Is the Model Workspace dirty?
显示 更早的评论
Is there a programatic way to determine if the model workspace is dirty, which is indicated by an asterisk next to "Model Workspace" in the model explorer?

Check this code out:
Z=get_param(gcs,'ModelWorkspace');
Z.isDirty

Does requesting that parameter make the workspace dirty? ;-)

To determine if the model is dirty:
This means a model has changes that are unsaved.
x = get_param( gcs, 'ModelWorkspace' )
x.isDirty
or
bdIsDirty( gcs )
or
isDirtyOff = strcmp( get_param( gcs, 'Dirty' ), 'off' )
or
isDirtyOn = strcmp( get_param( gcs, 'Dirty' ), 'on' )
To set the dirty bit:
This will trick Simulink to think there are changes that are unsaved.
examples:
- if you want to save a changed view when there has been no material changes to the model; or
- you opened or closed some tabs and want to save that change in state when there has been no other material changes to the model.
x = get_param( gcs, 'ModelWorkspace' )
x.isDirty = 1;
or
set_param( gcs, 'Dirty', 'on' )
To save the model:
save_system( gcs )
To close the model:
close_system( gcs )
To save and close the model:
close_system( gcs, 1 )
