From 453f80e38bcb0945e7eac27a5917dce9bdc6446b Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Sat, 30 Nov 2019 06:38:01 +0100 Subject: Bug 1156: LinuxKeyEventTracker, LinuxMouseTracker: Adding property to disable each LinuxKeyEventTracker also disable the eventX reading by default, but can be enabled via new property. The 'return bug' (crash due to underlying console) is indeed not occuring when using a VT w/o running console application underneath. As Xerxes showed, one may use chvt to a free known VT or openvt. --- .../newt/driver/linux/LinuxKeyEventTracker.java | 33 ++++++++++++++++------ .../newt/driver/linux/LinuxMouseTracker.java | 23 +++++++++++---- 2 files changed, 42 insertions(+), 14 deletions(-) (limited to 'src/newt/classes') diff --git a/src/newt/classes/jogamp/newt/driver/linux/LinuxKeyEventTracker.java b/src/newt/classes/jogamp/newt/driver/linux/LinuxKeyEventTracker.java index 402ad0051..b6503c1ed 100644 --- a/src/newt/classes/jogamp/newt/driver/linux/LinuxKeyEventTracker.java +++ b/src/newt/classes/jogamp/newt/driver/linux/LinuxKeyEventTracker.java @@ -47,6 +47,7 @@ import jogamp.newt.driver.KeyTracker; import com.jogamp.common.nio.StructAccessor; import com.jogamp.common.os.Platform; import com.jogamp.common.util.InterruptSource; +import com.jogamp.common.util.PropertyAccess; import com.jogamp.newt.Window; import com.jogamp.newt.event.InputEvent; import com.jogamp.newt.event.WindowEvent; @@ -55,13 +56,13 @@ import com.jogamp.newt.event.WindowUpdateEvent; import com.jogamp.newt.event.KeyEvent; /** - * Experimental native key event tracker thread for GNU/Linux. + * Native key event tracker thread for GNU/Linux. *
