DrawRadioButton(Graphics, Point, RadioButtonState)

在指定状态下和指定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

用于绘制选项按钮的 Graphics。

glyphLocation: Point

Point，用于绘制选项按钮标志符号的位置。

state: RadioButtonState

RadioButtonState 值之一，它指定选项按钮的可视状态。

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，则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。

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。此代码示例是为类提供的大型示例的 RadioButtonRenderer 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
    {

        if (!clicked)
        {
            clicked = true;

            state = RadioButtonState::CheckedPressed;
            Invalidate();

        {
            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,

}

// Draw the radio button in the checked or unchecked state.
