JavaFX UIControls• UIcontrolsinJavaFX canbelooselydefinedasfollows:

– AJavaFXNode• ItdoesnotnecessarilyextendfromControl• AUIcontrolcouldalsobecanvas-based,butIwon’tcoverthatindepthtoday

– TypicallystyledusingJavaFXCSS• Butnotrequired

– Typicallydesignedtobereusable• Butnotrequired


WhatisaNode?• EverythingintheJavaFXscenegraphisaNode.• UIcontrolsconsistofmanyNodes.– Lessisalwaysbetter– Butneedenoughtogetthedesiredstyling

ScrollBar RegionTrackRegionLeftButtonRegion RightButtonRegion

LeftArrowRegion ThumbRegion RightArrowRegion


RetainedModeRendering• Forthemostpart,JavaFXuses‘RetainedMode’rendering.• Thisbasicallymeans,wedon’tdrawdirectly,thescenegraph handlesthat.

• Thereisoneexception:theCanvasnodeallowsfor‘immediatemode’rendering.– CanvasisJava2D-like,butwedonotuseitforourJavaFXUIcontrolsatall.– Itremovesallofthepowerofthescenegraph (nolayouts,noCSS,noeventhandling,etc).

– Ithasitsuses….butformostUIcontrolsitisnotthebestoption.


WhyuseCSS?• “I’maJavadeveloper,nota*censored*CSSexpert!”• Ihearyou– beingaskedtouseCSScanbescaryattheoutset.• Trustme– itispowerfulandvery,veryniceonceyougetusedtoit.


Example:SceneBuilder



.root {-fx-base: rgb(50, 50, 50);-fx-background: rgb(50, 50, 50);-fx-control-inner-background: rgb(50, 50, 50);

}



.root {-fx-base: #7eaacc;-fx-background: #7eaacc;-fx-control-inner-background: white;

}


ChangesinJDK8


Controls-relatedchangesinJDK8• JDK8wasreleasedMarch2014,with:– SkinBase wasmadepublicAPI–MoreCSSAPIispublic– Right-to-Leftsupport– Newdefaultstyle(Modena)– Newcontrols(DatePicker,TreeTableView)– Lambdas!


Lambdas// option 1: the old, verbose style

rect.setOnMouseClicked(new EventHandler<MouseEvent>() {

@Override public void handle(MouseEvent event) {

handleMouseEvent(event);

}

});

// option 2: use bracketed lambdas

rect.setOnMouseClicked(event -> {

handleMouseEvent(event);

});

private void handleMouseEvent(MouseEvent event) {System.out.println(event);

}


Lambdas// option 3: get rid of brackets

rect.setOnMouseClicked(event -> handleMouseEvent(event));

// option 4: use method reference

rect.setOnMouseClicked(this::handleMouseEvent);

private void handleMouseEvent(MouseEvent event) {System.out.println(event);

}


Controls-relatedchangesinJDK8• JDK8u20wasreleasedAugust2014,with:– Ahuge numberofUIcontrolsbugfixes!– CSSAPIimprovements(lesscodingrequired)

• JDK8u40wasreleasedMarch2015,with:– NewUIcontrols(Spinner,FormattedTextField,Dialogs)– AccessibilityAPI(withsupportforallUIcontrols)

• JDK8u60wasreleasedAugust2015,with:– Ahuge numberofUIcontrolsbugfixes!– APIimprovementstoListView,TableView,etc

OptionsforBuildingCustomControls

Therearefourmainapproaches:1. CustomiseanexistingcontrolwithCSS2. Customiseanexistingcontrolbyreplacingtheskin3. Creatinganewcontrolbyextendingalayoutcontainer4. CreatinganewcontrolbyextendingfromtheControlclass


Option1:CustomiseAnExistingControlWithCSS


Option1:CustomiseAnExistingControlwithCSS• Momentofclarity!• JavaOneButton soundsremarkably liketheJavaFX Buttoncontrol• Unfortunately,itlooksnothinglikemyclientwantsittolooklike…

• CSStotherescue!

!=


Option1:CustomiseAnExistingControl

public class JavaOneButton extends Button {

public JavaOneButton(String text) {

super(text);

getStyleClass().add("javaone-button");

}

}

JavaCode:.javaone-button {

-fx-base: red;-fx-rotate: -5;-fx-scale-x: 2.5;-fx-scale-y: 2.5;

}

CSS:

modena.css/caspian.css



Button normalButton = new Button("Disappointing Normal Button");

JavaOneButton javaOneButton = new JavaOneButton("Hello JavaOne!");

scene.getStylesheets().add(JavaOneButton.class.getResource("javaone-button.css").toExternalForm());



Success!


Option1Discussion


1:WascreatingJavaOneButton necessary?• Itwasnot necessary• Wecouldhavejustdonethis:

– Problemwiththisapproach:• Lessreusable(everyonemustalwaysdothesecondline)• Morepronetorefactoringerrors• Moreverbose

Button javaOneButton = new Button("Hello JavaOne!");javaOneButton.getStyleClass().add("javaone-button");


2:Wascreatinga‘javaone-button’styleclassnecessary?• AllJavaFXUIcontrolshavedefaultstyleclassessetinthem– E.g.Buttonhas.button

• So,whydidn’twejustusethe.button styleclass?

.button {-fx-base: red;-fx-rotate: -5;-fx-scale-x: 2.5;-fx-scale-y: 2.5;

}

.javaone-button {-fx-base: red;-fx-rotate: -5;-fx-scale-x: 2.5;-fx-scale-y: 2.5;

}


2:Wascreatinga‘javaone-button’styleclassnecessary?

Itmightnotbewhatyouwant!


3:CanweremoverequirementtomanuallyimportCSSfile?• Itispossible toavoidrequiringuserstomanuallyimportthecss file.– Ratherthantheend-userdoingthis:

–WecouldhaveaddedthefollowingcodetoJavaOneButton:

• Endresult:CSSisencapsulatedinsidethecustomcontrol(whereitbelongs)


@Override public String getUserAgentStylesheet() {return JavaOneButton.class.getResource("javaone-button.css").toExternalForm();

}


3:CanweremoverequirementtomanuallyimportCSSfile?





Option1:InConclusion• IfaUIcontrolexistswiththeAPIyouwant,andtheskinisalreadyprettymuchwhatyouwant…option1shouldworkforyou!• Itispossibletoencapsulateallchangestothecontrolinanewsubclass,e.g.JavaOneButton• Developerdoesnotneedtodoanythingspecialtouseit

• I’llbebrieflytalkingaboutthisagaintomorrowat11am:‘WelcometotheNextLevel:Java9+Gluon+Mobile’


Option2:CustomiseAnExistingControlByReplacingTheSkin


Option2:Customisecontrolwithnewskin• SometimestherearejustnotenoughnodesintheexistingskinforCSStostyle.

ScrollBar RegionTrackRegionLeftButtonRegion RightButtonRegion

LeftArrowRegion ThumbRegion RightArrowRegion


Option2:Customisecontrolwithnewskin• SometimestherearejustnotenoughnodesintheexistingskinforCSStostyle.

• Creatingacustomskinallowsustotalfreedomtoputinthenodesthatweneed.

ScrollBar RegionLeftofThumbRegionLeftButtonRegion RightButtonRegion

LeftArrowRegion ThumbRegion RightArrowRegionRightofThumbRegion


Option2:Customisecontrolwithnewskin• Wewillcovercustomskinsmorewhenwegettooption4.

• Brieflythough,therearetwooptions:– Startinganewskinfromscratch(coveredlaterinoption4)– StartinginJDK9,allJavaFXUIcontrolskinsarepublicAPI• Thismeansthatyoucan,ifdesired,extendfromthem


Option2:Customisecontrolwithnewskin• Onceanewskiniscreated:– Createasubclassofthecontrol,–Overide createDefaultSkin,e.g.:

@Override protected Skin<?> createDefaultSkin() {

return new CustomButtonSkin(this);

}


Option3:ExtendALayoutContainer


Option3:ExtendALayoutContainer• OK– Optiononeandtwoseemsperfect,whywouldweeveruseadifferentapproach?

• Afewreasons:– TheUIcontrolAPIyouwantmightnotexist.Someonehastobuildthefirstone!–WhatifthebehaviourorvisualsoftheUIcontrolarenotasyouwant.• APIorfunctionalitymightbetooinflexible(ortooflexible)foryourliking

UsefulTips/Tools


CSSStyleable Properties• WecoveredCSSpseudoclassesinoptions3and4– Recallapseudoclassisthepartafterthecolon,e.g.‘hover’:

• Butwedidn’tcoverhowtocreatecustomstyleable properties– E.g.,‘javaone-year’:

.javaone-button:hover {-fx-color: -fx-hover-base;

}

.javaone-button {javaone-year: 2014;

}


CSSStyleable Propertiespublic class JavaOneButton extends Button {

private static final StyleablePropertyFactory<JavaOneButton> FACTORY = new StyleablePropertyFactory<>(Button.getClassCssMetaData());

private final StyleableProperty<Integer> javaoneYear =FACTORY.createStyleableIntegerProperty(this, "javaoneYear", "javaone-year", s -> s.javaoneYear);

// Typical JavaFX property implementationpublic final IntegerProperty javaoneYearProperty() { return (IntegerProperty)javaoneYear; }public final int getJavaoneYear() { return javaoneYear.getValue(); }public final void setJavaoneYear(int value) {javaoneYear.setValue(value); }

@Override public List<CssMetaData<? extends Styleable, ?>> getControlCssMetaData() {return FACTORY.getCssMetaData();

}

}


MultipleStyleClasses• InJavaFXyoucanhavemultiplestyleclassesonanode.• Forexample,youcouldadd‘javaone’toasingleButtoninstance,soyou’dhavetwostyleclasses:‘javaone’and‘button’.

• YoucanthenhaveCSSlikethis:.button {

-fx-color: gray;}.button.javaone {

-fx-color: red;}
