The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Where to retrieve in main (c++) what is entered into a qt gui form

Asked by lwdalton3 in C++ Programming Language, Linux, QT Programming Language

Tags: retrieve, available, memory, program, qt

With QT3 available with Fedora I have a simple aspiration. I would like to enter into a lineedit widget a file name (a cstring) and have my C++ program go from there and do lots of neat stuff with processing the file. The latter has been pretty much accomplished. Back to Qt3-- I have figured out how to build a form with a textlabel, a lineedit, and a pushbutton. Three simple things easily accomplished in RealBasic, but amazingly less than obvious for QT. Still I would like to give Qt a shot, given open platform, and GNU etc etc

However I cannot figure out where what is entered into the lineedit box ends up. The form is called from main, but I cannot see that anything is returnd to main, and if so where is it? Is it hidden somewhere in a pointer to memory that was allocated by new? If so where is the pointer? I can't see that any pointer is initialized in main that would then have a cstring placed therein. Maybe the memory is allocated in some far off function but I don't see that a pointer is returned. Where is what is entered into the form available in main? Maybe Qt is limited to only the pro's, but any help is appreciated.

And, if so my alternative question is how could I call my C++ program from RealBasic. RealBasic does a fairly decent job in my opinion of making their GUI interface understandable, but I can't find in their documentation the procedure for passing parameters to a C++ plug in. Any help on this will be appreciated as well (only if my Qt question is beyond easy answer). Again I am somewhat trying to avoid realBasic because it appears to be too proprietary (and Visual C)

Thanks in advance LD
