize and MinimumSize = new Size(this.Width, 0)

Correction:

this.MinimumSize = new Size(this.Width, 0);
this.MaximumSize = new Size(this.Width, Int32.MaxValue);

是的，这是可能的。只需设置 form.MinimumSize.Width = form.MaximumSize.Width = 100 （或任何你想要的宽度）。

为了避免 @orsogufo 解决方案的“橡皮筋”效果：

public Form1()
{
    InitializeComponent();
    this.MinimumSize = new Size(500, 0);
    this.MaximumSize = new Size(500, Screen.AllScreens.Max(s => s.Bounds.Height));
}

如果调整屏幕边界的大小，它不会正确调整其最大高度以适应更大的屏幕，但对于静态屏幕尺寸，它效果很好。

To avoid the "rubber-banding" effect of @orsogufo's solution:

public Form1()
{
    InitializeComponent();
    this.MinimumSize = new Size(500, 0);
    this.MaximumSize = new Size(500, Screen.AllScreens.Max(s => s.Bounds.Height));
}

It won't correctly adjust its maximum height to accommodate a larger screen if you resize the screen bounds, but for static screen sizes it works great.
