Is it possible to add a button in the report, which any action will be fixed?

Example: Button \"View\", which will show more detailed statistic.

To create a button, create a textField with hyperlinkType="Reference" and a hyperlinkReferenceExpression

Example




    <band height="80" splitType="Stretch">
        <textField hyperlinkType="Reference" hyperlinkTarget="Blank">
            <reportElement mode="Opaque" x="150" y="20" width="200" height="40" forecolor="#FFFFFF" backcolor="#009900" uuid="822deecb-059b-4921-bfb7-07ee7cbde26a">
                <property name="net.sf.jasperreports.export.html.class" value="btn"/>
                <property name="net.sf.jasperreports.export.html.id" value="idBtn"/>
            </reportElement>
            <textElement textAlignment="Center" verticalAlignment="Middle">
                <font size="24"/>
            </textElement>
            <textFieldExpression><![CDATA["VIEW"]]></textFieldExpression>
            <anchorNameExpression><![CDATA["myButton"]]></anchorNameExpression>
            <hyperlinkReferenceExpression><![CDATA["https://stackoverflow.com/users/5292302/petter-friberg"]]></hyperlinkReferenceExpression>
            <hyperlinkTooltipExpression><![CDATA["Click to view"]]></hyperlinkTooltipExpression>
        </textField>
    </band>

Will generate

when clicked it will direct you to the value of the hyperlinkReferenceExpression, in example I have also set hyperlinkTarget="Blank" so it opens in a new page.

For additional information on the attributes see JRHyperLink API

Hey I want my button to change color when I pass over it....

No problem, (as long as export is html, in pdf you need to do some tricks with annotation but I will leave this out..).

I have added some css tags on the textElement see the property under the reportElement
