 Posted: Fri Aug 26, 2005 3:55 am Post subject: Obrun an Openbox/*Box Run dialog written in Python and GTK2 |
 |
|
Last update: 28-08-2005
Hi,
This is a small "run dialog" program that I wrote, there are probably a dozen like it but it was a good practice for me since I'm a beginner in Python and I thought that someone else might find it useful.
It saves a history list of the commands that you ran, and keeps them in ~/.obrun_history, the number of items it saves can be changed by editing obrun.py and changing self.maxHistoryEntries from 20 to whatever you want.
You'll need Python, Gtk+2.4+ and Pygtk-2.6.1+ (it might work with older versions too).
I'd appreciate any comments/suggestions.
To see a screenshot of it you can clickhttp://cypher.homelinux.net:9000/~ghost/images/obrun.png, and a quick link to obrun.py can be found in here as well http://cypher.homelinux.net:9000/~ghost/files/obrun.py. I'm hosting those 2 files on my main box so it might not always be online, if thats the case then the code listing below is the same so you can just copy and paste it.
If you save this as obrun.py and put it in ~/.config/openbox , then just edit rc.xml and add something like
| Code: |
<keybind key="A-F2">
<action name="Execute"><execute>~/.config/openbox/obrun.py</execute></action>
</keybind>
|
and restart Openbox then you can launch this by pressing ALT+ F2.

Edit: Added a delete-event callback.
Edit2: Fixed a typo when calling connect with the "delete-event"
Edited on 27/08/2005: Added links for a screenshot and a direct link to the file.

I get this error.
Traceback (most recent call last):
File "./obrun.py", line 132, in ?
runDialog = ObRun()
File "./obrun.py", line 93, in __init__
self.connect("delete-event", self.deleteEventCallback())
TypeError: deleteEventCallback() takes at least 3 arguments (1 given) |

I made a last minute typo  I updated the listing now to include it, basically this is what should be changed:
| Code: |
self.connect("delete-event", self.deleteEventCallback())
|
should be:
| Code: |
self.connect("delete-event", self.deleteEventCallback)
|
let me know if this fixes it or not. |

Can you show a screenshot of this program?

ClieX,
Thanks for the input 
I'm planning of adding a keybinding for a quick exit, for example, pressing ESC will quit it.
The links should be up most of the day until I shutdown the box around 3 AM. |

A quick update, I just modified the code to fix a small bug where it was storing duplicate entries for the programs, for example, suppose you run xclock twice, then it will store xclock twice in the history file (so when you run the dialog and press 'x' you will see xclock twice), I fixed this by adding a small duplicateExists() function which takes care of that, you will have to delete the history file (~/.obrun_history) if it contains duplicate entries (I didn't add the check to the loadHistory() function since I didn't think it was neccessary if saveHistory() was fixed).
If you have any problems/comments post back. |
