Wifi Passkey Input w/o keyboard

[quantum.hero]

Just wondering, is it possible to have an on screen keyboard in dialog for passkey entry when setting up wifi? Or another alternative. The rest of the system, once it's configured can be controlled by using only the game controller and doesn't need a keyboard or SSH.
The workaround I currently have is using wicd and a, now unsupported, program in KODI utilizing the on screen keyboard.

Well that would be nice.... Because some computer emulators need a keyboard to work. Even is it "Press 1 for 1 Player game"
So a virtual keyboard just to enter a small text would be nice.

About the Wifi.
I think the easiest and fastetst way is to edit the configs via SSH ot whatever

edit /etc/network/interfaces

set right values here or open cfg-file that is pointed there :)

auto lo
iface lo inet loopback
iface eth0 inet dhcp
auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-ap-scan 1
wpa-scan-ssid 1
wpa-ssid "DEIN-WLAN-NAME"
wpa-psk "DEIN-WLAN-SCHLÜSSEL"

It's for the end-user.
I agree that is easy but it isn't optimal for someone else that just wants to have it run, not needing a keyboard just to input the wifi code at a new location.
Not familiar with dialog though so not sure if it's something that can be done.

Ah okay :)
For the end user is imho the best solution the implementation of WPS into RetroPie. But afaik WPS does not work with the build in RPi3 chipset so it would be a feature for the RPi 0+1+2 only :(

Well then better a virtual keyboard :)
