AutoSizeMode 枚举

定义

命名空间:

System.Windows.Forms

程序集:

System.Windows.Forms.dll

指定启用控件的 AutoSize 属性时该控件的行为。

public enum class AutoSizeMode

public enum AutoSizeMode

type AutoSizeMode = 

Public Enum AutoSizeMode

继承

Object

ValueType

Enum

AutoSizeMode

字段

GrowAndShrink	0	控件根据它的内容增大或缩小。 不能手动调整该控件的大小。
GrowOnly	1	控件可以根据其内容任意增大，但不会缩小至小于它的 Size 属性值。 窗体可以调整大小，但不能缩小到它所包含的任意控件被隐藏。

示例

下面的代码示例显示了使用代码创建的窗体，该表单会自动调整大小以适应其内容。 运行后，窗体将显示一个 Label、一个 TextBox 用于输入 URL 和一个 Button 用于在用户的默认 Web 浏览器内显示该 URL。 代码示例使用 a 一 FlowLayoutPanel 个来布局包含的控件，并设置 AutoSize 并 AutoSizeMode 增大和缩小以适应其形式的内容。

private void Form1_Load(object sender, EventArgs e)
{
    this.AutoSize = true;
    this.AutoSizeMode = AutoSizeMode.GrowAndShrink;
    this.Text = "URL Opener";

    flowPanel = new FlowLayoutPanel();
    flowPanel.AutoSize = true;
    flowPanel.AutoSizeMode = AutoSizeMode.GrowAndShrink;
    this.Controls.Add(flowPanel);

    urlLabel = new Label();
    urlLabel.Name = "urlLabel";
    urlLabel.Text = "URL:";
    urlLabel.Width = 50;
    urlLabel.TextAlign = ContentAlignment.MiddleCenter;
    flowPanel.Controls.Add(urlLabel);

    urlTextBox = new TextBox();
    urlTextBox.Name = "urlTextBox";
    urlTextBox.Width = 250;
    flowPanel.Controls.Add(urlTextBox);

    urlButton = new Button();
    urlButton.Name = "urlButton";
    urlButton.Text = "Open URL in Browser";
    urlButton.Click += new EventHandler(urlButton_Click);
    flowPanel.Controls.Add(urlButton);
}

void urlButton_Click(object sender, EventArgs e)
{
    try
    {
        Uri newUri = new Uri(urlTextBox.Text);
    }
    catch (UriFormatException uriEx)
    {
        MessageBox.Show("Sorry, your URL is malformed. Try again. Error: " + uriEx.Message);
        urlTextBox.ForeColor = Color.Red;
        return;
    }
    
    // Valid URI. Reset any previous error color, and launch the URL in the 
    // default browser.
    // NOTE: Depending on the user's settings, this method of starting the
    // browser may use an existing window in an existing Web browser process.
    // To get around this, start up a specific browser instance instead using one of
    // the overloads for Process.Start. You can examine the registry to find the
    // current default browser and launch that, or hard-code a specific browser.
    urlTextBox.ForeColor = Color.Black;
    Process.Start(urlTextBox.Text);
}

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Me.AutoSize = True

    urlLabel.Width = 50
    urlLabel.TextAlign = ContentAlignment.MiddleCenter
    flowPanel.Controls.Add(urlLabel)

    urlTextBox = New TextBox()

    urlTextBox.Width = 250
    flowPanel.Controls.Add(urlTextBox)

    urlButton = New Button()
    urlButton.Name = "urlButton"
    urlButton.Text = "Open URL in Browser"
    flowPanel.Controls.Add(urlButton)
End Sub


Private Sub urlButton_Click(ByVal sender As Object, ByVal e As EventArgs) Handles urlButton.Click
    Try
        Dim newUri As New Uri(urlTextBox.Text)
    Catch uriEx As UriFormatException
        MessageBox.Show(("Sorry, your URL is malformed. Try again. Error: " + uriEx.Message))
        urlTextBox.ForeColor = Color.Red
        Return
    End Try

    ' Valid URI. Reset any previous error color, and launch the URL in the

    ' NOTE: Depending on the user's settings, this method of starting the

    ' To get around this, start up a specific browser instance instead using one of

    urlTextBox.ForeColor = Color.Black
    Process.Start(urlTextBox.Text)
End Sub

注解

设置 GrowAndShrink 值会生成与启用属性但未启用属性的控件 AutoSize 相同的行为

AutoSizeMode 属性。 遵循 MinimumSize 属性和 MaximumSize 属性，但忽略该属性的 Size 当前值。
