Hi,
This doesn't quite make sense to me, the Left and Right have a resize
cursor, and neither of those are set as draggable. I guess it's because of
their height/placement. E.g., see left versus right (Label versus HBox) in
slightly tweaked code.
E.g.:
[image: curs.gif]
So this brings me to another problem. We don't want some nodes to be
draggable, such as the MenuBar. Because if it is, we end up with this:
[image: menu.gif]
And if you make it *non-draggable*, you lose the resize cursor (in
IntelliJ, you get both non-drag behaviour, and resize cursor above the
menu). It seems very confusing and non-intuitive; this relationship between
dragging options and seeing a resize cursor and how they're incompatible
re: the menu example.
public class MenuCursorIssue extends Application {
public static void main(String[] args) { launch(args); }
@Override
public void start(Stage primaryStage) {
MenuBar menuBar = new MenuBar();
final Menu file = new Menu("File");
file.getItems().addAll(new Menu("New"), new Menu("Open"));
menuBar.getMenus().addAll(file, new Menu("Edit"));
Region region = new Region();
HBox.setHgrow(region, Priority.ALWAYS);
// HeaderBar.setDragType(menuBar, HeaderDragType.DRAGGABLE_SUBTREE);
HeaderBar.setDragType(region, HeaderDragType.DRAGGABLE_SUBTREE);
HBox menuHbox = new HBox(menuBar, region);
final HeaderBar headerBar = new HeaderBar();
headerBar.setCenter(menuHbox);
primaryStage.initStyle(StageStyle.EXTENDED);
primaryStage.setScene(new Scene(new BorderPane(new Label("center"),
headerBar, null, null, null), 600, 400));
primaryStage.show();
}
}
Kind Regards,
Cormac
