I need some help from you guys.
I need to display data from 8 different sonar. In my app i'm receiving 4 different data frame types using rs232. One of this types is the sonar data. I receive the sonar data every 80ms. For each sonar the value range 0-255.
For rs232 reception i'm using a workerthread that only emits a signal to guithread when a complete and valid data frame is received.
What i need to display is something like the following image and then depending on the value, fill with green colour representing the clear area in front of the sonar.
What is the best way to do it?
I'm new to Qt..
