我在WPF中绘制了SQUARE和其他形状。这样,在wpf中删除矩形/元素
private Rect DrawSquare(Rect bounds, InkCanvas canvas)
{
Rectangle recta = new Rectangle();
recta.Stroke = Brushes.Black;
//recta.Fill = Brushes.Blue;
recta.StrokeThickness = 4;
recta.Width = bounds.Width;
recta.Height = bounds.Height;
InkCanvas.SetLeft(recta, bounds.Left);
InkCanvas.SetRight(recta, bounds.Right);
InkCanvas.SetTop(recta, bounds.Top);
canvas.Children.Add(recta);
return bounds;
}
,我可以删除随机线与
private void myInkCanvas_SelectionChanging(object sender, InkCanvasSelectionChangingEventArgs e)
{
else if (toolbarMode == ToolbarMode.Delete)
{
myInkCanvas.Strokes.Erase(e.GetSelectedStrokes().GetBounds()); //can delete random lines
ReadOnlyCollection<UIElement> elements = e.GetSelectedElements();
foreach (UIElement element in elements)
{
/*String ShapeName = ((System.Windows.Media.Visual)(element)).ToString();
if (ShapeName.Contains("Rectangle"))
{
Rectangle recta = (Rectangle)element;
recta.Fill = Brushes.Blue;
}*/
myInkCanvas.Children.Remove(element); //cant delete shapes!!?
}
}
}
我可以删除随机线,但我不能删除形状
我哪有?
我想删除所选 随机线(myInkCanvas.Strokes.Erase(E .GetSelectedStrokes()。GetBounds());) 和定义的形状(椭圆,矩形) myInkCanvas.Children.Remove .. ?? – tayfun 2012-08-07 08:25:10
我真的不明白你想要做什么,为什么它不工作。您可以使用删除从画布中删除形状。 – 2012-08-07 10:40:41
