Some more Functionalities with the Designer made form dialog
I have made a form with the help of the designer. But I need to add many more functionalities. How do I add them and most importantly where do I add them. Should I add them in *.ui.h or *.ui or main.cpp coz any other file is over written after compiling. The functionalities I want to add are
1. Multitasking with threads...I plan to have a routine in QT which can work all time...i.e. threaded.
2. when user presses start command button... i save a the values in 5 different textboxes in a file
3. Take in a data from another file and show it to the user in LCD.
Please help me as I am not very good at QT but have to do this work as a part of a bigger project.
Any help would be greatly appreciated.
I would recommend taking some time to work through the examples and demos which come with QT. There are a lot of them, and they cover all of the tasks you mentioned.
The QT documentation is second to none in my opinion. I would take a look at the following classes: QThread, QFile, QTextStream, QVariant (if you want to save numbers to a file using a human-readable string, this class will help you with the conversion to C integer or float types).
Also, do try to understand the signal/slot mechanism. This is thread safe, so you can pass data between thread using this mechanism without worrying about all that stuff.
Thanks...I would do the requisite and get back to you in case some help is required.
