I wanna it will be okay when the number variables is changed, but when the are increased the button goes out from the window. How to fix it? Also how to put the bar down to the level of "10$", so they will be in the same row?
Before :
After :
Here is my code :
VBox vboxBottom = new VBox();
HBox hboxBottomElements = new HBox(15);
HBox hboxBottomMain = new HBox(0);
Region region = new Region();
region.setPrefWidth(500);
hboxBottomElements.getChildren().addAll(visaLabel, separator2, adLabel, separator3, governRelationStatus, separator4, region, next);
hboxBottomElements.setPadding(new Insets(5));
vboxBottom.getChildren().addAll(separator1, new Group(hboxBottomElements));
vboxBottom.setPadding(new Insets(3));
hboxBottomMain.getChildren().addAll(new Group(moneyBox), vboxBottom);
hboxBottomMain.setPadding(new Insets(3));
layout.setBottom(hboxBottomMain);
回答1:
By using a Group
here
vboxBottom.getChildren().addAll(separator1, new Group(hboxBottomElements));
you're creating a layout structure that resizes hboxBottomElements
to it's prefered size independent of the space available.HBox
simply moves elements out the right side of it's bounds, if the space available does not suffice. This means if the Group
containing moneyBox
grows, the Button
is moved out of the HBox
...
The following simpler example demonstrates the behavior:
@Override
public void start(Stage primaryStage) {
Button btn = new Button("Do something");
HBox.setHgrow(btn, Priority.NEVER);
btn.setMinWidth(Region.USE_PREF_SIZE);
Region filler = new Region();
filler.setPrefWidth(100);
HBox.setHgrow(filler, Priority.ALWAYS);
Rectangle rect = new Rectangle(200, 50);
HBox hBox = new HBox(rect, filler, btn);
Scene scene = new Scene(hBox);
primaryStage.setScene(scene);
primaryStage.show();
}
This will resize filler
to make the HBox
fit the window.
Now replace
Scene scene = new Scene(hBox);
with
Scene scene = new Scene(new Group(hBox));
and the Button
will be moved out of the window...
