I have a blank javafx.stage.Stage with no icons minimize, maximize, and close stage.initStyle(StageStyle.UNDECORATED);. I want to create them myself, because on the line with them will make more Buttons. Because I use an empty style for the Stage, I need to set a resizable borders for my window. There are standard ways to do this? Because to create them as a BorderPane and customize the dragging of the mouse is cumbersome.
I make resizable borders with mouse cursor position listener, it's work, I have not much time for optimized code:
public class Resize {
double eY = 0;
double eX = 0;
double eStrtY = 0;
double eStrtX = 0;
double sceneStrtY = 0;
double sceneStrtX = 0;
double minW = 600;
double minH = 600;
double w = 0;
public Resize(Stage stage, double w) {
Scene scene = stage.getScene();
AnchorPane root = (AnchorPane)scene.getRoot();
this.w = w;
root.setOnMousePressed(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent e) {
eStrtY = e.getSceneY();
eStrtX = e.getSceneX();
sceneStrtY = e.getSceneY();
sceneStrtX = e.getSceneX();
}
});
root.setOnMouseMoved(new EventHandler<MouseEvent>() {

// double w = 8;
