Discussions in this context is more about discussing technical problems/issues and how to solve them. General discussions about "why I think application X is good", or "why product Y sucks" are usually ignored, or taken to the Lounge.

As you may have noticed that, apart from me and Albert, no one has joined in.

Lounge is a place for non-programming discussion.

rule 2 in rules for the Lounge :
- No programming questions. For quick answers to your questions please use Quick Answers, for technical discussions use the programming forums(Discussions)

Please read rules carefully.

I had a short contract job where we used the qt framework in all of our c/c++ development. We didn't actually use the IDE though just the framework. The development was done on the linux commmand line. Was there something you wanted to know about it?

I'm new in linux. and I want to develop a application for embedded devices too.
Do you suggest me to use qt framework ? or to write my one framework with linux api?

thnx

I guess it depends what type of embedded programming you are doing. But I would say I had a pretty positive impression of it. The framework was very comprehensive. It seemed like literally anything you could think of existed in qt. This included even standard objects. For instance there's qstrings, qmakefiles, qxml ect... . I would recommend if you use qt that you use the Qx or QTx version of things because everything in qt is designed to work together it seems like. In general the QT version will tend to be similar or simplified from the standard c/c++ library version of things.

We were doing linux programming for a custom linux based thin client OS and for some of the server software to control the thin clients so if you are doing an embedded linux application it should be a good choice.

First thank you for your good explanation about qt. but do you have any experience with qt on arm?

No we were using Intel chips but there were plans to move to ARM. I wouldn't think that anything would be different though. QT is designed to be cross platform. Also I think Nokia did a lot of the development of QT for their cell phones and since most cell phones use ARM I'd be suprised if ARM wasn't thoroughly supported.

Along with the Nokia ownership involved, should be noted the framework is NOT free to be used commercially. Just something worth noting.

Qt is very versatile, one of the biggest positives is it's ability to go across multiple platforms. With that said, if it's a commercial application there may be fees to pay to Nokia, go to their website for pricing info (it's not published, you have to request it).

master page of include?

19-Nov-11 5:48

if you had an option to:

1. create a master page and then use to put the full content of the page...

or:

2. to have a coded page with table but use include to include the navigation menu, top header and footer?

which one you'll prefer and which one you'll recommend?

Hi,

The method will be chosen based on your design. But i always prefer to the second method.
Since if all the web pages are exactly not similar, and if you want to customize some pages, second method will be good..

I use includes with function calls.

file structure might look like...
/index.php
/main_inc.php
/template/header.php
/template/menu.php
/template/footer.php

index.php and most other pages would look like this...

<?php
include(main_inc.php);
//*************************** index content start

//*************************** index content end
footer($pg_name); // attrib is set in main_inc.php and can be called here
?>

main_inc.php. $pg_name is obtained automatically

<?php
// if using a session start here, otherwise ignore this and the next line.
session_start()

$pg_name = substr($_SERVER['SCRIPT_NAME'],strrpos($_SERVER['SCRIPT_NAME'],"/")+1);
include('/template/header.php');
include('/template/footer.php'
?>

The header file....

<?php
/*
   this should be local to the header file, if it does not work add the '/template/' to the start of menu.php
*/
include('menu.php');
pg_init($pg_name);
pg_header(pg_name);

function pg_init($pg_name)
{
   // set session or global variables related to this page...
}

function pg_header($pg_name)
{
   // if using global init vars reference them here, should not matter for sessions
   echo "<html>";
   echo "<head>";
   echo "<title>".$pg_title."</title>"; // from an init var
   // add script or even style data as needed. Because you are passing the page name you can load just what you want for the page.
   echo "<script>...</script>";
   echo "<style>...</style>";
   echo "</head>";
   echo "<body>"; // you can also include body onload/onunload events to the body tag based on page..if your into that sort of thing ;)
   pg_menu($pg_name);  // remember the include for the menu.php above...well here you call the function inside of it.
}
?>

The menu.pgp page

<?php
function pg_menu($pg_name)
{
   // logic to display menu and highlight current page.
}
?>

The footer.php page

<?php
// close up the page and if need be add special code for specific pages...like javascript added to the bottom of a page.
function pg_footer($pg_name)
{
echo "</body>";
echo "</html>";
}
?>

This whole thing could be done without using function calls, but I like the parameter passing and with more thought I can add some security, input checking, page name validation, and more and more...

this is a fairly simple template but very flexible

Please create a DIV with 100% width and height. Then inside this DIV create another DIV with 100% width and specified width. Then position this DIV by using margin-top, margin-bottom, etc... Hope this will help you..

What do you want to learn about Red Hat?

To begin with, I'd start playing with Fedora (based on the same code). They're a community supported project (versus Red Hat which is mostly commercial) which offers plenty of help, everything from forums to live chat support.

Fedora links:

Red Hat has a "Certified System System Administrator" certificate. The books for studying for the certificate are the best all around Unix/Linux books available.

Fedora Core 16 is now systemd for boot up, which has made most books obsolete.

Download Fedora Core, it is their cutting edge software for the Enterprise systems.

Hi,

when you add a link in your Linkedin or facebook it will automatically determine the page title.. and when I say the title I don't mean the mata tag title but the real page title, that's what I have noticed.... so how can i do this using PHP?

Thanks,
Jassim
