My First GUI program

Long time no post!, I know

Since Last time I studied Ubuntu I didn’t post, because I keep being busy all the time, and I think I wont be back to post about Ubuntu soon.

No let’s move to explain the subject !!

Yea I made my first GUI program, This was a great Algorithms program to work on, even that it was an algorithms project but the User Interface was a must.

The project looking through an algorithmically perspective was, a Binary Search Tree which has a special feature which is :

The Binary Search Tree has two keys, not as the ordinary one which has only one.

To represent this feature we used two methods :

1. To create two trees, first one for “key1 (s) category” and the second one for “key2(s) category”.
2. To create one tree, but arrange the nodes in odd levels compared to key2, and arrange the nodes in even levels compared to key1.

The programming aspect of the project was :

Procedural programming using Pascal and the interface was done using Delphi7.

1. Insert nodes to both trees.
2. Search for specific nodes in both trees.
3. Delete nodes from both trees.
4. Draw both trees.
5. Draw nodes in specific range.

Last line notes :

• I posted this project and its source code, because I’m open with my own project “viva open source”
• If you noticed I mentioned “we”, because as usual me and my bests did this project, but I had the chance to work more on this project than Alaa` and Zeana, so there were some “I”s .

Please don’t hesitate to post your remarks, I appreciate criticism more the praising, and I hope this can be useful.

Have fun!
