Arduino + Qt with QextSerialPort

Last time I showed you a little play-around with Arduino and two servos.

Reminder: arduino-double-servo-sketch

Since my aim is to use it to control a webcam built on top of the two servos I have a program with a GUI that can do some image processing. I want to be able to control my “webcam-head” via the GUI so I need to send messages to the Arduino from my Qt (surprised?:D) application. I chose QextSerialPort because a friend of mine got nice experiences with it. I work with Ubuntu but it is also available on Windows systems.

Pop-out widget into a separate window with Qt

Have you ever felt that your application needs an extra window? When the user has 2 screens available how great would it be to separate the widgets you had to push into a tab widget!

I have good news for you: this can be done simply with Qt.

Let’s say we have a window with two widgets. They are quite important so we’d like the user to see both of them if possible. What can we do about it?
