Remove cursor and evdevtouch input on QT5
-
Hi,
I'm working on a embedded card using Linux, with a touchscreen and Qt5.0.2.
When I launch my application, it looks like this:./myapp -plugin EvdevTouch:/dev/input/event2
evdevtouch: Using device /dev/input/event1
min X: 0 max X: 0
min Y: 0 max Y: 0
min pressure: 0 max pressure: 0
device name: max11801_ts
evdevtouch: Using device /dev/input/event2
min X: 0 max X: 0
min Y: 0 max Y: 0
min pressure: 0 max pressure: 1
device name: eGalax Touch Screen
Protocol type A
Protocol type AFirst, I want to remove the cursor shown along the application, because it's not necessary with a touchscreen. I found this post: http://qt-project.org/forums/viewthread/7698 , but it only works for Qt4 and I don't know how to hide the cursor in Qt5. Plus, I don't use a windowing system (eglfs).
The second problem is, when the application is launched, evdevtouch use only the /dev/input/event1 device by default and I must specify the right one (event2). It works but i want to tell to evdevtouch to not use the event1 device. How to do that ?
Thanks for your help.

Anyone knows the answer to this question? I am also using eglfs, and cannot find how to hide mouse cursor!

And of course, as soon as I posted the question, I found the solution.
Use QT_QPA_EGLFS_HIDECURSOR enviroment variable, and set it to 1. For example, put it in /etc/profile like this:
export QT_QPA_EGLFS_HIDECURSOR=1
