when click button in scene 1, on-screen keyboard appear without closing scene!

on-screen keyboard has has own controller!

on-screen keyboard has textfield , complete keyboard

typed "stackoverflow" textfield of on-screen keyboard!

after pressing enter in on-screen keyboard how retrieve textfield value of on-screen keyboard customer name field of scene 1?

scene 1:

<textfield fx:id="customername" layoutx="14.0" layouty="75.0" onaction="#textboxtextchanged" prefheight="29.0" prefwidth="254.0"/> <button fx:id="onscreenkeyboardbutton" layoutx="268.0" layouty="75.0" mnemonicparsing="false" onaction="#buttonnameclick" prefheight="29.0" text="..." /> 

on-screen keyboard:

all key's and

enter button code:

<button fx:id="enterbutton" layoutx="796.0" layouty="210.0" minheight="18.8" mnemonicparsing="false" prefheight="40.0" prefwidth="90.0" text="enter" onaction="#buttonenterclick"/> 

scene 1 controller:

@fxml public void buttonnameclick(final actionevent event) {   //opens on-screen keyboard } 

on-screen keyboard controller:

@fxml public void buttonenterclick(final actionevent event) {   //code written text field of on-screen keyboard textfield of scene 1 } 

just create property in keyboard controller represent text, , observe "screen1controller":

public class keyboardcontroller {     private stringproperty text = new simplestringproperty(this, "text", "");     public stringproperty textproperty() {          return text ;     }     public string gettext() {         return text.get();     }     public void settext(string text) {         this.text.set(text);     }      @fxml     public void buttonenterclick(actionevent event) {         text.set(// text keyboard) ;     }     // ... else before } 

and

public class screen1controller {     @fxml     private textfield customername ;     // ...     @fxml     public void buttonnameclick(actionevent event) {         fxmlloader loader = new fxmlloader(getclass().getresource("keyboard.fxml"));         parent parent = loader.load();         keyboardcontroller controller = (keyboardcontoller) loader.getcontroller();         controller.textproperty().addlistener(new changelistener<string>() {             @override             public void changed(observablevalue<? extends string> obs, string oldvalue, string newvalue) {                 // update text field newvalue:                 customername.settext(newvalue);             }         });         // show keyboard ...     }      // other code... }
