how do can I use my C++ code in qt and can it be translated into QT code

[ChrisW67]

Qt is a library not a language. Qt is written in C++ and designed to be used from C++ programs (although there are bindings for Python). All you require is a knowledge of C++ to learn how to use the Qt library. There are plenty of tutorials, examples and demos in the Qt documentation. That documentation is installed with the Qt library: run "assistant" or look at the Help in Qt Creator (if you have that).

Your program is not designed for a GUI, whether it is Qt or any other kind, so you will need to think about how your GUI program should work.

(I also suspect your program does not do what you expect)

My program works perfectly

what I want it to do as far as it working with the GUI is I want the DNA sequence typed in a text field and then press a button and the RNA complement to print out in a second text field.

How should my program be set up?

With two QLineEdits (or a QLineEdit and a QLabel) and a QPushButton. You will need to put them into a parent QWidget with a layout. The QPushButton::clicked() signal can be used to trigger a slot that does your DNA->RNA translation on the text of the input widget and places the result into the result widget. You can use a QValidator to ensure only the character TAGC are accepted and upper case is forced. You use QString instead of your fixed C-style char arrays.

Take a look at the Line Edits Example and the Address Book tutorial.


Your current code assumes that DNA and RNA have been zeroed. This is not a safe assumption: the array contents are undefined. Here is what the array contents were immediately after declaring the arrays:

DNA d8 20 60 00 00 00 00 00 24 23 60 00 00 00 00 00 a0 0e 40 00 00 00 00 00 44 a6 4b 06 c8 7f 00 00 00 00 00 00 00 00 00 00 f0 f7 20 51 ff 7f 00 00 c0 1d 
RNA 00 a3 01 07 c8 7f 00 00 00 00 00 00 00 00 00 00 f0 f7 20 51 ff 7f 00 00 c0 1d 60 00 00 00 00 00 01 00 00 00 00 00 00 00 c5 b0 04 07 c8 7f 00 00 a0 0e

DNA d8 20 60 00 00 00 00 00 24 23 60 00 00 00 00 00 a0 0e 40 00 00 00 00 00 44 a6 4b 06 c8 7f 00 00 00 00 00 00 00 00 00 00 f0 f7 20 51 ff 7f 00 00 c0 1d 
RNA 00 a3 01 07 c8 7f 00 00 00 00 00 00 00 00 00 00 f0 f7 20 51 ff 7f 00 00 c0 1d 60 00 00 00 00 00 01 00 00 00 00 00 00 00 c5 b0 04 07 c8 7f 00 00 a0 0e

Reading in from the file will put a zero terminator after the input data. However, since you do not limit yourself to the valid characters in the input string, or zero-terminate the RNA string after you build it you sometimes get rubbish characters in the output. Never mind, using either std::string or QString will make this problem go away.

Thanks Chris & Stereo
I'm going through the learn QT documentation and I'm really like WOW you can do alot with QT, more than I expected. the QT quick is awesome to it looks like you can design with QML and program with QT C++

Thanks for the help you guys are really inspiring me right now!!!!

Chris it looks like you turned the transcription portion of my code into the translation portion howd you do that???

By having an MSc is astronomy, not genetics, I free myself from the need to understand that transcription and translation have specific meaning in genetics. I meant translation in the computing sense of T translates (or maps) to A, G to C etc. I was not proposing determine the entire gene expression and protein folding result for a given DNA sequence
