Introduction

DrawTools sample shows how to create a Windows Forms application for drawing graphic objects in a Windows client area using mouse and drawing tools. Drawing tools implemented in this sample are: Rectangle, Ellipse, Line, and Pencil. There are well-known techniques for creating such type of applications, like: interaction with mouse, flicker-free drawing, implementing of drawing and selection tools, objects selection, managing of objects Z-order etc. MFC developers may learn all this stuff from MFC sample DRAWCLI. DrawTools C# program reproduces some of DRAWCLI functionality and uses some design decisions from this sample.

DrawTools solution contains two projects: DrawTools Windows Forms application and DocToolkit Class Library. DrawTools implements specific application stuff, and DocToolkit contains some standard classes for file managing.

Tips

1. copy the DrawTools project from codeproject.com( ORIGINAL PROJECT : http://www.codeproject.com/KB/graphics/drawtools.aspx )

2. rewrite the CommandDelete.cs file to fix the order of Undo / Redo

3. add new DrawObject ( Triangle )

Target

1. rewrite CommandDelete.cs -- finished

2. add new DrawObject ( Triangle, just for fun ) -- finished

3. ...
