Textarea javaFx Color | 易学教程

问题

Am trying to develop an app that looks like a terminal console, am using a TextArea for that and my wish is to habe a black background and green text,

the point i want to do this without using any ccs template

I know that my question can look like a duplicated in here:

javafx textarea background color not css

JavaFX CSS styling of TextArea does not work

but after reading those and trying what they suggested I found no luck to solve my issue

What I tried so far:

in the FXML:

<TextArea 
    fx:id="terminalTextArea"
    layoutX="14.0"
    layoutY="85.0"
    prefHeight="64.0"
    prefWidth="402.0"
    style="-fx-font-family: Consolas; -fx-highlight-fill: #00ff00; -fx-highlight-text-fill: #000000; -fx-text-fill: #00ff00; -fx-background-color:#000000;"
    text="Terminal"
    AnchorPane.leftAnchor="10.0"
    AnchorPane.rightAnchor="10.0">
    <font>
        <Font name="System Bold" size="14.0" />
    </font>
</TextArea>

but no luck ....

and in the source-code:

@Override
public void initialize(URL url, ResourceBundle rb) {
    System.out.println("init here");
    terminalTextArea.setStyle("-fx-text-fill: black;");
}

the only thing that I get is a bordered color like in the image below....

does any one of you had the same problem before????

Tnxs in advance

The recommended way is to use an external CSS file, as in the examples you linked.

If for some reason you don't want to do that, try

style="-fx-control-inner-background:#000000; -fx-font-family: Consolas; -fx-highlight-fill: #00ff00; -fx-highlight-text-fill: #000000; -fx-text-fill: #00ff00; "

in your FXML file, or equivalently

terminalTextArea.setStyle("-fx-control-inner-background:#000000; -fx-font-family: Consolas; -fx-highlight-fill: #00ff00; -fx-highlight-text-fill: #000000; -fx-text-fill: #00ff00; ");

in your controller's initialize() method.

SSCCE:

StyledTextArea.fxml:

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.layout.HBox?>
<?import javafx.geometry.Insets?>
<?import javafx.scene.control.TextArea?>
<?import javafx.scene.text.Font?>

<HBox xmlns:fx="http://javafx.com/fxml/1" >
    <padding>
        <Insets top="12" left="12" right="12" bottom="12"/>
    </padding>
    <TextArea 
        prefHeight="64.0"
        prefWidth="402.0"
        style="-fx-control-inner-background:#000000; -fx-font-family: Consolas; -fx-highlight-fill: #00ff00; -fx-highlight-text-fill: #000000; -fx-text-fill: #00ff00; "
        text="Terminal">

        <font>
            <Font name="System Bold" size="14.0" />
        </font>
    </TextArea>
</HBox>

and a test class:

import java.io.IOException;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class StyledTextArea extends Application {

    @Override
    public void start(Stage primaryStage) throws IOException {
        primaryStage.setScene(new Scene(
            FXMLLoader.load(getClass().getResource("StyledTextArea.fxml"))
        ));
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

It's simple, just put an id name inside the elment you want like:

AnchorPane id="AnchorPane" prefHeight="180.0" prefWidth="430.0"

or in Scene Builder in properties just down below the title JavaFX CSS write the name and style this element in your CSS file.

回答3:

if you are trying to set the background of textArea using CSS, you should have this attributes of CSS .content . viewport //additional .scroll-pane

Codes:

#tContent{
    -fx-pref-width: 180;
    -fx-pref-height: 110;

}
.content {
    -fx-background-color: transparent;
}
.viewport{
    -fx-background-color: transparent; 
}
