The official version of Shed is a hexadecimal editor specially built for Unix/Linux systems. Shed is simple hex The latest version of the editor has a simple and friendly operation interface, and supports functions such as displaying ASCII codes, hexadecimal, octal, decimal and binary. Through Shed software users can edit, search, replace and other operations on these bases to meet a variety of processing needs.

Shed software introduction

​ ​ ​ One of the most useful tools for a programmer is a good hex editor. So, I decided to throw one in together. There are a lot of places where it could use more functionality, such as the find function, but it's still a good hex editor. This is a great example of how to implement a custom document view.

Shed software features

The application is SDI and the views are based on the scroll view class. The data is loaded into CString objects.

I have used CString because of its ease of memory management (getbuffer() and null() are all I need).

The text data of the landscape class is manually drawn twice. The left side is ASCII and the left side is hexadecimal.

Simple highlighting and cursor control are written into the view class, while data operations are handled by the data interface.

Shed software description

           Scrolling may or may not be implemented as expected. I couldn't find good documentation on how to get it to work perfectly, so I set the origin to the top left corner and simply calculated the visible lines myself.

There may be a better way (if there is, tell me), but the end result is that I only draw what I need to make the rendering fast enough to be used. I also managed to avoid everything on the screen except scrolling.
