[Level 2] How to display GUI to remote host.

If you want to display GUI from remote host to local host.
You can enable it as following steps:
1. enable gdm tcp listener.

local# vi /etc/gdm/gdm.schemas
...
 <schema>
<key>security/DisallowTCP <key>
<signature>b<signature>
<default>false<default>
<schema>
...  
PS. default is true.

2. restart local gdm.

local# pkill -HUP X


3. enable remote session.

local# xhost +


4. setting remote display

remote# export DISPLAY=local_ip:0.0
or login remote server with ssh -X
local# ssh -X remote-host

5. try with xclock

remote# xclock


Wish this helps.

If you want to give a list for user to choose, you can use the option "--list". The command synopsis as below: SYNOPSIS      zenity  --list [--title=title] [--window-icon=path] [--width=width]    [--height=height] [--timeout=seconds] [--column=text] [--checklist]       [--radiolist] [--separator=character] [--multiple] [--editable] [--print-column=number] [--hide-column=number] Just like " --calendar ", if you press "ESC" key or click button "Cancel", the return code will be "1".

[Level 2] iif in Python

If you want to implement iif in Python, please refer to the following sample code: #!/bin/env python def iif(b): return 'It\'s True' if b else 'It\'s False' print iif(True) print iif(False) And the following sample, guess what will you get! #!/bin/env python b = True print 'b: %s' % 'Ture' if b else 'False' b = False print 'b: %s' % 'Ture' if b else 'False' Result: $ ./iif.py b: Ture False The second result is "False", not "b: False". Why??? Because the prededence of string concatenation is higher than if. Therefore you need to use () to make it correct. #!/bin/env python b = True print 'b: %s' % 'Ture' if b else 'False' b = False print 'b: %s' % ('Ture' if b else 'False') Wish this helps. regards, Stanley Huang
