* [Simulator] Create RadioKeyWidget class for UI buttons & refactor ButtonsWidget; Refactor SimulatedUIWidget (and subtypes) to use new RadioKeyWidgets/ButtonsWidget; Centralize help text for key mappings and get creative with some icons; Simplify some radio UI setups with rectangular buttons.
* [Simulator] Convert all simulator data I/O to signals/slots mechanism:
* SimulatorInterface/OpenTxSimulator:
- Now inherits from QObject to allow signal/slot interface;
- Allows data exchange on a per-item basis (eg. each I/O value is treated separately instead of sending whole arrays or structs of data);
- Checks for data changes and only emits signals when change is detected (GUI can now assume only new values are being sent);
- Manages its own 10ms timer (doesn't rely on GUI to do that);
- Sends "heartbeat" signals @ 1Hz for status monitoring;
* Simulator GUI:
- All data is exchanged between GUI elements as well as SimulatorInterface via signals/slots using standardized methods;
- Data is sent immediately, and only, when actually changed (eg. a control is moved) instead of in bulk at specific time intervals;
- Similarly, an asynchronous method is used for reading incoming data, w/out timers or loops;
- Improve VirtualJoystickWidget to be more encapsulated and configurable;
- Pause telemetry simulator if window is hidden;
* [Simulator] Move SimulatorInterface instance to separate thread, ensure safe asynchronous operations & proper timer interactions; Protect/remove some functions, & reorganize the order (cosmetics).
* [Simulator] Traces are now delivered to OpenTxSimulator and one or more QIODevice(s) can be added as recipient(s); Add SimulatorInterface::getCapability() for compile-time settings; Remove reversed POT1/SLIDER1 mixer exception (Taranis) requirement for SIMU; Fix plus/minus key delay on wheel event w/out encoder.
* [Simulator] Add current knob/slider/trim input value in tool-tips (KnobWidget and SliderWidget).
* [Simulator] Fix trims widget internal value not properly updating, and remove trim influence on virtual joystick X/Y value display (closes#4671).
* [SimulatorInterface] Add handling of transmitter input voltage, including a rough conversion of volts to ADC value for different boards, and default battery volts lookup function; Clear analogs array before starting.
* [Simulator] Add SimulatorInterface::init() method to separate pre-startup tasks; Report actual trim range, not just extended on/off; Change how radio widget states are restored; VirtualJoystickWidget: Connect trim changes directly from simulator, connect joystick events directly, report stick mode directly instead of setting values/constraints externally.
* [Simulator] Calculate default Tx V input based on configured range in radio settings (or warning V+2 for radios which don't support a range).
* [Simulator] Add functional aux. trims for Horus (closes#4699).
* [Companion] Remove problematic QMessageLogContext from AppDebugMessageHandler::messageOutput().
* [Simulator] Prevent trim change via slider if disabled for flight mode (closes#4600).
* [OpenTxSimulator] Fixes for Qt < 5.4.
* [OpenTxSimulator] Fix slot name.
* [package] Add QtSvg support DLLs for Windows.
* [Simulator] Add images/css resources for new version; Create SimulatorIcon and SimulatorStyle classes; Build with SVG support, remove unused bitmaps.
* [Simulator] Improve and simplify VirtualJoystickWidget resize event (sticks maintain X/Y position) & improve values layout w/out trims.
* [Simulator] Refactor Trainer simulator to use VirtualJoystickWidget, gains lock/hold buttons and X/Y position readout.
* [Simulator] More compact layout for Telemetry simulator, reduces min. width and adds scrolling columns to allow smaller window sizes.
* [Simulator] Add new SimulatorMainWindow and RadioOutputsWidget UI classes.
* [storage] Add non-persistent sessionId() to AppData for tracking currently active radio profile ID.
* [Simulator] Major UI updates:
* Use a MainWindow interface with dockable/floatable windows, proper toolbar & menu;
* Persistent size/layout state of all windows/docks/etc between uses, per radio profile;
* Completely separate radio Outputs window with configurable layout (also persistent between uses);
* Translations now enabled in standalone Simulator, follows main Companion setting (they need a lot of updates);
* New custom icons throughout, toolbar icon sizes adhere to user preference in Companion.
* [Simulator] Debug Output console updates:
* New filter feature with optional full RegEx support, can work in inclusive or exclusive modes (full help text is included in UI);
* Up to 50 user-defined filters are saved to permanent settings, also a few predefined filters are provided;
* Saves/restores the last filter used and if it was en/disabled;
* Added word wrap and clear screen features;
* Configurable scroll-back buffer size;
* Increased efficiency & performance of the buffering/printing process.
* [Simulator][OSX] Visual UI tweaks for OS X.
* [Simulator] Fix some debug console settings not being restored properly.
* [Simulator] Add ability to hide/show menu bar; Persist view state of menu bar and radio title bar; Reduce font size on OS X; Other small visual tweaks and improvements.
* [build] Add QtSvg to Linux build scripts (a guess for Dockerfile).
* [build] Fix for Qt 5.3.
* Add OpenTx headers to new files.
* [Companion][storage] Update GeneralSettings() initializer to use current sessionId for profile data retrieval, removes workaround for standalone Simulator being started with arbitrary profile; AppData: always update sessionId when global id() changes.
* [X10] Fixes for new simulator
