RE: gtk-list Digest, Vol 29, Issue 53

Hi
	I am a new GTK+ user, I have a small problem if any one can help
me I will be happy.
How to link a url say something like "www.google.com" from my gtk
program.

The situation is like, I have created a small window and there is a
button "search". If we click the search button I need to open a google
home page.

I have searched and I got something with python.Since I am doing all the
things in C.
So please help me by providing some info on the same.
In my program I am using only gtk+2.0.

Thanks and regds,

With regds,

Shyjumon N

	Hi,

	First of all, apologies if this has already been covered on this
list 
but the archive search is down.
	I have a GTK application that works under Mac OS X. My goal is
to be 
able to run this program from a Mac 'bundle'. I have been able to gather

runtime files for GTK and I can start the program from a shell script 
that sets the DYLD_LIBRARY_PATH. I have now been able to use the 
'install_name_path' to alter the dynamic library links for my program to

point to relative links in a bundle (Contents/Frameworks). If I run the 
program via SSH (and X11 forwarding is on) I am able to run my program 
without needing the shell script. Great.
	That is until I try running the bundle from within Mac OS X
itself. The 
problem comes when the program starts it doesn't have any 'DISPLAY' 
environment variable and gtk_init_check returns false. Now, my program 
is built to be run either with GUI or without, so it goes and sits in 
non-gui mode. :/ .. So, I can run my program from a bundle within Mac OS

X, I just can't get it connected to X.
	I tried running X11 before starting my program. No change. I
tried not 
having the X libraries within my application's bundle. No change, still 
don't get a display. If I set the display variable within a Mac OSX 
'Terminal' and X11 is running, my program starts up great.
	So, question is, how do I get Mac OS X to a) start X11 for me,
and b) 
provide my program the equivalent of the 'DISPLAY' variable so 
gtk_init_check will be happy there's an X display there and all will 
come to life?
	I'd appreciate any help about it. This may not even be the
correct list 
to ask such things on (since it's a big Mac related) but since I'm using

GTK for my cross-platform GUI, I thought I'd ask).

	Thanks,

	Derek

Hello All,

I am testing my tool (see signature) under MEPIS Linux now (kinda
UBUNTU), so,
obviously, I need to install some development packages at system level.

Interestingly enough, 'configure' completed successfully, but 'make'
failed
- because Xrender.h file was missing - here is the file which requires
it:

/mnt/hdd2/sergei/build/gtk+-2.8.20/gdk/x11/gdkdrawable-x11.h:#include
<X11/extensions/Xrender.h>
.

I expect 'configure' to check presence of all needed include files, and
to fail if
any of them is missing.

Is my expectation correct ?

If yes, isn't it a big in 'configure' of gtk+-2.8.20 ?

Thanks,
  Sergei.

Hello! Can anyone kindly clarify when to use gtk_widget_set_events() 
routine? I know every widget has some default events. But how can we be
sure 
which events are automatically selected by widgets and we don't need to
call 
the above mentioned routine? Thanks.

Use  Gimp.app approach. They wrapped their application in a shell
script.
The script launches the x11 terminal, catches the  display, and then
executes the  program ( after setting required env values ) . They also
detail how to package it on their website:
http://gimp-app.sourceforge.net/

This is the approach I use to bundle gtk with my MAC OS X distro - and
the
method of launching. I've been told it works on both Panther and Tiger
versions of OS X without a glitch.

Essentially never.  Use gtk_widget_add_events() to add
events.  Removing default events typically breaks widgets so
you rarely need it (and even then it should suffice to
prevent the particular event handler from running by
handling the event yourself).

Wasn't there a native port for Gtk on MacOS X?

there is. its usability varies depending on your application. we (the
ardour project) can't use it yet - it is still too unstable and there is
missing functionality. i wish someone would fund serious, aggressive
development of gtk-aqua because it would help out *so* many development
efforts.

Thanks Yeti. That's all I wanted to know.

No.  Usually a 'configure' script will run a test case that checks for
*one*
file that indicates something is installed.  Apparently, it looks for
some
other file to detect whether the Xrender extension is present and
usable.

What does the config.log say for the Xrender check(s)?

AFAIK it checks only whether -lXrender makes function
XRenderQueryExtension available and does not check for any
Xrender header file at all.

In other words it doesn't anticipate modular Xorg where
Xrender is a separate library (like everything else) and
it's possible to have any combination of the libraries and
header files installed.  For example on Fedora one would get
to this situation by installing libXrender but not
libXrender-devel (although this is not possible without
removal of lots of other Gtk+ dependencies therefore
configure would not pass there).

IMO it should test the presence of header files for each
extension it needs and I suggest to report it as a bug (if
it isn't in bugzilla already).
