Dynamic color in TextField in Jasper reports

Navigation
0

I want to change the color of the textfield according to the value of it, I found several tutorials that say to create a style and apply to the textfield, have to select a "styled text" option that I did not find in the textfield properties in jasper, the tutorials all refer to Ireport and I use JasperReports, any tips?

If you can not find it, another possible solution is to overlay another textfield with the color you want and switch to show one or the other:

I've been through this same problem, I needed to paint each line of the red report pair, so I found the following solution: 

<style name="style_fundo_vermelho" mode="Opaque">
        <conditionalStyle>
            <conditionExpression><![CDATA[new Boolean($V{REPORT_COUNT}.intValue() %2 == 0)]]></conditionExpression>
            <style backcolor="#FF0000"/>
        </conditionalStyle>
    </style>

Here in this section I create the Style that has a Boolean condition:

(if the counter number of the line divided by 2 is = 0 then it is a even line and its background will be red) 

new Boolean($V{REPORT_COUNT}.intValue() %2 == 0)

After creating this style with the name = style_background I add it to the style attribute of textField: 

<textField>
    <reportElement style="style_fundo_vermelho" x="658" y="1" width="90" height="16" uuid="c118ccc6-4074-4f03-9bfa-cf6c3ae8a1b9">
    </reportElement>    
</textField>

So you can solve your dynamic background color problem in text field by simply adapting style to your need.
