Hybrid of slider with progress bar JavaFX
提问by Vetalll
I want to handle click on ProgressBar like on slider. and learn a percent of track. I would use slider instead progressbar but it doesn't have a highlighted track until thumb.
我想像在滑块上一样处理对 ProgressBar 的点击。并学习百分之一的曲目。我会使用滑块而不是进度条，但直到拇指时它才具有突出显示的轨道。
I need create something like a progress in a music player of playing song, and possibility to seek with a click on progress.
我需要在播放歌曲的音乐播放器中创建类似的进度，以及通过单击进度来寻找的可能性。
Do anybody have a tips how can i do it?
有没有人有提示我该怎么做？

Here is another approach. Real hybrid of slider and progress bar :). Meet SlidoProgressBar!
这是另一种方法。滑块和进度条的真正混合体:)。认识 SlidoProgressBar！
public class SlidoProgressBarDemo extends Application {
@Override
public void start(Stage stage) {
Group root = new Group();
Scene scene = new Scene(root);
scene.getStylesheets().add(this.getClass().getResource("style.css").toExternalForm());
stage.setScene(scene);
stage.setTitle("Progress Controls");
double sliderWidth = 200;
final Slider slider = new Slider();
slider.setMin(0);
slider.setMax(50);
slider.setMinWidth(sliderWidth);
slider.setMaxWidth(sliderWidth);
final ProgressBar pb = new ProgressBar(0);
pb.setMinWidth(sliderWidth);
pb.setMaxWidth(sliderWidth);
final ProgressIndicator pi = new ProgressIndicator(0);
slider.valueProperty().addListener(new ChangeListener<Number>() {
public void changed(ObservableValue<? extends Number> ov,
Number old_val, Number new_val) {
pb.setProgress(new_val.doubleValue() / 50);
pi.setProgress(new_val.doubleValue() / 50);
}
});
StackPane pane = new StackPane();
pane.getChildren().addAll(pb, slider);
final HBox hb = new HBox();
hb.setSpacing(5);
hb.setAlignment(Pos.CENTER);
hb.getChildren().addAll(pane, pi);
scene.setRoot(hb);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
with style.css:
使用 style.css：
.slider .track {
-fx-background-color:null; /* Hide the track */
-fx-background-insets: 1 0 -1 0, 0, 1;
-fx-background-radius: 2.5, 2.5, 1.5;
-fx-padding: 0.208333em; /* 2.5 */
}
The basic logic is to put slider and progress into stackpane. Give them the same width. Bind the progress values of them. Hide the track of the slider.
Output:
基本逻辑是将滑块和进度放入堆栈窗格。给它们相同的宽度。绑定它们的进度值。隐藏滑块的轨迹。
输出：

i solved this problem with code :
我用代码解决了这个问题：
progress.setOnMouseClicked(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent event) {
if (event.getButton() == MouseButton.PRIMARY){
Bounds b1 = progress.getLayoutBounds();
double mouseX = event.getSceneX();
double percent = (((b1.getMinX() + mouseX ) * 100) / b1.getMaxX());
//correcting a percent, i don't know when it need
percent -= 2;
progress.setProgress((percent) / 100);
//do something with progress in percent
}
}
});

Just a tornadoFX example:
只是一个 tornadoFX 示例：
package bj
import javafx.application.Application
import javafx.geometry.Insets
import javafx.scene.control.ProgressBar
import javafx.scene.control.Slider
import javafx.scene.paint.Color
import tornadofx.*
/**

class MainView : View() {
private lateinit var progressBar: ProgressBar
private lateinit var slider: Slider
override val root = vbox {
stackpane {
padding = Insets(100.0)
progressbar(initialValue = .0) {
progressBar = this
maxWidth = Double.MAX_VALUE
}
slider(max = 1, value = .0) {
slider = this
}
}
}
init {
progressBar.progressProperty().bind(slider.valueProperty())
progressBar.paddingLeftProperty.bind(progressBar.heightProperty().divide(2))
progressBar.paddingRightProperty.bind(progressBar.heightProperty().divide(2))
}
}
class MainStylesheet : Stylesheet() {
init {
slider {
track {
backgroundColor = MultiValue(arrayOf(Color.TRANSPARENT))
}
}
}
}
class App : tornadofx.App(MainView::class, MainStylesheet::class)
fun main(args: Array<String>) {
Application.launch(App::class.java, *args)
}
