[Solved] nifty controls

hi guys,

i m very confused about nifty 1.3 … well about nifty at all

all i did until now was some static things… now i tried to make some dynamical tries… but i dont understand whats now important …

i tried a bit around nifty 1.2 (but never really understood) and now with nifty 1.3 i m totally confused.

how do u use the label for example?


<nifty xmlns=“http://nifty-gui.sourceforge.net/nifty.xsd” xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance” xsi:schemaLocation=“http://nifty-gui.sourceforge.net/nifty.xsd http://nifty-gui.sourceforge.net/nifty.xsd”>

<useStyles filename=“nifty-default-styles.xml” />

<useControls filename=“nifty-default-controls.xml” />

<controlDefinition name=“label” controller=“mygame.Controller”>

<text id=“text-id” font=“A.fnt” text=“old text” textHAlign=“center” textVAlign=“center” width=“100%” height=“100%” x=“0” y=“0” color="#f00f" />


<screen id=“start” controller=“mygame.Controller”>

<layer id=“layer” backgroundColor="#003f" childLayout=“center”>

<panel id=“panel” height=“25%” width=“35%” align=“center” valign=“center” backgroundColor="#f60f" childLayout=“center” visibleToMouse=“true”>

<interact onClick=“change()”/>


<onStartScreen name=“move” mode=“in” direction=“top” length=“300” startDelay=“0” inherit=“true”/>

<onEndScreen name=“move” mode=“out” direction=“bottom” length=“300” startDelay=“0” inherit=“true”/>

<onHover name=“pulsate” scaleFactor=“0.008” startColor="#f600" endColor="#ffff" post=“true”/>


<control name=“label” id =“label” align=“center”/>






like this should be the xml, nor?

the control “label” is there (btw should there only id? or only name? or both?)

and above a control definition for the “label”

now the java … well … i see that LabelControl is deleted for some reasons … but Label, LabelBuilder and CreateLabelControl are there, so i think i have to work with this… but could someone post an actually working example of the label for example, so i know how to use it in general?

i would really appreciate it!

my attemps so far :


Label l;

l = screen.findControl(“label”, ) [/java]

as 2nd argument i would need a controlClass… dunno what to do :frowning:

thx in advance


Label contols are used to be display texts

All controls works like that :


<control id ="ID" name="CONTROLNAME" [parametersForAllElement] [parametersSpecificToThisControl] />


parametersForAllElement :

Those parameters are use to define the size and the position of the element

You can use : width, height, align, valign, etc…

parametersSpecificToThisControl :

Those one depend from the control used.

For labels, you can use : text, font, textHAlign, textVAlign, …

For example, you can create a label like that :


<control id ="title" name="label" width="100%" height="50px" valign="top" text="My title" textHAlign="right" />


If you want to retrieve the label in the JAVA part, you have two choices :

Choice 1 :

You can retrieve the real controller of the element

Here is the definition of the control

[java] <controlDefinition style="nifty-label" name="label" controller="de.lessvoid.nifty.controls.label.LabelControl">[…][/java]

So you use something like this to retrieve it :


Element element = screen.findElementByName( "title" );

LabelControl control = element.getControl( LabelControl.class );

control.setText( "New title" );


Or the shortcut :


LabelControl control = screen.findControl( "title", LabelControl.class );

control.setText( "New title" );


This is the best method for custom control you create, but there is an easier method for classic Nifty controls.

Choice 2 :

Classic Nifty controls are implementing different services that enable you to interact with the control

Check this page to see which services are available for your control :


For the label control, you have only one service : Label

So you use something like that :


Label service = screen.findNiftyControl( "title", Label.class );


This one is cleaner.

The class Label is an interface implemented by the LabelControl that filter what can be use to manage the control. :slight_smile:


wow now its crystal clear! :slight_smile:

i already thought it might be just this simple, but that…well …

i got confused, that the 2nd argument has to be a ControllerClass… didnt thought Label itself woud do the job ^^

THX :slight_smile:

i still dont know what nifty is capable of, but this was A BIG help!



Excellent explanation didialchichi!

@terry: please forget Choice 1 and go with Choice 2 for the build-in Nifty controls! Choice 2 is the prefered way for this…
