How to: Create a Shaped Windows Form
This example gives a form an elliptical shape that resizes with the form.
Example
protected:
virtual void OnPaint(
System::Windows::Forms::PaintEventArgs^ e) override
{
System::Drawing::Drawing2D::GraphicsPath^ shape =
gcnew System::Drawing::Drawing2D::GraphicsPath();
shape->AddEllipse(0, 0, this->Width, this->Height);
this->Region = gcnew System::Drawing::Region(shape);
}
protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)
{
System.Drawing.Drawing2D.GraphicsPath shape = new System.Drawing.Drawing2D.GraphicsPath();
shape.AddEllipse(0, 0, this.Width, this.Height);
this.Region = new System.Drawing.Region(shape);
}
Protected Overrides Sub OnPaint( _
ByVal e As System.Windows.Forms.PaintEventArgs)
Dim shape As New System.Drawing.Drawing2D.GraphicsPath
shape.AddEllipse(0, 0, Me.Width, Me.Height)
Me.Region = New System.Drawing.Region(shape)
End Sub
Compiling the Code
This example requires:
- References to the System.Windows.Forms and System.Drawing namespaces.
This example overrides the OnPaint method to change the shape of the form. To use this code, copy the method declaration as well as the drawing code inside the method.
