* Delete multiple empty rows
* Make getVolume non-virtual and leave just the implementation
in base class
* Resolve warning about signed / unsigned comparison in
gui-manager
* Clear availableVoices when updating voices on linux
* By default set language to transMan language on windows
(if the transMan is available)
* Remove freeVoices method from Windows ttsMan, it isn't needed
anymore
- Add comment to tts initialization on Windows
- Correctly free the voicesInfo in linux ttsMan
- Remove popState method from linux-text-to-speech.h and
windows-text-to-speech.h
- Add tts to help in configure
- Refactor language setting in gui-manager.cpp
It counted with english being the default language in
ttsMan constructors, which isn't true anymore.
The ScummVM was crashing because of an assert, when there was less
voices availaible, than what was set in the ConfMan.
Now the voice just falls back to 0th voice, if there are not
enough voices.
Unfortunatedly the encoding used by ScummVM breaks the
speech-dispatcher, so after trying to say non-ascii character
the connection has to be restarted. So for now I am restricting
the GUI TTS to english only.
Drawing nows happens directly when the Dialog or Widget draw methods are
called. This makes it easy to debug why a particular low level draw
method was called, by inspecting the call stack.
This replaces the notion of "buffering" by two independant ways to
control what is drawn and where:
- The active layer is used to select whether the foreground or
background part of the dialogs are rendered by the draw calls.
- The active surface is used to select if the draw calls affect the back
buffer or the screen.
The foreground layer of the active dialog is drawn directly to the
screen. Its background layer is drawn to the back buffer. This way
widgets can restore the back buffer in order to update without having to
redraw the dialog's background.
Dialogs lower in the dialog stack are drawn entirely to the back buffer.
The previous combination of a fixed 10 milliseconds delay and time since
last update checks meant that in most cases 20 milliseconds elapsed
between two calls to updateScreen resulting in a 50 fps framerate. On
systems with wait for vsync enabled that meant that some frames were
missed.
The new frame limiter waits for a variable delay equal to the non
consumed time in the slot allocated to the frame.
This fixes tons of warnings with clang from a recent xcode version on
macOS (and possibly other systems) complaining that an instantiation
of _singleton is required but no definition is available.
This is achieved by adding a list of GuiObject to delete to GuiManager
and doing the deletion in GuiManager::runLoop.
The main purpose of this is to avoid the deletion of ButtonWidget object
while their ButtonWidget::sendCommand function is being called. For
example the sendCommand of the Apply button of the OptionsDialog
may cause a rebuild (if the GUI language was changed) which tries to
delete the widgets inside the OptionsDialog, including the Apply button.
Previously, they only reacted to the mouse position once it was moved.
This meant that if the cursor was on a button that just gained focus,
it did not highlight.
Fixes#7101.
This patch fix bug #6841
If this runloop catches both the repeated key down event and the key up event.
In this case they key down will close the tooltip, because it got closed the key up event will be ignored.
As a result the LauncherDialog will never get notified the SHIFT state might have changed and not adapt the button description.
In this patch we just pass event to topDialog, if activeDialog was closed.
Also we must check, If topDialog doesn't exist.
