= ForEveryRow =
:'''''(not yet implemented)'''''
== Syntax ==
:{{ForEveryRow: ((<compound-statement>))}}

== Return ==
:{{((true))}} if processing is complete for this row, else {{((false))}} if the {{((ForEveryPixel))}} handler should be called next for individual processing of each pixel in this row.

== Description ==
:If the {{((ForEveryTile))}} handler returns {{((false))}}. then this handler will be called for every row in the current tile, from top to bottom. This handler is a good place to call the {{((testAbort))}} or {{((updateProgress))}} function.

== Default handler ==
:The default {{ForEveryRow}} handler simply calls {{((updateProgress))}} to update the progress bar and test for an abort condition, and then returns {{((false))}}, passing control to the {{((ForEveryPixel))}} handler for every pixel in this row.

== Example ==
<code>
ForEveryRow: {
    updateProgress(row, rows);    /* update progress bar */
    return true;   /* processsing complete for this row */
}
</code>

== Also see ==
:((ForEveryTile)), ((ForEveryPixel)), ((handlers))

== Comments ==
:Everyone can add his/her comments about this handler here. Tips for using it are welcome, too.
