java - Is it possible to use to use a path transition on a dialog box in javafx? -

so i'm running little test application see if possible , move main project. main idea dialog box come top of screen center , waits response the user. if click no, program terminates. if click yes, dialog box goes center top screen , out of sight user.

package test;  import java.util.optional; import javafx.animation.pathtransition; import javafx.application.application; import javafx.fxml.fxmlloader; import javafx.scene.scene; import javafx.scene.control.alert; import javafx.scene.control.alert.alerttype; import javafx.scene.control.buttontype; import javafx.scene.layout.vbox; import javafx.scene.shape.moveto; import javafx.scene.shape.path; import javafx.scene.shape.vlineto; import javafx.stage.stage; import javafx.util.duration;  public class test extends application {      @override     public void start(stage stage) throws exception     {         vbox root = fxmlloader.load(getclass().getresource("fxmldocument.fxml"));          alert alert = new alert(alerttype.confirmation);         alert.settitle("confirmation dialog");         alert.setheadertext("look, confirmation dialog");         alert.setcontenttext("are ok this?");          path path = new path();         path.getelements().add(new moveto(300, -25));         path.getelements().add(new vlineto(200));         pathtransition pathtransition = new pathtransition();         pathtransition.setduration(duration.millis(1500));         pathtransition.setpath(path);         pathtransition.setnode(alert); // problem lies.         pathtransition.setcyclecount(1);         pathtransition.play();          scene scene = new scene(root, 640, 480);          stage.setscene(scene);         stage.show();          optional<buttontype> result = alert.showandwait();          if (result.get() == buttontype.ok)         {             path path2 = new path();             path2.getelements().add(new moveto(300, 200));             path2.getelements().add(new vlineto(-25));             pathtransition pathtransition2 = new pathtransition();             pathtransition.setduration(duration.millis(1500));             pathtransition.setpath(path);             pathtransition.setnode(alert);             pathtransition.setcyclecount(1);             pathtransition.play();         }         else         {             stage.close();         }     }      public static void main(string[] args)     {         launch(args);     }  } 

there's way can move alert dialog, means of yproperty(). instead of path transition we'll use timeline set property. since read property, havet use doubleproperty within transition instead , use alert.sety().

the first part of question, sliding in dialog, easy. second, sliding out, more complex, since dialog closed inmediately once button clicked.

solution 1. sliding in

we need dialog dimensions , position, , need show it. means shown, , inmediately moved top of screen.

so i'll change alert.showandwait() alert.show().

@override public void start(stage primarystage) {      button btn = new button();     btn.settext("show sliding in alert dialog");     btn.setonaction(event -> {         alert alert = new alert(alerttype.confirmation);         alert.settitle("confirmation dialog");         alert.setheadertext("look, confirmation dialog");         alert.setcontenttext("are ok this?");          buttonbar buttonbar=(buttonbar)alert.getdialogpane().lookup(".button-bar");         buttonbar.setdisable(true);          alert.initmodality(modality.application_modal);         alert.show();         // can retrive alert bounds:         double yini=-alert.getheight();         double yend=alert.gety();         // , move alert top of screen         alert.sety(yini);          final doubleproperty yproperty = new simpledoubleproperty();         yproperty.addlistener((ob,n,n1)->alert.sety(n1.doublevalue()));          timeline timein = new timeline();         timein.getkeyframes().add(             new keyframe(duration.seconds(1.5),                  e->buttonbar.setdisable(false),                  new keyvalue(yproperty, yend,interpolator.ease_both)));         timein.play();          alert.resultproperty().addlistener((ob,r,r1)->{             if (r1 == buttontype.ok){                 // alert closed , hidden in final position             }             else{                 primarystage.close();             }         });      });      stackpane root = new stackpane();     root.getchildren().add(btn);      scene scene = new scene(root, 300, 250);      primarystage.settitle("hello world!");     primarystage.setscene(scene);     primarystage.show(); } 

the listener in yproperty() allow set position dialog within different positions interpolated during transition.

solution 2. slide in , out

this bit of dirty solution, since involves using second alert dialog, given original 1 closed once buttons clicked. we'll add second dialog behind first one, , use create slide out effect once first 1 closed.

the side effect notice fast blink in phase of showing second , putting first 1 on top of it.

@override public void start(stage primarystage) {     button btn = new button();     btn.settext("show sliding in alert dialog");     btn.setonaction(event -> {         alert alert = new alert(alerttype.confirmation);         alert.settitle("confirmation dialog");         alert.setheadertext("look, confirmation dialog");         alert.setcontenttext("are ok this?");          alert alertout = new alert(alerttype.confirmation);         alertout.settitle("confirmation dialog");         alertout.setheadertext("look, confirmation dialog");         alertout.setcontenttext("are ok this?");         alertout.initmodality(modality.none);         ((stage)alertout.getdialogpane().getscene().getwindow()).setopacity(0);          buttonbar buttonbar=(buttonbar)alert.getdialogpane().lookup(".button-bar");         buttonbar.setdisable(true);         alert.initmodality(modality.application_modal);         alert.show();                     // can retrive alert bounds:         double yini=-alert.getheight();         double yend=alert.gety();         // , move alert top of screen         alert.sety(yini);          final doubleproperty yproperty = new simpledoubleproperty();         yproperty.addlistener((ob,n,n1)->alert.sety(n1.doublevalue()));         timeline timein = new timeline();         timein.getkeyframes().add(             new keyframe(duration.seconds(1.5),                  e->{                    buttonbar.setdisable(false);                    // show second dialog                    alertout.show();                    // move front first 1                    ((stage)alert.getdialogpane().getscene().                         getwindow()).tofront();                 }, new keyvalue(yproperty, yend,interpolator.ease_both)));         timein.play();          alert.resultproperty().addlistener((ob,r,r1)->{             if (r1 == buttontype.ok){                 // show second dialog                 ((stage)alertout.getdialogpane().getscene().getwindow()).setopacity(1);                 buttonbar buttonbarout=(buttonbar)alertout.getdialogpane().lookup(".button-bar");                 buttonbarout.setdisable(true);                 final doubleproperty ypropertyout = new simpledoubleproperty(yend);                 ypropertyout.addlistener((ov,n,n1)->alertout.sety(n1.doublevalue()));                                                // create slide out transition                 timeline timeout = new timeline();                 timeout.getkeyframes().add(                     new keyframe(duration.seconds(1.5),                           e->alertout.close(),                          new keyvalue(ypropertyout, yini,interpolator.ease_both)));                 timeout.play();             }             else{                 alertout.close();                 primarystage.close();             }         });      });      stackpane root = new stackpane();     root.getchildren().add(btn);      scene scene = new scene(root, 300, 250);      primarystage.settitle("hello world!");     primarystage.setscene(scene);     primarystage.show(); }

solution 2. improved slide in , out

i've found way use 1 single dialog, , provide slide out effect too.

all takes trap click action on selected button, consume event, add slide out transition there, , hide dialog on finished.

@override public void start(stage primarystage) {     button btn = new button();     btn.settext("show sliding in alert dialog");     btn.setonaction(event -> {         alert alert = new alert(alerttype.confirmation);         alert.settitle("confirmation dialog");         alert.setheadertext("look, confirmation dialog");         alert.setcontenttext("are ok this?");          buttonbar buttonbar=(buttonbar)alert.getdialogpane().lookup(".button-bar");         buttonbar.setdisable(true);         alert.initmodality(modality.application_modal);         alert.show();                     // can retrive alert bounds:         double yini=-alert.getheight();         double yend=alert.gety();         // , move alert top of screen         alert.sety(yini);          buttonbar.getbuttons().stream().filter(b->((button)b).isdefaultbutton()).findfirst()             .ifpresent(b->((button)b).addeventfilter(eventtype.root,                  e->{                     if(e.geteventtype().equals(actionevent.action)){                         e.consume();                         final doubleproperty ypropertyout = new simpledoubleproperty(yend);                         ypropertyout.addlistener((ov,n,n1)->alert.sety(n1.doublevalue()));                                     timeline timeout = new timeline();                         timeout.getkeyframes().add(new keyframe(duration.seconds(1.5), t->alert.close(),                                 new keyvalue(ypropertyout, yini,interpolator.ease_both)));                         timeout.play();                     }                 }));          final doubleproperty yproperty = new simpledoubleproperty();         yproperty.addlistener((ob,n,n1)->alert.sety(n1.doublevalue()));         timeline timein = new timeline();         timein.getkeyframes().add(new keyframe(duration.seconds(1.5), e->{             buttonbar.setdisable(false);         },new keyvalue(yproperty, yend,interpolator.ease_both)));         timein.play();     });      stackpane root = new stackpane();     root.getchildren().add(btn);      scene scene = new scene(root, 300, 250);      primarystage.settitle("hello world!");     primarystage.setscene(scene);     primarystage.show(); }
