DrawString with character wrapping
I'm creating a fatal error dialog for a Windows Mobile Application using C#. The problem is when I try to draw the stacktrace using DrawString
, half of my stacktrace is getting clipped off because DrawString
uses word wrapping instead of character wrapping.
For those who don't understand the explanation:
When i draw the stacktrace, it comes out as this:
at
company.application.name.space.Funct
at
company.application.name.Function(St
at
etc. etc.
And i want it to print like this:
at
company.application.name.space.Funct
ion(String sometext, Int32 somenumbe
r)
at
company.application.name.Function(St
ring sometext, Int32 somenumber, Int
32 anothernumber)
at
etc. etc.
Is this possible in Csharp?
Reproducing the issue:
Create a new smart device project. (Device application)
Replace the Form1 code with the following:
public partial class Form1 : Form { RectangleF _rect = new RectangleF(); String _stackTrace = @"at System.Net.Sockets.Socket.ReceiveNoCheck(Byte[] buffer, Int32 index, Int32 request, SocketFlags socketFlags) at System.Net.Sockets.Socket.ReceiveAsyncRequest.doRequest() at System.Net.Sockets.Socket.AsyncRequest.handleRequest() at System.Net.Sockets.Socket.WorkerThread.doWork() at System.Net.Sockets.Socket.WorkerThread.doWorkI(Object o) at System.Threading.ThreadPool.WorkItem.doWork(Object o) at System.Threading.Timer.ring()"; protected override void ScaleControl(SizeF factor, BoundsSpecified specified) { _rect.X = 24 * factor.Width; _rect.Y = 10 * factor.Height; _rect.Width = 192 * factor.Width; _rect.Height = 274 * factor.Height; } public Form1() { InitializeComponent(); } protected开发者_如何学C override void OnPaint(PaintEventArgs e) { base.OnPaint(e); using (Pen borderPen = new Pen(this.ForeColor, 1)) { Rectangle borderRect = Rectangle.Round(_rect); borderRect.Inflate(1, 1); e.Graphics.DrawRectangle(borderPen, borderRect); } using (StringFormat stringFormat = new StringFormat()) using (SolidBrush stringBrush = new SolidBrush(this.ForeColor)) { e.Graphics.DrawString(_stackTrace, this.Font, stringBrush, _rect, stringFormat); } }
}
Run the project.
If you use the overload of DrawString that takes a RectangleF, it should use character-wrapping. How are you calling DrawString()?
