Re: Problem with installing GTK+-2.0.0 on Fedora Core 6

there is a "gtk_timeout_add" (the new name is "g_timeout_add"). Maybe this one?

2009/5/11 Adeel Malik <adeelmalik78 yahoo com>:

The structure of my code is that when I click on the 'start button', the
callback function needs to continuously acquire data from a daq card in a
while loop, a functionality that I am not supposed to change. Now I want to
send a refesh signal to control (during the course of button callback
function) and one way to do this it toÂcall a g_timer_add function which my
current gtk_installationÂ(gtk 1.2.10) doesn't support.

It looks like you've already asked the question before:
http://mail.gnome.org/archives/gtk-app-devel-list/2009-March/msg00115.html
as I understood, you have "Main Loop" (read about it in Gtk and
GLib),
a thread which get data from your "stuff" and calculates the average
value.

So, don't try to make main loop runs faster than it is. maybe you
should send a refresh (or repaint, update) signal to your control.
what do you think ab. it?

Hi,
ÂÂÂÂÂ The main gtk thread needs to refresh an image widget (for

status

indication, GREEN or RED) along with a couple of 'status

variables'

e.gÂBlock/Symbol error rate using labels. There is a start button in the

GUI

associated with a data acquisition routine that computes the value of the
aforesaid variables and in a busy while loop. All I want is to compute the
average varibale value, say for last 1000 iterations, and display on the

GUI

after every 100 ms or so.
cheers,
Adeel

Hello,

What is the purpose of your update? Do you want to refresh a widget,
or anything else?

Hi, I was wondering how to update the gtk_main_thread function after a

fixed time interval (in milliseconds)Âas g_timer_add function provides a
quick
solution to that. Could someone suggest how to go about it ?.


Thanks,
Adeel

One of GTK+ dependency is GLib, each GTK+ version has it's GLib

version

dependency too, if you try to compile a newer GTK+ version in a system

that has

not meet it's minimal requirement of GLib version then they will

complain.


You tried to update GLib on your distro using a package manager, you

will

got

nothing to do because your distro will not broke all dependency that

it

already

made. Moving from 2.4.0 to 2.12.3 is not trivial, this will break many
applications that already installed, so they must have to update all
applications to meet the new dependency. Distributor tend to release a

new

distro version rather than rebuild and update applications in the

their

current

version.

g_timer_add()? i don't know if this was a obsolete function, but i

think

there are a lot way to write codes such this function does. I

can't

see a

reason why you should move to a version of GTK+ because of this

function!

Hi All,
ÂÂÂÂÂÂÂ I am doing application development on Fedora Core 6

Linux

machine which had GTK version 1.2.1 already installed. I needed to use
g_timer_add gnomeÂfunction in my gtk application which doesn't

seem

to be

supported on this version. So i tried to install the newer version of

GTK+-2.0.0

from the gtk.org web page.
Once I copied tar.gz file and tried to install the app. by running the
'./configure' script, the insatallation process stopped at the

following

error messages:




---------------------------------------------------------------------------------------------------------------------------------

checking for GLIB - version >= 2.0.0...
*** 'pkg-config --modversion glib-2.0' returned 2.12.3, but

GLIB

(2.4.0)
*** was found! If pkg-config was correct, then it is best
*** to remove the old version of GLib. You may also be able to fix the

error

*** by modifying your LD_LIBRARY_PATH enviroment variable, or by

editing

ÂI treid to update the glib library by running:

'yum update glib'Â or 'yum install glib' but it

appeared

that

kernel couldn't find the match and issued the following

messages:

---------------------------------------------------------------------------------------------------------------------------------

I was wondering whether the problem is with the 'yum' package

as

it is

unable to find the requestedÂGlib library. Since the whole point of

installing

the new version of GTK was to be able to use the 'g_timer_add'
function, can some one suggest if it is possible to use this function

with

the

GTK 1.2.1 version. If not, can someone point out how can I fix the

installation

error if GTK+-2.0.0.

Thanks,
Adeel
