<kfunk> : small note: use KColorScheme in ArduinoWindow::getRedRichTextSelected, instead of a hard-coded 'red'
e.g. KColorScheme(KColorScheme::View, KColorScheme::NegativeText)
or sth else as 2nd param -- I don't think it's supposed to be 'negative'

always use braces please ... also auto enable = state == Qt::Checked would be simpler imo ;)

don't worry, you can occasionally include something :D

I don't really like this lastIndexOf(0), where is it written that the frequency ends with a 0? it could reasonably be 3999999 or something like that.

this file is a configuration output from firsttimewizard.h.in, must be removed

can I use Qt::color, e.g: Qt::red ?

Ok, I get now.
I will use palette.

did not quite understand

I will try to talk with someone to help me with Solid or use QSerial for while.

don't use new or a pointer, just have a "QProcess m_process" member
