I tried to do an application with TEdit,TButton  who works like the  Mozila Navigator. I want that when I enter an URL in Edit1 and click on this Button, the web page will load  in the application. I managed to do it on Delphi but not on Kylix. Could anyone help me, please? Thank you.

The Delphi system will very likely add an IE control to your application. Linux does not support controls like this, which means that you have to do this manually. You need to add e.g. the Mozilla rendering engine 'Gecko' to your application and call it whenever you need the browser.

However, this is not how things are usually done in Linux. THe standard approch to this is to call an external browser and just hand off the URL you want to display.

So, welcome to the wonderful world of Linux programming :-)

I'm not familiar with Kylix, so the real work is up to you ;-) You can probably call an external program (with something like a system() call). Once you know how to do that, you need to find out which browser to call. Because there is not just one browser, the most straight forward approach is to let your users configure which browser to use. There are a few browser locations you can try first if you don't have a specific path configured:

/opt/kde3/bin/konqueror
/opt/mozilla/mozilla
/usr/local/mozilla/mozilla

hi,
a better way is to look, how the browsers in linux are made. See the source codes. But that wont be so easy.
http://www.mozilla.org/source.html

galeon was made using features of mozilla. see its codes to know how to call functions of mozilla.
http://galeon.sourceforge.net/download/

> .. the web page will load  in the application ..
if you mean that the HTML code should be rendered, see previous comments.
If you mean that you just want to display the text, then the usual way is somehow like (pseudo code):
  open(FILEHANDLE, "web page" );
  read( FILEHANDLE );
  write( FILEHANDLE );
;-)
