JavaFX (iii) window dragging

Problem Scenario:

In the previous article, we hid the window's default title bar, causing the mouse to click on the form to not be dragged.

Ideas:

Adds a mouse-down event Listener and Mouse drag event listener to the component.

Realize:

　　Code snippet:

Private double xoffset = 0;
Private double yoffset = 0;

Code snippet:

Root.setonmousepressed (MouseEvent event), {
Event.consume ();
Xoffset = Event.getscenex ();
Yoffset = Event.getsceney ();
});

Root.setonmousedragged (MouseEvent event), {
Event.consume ();
Stage.setx (Event.getscreenx ()-xoffset);

Make different judgments according to your own needs.
if (Event.getscreeny ()-yoffset < 0) {
Stage.sety (0);
} else {
Stage.sety (Event.getscreeny ()-yoffset);
}
});
