在指定状态和位置绘制选项按钮控件（也称为单选按钮）。

public:
 static void DrawRadioButton(System::Drawing::Graphics ^ g, System::Drawing::Point glyphLocation, System::Windows::Forms::VisualStyles::RadioButtonState state);

public static void DrawRadioButton(System.Drawing.Graphics g, System.Drawing.Point glyphLocation, System.Windows.Forms.VisualStyles.RadioButtonState state);

static member DrawRadioButton : System.Drawing.Graphics * System.Drawing.Point * System.Windows.Forms.VisualStyles.RadioButtonState -> unit

Public Shared Sub DrawRadioButton (g As Graphics, glyphLocation As Point, state As RadioButtonState)

参数

g: Graphics

Graphics用于绘制选项按钮。

glyphLocation: Point

要 Point 绘制选项按钮标志符号。

state: RadioButtonState

RadioButtonState指定选项按钮视觉状态的值之一。

注解

如果在操作系统中启用了视觉样式，并且视觉样式应用于当前应用程序，此方法将使用当前视觉样式绘制选项按钮。否则，此方法将使用经典Windows样式绘制选项按钮。

示例

下面的代码示例使用 DrawRadioButton(Graphics, Point, Rectangle, String, Font, Boolean, RadioButtonState) 自定义控件 OnPaint 方法中的方法在鼠标指针的位置确定的状态中绘制选项按钮。该代码示例是 RadioButtonRenderer 类中的一个较大示例的一部分。

    // Draw the radio button in the current state.
protected:
    virtual void OnPaint(PaintEventArgs^ e) override
    {
        __super::OnPaint(e);

        RadioButtonRenderer::DrawRadioButton(e->Graphics,
            ClientRectangle.Location, TextRectangle, this->Text,
            this->Font, clicked, state);
    }

    // Draw the radio button in the checked or unchecked state.
protected:
    virtual void OnMouseDown(MouseEventArgs^ e) override
    {
        __super::OnMouseDown(e);

        if (!clicked)
        {
            clicked = true;
            this->Text = "Clicked!";
            state = RadioButtonState::CheckedPressed;
            Invalidate();
        }
        else
        {
            clicked = false;
            this->Text = "Click here";
            state = RadioButtonState::UncheckedNormal;
            Invalidate();
        }
    }

// Draw the radio button in the current state.
protected override void OnPaint(PaintEventArgs e)
{
    base.OnPaint(e);

    RadioButtonRenderer.DrawRadioButton(e.Graphics,
        ClientRectangle.Location, TextRectangle, this.Text,
        this.Font, clicked, state);
}

// Draw the radio button in the checked or unchecked state.
protected override void OnMouseDown(MouseEventArgs e)
{
    base.OnMouseDown(e);

    if (!clicked)
    {
        clicked = true;
        this.Text = "Clicked!";
        state = RadioButtonState.CheckedPressed;
        Invalidate();
    }
    else
    {
        clicked = false;
        this.Text = "Click here";
        state = RadioButtonState.UncheckedNormal;
        Invalidate();
    }
}

' Draw the radio button in the current state.
Protected Overrides Sub OnPaint(ByVal e As PaintEventArgs)
    MyBase.OnPaint(e)
    RadioButtonRenderer.DrawRadioButton(e.Graphics, _
        Me.ClientRectangle.Location, TextRectangle, Me.Text, _
        Me.Font, clicked, state)
End Sub

' Draw the radio button in the checked or unchecked state.
Protected Overrides Sub OnMouseDown(ByVal e As MouseEventArgs)
    MyBase.OnMouseDown(e)

    If Not clicked Then
        clicked = True
        Me.Text = "Clicked!"
        state = RadioButtonState.CheckedPressed
        Invalidate()
    Else
        clicked = False
        Me.Text = "Click here"
        state = RadioButtonState.UncheckedNormal
        Invalidate()
    End If
