Hi all
I am a novice programmer in GTK.

Can anyone tell how to display an html page in GTK. I have tried GTKHtml and there few dependancy issues.

Any suggestions will help me.

Hi

Now I am able to launch browser window when I click the GNOME href new button. But I want to launch the browser when I select something in the GTK list box.

Code for GNOME href button
----------------------------------------------------------------------------------------------------------
#include <gnome.h>
GtkWidget * href1, *fixed1;

href1 = gnome_href_new ("http://www.ifpindia.org/", _("Visit IFP"));
gtk_widget_show (href1);
gtk_fixed_put (GTK_FIXED (fixed1), href1, 56, 152);
gtk_widget_set_size_request (href1, 216, 32);
-------------------------------------------------------------------------------------------------------
Suggestions will be very helpful.

Thanks
Iswaria.

Hi all
Gtkmozembed widget helps to embed browser in GTK.

Have anyone worked with gtkmozembed widget?

If so, please give the sample code.

Thanks
Iswaria.

As for GtkMozEmbed, i couldn't find and RPM and don't want to take the time to figure it out just right now, however, the API documentation is here: http://www.mozilla.org/unix/gtk-embedding.html

I was able to use gtkhtml3. I first had to install the development libraries which I did using yum:

Code: (Plaintext)
1	yum install gtkhtml3-devel

And then there is a tutorial on using the GtkHTML library here: http://primates.ximian.com/~rodo/programing_with_gtkhtml_tutorial/guadec.html

Hi
when I use the following code it is working fine.

Code for GNOME href button
----------------------------------------------------------------------------------------------------------
#include <gnome.h>
GtkWidget * href1, *fixed1;

href1 = gnome_href_new ("http://www.ifpindia.org/", _("Visit IFP"));
gtk_widget_show (href1);
gtk_fixed_put (GTK_FIXED (fixed1), href1, 56, 152);
gtk_widget_set_size_request (href1, 216, 32);
----------------------------------------------------------------------------------------------------------

When I change the website address to local address "file:///home/OscarDesktop/Images/especes/b/brare/brare.html" the following error occurs:

An error has occurred while trying to launch the default web browser.
Please check your settings in the 'Preferred Applications' preference
tool.
Please suggest.

Thanks
Iswaria.

It looks as though it's not using the file:/// to mean web browser. Perhaps you can use a call to something like system("firefox file:///blablabla") or perhaps there is a way to get the default web browser and then call it using system or one of the exec functions?

Better yet, use GConf to add a handler for "file:". You can copy the one for http and just replace the http: with file:

Code: (Plaintext)
1 2 3 4	/desktop/gnome/url-handlers/http: needs_terminal = false command = firefox %s enabled = true

See http://www.gnome.org/projects/gconf/ for information on GConf. The API library for GConf is at http://developer.gnome.org/doc/API/2.0/gconf/index.html

Hi Micah Carrick
Thanks a lot.

System command is working to launch the browser.

system ("firefox file:///home/OscarDesktop/Images/especes/b/brare/brare.html");

Thanks

Great... the only problem is that your users will have to have firefox in order for that to work. But if you're just using it for yourself... that'll work just fine.

Hi
Is it possible to say the default browser in the user computer instead of specifying firefox? We can't assume all the users will have firefox.

Thanks
Iswaria.

If it's a gnome application, then you can use GConf to determine which is application "handles" firefox. I don't know how it would work with KDE or other environments. You may also want to have a preferences dialog in you application in which the user specifies their browser... or programatically check for several of the more well known browsers.
