如何在javafx中更改窗格的颜色? [英] How to change the color of pane in javafx?

问题描述

我想更改用户从String获得的Pane的颜色. 如何在窗格中将此String设置为背景颜色?

I want to change the color of a Pane which I get as a String from user. How can I set this String as a background color in my pane?

代码:

colorField.setOnKeyTyped(new EventHandler<KeyEvent>() {
    @Override
    public void handle(KeyEvent t) {
        color = colorField.getText();
    }
});

推荐答案

如果您真的只是想知道如何完成那特定的事情，我建议以下几点:

If you really just want to know how to accomplish that particular thing, I'd suggest the following:

设置节点 CSS ，使用 hexacolor 由用户输入:

Set the Nodes' CSS like this, using the hexacolor that was entered by the user:

String enteredByUser = "abcdef";
yournode.setStyle("-fx-background-color: #" + enteredByUser);

如果您想了解更多信息，请更具体地回答问题，并提供一些代码示例.

If you want to know more please be more specific with you questions and provide some code samples.

由于您用"javafx-8"标记了这个问题，因此我还将提供该代码示例(仅适用于javafx 8):

Since you tagged this question with 'javafx-8' i'll provide that code example as well(only works in javafx 8):

yournode.setBackground(new Background(new BackgroundFill(Color.web("#" + enteredByUser), CornerRadii.EMPTY, Insets.EMPTY)));
