java - javafx don't loss the focus when click other node -

i have vbox on left of rootpane,and vbox on right of rootpane. leftvobx have 3 textarea nodes,rightvbox have colorpicker; want: when choose 1 textarea node on leftvbox, click colorpicker on rightvbox, current textarea don't loss focus.

my idea same "scene builder" , when select note in workspace, handle right slide function area(like change color,set size , font),the note not lose focus, action know node in workspace need handle.

code: vbox leftbox = new vbox(); vbox rightbox = new vbox();

    leftbox.setprefsize(200, 250);     rightbox.setprefsize(200, 250);      leftbox.setstyle("-fx-background-color:blue");      button btn1 = new button("first");     button btn2 = new button("second");     button btn3 = new button("third");      colorpicker colorpicker = new colorpicker();      leftbox.getchildren().addall(btn1,btn2,btn3);     rightbox.getchildren().add(colorpicker);      colorpicker.setonaction(e->{             if(btn2.isfocused()){              btn2.settext("color changed.");         }     });      hbox root = new hbox();     root.getchildren().addall(leftbox,rightbox);      scene scene = new scene(root, 400, 250);      primarystage.settitle("hello world!");     primarystage.setscene(scene);     primarystage.show(); 

enter image description here

there no way have 2 nodes focused afaik. weird, since every keyboard event etc go 2 nodes. in javafx scene builder well, can try it. click on in scenebuilder , press delete, deleted. press on in scenebuilder , on right , press delete , item selected first not deleted. because doesn't have focus. scenebuilder shows had last selected.

to solve problem. make new variable button lastfocused; , make listeners on other buttons focusedproperty this:

btn2.focusedproperty().addlistener((observablevalue<? extends boolean> observable, boolean oldvalue, boolean newvalue) -> {     if(!newvalue) lastfocused = btn2; }); 

this should store button in new variable looses focus. looses focus when focus color picker, variable have button selected when color picker got selected.

now in color picker should work:

colorpicker.setonaction(e->{     lastfocused.settext("color changed.");     lastfocused.requestfocus(); }); 

i have not tested code.
