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)

參數

g: Graphics

Graphics他們用來畫選項按鈕。

glyphLocation: Point

然後 Point 畫選項按鈕的字形。

state: RadioButtonState

其中一個 RadioButtonState 值是指定選項按鈕視覺狀態的。

備註

如果作業系統啟用視覺樣式，且視覺風格套用到目前應用程式，此方法會繪製出顯示當前視覺樣式的選項按鈕。否則，此方法會以經典 Windows 風格繪製選項按鈕。

然後 Point 畫選項按鈕的字形。

textBounds: Rectangle

那個 Rectangle 要吸引 radioButtonText 進去的。

radioButtonText: String

然後 String 用選項鍵來繪製。

font: Font

該 Font 應用於 radioButtonText。

focused: Boolean

true繪製焦點矩形;否則，。 false

範例

以下程式碼範例使用自訂 DrawRadioButton(Graphics, Point, Rectangle, String, Font, Boolean, RadioButtonState) 控制項 OnPaint 的方法，在滑鼠指標位置決定的狀態中繪製選項按鈕。此程式碼範例是本類別更大範例 RadioButtonRenderer 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
