Function not executing

Troubleshooting gui
1

I made a UI with nifty in Java. Currently I have the problem that my function is not executing when called (on click). My code:

[java]/*

                    //.. add more GUI elements here

    builder.registerPopup(nifty);
    Element popup = nifty.createPopup("choicepopup");
    Controller c = popup.getControl(Controller.class);
    if (c instanceof BadgePopupUI) {
        BadgePopupUI cui = (BadgePopupUI) c;
        cui.oep = oep;
    }
    nifty.showPopup(nifty.getCurrentScreen(), popup.getId(), null);
}

@Override
public void bind(Nifty nifty, Screen screen, Element elmnt, Properties prprts, Attributes atrbts) {
    this.nifty = nifty;
    this.screen = screen;
    this.popupElement = elmnt;
}

@Override
public void init(Properties parameter, Attributes controlDefinitionAttributes) {
}

@Override
public void onStartScreen() {
    System.out.println("Badge screen started");
}

@Override
public void onFocus(boolean getFocus) {
}

@Override
public boolean inputEvent(NiftyInputEvent inputEvent) {
    return true;
}

public void buttonClicked() {
    System.out.println("CLICKED ON THE X");
    //nifty.removeScreen("OptionScreen");
    nifty.closePopup(popupElement.getId());

}

}
[/java]

As you can see I put [java]interactOnClick(“buttonClicked()”);[/java] to see if it would make a difference, but it doensn’t. Anyone know why the function is not executing ?

2

try add visibleToMouse() in the builders and see if that does anything

3

Didn’t change anything. When I used an external class for my controller instead of the ui itself it works. Though I need it to work like this because I need the variable [java]oep [/java]in the function [java]buttonClicked()[/java]

4

Maybe this one helps

[java]
private BadgePopupUI me;

public BadgePopupUI(String name) {
    this._name = name;
    me = this
}

public void buildUI(Nifty nifty, BadgeEventPart part) {
    nifty.loadStyleFile(“nifty-default-styles.xml”);
    nifty.loadControlFile(“nifty-default-controls.xml”);
    oep = part;

    // <screen>

    PopupBuilder builder = new PopupBuilder(“choicepopup”) {
        {
            id(“choicepopup”);
            controller(me); // Screen properties

[/java]

or try

[java]
controller(BadgePopupUI.class);
[/java]

I’m not sure if it works, just play’n around a bit.

Thx, tried it but it doesn’t work.

Something different I tried:

My UI class:

      public void setBep(BadgeEventPart bep) {
      this.bep = bep;
      }
      }
      [/java]

In order to have the BadgeEventPart variable in my controller when the button is clicked i use a setter to set the variable.

Everything works fine, so the popup closes and the variable is set, though when I click the button the badgeventpart variable is null. Which is strange because is has been set with the setter.

Fixed it, just made the bep variable a public static variable.
