Programming :: Automatically Scrolling Text Box In PyGTK?

Jan 4, 2010

I am playing around with PyGTK and come across a problem: When I put a TextView inside a ScrolledWindow, and type text into the TextView until it reaches the edge, the cursor goes outside the viewport and I can't see what I'm typing. How to make it so that the ScrolledWindow automatically scrolls so that the caret in the TextView is always in visible?

Programming :: Create PyGTK Gnome Screensaver?

Dec 15, 2010

I have created a PyGTK app (a binary clock) that I would like to turn into a screensaver. I added the .desktop file to /usr/share/applications/screensavers/ but all I get when I select it is a black screen. On the GnomeScreensaver FAQ (here) it says to use a gsthemewindow as the toplevel window, but the libraries given are in C. Is there any way to:Import this C library to get access to this toplevel window, Convert this GTK+ C library to PyGTK, or use a pygtk app as a screensaver in some other way?

Debian Programming :: Implementing PyGtk For Python 3.3 In Wheezy

Sep 12, 2013

I run Wheezy Xfce 64-bit. I went through the Synaptic listings and added Python 3.3.2 and Tkinter for it, and that works fine; but for some reason PyGtk is available only for Python 2.7, not for Python 3.3, unless I'm just using the wrong way to try to find it. Is there a PyGtk available for Python 3.3 in Wheezy, and, if so, how do I install it and then import it once it's installed?

Programming :: PyGTK: Send Output From A File Descriptor To A Textview?

Jul 22, 2010

Within PyGTK I'm using gobject.spawn_async to launch a bash script. I would like the output of that bash script to be displayed within my application. I have a textview set up to receive the text ...

Here are the commands that launch the program:

def run_command(command):
global keep_pulsing
(cpid, cstdin, cstdout, cstderr) = gobject.spawn_async(command,flags=gobject.SPAWN_DO_NOT_REAP_CHILD|gobject.SPAWN_STDERR_TO_DEV_NULL,standard_code....

Here are the two callback functions. But like I say ... I have no idea how to get that data from the 'cstdout' file descriptor into a textbuffer.

textview = wTree.get_widget('textview1')
def update_textview_callback(fd, condition):
global keep_pulsing
if keep_pulsing:

Programming :: Can't Find Command, But Program Is Installed?

May 14, 2010

WindowsDude is back on the dark side of the web, the linux world, and he has encountered yet another impassable problem !There's a compiler mpicc, probably installed on the network at some location let's say /network/bin So when I write mpicc main.c I get the "can't find command" (or similar) error. Somehow it's supposed to work anyway. I think I need one of those magic commands to make it work. But the question is; which word will make it all happen? (I thought the DOS days were over!) I guess I could use the full path (provided that that binary really is in that folder), I want to bind that executable at that location to the much shorter mpicc.

How can you use:

Programming :: Create A Separate Thread For Program Which Basically Polls Using The Read Command?

Sep 28, 2010

I'm trying to create a separate thread for my program which basically polls using the read command. However this new thread seems to block the main thread, anyone know why this could happen.

In main I call this function pthread_create(&mainEventThread, NULL, GenericEventThread, NULL);

which calls
/*New threads start function */
void *GenericEventThread()
short int i, nError = -1;


I've used pthread_self to check that a new thread is being created, so why is the while loop in one thread blocking the main thread from running, I haven't used the join function anywhere in my code.

Ubuntu :: Launch A Program Onto Another X Screen?

May 11, 2011

This is for a live performance type of setup. I have 2 graphics cards. One is attached to 2 projectors, which are what the audience sees. The other has a single monitor, which is backstage. The 'front' graphics card is configured in Twinview, and the 'backstage' one is configured as a second X screen by the nvidia settings control panel.

What I'd like to do is launch my show program from a terminal on my backstage screen, but have it show up on the other X screen, the 'front' one. X is amazing so I'm sure it can be done, but I'm having a hard time figuring out exactly how.

Personal Best for self-solving my own thread question:

DISPLAY=:0.0; xclock
launches on display 0
DISPLAY=:0.1; xclock
launches on display 1

Ubuntu Installation :: Can't Access The .exe's What Files Launch A Program?

Feb 27, 2010

I'm completely new to the Linux OS. It is very foreign to me, i'm very used to the way windows does everything, including how windows does installation. I know that Linux doesn't understand .exe files like windows does... which is part of the problem. I have a linux zip file of a program (Jgrasp) that I want to install. I unzipped it into my home file and then wanted to run the program, but I have no idea what to do next. How the heck do I run the program if i can't access the .exe's what files launch a program in linux?Also how do i get it to recognize the JDK files?

Ubuntu :: Allow To Single Click To Open A Folder/launch A Program?

Mar 5, 2011

I've looked, but no luck. Coming from Debian, 5.02, is there a setting in Ubuntu 10.10 that will allow me to single click to open a folder/launch a program. I don't mean the one i am using now that is set up with the mouse setting where it seems to be an assistive technologies application where there is a slider to set the dwell time (when i use this one, i get a menu opening at the same time as the application launch), but the one where the pointer turns to a little hand when it moves over the icon, and opens/launches the program when the button is released.

CentOS 5 :: Compilation Of Gobject-introspection

Sep 21, 2011

I am trying to compile gobject-introspection-0.6.2in centOS 5.6 [Linux localhost.localdomain 2.6.39-4.el5.elrepo #1 SMP PREEMPT Thu Aug 4 19:58:19 EDT 2011 i686 i686 i386 GNU/Linux]. When i run ./configure it checks for all dependencies and run successfully but when i run i got a error <gio/gio.h> not found. but in fact i have set the GIO_UNIX_CFLAGS in the ./configure options. The configure command is ->

./configure GIO_UNIX_CFLAGS="-I/usr/local/glib/include/gio-unix-2.0

By observing the make errors, its obvious that <gio/gio.h> is not found which is in the directory /usr/local/glib/include/glib-2.0/gio and set through GIO_UNIX_CFLAGS variable.
