table-row -> onCreate -> set row style?

roopurt81

Greetings,

I have a style in my report named "highlight-table-row." In my detail row's onCreate() handler I'd like to apply this style via the style name. I was thinking something like:

// this is the table row
this.setNamedStyle( "highlight-table-row" );

I can't seem to find any method that would accomplish this.

The best I can do is:
this.style; // IScriptStyle instance, which lets me look at all of the properties

I tried looking around in the object returned by:
reportContext.getDesignHandle();
There's some hope there because I can find report styles by name. But then I'd have no idea what's the best way to apply the styles to the row.

Any help is appreciated!

I thought I'd post a reply with a bit more context and what I'd settled on since I can't figure out how to do exactly what I want.<br />
<br />
I'm creating a set of generic reports for a new product. I'm using a report library to store the report styles and themes so I can easily change all reports if necessary. In my library I have a style named "highlight-table-row" and the only property that is not default is backgroundColor.<br />
<br />
One of my reports is a listing of transactions sorted by an associated vehicle. The report is much easier to read if alternating vehicles are highlighted. Ideally when it was time to highlight a row, I would have liked to say:<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>row.setStyleName( "highlight-table-row" );</pre>
But there is no such method. A highlight rule may have worked because you can set a style for a highlight rule. However my logic for determining the highlight occurs in table-row.onCreate() and the highlight rule is applied <em class='bbc'>before</em> my logic occurs, so the row highlights end up incorrect.<br />
<br />
Anyways, here is what I came up with.<br />
<br />
In my report's initialize() event:<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>// Set tracking object
g_tracker = {
// Highlight flag. True if highlight is applied, false otherwise.
highlight : true,
// Current value from column that is being watched.
value : null,
// Name of the column to watch in the table.
column_name : "vehicle_cd",
// The style to apply when highlighting is in effect. Change the string
// argument to the name of the appropriate style.
style : reportContext.getDesignHandle().findStyle( "highlight-table-row" )
};

/**
* Call this in table detail onCreate(), as such:
* table_row_create( this ); // this is the table row
*
* @param table-row
*/
function table_row_create( row ) {
// Row's data
data = row.getRowData();

// The value for this row
value = data.getColumnValue( g_tracker.column_name );

// Do not attempt to use !== or != for this comparison.
// It compares the objects and not their values!
if( BirtComp.notEqual( value, g_tracker.value ) ) {
g_tracker.highlight = ! g_tracker.highlight; // Toggle highlight value
}
if( g_tracker.highlight === true ) {
// TODO ADD LINES FOR ADDITIONAL PROPERTIES IF NECESSARY
// UNTIL BIRT HAS A SETSTYLE( “NAME” ) METHOD.
row.getStyle().setBackgroundColor( g_tracker.style.getBackgroundColor().getStringValue() );
}
g_tracker.value = value;
}</pre>
<br />
And in the table-row.onCreate() event:<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>table_row_create( this );</pre>
<br />
If anyone can offer any pointers or tips so that I can achieve my goal, I'd still appreciate it.
