This means anyone disposing it will break it's app under Mono, but will execute correctly under MS runtime. + +------- Additional Comments From [EMAIL PROTECTED] 2006-05-17 22:07 ------- +Oh, that's a good catch. Yesterday I was trying to find out why MS.NET +shows "simple" coordinates on the console output from my simple repro +above (it is rather for fixing bug #78287). + +The example below shows that PaintEventArgs has different +e.ClipRectangle than e.Graphics.ClipBounds on Mono (it might be +different on .NET too but I couldn't find a case). It might be related +to the fact (well, I haven't verified yet) that it creates new +Graphics instance every time. + +-------- +using System; +using System.Drawing; +using System.Windows.Forms; + +public class Test : Form +{ + public static void Main (string [] args) + { + Bitmap bmp = new Bitmap (100, 100); + Graphics g = Graphics.FromImage (bmp); + Console.WriteLine (g.ClipBounds); + + Application.Run (new Test ()); + } + + public Test () + { + Button b = new Button (); + Controls.Add (b); + b.Paint += delegate (object o, PaintEventArgs e) { + Graphics g = CreateGraphics (); + Console.WriteLine (g.ClipBounds); + g = b.CreateGraphics (); + Console.WriteLine (g.ClipBounds); + g = e.Graphics; + Console.WriteLine (g.ClipBounds); + Console.WriteLine (e.ClipRectangle); + }; + } +} + _______________________________________________ mono-bugs maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-bugs
