This avoids the filter text to take the focus.
In Android this prevents the launcher to start with the virtual keyboard
displayed.
In the future, the widget could also take keyboards event into account
like the ListWidget one.
This sendCommand() call interrupts the "this game is unsupported" call,
causing it to automatically cancel.
Fixes a bug introduced by 8cda1fe870e76efd7b13514ab304af64a8187377.
Also adds Cloud::Storage::SyncDownloadingInfo struct to pass around a bunch of numbers instead of having 3 methods for each number (in CloudManager, Storage and SavesSyncRequest).
A bit hacky (uses `friend`), but now while SaveLoadCloudSyncProgressDialog is modal, SaveLoadChooserDialog is still redrawing in the background, so the not-yet-ready saves buttons are being replaced with ready ones while the sync is in progress.
Removing GUI::CommandSender from SavesSyncRequest, so it doesn't update SaveLoadCloudSyncProgressDialog or SaveLoadChooserDialog from another thread.
Instead, these two are now polling CloudMan once per second themselves.
The previous commit was not sufficient as getIconsSet() returns a
reference to the SearchSet and it could then be used after the
mutex had been unlocked and while it was being modified in
initIconsSet() called in another thread.
The icons download dialog was triggering the grid launcher update after
icons had been downloaded. But that means no update was done if the
dialog had been closed during the download.
Now the GUIManager triggers the update. This fixes the missing update
when hiding the download dialog while downloading an icon set.
GuiManager::initIconsSet is called from a callback of the iconset
download dialog, which runs in a separate thread. That means the
iconset can be accessed from two separate thread (the GUI thread,
and the download thread).
This was not an issue until the previous commit as closing the
download dialog while a download was ongoing would crash ScummVM.
But now that the crash is fixed, a race condition was possible.
When using the mouse wheel (scroll up/down) in the Grid view, item tray for a selected game, ScummVM would exit
I didn't notice any side-effects from the fix, but someone more familiar with the code should confirm.
