Implemented try/catch blocks for Slic3r exceptions and std::exceptions
with GUI error reporting. This is extremely important to report
corruption of PrusaSlicer.ini.
on application start-up, at least not on Windows.
wxEVT_CREATE was called for some control deep in the Plater, however
the event was delivered to the main frame and only for slicer, not
for G-code viewer. Thus the callbacks for 3D Mouse were not registered
for and the 3D mouse did not work on Windows.
Fixed by calling the callback registration from the first execution
of the Idle function.
Splash Screen under OSX requires a call of wxYeild() for update.
But wxYield() furthers a case, when CallAfter() in CLI::run() was called at the wrong time, before some of the GUI was created.
So, there is workaround:
Parameters needed for later loads are encapsulated to GUI_App::AFTER_INIT_LOADS structure
and are used in GUI_App::AFTER_INIT_LOADS::on_loads which is called just ones after wxEVT_IDLE
Fixed OSX specific bugs:
- toolbar flashing for some mainframe sizes (Retina specific)
- size of mainframe when settings layout in slNew mode
Added missed icons to the "white" folder
1. Fixed crash on OSX after change of the settings layout (PreferencesDialog should be destroyed before call of recreate_GUI)
2. Fixed dialog message during GUI recreation
3. In PreferencesDialog changed radio buttons view (under OSX they were bold)
4. slDlg mode - fixed switching between main frame and settings dialog (dialog->SetFocus() doesn't work under OSX, so we just hide it and show again)
check for other instances during startup
send message with command line arguments if found and terminate
listen for those messages and load objects from paths in messages from them
1) On Windows and Linux, the device enumeration now runs at a background
thread, while it ran on the UI thread on idle, which may have been
blocking on some rare Windows setups, see GH #3515#3733#3746#3766
2) On OSX, the device enumeration now relies on OS callback, no
polling is required.
3) Refactored for cleaner interface.
