JavaFX:如何更改行颜色?

JavaFX:如何更改行颜色?,java,javafx,Java,Javafx,需要更改tableview控件中的行背景色 但是,如果我按行工厂更改它(使用setStyle),它也会更改选定行的颜色背景行颜色 怎么把它分开 我的代码片段如下: package javafxapplication1; import javafx.application.Application; import javafx.beans.property.SimpleIntegerProperty; import javafx.beans.property.SimpleObjectPrope

对于(int i=1;i而不是
-fx背景色
,偶数行使用
-fx控件内部背景
,奇数行使用
-fx控件内部背景alt

    String style = "-fx-control-inner-background: linear-gradient(#007F0E 0%, #FFFFFF 90%, #eaeaea 90%);"
            + "-fx-control-inner-background-alt: linear-gradient(#007F0E 0%, #FFFFFF 90%, #eaeaea 90%);";
另外,在外部css文件中执行此操作要干净得多:

application.css:

.table-view .table-row-cell {
    -fx-control-inner-background: linear-gradient(#007F0E 0%, #FFFFFF 90%, #eaeaea 90%);
    -fx-control-inner-background-alt: linear-gradient(#007F0E 0%, #FFFFFF 90%, #eaeaea 90%);
}
然后

scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());

现在您可以完全摆脱
行工厂

使用JDK 8u60 EA,这会导致许多异常,如:警告:捕获的'java.lang.ClassCastException:javafx.scene.paint.LinearGradient无法转换为javafx.scene.paint.Color',同时转换样式表jar中规则'*.table row cell'中'-fx text fill'的值:file:/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/jre/lib/ext/jfxrt.jar!/com/sun/javafx/scene/control/skin/modena/modena.bssAh,是的:的确如此。(尽管如此,它似乎仍然有效。)我很懒,只是用固定的颜色而不是渐变来测试。对于渐变,除了为
:selected:focused
:selected
、和
:focused
重新创建值之外,可能没有其他方法可以做到这一点,这有点乏味。让我想想。。。
