Hi All,
I am using the Nifty Examples - MenuButtonControlDefinition. I am trying to add a menu button. However the Hover Effect and Button Clicked Event is not working. I am a Nifty-gui newbie. Could you please help me?
I am posting parts of the code…
[java]
public class MenuState extends BasicGameState {
@Override
public void init(GameContainer container, StateBasedGame sbGame)
throws SlickException {
this.container = container;
this.game = sbGame;
nifty = new Nifty(new LwjglRenderDevice(), new OpenALSoundDevice(),
new InputSystem() {
public void forwardEvents(
final NiftyInputConsumer inputEventConsumer) {
for (MouseEvent event : mouseEvents) {
event.processMouseEvents(inputEventConsumer);
}
mouseEvents.clear();
}
public void setMousePosition(int x, int y) {
}
}, new TimeProvider());
nifty.loadStyleFile("nifty-default-styles.xml");
nifty.loadControlFile("nifty-default-controls.xml");
nifty.registerMouseCursor("hand", "ca/concordia/conquest/core/gui/resources/sword.png", 5, 4);
nifty.registerSound("intro", "sound/19546__tobi123__Gong_mf2.wav");
nifty.registerMusic("credits", "sound/Loveshadow_-_Almost_Given_Up.ogg");
registerMenuButtonHintStyle(nifty);
registerStyles(nifty);
MenuButtonControlDefinition.register(nifty);
createIntroScreen(nifty);
createMainScreen(nifty);
nifty.gotoScreen("start");
}
private Screen createMainScreen(final Nifty nifty) {
nifty.setDebugOptionPanelColors(false);
mainScreen = new ScreenBuilder("main") {
{
controller(new ScreenControllerExample());
layer(new LayerBuilder("layer") {
{
backgroundImage("ca/concordia/conquest/core/gui/resources/logo.png");
childLayoutVertical();
panel(new PanelBuilder("navigation") {
{
childLayoutHorizontal();
width("100%");
height("100%");
panel(builders.hspacer("500px"));
panel(new PanelBuilder("buttonSet") {
{
childLayoutVertical();
width("300px");
height("500px");
panel(builders.vspacer("150px"));
control(MenuButtonControlDefinition.getControlBuilder("menuButtonPlayCampaign",
"Play Campaign",
"Play Campaign. Set of 10 Levels of Continuous Game Play.nNew Campaign Packages can be downloaded from our website."));
panel(builders.vspacer("15px"));
control(MenuButtonControlDefinition.getControlBuilder("menuButtonPlayArcade",

"Custom Maps created by Map Editor can be loaded using Arcade Game Mode."));
panel(builders.vspacer("15px"));

panel(builders.vspacer("15px"));
control(MenuButtonControlDefinition.getControlBuilder("menuButtonExit",
"Exit Game",
"Exit the game"));
}
});
}
});
}
});
}
}.build(nifty);
return mainScreen;
}
class ScreenControllerExample implements ScreenController, KeyInputHandler {
public void bind(Nifty nifty, Screen screen) {
}
public void onEndScreen() {
}
public void onStartScreen() {
}
@NiftyEventSubscriber(pattern = "menuButton.*")
public void onMenuButtonListBoxClick(final String id, final NiftyMousePrimaryClickedEvent clickedEvent) {

}

}
@Override

return false;
}
}
[/java]
I think it has to do with Alpha settings? The Hand Cursor is also not working 
What I have is,
https://docs.google.com/open?id=0BxDscS93ya4eNDdmZmZjNzEtMzU1NS00OTE5LWIyNDEtMjc1N2RlY2M2MGFl
What I want is the same effect as the Nifty GUI Example - MenuButtonControlDefinition with a ToolTip
https://docs.google.com/open?id=0BxDscS93ya4eZGIyOTg5MWEtYmZjMi00MTNlLTllYWEtNWFmNWNjYmEzN2Fj
I wonder why you’re instancing a new nifty object by hand, once you can create it easily with jme :
[java]
NiftyJmeDisplay niftyDisplay = new NiftyJmeDisplay(assetManager, inputManager, audioRenderer, viewPort);
Nifty nifty = niftyDisplay.getNifty();
[/java]
Also, for static controls and elements creation, the best way is using xml, and for dynamic controls / elements, the best way is using java.
Btw, I thought your code a little complicated for a nifty newbie.
The code you’ve included doesnt have any effects declared?
I would do the layout of your GUI in XML and interact with it using Java. Personally I think its bad practice to lay GUIs out using code because maintenance is so much more difficult.
Hi!
Thank you so much for your reply, both of you. I agree. But I do not have to choice. I dont have enough time to switch it all xml.
I found out the issue. It was the InputSystem problem. Now the problem is that Input Mouse Clicks are being suppressed.
Could someone good with Nifty Event Handling (EventBus?), please help me?

-.- It’s not jme at all!!!
Yes I understand. But could you please tell me how/why the InputSystem is not firing the NiftyEventSubscribers?
