Lengthen Javafx Sliders in GridPane - javafx

Question

Whatever I try, the slider refuses to lengthen/stretch horizontally. My theory is that the GridPane cell sizes are overriding the slider's x coordinate. Any solutions?
here's my entire class:
public class MoodMeter extends GridPane {
public MoodMeter() {
GridPane grid = new GridPane();
grid.setAlignment(Pos.TOP_CENTER);
grid.setHgap(10);
grid.setVgap(10);
grid.setPadding(new Insets(25, 25, 25, 25));
Slider slider = new Slider(-100, 100, 0);
slider.setOrientation(Orientation.HORIZONTAL);
slider.setMaxWidth(100);
slider.setBlockIncrement(100);
setHgrow(slider, Priority.ALWAYS);
grid.add(slider, 1, 0);
Scene scene = new Scene(grid, 700, 100);
Stage stage = new Stage();
stage.setTitle("Diary Mood Meter");
stage.setScene(scene);
stage.setResizable(false);
stage.show();
Rectangle2D desktop = Screen.getPrimary().getVisualBounds();
stage.setY(((desktop.getMaxY() + desktop.getMinY()) / 2) + 200);
}
}
And this is the result:
(not enough population)

Solved.
Changed
slider.setMaxWidth(100);
slider.setBlockIncrement(100);
to
slider.setMaxWidth(1000);
slider.setBlockIncrement(1000);

Answer 1

Without knowing the rest of your GridPane code setup, there are several ways to achieve that:
set slider.setMaxWidth(Double.MAX_VALUE)
add ColumnConstraints for horizontal resizing to the GridPane
set the Hgrow of your slider accordingly.

Answer 2

Just set the hgrow property for the slider to ALWAYS:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.control.Slider;
import javafx.scene.layout.GridPane;
import javafx.scene.layout.Priority;
import javafx.stage.Stage;
public class SliderInGridPane extends Application {
#Override
public void start(Stage primaryStage) {
GridPane root = new GridPane();
root.add(new Label("Value:"), 0, 0);
Slider slider = new Slider(0, 100, 50);
GridPane.setHgrow(slider, Priority.ALWAYS);
root.add(slider, 1, 0);
primaryStage.setScene(new Scene(root, 250, 75));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
