|

60 | * The Main GUI class, comprises what people will see on the screen.<br>
|
---|
61 | * Note: Each Object (Item) is responsible for drawing itself on the screen.<br>
|
---|
62 | * Note2: The Frame is registered as a MouseListener and KeyListener, and
|
---|
63 | * processes any Events.
|
---|
64 | *
|
---|
65 | * TODO List:
|
---|
66 | *
|
---|
67 | * Back to standard:
|
---|
68 | * - JavaFX Text-hitting (requires JFX1.9)
|
---|
69 | * - Overlays and Vectors review
|
---|
70 | * - Pop-ups (unused in base Expeditee, only in Apollo)
|
---|
71 | * - Apollo input (test)
|
---|
72 | * - The rest of Apollo
|
---|
73 | * - Make sure clipping/invalidation takes twin-frames into account
|
---|
74 | * - Reinstate Simple input commands
|
---|
75 | * - Test LinkedTrack.paintInFreeSpace()
|
---|
76 | * - Test EmulatedTextItem.onMouseReleased(MouseEvent) (removed emulatedSource mouse button check)
|
---|
77 | * - Constrained placement of items
|
---|
78 | *
|
---|
79 | * Extra:
|
---|
80 | * - Self-describing input
|
---|
81 | * - Thread safety (most stuff on GIO event thread but Agents can start new threads)
|
---|
82 | * - Touch input
|
---|
83 | * - Better reflection??? (currently changes to the code break reflection as it relies on names)
|
---|
84 | * - JavaFX lag (always rendering to images doesn't gel well with JavaFX)
|
---|
85 | * - Swing widgets in JFX
|
---|
86 | * - JavaFX Widgets (exception on drawing?)
|
---|
87 | * - Reduce reliance on into-image rendering to improve JavaFX performance (utilise enforced-clip)
|
---|
88 | * - Block Swing ecosystem setup until window is available, or...
|
---|
89 | * - Reconfigure window-resized code so things are properly resized (PREFERRED).
|
---|
90 | * - Swing alpha-compositing of colours (currently alpha is ignored e.g. drop-shadow in transition).
|
---|
91 | * - Overly-thick extrusion lines (seems to depend on number of connected lines...)
|
---|
92 | * - Make FreeItems control pickup etc.
|
---|
93 | * - Remove MouseEventRouter
|
---|
94 | * - Highlighting (should be controlled by the items themselves)
|
---|
95 | * - Make Widgets into fully-fledged items (maybe???)
|
---|
96 | * - Merge Widget and HeavyDutyWidget
|
---|
97 | * - Redefine TextLayouts (relative/absolute layouts)
|
---|
98 | * - Settings exceptions (Password widget in JFX) (currently fixed with hack)
|
---|
99 | * - MessageBay (what did I mean by this specifically?)
|
---|
100 | * - Order-dependency of start-up code
|
---|
101 | * - MessageBay not refreshing at start-up
|
---|
102 | * - Invalidation hierarchy (item => frame => display controller area => window)
|
---|
103 | * - Add gesture data type checking
|
---|
104 | * - Paintable interface
|
---|
105 | * - EcosystemSpecific interface (utilise to enable/disable features based on ecosystem)
|
---|
106 | * - Remove/modify Mutable class (in Apollo.util, change to InOutReference)
|
---|
107 | * - Convert BlockingRunnable to interface
|
---|
108 | * - Modify Metronome to utilise Timeouts
|
---|
109 | * - Need AWT in FastAlphaEffect???
|
---|
110 | *
|
---|
111 | * General:
|
---|
112 | * - Tidy FrameGraphics
|
---|
113 | * - Comment
|
---|
114 | * - UserSettings.DEFAULT_PROFILE_NAME not actually a user setting
|
---|
115 | *
|
---|
116 | * Done:
|
---|
117 | * - Timers
|
---|
118 | * - Timer input animations
|
---|
119 | * - Finish DisplayController/FrameGraphics separation
|
---|
120 | * - Anchor constraints (create class)
|
---|
121 | * - Make MessageBay take lead from DisplayController
|
---|
122 | * - Make message bay display again (to do with above)
|
---|
123 | * - Tooltips (layout broken in Swing as window size not correct when tooltips laid out)
|
---|
124 | * - Frame transitions
|
---|
125 | * - Frame transitions in twin-frames mode drawing over each other
|
---|
126 | * - JFX DnD manager
|
---|
127 | * - Reinstate Simple
|
---|
128 | * - Reinstate exclude source
|
---|
129 | * - Reinstate commented code
|
---|
130 | * - Twin-frames division 0 at startup
|
---|
131 | * - Twin frames off-by-one frame size (draws a line of erroneous pixels)
|
---|
132 | * - MessageBay delays showing messages on start-up
|
---|
133 | * - JFX Antialiasing done on theScene??? Doesn't apply for our situation
|
---|
134 | * - Incorporate Clip class into code
|
---|
135 | * - Enforced clip
|
