Source:: CheckBoxRenderer.cs

Draws a check box control in the specified state and location.

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

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

static member DrawCheckBox : System.Drawing.Graphics * System.Drawing.Point * System.Windows.Forms.VisualStyles.CheckBoxState -> unit

Public Shared Sub DrawCheckBox (g As Graphics, glyphLocation As Point, state As CheckBoxState)

Parameters

g: Graphics

The Graphics used to draw the check box.

glyphLocation: Point

The Point to draw the check box glyph at.

state: CheckBoxState

One of the CheckBoxState values that specifies the visual state of the check box.

Remarks

If visual styles are enabled in the operating system and visual styles are applied to the current application, this method will draw the check box with the current visual style. Otherwise, it will draw the check box with the classic Windows style.

Examples

The following code example uses the DrawCheckBox(Graphics, Point, Rectangle, String, Font, TextFormatFlags, Boolean, CheckBoxState) method in a custom control's OnPaint method to draw a check box in the state determined by the location of the mouse pointer. This code example is part of a larger example provided for the CheckBoxRenderer class.

// Draw the check box in the current state.
virtual void OnPaint(PaintEventArgs ^e) override
{
    Control::OnPaint(e);

    CheckBoxRenderer::DrawCheckBox(e->Graphics,
        ClientRectangle.Location, this->getTextRectangle(), this->Text,
        this->Font, TextFormatFlags::HorizontalCenter,
        clicked, state);
}


// Draw the check box in the checked or unchecked state, alternately.
virtual void OnMouseDown(MouseEventArgs ^e) override
{
    Control::OnMouseDown(e);

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

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

    CheckBoxRenderer.DrawCheckBox(e.Graphics,
        ClientRectangle.Location, TextRectangle, this.Text,
        this.Font, TextFormatFlags.HorizontalCenter,
        clicked, state);
}

// Draw the check box in the checked or unchecked state, alternately.
protected override void OnMouseDown(MouseEventArgs e)
{
    base.OnMouseDown(e);

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

' Draw the check box in the current state.
Protected Overrides Sub OnPaint(ByVal e As PaintEventArgs)
    MyBase.OnPaint(e)
    CheckBoxRenderer.DrawCheckBox(e.Graphics, _
        Me.ClientRectangle.Location, TextRectangle, Me.Text, _
        Me.Font, TextFormatFlags.HorizontalCenter, _
        clicked, state)
End Sub

' Draw the check box in the checked or unchecked state, alternately.
Protected Overrides Sub OnMouseDown(ByVal e As MouseEventArgs)
    MyBase.OnMouseDown(e)
    If Not clicked Then
        With Me
            .clicked = True
            .Text = "Clicked!"
            .state = CheckBoxState.CheckedPressed
        End With
        Invalidate()
    Else
        With Me
            .clicked = False
            .Text = "Click here"
            .state = CheckBoxState.UncheckedNormal
