java - How to specialize a components of JavaFX and hide its API to only show mine -


as said in title want specialize usage of tableview reuse many time, speciazation contains :

  • columns shown
  • filtering of added according default duplicate filter , addiotional (either based on boolean values or callbacks).

i use raw fxml files , controller, no ui drag , drop building.

in order keep usage of component easiest possible hide component part of javafx , allow methods, how ?

create class extending control. add methods want user access class.

create skin class , implement behavior don't want user access there.

benefits:

  • hides implementation details user.
  • allows user replace "private" behavior, if neccessary.
  • allows access "public" behavior form node directly.

example

control

public class mycontrol extends control {      @override     protected skin<?> createdefaultskin() {         return new mycontrolskin(this);     }      private final stringproperty text = new simplestringproperty();      public final string gettext() {         return this.text.get();     }      public final void settext(string value) {         this.text.set(value);     }      public final stringproperty textproperty() {         return this.text;     }  }

skin

public class mycontrolskin extends skinbase<mycontrol> {      public mycontrolskin(mycontrol control) {         super(control);          text text = new text();         text.textproperty().bind(control.textproperty());          getchildren().setall(text);     }  }

use

@override public void start(stage primarystage) {     final mycontrol control = new mycontrol();     button btn = new button("say 'hello world'");     btn.setonaction((actionevent event) -> {         control.settext("hello world!");     });      scene scene = new scene(new vbox(10, btn, control));      primarystage.setscene(scene);     primarystage.show(); }

note not matter how create ui. directly created java or loaded fxml - not matter. e.g. use skin fxml controller , root:

<fx:root type="javafx.scene.control.skinbase" xmlns:fx="http://javafx.com/fxml">     <children>         <text fx:id="text"/>     </children> </fx:root> 
@fxml private text text;  public mycontrolskin(mycontrol control) throws ioexception {     super(control);     getchildren().clear();      fxmlloader loader = new fxmlloader(someurl);     loader.setroot(this);     loader.setcontroller(this);     loader.load();      text.textproperty().bind(control.textproperty()); }

btw: duplicate filtering imho better of in seperate class, transformationlist. way reuse behavior independent of ui allow easier reuse (e.g. use listview).

i trying build cypher statement neo4j know 2-n starting nodes name , need find node (if any) can reached of starting nodes. at first tought similar "mutual friend" situation handled (start1)-[*..2]->(main)<-[*..2]-(start2) in case have more 2 starting points around 6 know name. so puzzled how can include third, fourth , on node cypher able find commmon root amongst them. in above example neo4j website need path starting 'dilshad', 'becky' , 'cesar' check if have common friend (anders) excluding 'filipa' , 'emil' not friends of three. so far create statement programmatically looks like match (start1 {name:'person1'}), (start2 {name:'person2'}), (start3 {name: 'person3'}), (main) (start1)-[*..2]->(main) , (start2)-[*..2]->(main) , (start3)-[*..2]->(main) return distinct main but wondering if there more elegant / efficient way in cypher possibly use list of names parameter ...

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.
