C#处理Paint事件的方法
本文实例讲述了C#处理Paint事件的方法。分享给大家供大家参考。具体方法如下:
usingSystem; usingSystem.Collections.Generic; usingSystem.ComponentModel; usingSystem.Data; usingSystem.Drawing; usingSystem.Text; usingSystem.Windows.Forms; namespaceWindowsApplication2 { publicpartialclassForm5:Form { booldrawElipse=false; publicForm5() { InitializeComponent(); this.SetStyle(ControlStyles.ResizeRedraw,true); } privatevoidForm5_Load(objectsender,EventArgse) { } privatevoidbutton1_Click(objectsender,EventArgse) { this.drawElipse=!this.drawElipse; this.Invalidate(true); } privatevoidForm5_Paint(objectsender,PaintEventArgse) { if(!this.drawElipse)return; Graphicsg=e.Graphics; g.FillEllipse(Brushes.DarkBlue,this.ClientRectangle); } } }
希望本文所述对大家的C#程序设计有所帮助。
