HaXePunk GUI

1. Introduction

HaXePunk GUI is a toolset to display user interfaces that works with HaXePunk engine. It provide some basic components to allow the user to interact with the game. Try the demo

2. Key Features

  • Standards components : Button, ToggleButton, CheckBox, RadioButton, Label, TextArea, Panel, Window
  • Advanced components : Carousel, MenuList, MenuItem
  • Hierarchical composition of components with relative positionning
  • Event support (clicked, resized, hidden, shown, added_to_container, added_to_world, removed_from_container, removed_from_world, mouse_hover, mouse_out, etc. )
  • Customizable skins (by editing skin PNG file)

3. How to use

3.0. Installation

haxelib install HaxePunk-gui or get it from the the haxelib project page.

You will need to add some assets (currently 4 skins and 1 new font) to your haxepunk project. They are available in the package at haxelib project page as well, or directly here.

3.1. The ONE thing to remember

There is ONE thing to remember when using (or creating) HaXePunk GUI components :

ALWAYS use localX and localY attributes to place/move a component.

This is required to allow hierarchical imbrication of components since there are no accessors to x and y attributes that can be overriden. The component or its container will be displayed in the world at the right place automatically, do not try to write x and y attributes instead. If you need to know the component absolute position in the world, you can use the absoluteX and absoluteY read-only attributes, or read x and y without modifying them.

3.2. How it works

To use those components, you may want to understand how they work in HaXePunk Context.

  • Every component inherits com.haxepunk.gui.Control. com.haxepunk.gui.Control itself inherits com.haxepunk.Entity. To use a component, instantiate it and place it in your world.
  • Every Control can add child Controls. Child position become relative to his container's.
  • A child absolute position is updated by its container using its localX and localY attributes.
  • Components reacts automatically to user interaction by firing events (of type com.haxepunk.gui.event.ControlEvent). Events must be catch the flash way, i.e. : myComponent.addEventListener(Control.RESIZED, eventCatcherFunction);

3.3. Initialization

First, you may want to tweak some apects of the components. Here is an list of everything you can customize before starting using components :

// Choose custom skin. Parameter can be a String to resource or a bitmapData.
Control.useSkin("gfx/ui/defaultGuiSkin2.png");

// The default layer where every component will be displayed on.
// Most components use severals layers (at least 1 per component child).              |
// A child component layer will be <100.
Control.defaultLayer = 100;

// Padding between border and inner text. Set the default padding of every new Button 
// and ToggleButton. The padding attribute can be changed on instances after creation.
Button.defaultPadding = 4;

// Size in px of the tickBox for CheckBoxes. Default is skin native size : 12.
CheckBox.defaultBoxSize = 12;

// Same for RadioButtons.
RadioButton.defaultBoxSize = 12;

// Label defaults parameters affect every components that uses labels :
// Button, ToggleButton, CheckBox, RadioButton, MenuItem, Window Title.
// Those labels can still be edited any time using "myComponent.label" attribute.

// Label default font (must be a nme.text.Font object).
Label.defaultFont = nme.Assets.getFont("font/pf_ronda_seven.ttf");
// Label defaultColor. Tip inFlashDevelop : use ctrl + shift + k to pick a color.
Label.defaultColor = 0x1E4E82;
// Label default Size.
Label.defaultSize = 8;
