Customizing the JavaFX ProgressBar Component with CSS
Styling the ProgressBar component in JavaFX requires knowledge of its CSS classes and the specific CSS properties that affect its appearance. This guide will provide you with the necessary information to customize the color, background, and add custom text nodes to your ProgressBar.
1. Colorizing the Progress Bar
This can be done through the .bar class:
.progress-bar .bar { -fx-background-color: #yourColor; }
2. Setting the Background Color
Style the .track class:
.progress-bar .track { -fx-background-color: #yourBackground; }
3. Adding a Custom Text Node
Create a custom JavaFX Node that represents the text you want to display on the ProgressBar. Then, in your CSS, use the .knob class to position it:
.knob { -fx-text-fill: white; -fx-background-color: black; -fx-alignment: center; }
4. Changing the Progress Bar's Height
Use the .bar class to set the padding:
.progress-bar .bar { -fx-padding: 1px; -fx-background-insets: 0; }
5. Referencing the Default CSS
