Examples

The following code example uses the GetGlyphSize method to determine the bounds of the option button text. This code example is part of a larger example provided for the RadioButtonRenderer class.

    // Define the text bounds so that the text rectangle
    // does not include the radio button.
public:
    property Rectangle TextRectangle
    {
        Rectangle get()
        {
            Graphics^ g = this->CreateGraphics();

            textRectangleValue.X = ClientRectangle.X +
                RadioButtonRenderer::GetGlyphSize(g,
                RadioButtonState::UncheckedNormal).Width;
            textRectangleValue.Y = ClientRectangle.Y;
            textRectangleValue.Width = ClientRectangle.Width -
                RadioButtonRenderer::GetGlyphSize(g,
                RadioButtonState::UncheckedNormal).Width;
            textRectangleValue.Height = ClientRectangle.Height;
         
            delete g;                

            return textRectangleValue;
        }
    }

// Define the text bounds so that the text rectangle 
// does not include the radio button.
public Rectangle TextRectangle
{
    get
    {
        using (Graphics g = this.CreateGraphics())
        {
            textRectangleValue.X = ClientRectangle.X +
                RadioButtonRenderer.GetGlyphSize(g,
                RadioButtonState.UncheckedNormal).Width;
            textRectangleValue.Y = ClientRectangle.Y;
            textRectangleValue.Width = ClientRectangle.Width -
                RadioButtonRenderer.GetGlyphSize(g,
                RadioButtonState.UncheckedNormal).Width;
            textRectangleValue.Height = ClientRectangle.Height;
        }

        return textRectangleValue;
    }
}

' Define the text bounds so that the text rectangle 
' does not include the radio button.
Public ReadOnly Property TextRectangle() As Rectangle
    Get
        Using g As Graphics = Me.CreateGraphics()
            With textRectangleValue
                .X = Me.ClientRectangle.X + _
                    RadioButtonRenderer.GetGlyphSize(g, _
                    RadioButtonState.UncheckedNormal).Width
                .Y = Me.ClientRectangle.Y
                .Width = Me.ClientRectangle.Width - _
                    RadioButtonRenderer.GetGlyphSize(g, _
                    RadioButtonState.UncheckedNormal).Width
                .Height = Me.ClientRectangle.Height
            End With
        End Using
        Return textRectangleValue
    End Get
End Property
