[Rock-dev] gui/vizkit (master) will be updated on Monday

[Alexander Duda]

Vizkit master was updated. If you have any trouble please report it to 
the mailing list.

The documentation should be updated by tomorrow:
http://rock-robotics.org/master/documentation/graphical_user_interface/200_simple_gui.html

Greets Alex

Example from the Doc:

# loading library
require 'vizkit'

# initialize Orocos layer
Orocos.initialize

# load GUI created with the Qt Designer
widget = Vizkit.load "simple_gui.ui"
widget.show

# connect the widget with the task "simple_task"
widget.connect_to_task "simple_task" do |task|

     # connect the output port text_message with the text box slot setText
     text_box.connect PORT(:text_message), SLOT("setText(QString)")

     # generate a new sample each time the button is clicked
     # and show a message box if there is a connection error
     g = lambda{"it is #{Time.new.to_s}"}
     c = lambda{|msg| Qt::MessageBox.warning(widget,"ComErr",msg) if msg 
!= "OK"}
     button.connect SIGNAL(:clicked), PORT(:input),:getter => 
g,:callback => c

     # disable the GUI until the task is reachable
     task.on_reachable {widget.setEnabled(true)}
     task.on_unreachable {widget.setEnabled(false)}
end

#run qt main loop
Vizkit.exec
