问题描述
我想要一对取决于值的 TextField.并且y"值应根据空白进行调整.
I would like to have a pair of TextFields depending on a value. And the "y"-value should be adjusted depending on the empty space.
当值为 "0" 我想隐藏 TextField.
When the value is "0" I would like to hide the TextField.
即我想隐藏 staticText 和 textField 如果参数 red 等于 "0" 并且有蓝色值向上移动,在下面的 jrxml 代码中:
I.e. I would like to hide the staticText and the textField if the parameter red is equal to "0" and have the blue values moved up, in the jrxml-code below:
<staticText> <reportElement x="100" y="30" width="100" height="30"/> <text><![CDATA[Red items:]]></text> </staticText> <textField> <reportElement x="200" y="30" width="40" height="30"/> <textFieldExpression> <![CDATA[$P{red}]]> </textFieldExpression> </textField> <staticText> <reportElement x="100" y="60" width="100" height="30"/> <text><![CDATA[Blue items:]]></text> </staticText> <textField> <reportElement x="200" y="60" width="40" height="30"/> <textFieldExpression> <![CDATA[$P{blue}]]> </textFieldExpression> </textField>
输出示例:
//if blue = 3 and red = 2 if blue = 3 and red = 0 if blue = 0 and red = 2 Red items: 2 Blue items: 3 Red items: 2 Blue items: 3
这些文本字段将放置在我的报告的末尾.我该怎么做?
These TextFields will be placed at the end of my report. How can I do this?
推荐答案
<reportElement ...> <printWhenExpression><![CDATA[$P{red} == 0]]></printWhenExpression> </reportElement>
您可以使用 iReport 以令人愉悦的 UI 对其进行修改.
