From 43f3482adf5eee657e5ba922733dfff6600c4e14 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?H=C3=A5kan=20Mattsson?= Date: Wed, 3 Feb 2010 08:59:06 +0000 Subject: OTP-8058 The GUI parts are rewritten to use wxWidgets. Thanks Olle Mattsson! For the time being it is still possible to use the old GS based version of the tool, but it is deprecated. The wxWidgets based version is started by default. A new tutorial has been added to the documentation. It is based on Jayson Vantuyl's article http://souja.net/2009/04/making-sense-of-erlangs-event-tracer.htm l. The functions et:trace_me/4 and et:trace_me/5 has been introduced in order to replace the deprecated functions et:report_event/4 and et:report_event/5. Hopefully the new names makes it a little more obvious what the intended usage of the functions are. A print function has been added to the GUI, in order to enable printing of sequence charts. More functionality for hiding unwanted events has been added to the GUI. The max_events, hide_unknown and display_mode configuration parameters to et_viewer is not used any more. Now the event cache in the Viewer only contains those events that actually are displayed in the GUI. --- lib/et/doc/src/et_intro.xml | 82 +++++++++++++++++++++++++++++---------------- 1 file changed, 53 insertions(+), 29 deletions(-) (limited to 'lib/et/doc/src/et_intro.xml') diff --git a/lib/et/doc/src/et_intro.xml b/lib/et/doc/src/et_intro.xml index 8dfa678b11..0c5fb14d55 100644 --- a/lib/et/doc/src/et_intro.xml +++ b/lib/et/doc/src/et_intro.xml @@ -4,7 +4,7 @@
