Examples with WeakEventHandler javafx.event.WeakEventHandler used on opensource projects

Example 1 with WeakEventHandler

use of javafx.event.WeakEventHandler in project Board-Instrumentation-Framework by intel.

the class VuMeterSkin method initGraphics.

private void initGraphics() {
    hBox = new HBox();
    hBox.getStyleClass().setAll("vu-meter");
    hBox.setSpacing(getSkinnable().getLedSpacing());
    vBox = new VBox();
    vBox.getStyleClass().setAll("vu-meter");
    vBox.setSpacing(getSkinnable().getLedSpacing());
    leds = FXCollections.observableArrayList();
    for (int i = 0; i < getSkinnable().getNoOfLeds(); i++) {
        Region led = new Region();
        led.setOnMouseClicked(new WeakEventHandler<>(event -> active = !active));
        led.setOnMouseEntered(new WeakEventHandler<>(event -> handleMouseEvent(event)));
        if (getSkinnable().getSections().isEmpty()) {
            led.getStyleClass().setAll("led");
        } else {
            for (Section section : getSkinnable().getSections()) {
                if (section.contains(i * stepSize.doubleValue())) {
                    led.getStyleClass().setAll("led", section.getStyleClass());
                }
            }
        }
        leds.add(led);
    }
    if (Orientation.HORIZONTAL == getSkinnable().getOrientation()) {
        vBox.setManaged(false);
        vBox.setVisible(false);
        hBox.getChildren().setAll(leds);
        peakLedIndex = 0;
    } else {
        hBox.setManaged(false);
        hBox.setVisible(false);
        FXCollections.reverse(leds);
        vBox.getChildren().setAll(leds);
        peakLedIndex = leds.size() - 1;
    }
    // Add all nodes
    getChildren().setAll(hBox, vBox);
}

Example 2 with WeakEventHandler

use of javafx.event.WeakEventHandler in project tilesfx by HanSolo.

the class SunburstChart method createSegment.

private Path createSegment(final double START_ANGLE, final double END_ANGLE, final double INNER_RADIUS, final double OUTER_RADIUS, final Color FILL, final Color STROKE, final TreeNode NODE) {
    double startAngleRad = Math.toRadians(START_ANGLE + 90);
    double endAngleRad = Math.toRadians(END_ANGLE + 90);
    boolean largeAngle = Math.abs(END_ANGLE - START_ANGLE) > 180.0;
    double x1 = centerX + INNER_RADIUS * Math.sin(startAngleRad);
    double y1 = centerY - INNER_RADIUS * Math.cos(startAngleRad);
    double x2 = centerX + OUTER_RADIUS * Math.sin(startAngleRad);
    double y2 = centerY - OUTER_RADIUS * Math.cos(startAngleRad);
    double x3 = centerX + OUTER_RADIUS * Math.sin(endAngleRad);
    double y3 = centerY - OUTER_RADIUS * Math.cos(endAngleRad);
    double x4 = centerX + INNER_RADIUS * Math.sin(endAngleRad);
    double y4 = centerY - INNER_RADIUS * Math.cos(endAngleRad);
    MoveTo moveTo1 = new MoveTo(x1, y1);
    LineTo lineTo2 = new LineTo(x2, y2);
    ArcTo arcTo3 = new ArcTo(OUTER_RADIUS, OUTER_RADIUS, 0, x3, y3, largeAngle, true);
    LineTo lineTo4 = new LineTo(x4, y4);
    ArcTo arcTo1 = new ArcTo(INNER_RADIUS, INNER_RADIUS, 0, x1, y1, largeAngle, false);
    Path path = new Path(moveTo1, lineTo2, arcTo3, lineTo4, arcTo1);
    path.setFill(FILL);
    path.setStroke(STROKE);
    String tooltipText = new StringBuilder(NODE.getData().getName()).append("\n").append(String.format(Locale.US, formatString, NODE.getData().getValue())).toString();
    Tooltip.install(path, new Tooltip(tooltipText));
    path.setOnMousePressed(new WeakEventHandler<>(e -> NODE.getTreeRoot().fireTreeNodeEvent(new TreeNodeEvent(NODE, EventType.NODE_SELECTED))));
    return path;
