The idea is to allow backends to start a game even after the
LauncherDialog has been created, and for that they need a way
to close the existing GUI dialogs.
* 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
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 adapts the related graphics code, which is the generic Font API and the
TTF font implementation.
It furthermore adapts the GUI to properly take care of kerning in text input
widgets.
This fixes a problem where opening the keymapper dialog would cause the current game
keymap to be displayed as the active keymap but then changing the keymap selection
back to it would cause the GUI keymap to be displayed as the active one. The GUI keymap
was indeed at the top of the stack but that's not the desired effect.
Also move the pushing and popping of the keymap to Dialog::Open/Close
Also constantify the GUI keymap name
Formerly there was much special handling for the Tooltip dialog in
GuiManager::runLoop. This was replaced by overloading the event handling
functions in Tooltip. Also the Tooltip was adapted to be run like every
other normal dialog.
