示例1: TestHeaderAlignmentOfExpander
public void TestHeaderAlignmentOfExpander()
{
Expander exp = DefaultExpanderToTest;
exp.Width = 400;
exp.Height = 300;
exp.HorizontalContentAlignment = HorizontalAlignment.Center;
exp.Padding = new Thickness(0.0);
Ellipse elps = new Ellipse();
Point pt = new Point();
TestAsync(
exp,
() => elps = (Ellipse)TestExtensions.GetChildrenByType(exp, typeof(Ellipse)),
() => pt = elps.TransformToVisual(exp).Transform(new Point(0, 0)),
() => Assert.IsTrue(pt.X < 5), //// Make sure the ellipse of header/toggle button is at the top left corner of expander.
() => Assert.IsTrue(pt.Y < 5)); //// The pixel difference is less than 5.
}示例2: TestAlignmentOfToggleButtonToExpanderHeader
public void TestAlignmentOfToggleButtonToExpanderHeader()
{
Expander exp = DefaultExpanderToTest;
exp.Width = 200;
exp.Header = "Header of Expander";
exp.ExpandDirection = ExpandDirection.Left;
exp.Padding = new Thickness(0.0);
ToggleButton tgbn = new ToggleButton();
Ellipse elps = new Ellipse();
Point pt = new Point();
TestAsync(

() => elps = (Ellipse)TestExtensions.GetChildrenByType(exp, typeof(Ellipse)),
() => pt = elps.TransformToVisual(tgbn).Transform(new Point(0, 0)),
() => Assert.IsTrue(TestExtensions.AreClose(tgbn.ActualWidth / 2, pt.X - elps.ActualWidth / 2)));
}示例3: IsPointInsideEllipseShape
private bool IsPointInsideEllipseShape(Ellipse ellipseToUse, Point point)
{
EllipseGeometry ellipse = new EllipseGeometry();
ellipse.RadiusX = ellipseToUse.RenderSize.Width / 2;
