Glo How to register button press on Glo?

[j4GGy]

Hi Guys,

I just looked around the forum and I didn't find very much regarding that matter. If there is a thread about it, just point me in the right direction and I'll stand corrected

Anyways... How can I register button presses using QT 4.8 on my Glo? I don't mean the touchscreen, I mean the light and on/off-buttons. So far my application has a main window/widget derived from the QLabel-class. QLabel::keyPressEvent(...) however is not triggered when I press the light or the on/off-button. So my guess is that either I need something like a global hook or more likely I just don't have the right "keyboard"-driver loaded. Adding

export QWS_KEYBOARD=imx508kbd:/dev/input/event0

to the sh-script starting my application did not work, though.

Any suggestions?

cat /dev/input/event0

responds to "Home" and "Power" buttons on my Kobo Touch

I think that I'll implement my own Qt keyboard plugin for my Qt 4.8.4 build soon...

thanks for the response - I knew that /dev/input/event0 corresponds to those button events, but I've never written a keyboard Qt-plugin/driver before...

I am planning on taking a look at the sources of the Kobo-mousedriver when I find the time. Today I just roamed the forum trying to find those - after 1 hour I found out that it was thread #1

It would be nice to have the Kobo QT Keyboard working, but that didn't work for me (using the command in the Main post)

I found the time (and documentation) to build a Qt keyboard driver. Basicly I just transformed sergeyvl12's code for the touchscreen driver to fit the buttons events. It's attached to this post. Using it via

export QWS_KEYBOARD=KoboKBD

or to enable debugging

export QWS_KEYBOARD=KoboKBD:debug

causes Qt to recognize button presses. I only tested it with my Glo which of course only uses the keys 90 (light button) and 116 (on/off-slider). The driver is written in such a way that it will send (almost) everything going on in /dev/input/event0 to Qt's key-processing-system so that one can easily use

QWidget::keyPressEvent(QKeyEvent*)

and

QWidget::keyReleaseEvent(QKeyEvent*)

in applications. That means that it could work on a Touch/Mini/Wifi, too. Would be nice if someone could confirm/disprove that.

I would further really appreciate it if one of the more experienced Qt coders around here would take a look at the source code because for example I have no idea what the unicode parameter is for in the QWSKeyboardHandler's function processKeyEvent. My guess is that it's not important but thats just a guess

edit: woops, there was no debugging implemented in the former attachment... now it's in there and I just found out that there is a third keycode for the kobo glo: 59 - it's when you use a sleepcover!

PS: The driver's written and built with Qt 4.8.4!

Thanks!

It seems that one also has to place the libKoboKBD.so in

QT_PLUGIN_PATH/kbddrivers/
