HGridPagedOutput
public class HGridPagedOutput extends GenericOutput (Code)
Prints recordset in tabular format using horizontal direction, meaning that each row from the recordset will fill a cell until the maximum nimber of cells is reached, then a new row will be appended to the table. It may be used to print products catalog with pictures and things like that.

This class also supports paged views, which are ideal for creating thumbnails or galleries.
The Actions using this class are supposed to be INCLUDED by other Actions, using the include marker ${inc:/action/xyz?param=value}, it was not designed to produce a complete page, just a part of it, a grid with horizontal data direction, to be more specific. Actions using this Output class must define the following elements in config.xml, under the root element:

<row-template>row.htm</row-template> <col-template>col.htm</col-template> <cols>3</cols> <hgrid-recordset>myRecordset.sql</hgrid-recordset>

Of course you can adjust these elements's values to meet your requirements.

Most of the time, the Action using this Output class will require only one recordset, which must be created by the parent Action (the one that includes the others) and saved into a request attribute, which means that this class must retrieve the recordset from the request object.

This class requires a basic template (defined in the output block in config.xml), like any other text-based output that inherits from dinamica.GenericOutput, invokes super.print() before proceeding to create its own output. This template should contain the surrounding HTML code for the table, and a dummy marker named ${hgrid} where the actual generated HGrid will be printed.
