C# Класс FSO.Client.UI.Framework.UIElement

Base class for all UIElements. This class has all the common stuff that user interface components have. This includes: X,Y, ScaleX, ScaleY, Visible, Parent etc. The UIElement has its own coordinate space. You can imagine that when you draw a texture inside a UIElement you are drawing it at 0,0 within the UIElement. This is then translated by the engine to screen coordinates.

Описание свойств

MASK_COLORS публичное статическое свойство

public static uint[] MASK_COLORS
Результат uint[]

Visible публичное свойство

Indicates if the component is visible or not. If false the UIElement should not draw. This must be implemented in the super class. UIElement does nothing with this variable.
public bool Visible
Результат bool

_BlendColor защищенное свойство

When the opacity changes this color will be changed into a representation of the opacity that can be used when calling the draw texture methods.
protected Color _BlendColor
Результат Color

_HasOpacity защищенное свойство

Boolean which indicates if the opacity is not 1.0. This is here as a utility because its faster to compare a boolean than to compare a float (_Opacity != 1.0f)
protected bool _HasOpacity
Результат bool

_Mtx защищенное свойство

Matrix object which represents the position & scale of this UIElement. Whenever X, Y, ScaleX, ScaleY, Parent (or any of these values on my parent) change We recalculate this matrix. It is used to convert local coordinates into absolute screen coordinates for drawing.
protected float[] _Mtx
Результат float[]

_MtxDirty защищенное свойство

Indicates if something has changed to make the Matrix invalid, e.g. X,Y has changed or the component is now inside a different parent object. Also called when the parent decides its dirty.
protected bool _MtxDirty
Результат bool

_Opacity защищенное свойство

Transparency value for this UIElement. Can be between 0.0 and 1.0
protected float _Opacity
Результат float

_OpacityDirty защищенное свойство

Indicates if the opacity has changed and we have not recauclated the blend colour
protected bool _OpacityDirty
Результат bool

_Parent защищенное свойство

The container which this element is a child of. Can be null if top level UI object. UIContainer sets this in its Add method. Helps describe the UI Tree.
protected UIContainer,FSO.Client.UI.Framework _Parent
Результат UIContainer

_Scale защищенное свойство

This is the absolute scale of this UIElement, Aka it is all the parent scales multiplied together finally multiplied by this UIElement's scale. Essentially, this is the scale value you would pass into a texture draw method. It is relative to the screen
protected Vector2 _Scale
Результат Vector2

_ScaleParent защищенное свойство

This is the absolute scale of this UIElement, Aka it is all the parent scales multiplied together. This is used for some specific calculations.
protected Vector2 _ScaleParent
Результат Vector2

_ScaleX защищенное свойство

Scale Factor of the X Axis.
protected float _ScaleX
Результат float

_ScaleY защищенное свойство

Scale Factor of the Y Axis.
protected float _ScaleY
Результат float

_Tooltip защищенное свойство

Tooltip of this UIComponent. This is displayed when the mouse is moved over the control.

Результат string

_X защищенное свойство

X position of this UIComponent. This coordinate is relative to this UIElement's parent component.
protected float _X
Результат float

_Y защищенное свойство

Y position of this UIComponent. This coordinate is relative to this UIElement's parent component.
protected float _Y
Результат float

ID of the element, this is not used by any functional code. It is only used in the debug UI Inspector to help you identify which component you are looking at.
protected string m_StringID
Результат string
