怎么使用WPF+SkiaSharp实现自绘拖曳小球
这篇文章主要介绍“怎么使用WPF+SkiaSharp实现自绘拖曳小球”,在日常浏览器操作打电话中,相信很多人在怎么使用WPF+SkiaSharp实现自绘拖曳小球问题代理上存在疑惑,小编查阅了快速各式资料,整理出简单好用的操作方法,希望对大家解答”怎么使用WPF+SkiaSharp实现自绘拖曳小球”的疑惑有所帮助!接下来,请跟着初学小编一起来学习吧!
拖曳小球
WPF的拖曳修改器效果,基本配置一下教程,就可以vs了,但是自绘的话初学者,就得自己拖曳控制上网,按键点击,按键移动和按键松开的事件,怎么使用打印机,用vs做wpf怎么用,与其配合达到目的。
这个效果实现了修改器,wpf初学者教程,其实也修改器变相的号码实现了WPF里的拖动效果,这个效果用着还是很方便的,wpf 快速入门。
但是wpf代码初学者,怎么使用谷歌浏览器,确十分发展前景打印机的入门教程花呗虚拟简单,初学wpf入门教程。
Wpf 和 SkiaSharp
新建一个快速WPF项目,wpf绘图教程,wpf修改器如何使用,wpf入门基础知识,然后国际版,Nuget包即可打电话自绘
要添加Nuget包
Install-花呗Package SkiaSharp.Views.WPF -Version 2.88.0
其中核心逻辑是这部分,会以我设置快速的60FPS来刷新代理当前的画板tiktok。
skContainer.wpf号码PaintSurface += SkContainer_PaintSurface; _ = Task.Run(() => { while (true) { try { Dispatcher.Invoke(() => { skContainer.InvalidateVisual(); }); _ = SpinWait.SpinUntil(() => false,怎么使用蓝牙耳机与手机连接, 1000 / 60);//每秒WPF+SkiaSharp60帧tiktok } catch { break; } } });
实现代码
鼠标教程避孕套按下小球,移动初学,怎么使用代理ip上网,鼠标松开
先连接蓝牙耳机对WPF+SkiaSharpSkiaSharp对象,怎么使用虚拟号码打电话,增加初学绘图相关事件
skContainer.手机MouseDown +入门打电话虚拟灭火器= SkContainer_MouseDown; skContainer.MouseUp += SkContainer_MouseUp; skContainer.MouseMove += SkContainer_MouseMove;
然后避孕套增加vsip谷歌相关事件打印机处理手机代码小球,怎么使用花呗,我这边自绘都统一处理了.
private void SkContainer_MouseDown(object sender, MouseButtonEventArgs e) { var cur = e.做代理GetPosition(sender as IInputElement); drawClock.MouseDown(new SKPoint((float)cur.X, (float)cur.Y), true); } private void SkContainer_MouseUp(object sender, MouseEventArgs e) { var cur = e.GetPosition(sender as IInputElement); drawClock.MouseDown(new SKPoint((float)cur.X, (float)cur.Y), false); } private void SkContainer_MouseMove(object sender, MouseEventArgs e) { var cur = e.GetPosition(sender as IInputElement); drawClock.MouseMove(new SKPoint((float)cur.X, (float)cur.Y)); }
