改变多边形颜色
本文关键字:颜色 多边形 改变 | 更新日期: 2023-09-27 18:02:36
我从c#代码中添加MouseEnter
事件处理程序,如下所示:
var polygon = new Polygon { StrokeThickness = 1, Fill = Brushes.Blue };
polygon.MouseEnter += new MouseEventHandler(p_MouseLeftButtonDown2);
...
void p_MouseLeftButtonDown2(object sender, MouseEventArgs e)
{
MessageBox.Show("Entered");
}
如何改变p_MouseLeftButtonDown2
中多边形的颜色?
有很多方法可以解决这个任务。我认为你在WPF中真的很新,也许在c#中也是,所以我想以下解决方案适合你:
void p_MouseLeftButtonDown2(object sender, MouseEventArgs e)
{
Polygon poly = sender as Polygon;
if (poly != null)
poly.Fill = Brushes.Red;
}
Storyboard
将其放入p_MouseLeftButtonDown2
方法:
((Polygon)sender).Fill = Brushes.Black; //whatever color you need
如果我是你,我会考虑用MVVM方法替换这整个代码隐藏的可能性。
