I'm working on a GUI project that involves continuously reading data (which is a waveform - like a simple sinusoid) from a file (which gets periodically updated), and displaying it as a pixel-based image. I was able to follow some tutorials online and install Allegro and successfully plot a static 2d image.
However, what I want to really do (to complete the project) is to create a decent GUI window that has some options (like radio-buttons and boxes where user can input some numbers). Something like the attachment figure.
The reason I want these features in my GUI window is that I would be reading the waveform data from a file and performing some math operations (which depend on parameters given as input by user) on the data before finally displaying it on the GUI.
I tried for over a week to find tutorials of Allegro that will allow inclusion of such buttons and boxes, but in vain. I found from a webpage (http://www.opengl.org/resources/features/fontsurvey/ ) that a GUI window like the attached pic can be done using openGL, but no details are given as to how to develop such a GUI.
Now finally, what I want is to know if any of you guys have any tutorial that shows me how to develop a GUI like the one attached, except that instead of the big text "Survey of...", I would be displaying my waveform. Please...please point me to any tutorial or any other source that will let me develop this kind of GUI (using any kind of package graphics).
