## A class for processing and calculating minimum, current and maximum print time as well as managing the job name
|
|
#
|
|
# This class contains all the logic relating to calculation and slicing for the
|
|
# time/quality slider concept. It is a rather tricky combination of event handling
|
|
# and state management. The logic behind this is as follows:
|
|
#
|
|
# - A scene change or setting change event happens.
|
|
# We track what the source was of the change, either a scene change, a setting change, an active machine change or something else.
|
|
# - This triggers a new slice with the current settings - this is the "current settings pass".
|
|
# - When the slice is done, we update the current print time and material amount.
|
|
# - If the source of the slice was not a Setting change, we start the second slice pass, the "low quality settings pass". Otherwise we stop here.
|
|
# - When that is done, we update the minimum print time and start the final slice pass, the "high quality settings pass".
|
|
# - When the high quality pass is done, we update the maximum print time.
|
|
#
|
|
# This class also mangles the current machine name and the filename of the first loaded mesh into a job name.
|
|
# This job name is requested by the JobSpecs qml file.
