You should just make a correction: connect your c7 updateUI signal in your MainWindow's constructor rather than in c7's constructor. It will make c7 completely independent of the GUI on top of it.

Also from a pure reading point of view, you should add the missing emit keyword, it will make your code easier to understand

what I need to run application on platform with just framebuffer, I am little confused here. Is there some sort Qt server like X server or do I need install framework on target machine?

SGaist

What version of Qt are you using ?

joker_hr

it is standard package of fedora 19, version 3.0

SGaist

I meant for your target

joker_hr

I am not using anything yet :)
question
For using with X11 I will install * Qt libraries 4.8.5 for Linux/X11 *
and for using directly to framebuffer i will install Qt libraries 4.8.5 for embedded Linux?
How applications behave with static build on linux targets?

SGaist

Pretty much it's that yes. Depending on what you will run on your target, you might need to compile Qt yourself.

I don't exactly understand your question about static application behavior

joker_hr

I thought about static compiling of executable file that has all necessary libs inside.

SGaist

The application behavior won't change because of the build type. However you should first check that you can use a static build, there are licenses implication with it.
