    <p><strong>What I Need to achieve</strong><br> I have a huge set (around 1 million) of records (each records of 500 bytes) on disk (a specific file) with below format </p> <pre><code>=========================================================== |X|a,b,c|O|m,n,g|X|t,a,c|X|e,p,q|O|u,q,p|X|r,t,s|O|l,m,a| =========================================================== </code></pre> <p>The first field consist of flag ('X') represents valid filled data, flag ('O') consists of structured data. For example, first set contains a valid data with a,b,c as its data (assume of a structure).</p> <p>I need to display them on screen (linux) more like the <code>top</code> command output (in terms of simple - meaning keyboard input driven, dynamic GUI - like refresh, page-down options etc) like - </p> <pre><code>Display Record From No XXX Records Number Field 1 Field 2 Field 3 1 a b c 2 NA NA NA 3 t a c 4 o p q 5 NA NA NA 6 r t s 7 NA NA NA F5 [Referesh] Page-Down [Next Page] Page-Up [Prev Page] Ctrl+C [Exit] </code></pre> <p>Where the value XXX, would be entered by user and one page of records are shown. </p> <p><strong>Questions</strong> </p> <p>a. Since the display is similar to that of top/ atop command, Can you please let me know the base on which such commands are displaying the output? </p> <p>b. Any specific language (like GTK,QT etc) which are more suitable for such operations? Basically any better language apart from the one used in top/atop command. (May be this question is subjective) but would like to collect best opinion? </p> <p>c. Now, if I want to template the structure (by providing in config file) so that different kinds of structures can be read and displayed, From which language is this best possible? Note : Here I mean, file 1 contains structure A data only. file 2 contains structure B data. So while reading file 2, I would like to load the structure configuration of Structure B and run the tool for display. </p> <p>PS :<br> The above files are in-fact written to file with a normal C application (hinting the structure and its fields would be of C basic data type attributes).</p>

    3. COGTK+ and Qt are not "languages", they're user interface toolkit libraries. At least GTK+ can be used from a great number of different programming languages (through "bindings").

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
