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.
But now there is a problem with font scaling.
Function font.Scaled(val) return scaled system font from primary monitor.
That is why application's name and version has so strange scale.
* Changed some labels on buttons. The Dialog name shows a purpose now
* SaveDialog is called, when UnsavedChangesDialog is shown.
* Added prototype for the "exit" icon
+ Fixed layout for the "Machine limits" page
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
+ Create controls only on the shown and active tab
+ Line class : deleted unused sizer
+ In GUI_Utils added TaskTimer class for the print a time of some task duration
+ BedShapeDialog:: activated options_groups
+ commented some unused code
UnsavedChangesDialog: Disabled "Move changes to selected preset" button, when printer technology is changed
PresetComboBox: Fixed color of the filament, if it is modified
1) All slicer's exceptions are now derived from Slic3r::Exception.
2) New exceptions are defined for slicing errors.
3) Exceptions are propagated to the Plater to show.
It remains to modify the slicing back-end to throw the new SlicingError
exceptions instead of std::runtime_error and to show the other exceptions
by a message dialog instead of a notification.
