Made GuiArrowButton a subclass of GuiAdvancedButton
Added consistency to ReplayHandler by renaming getMarkers() to getMarkerKeyframes() and removing redundant methods which can be accessed via KeyframeList class
CustomObjectRepository is now being saved to and loaded from the ReplayFile
The CustomObjectRenderer uses the GuiObjectManager's timeline cursor position as interpolation timestamp for the CustomImageObjects which are drawn if a GuiObjectManager is open (instant preview)
KeyframeList's add() method now removes Keyframes with the same timestamp before adding the new Keyframe
Transformations class now holds default values to prevent NullPointerExceptions in methods calling getTransformationForTimestamp()
Added Javadoc to Transformation POJO
Created NumberValueChangeListener which can be applied to GuiNumberInput objects
Made step size customizable in GuiDraggingNumberInput
Changing a ReplayImageAssets image now notifies the CustomImageObjects linked to that asset
Modified RoundUtils to provide a round() method which uses the DecimalFormat class instead of Math.round which is unstable
ComposedElement's entries are sorted so that GuiDropdown are always drawn on top
Modified thrown UnsupportedOperationExceptions in CustomImageObject to not be thrown if asset is null
Made GuiDropdown only accept instances of GuiEntryListEntry to avoid unneccessary toString() methods returning the name
Added GuiEntryListValueEntry which holds a Value and a Name to be displayed
Continued work on GuiObjectManager
Added HSV noise to GuiTimeline's textures to somewhat hide the repeating body texture
Implemented GuiTimeline in GuiObjectManager's GuiObjectKeyframeTimeline
Added asInt() method to TimestampValue, to avoid int casts of value field
Added enabled Field to DelegatingElement, which every instance can handle itself
Made isEnabled Field in GuiAdvancedTextField protected for subclasses to access
Made GuiDraggingNumberInput only draggable while enabled
Made GuiDropdown check enabled field before accepting mouse clicks
Properly tints GuiTexturedButton if disabled
Replaced Keyframe subclasses with Generic Types of Keyframe and replaced all instanceof calls
Replaced implementations of Linear and Spline interpolation to interpolate any Object that extends KeyframeValue and contains at least one public double Field. I'll need this for Keyframe interpolation in CustomImageObject Transformations
Made MarkerKeyframe *no* subclass of Keyframe to avoid conflicts with PositionKeyframe in instanceof checks for Keyframe#getValue
Created KeyframeList which extends ArrayList to provide some helping functions which DRY up the ReplayHandler
Split up ReplayHandler's keyframeList into timeKeyframeList and positionKeyframeList
Created GuiReplayManager to allow users to manage their assets.
Created BoundingUtils class to provide a simple method to fit an image into given bounds. This implementation fixes https://trello.com/c/WTnicWkJ/
