Methods
 
Name Description
Internal protected (Protected Friend) method Cancelled(BackgroundWorker, DoWorkEventArgs) Checks if the user has requested cancellation of the background operation. (inherited from WorkUnit).
Internal protected (Protected Friend) method DoWork(BackgroundWorker, DoWorkEventArgs) Does the actual work allowing progress bar update and cancellation.
Public method DoWork() Executes the work synchronously.
Public method Equals(Object) Determines whether the specified object is equal to the current object. (inherited from Object).
Protected method FilterLinesToExport(HdlCurve[]) Filters the curves to export.
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (inherited from Object).
Protected method GetComputedLines(out HdlCurve[], out HdlCurve[], out HdlCurve[], out HdlCurve[], out HdlCurve[], out HdlCurve[], out HdlPicture[], out HdlText[]) Gets the computed curves for export.
Public method GetHashCode Serves as the default hash function. (inherited from Object).
Public method GetType Gets the Type of the current instance. (inherited from Object).
Protected method MemberwiseClone Creates a shallow copy of the current Object. (inherited from Object).
Protected method OrderAndPrintMetafile(Graphics, float, HdlCurve[], HdlCurve[], HdlCurve[], HdlCurve[], HdlCurve[], HdlCurve[], HdlText[], HdlPicture[])
Protected method PrintTriangles(Graphics, IList<SilhoWireAndTriangleData>)
Internal protected (Protected Friend) method ResetProgressParallel(int) Resets the progress bar for a parallel loop. (inherited from WorkUnit).
Public method ScaleLinesToWorld(float) Scales the computed lines to world coordinates and applies an extra scale factor.
Internal protected (Protected Friend) method StartContinuousAnimation(string, BackgroundWorker, params string[]) Start the animation for the continuous progress bar. (inherited from WorkUnit).
Internal protected (Protected Friend) method StopContinuousAnimation(BackgroundWorker) Stop the animation for the continuous progress bar. (inherited from WorkUnit).
Public method ToString Returns a string that represents the current object. (inherited from Object).
Internal protected (Protected Friend) method UpdateProgress(double, double, string, BackgroundWorker, bool, params string[]) Updates the progress bar value. (inherited from WorkUnit).
Internal protected (Protected Friend) method UpdateProgress(int, int, string, BackgroundWorker, bool, params string[]) Updates the progress bar value. (inherited from WorkUnit).
Internal protected (Protected Friend) method UpdateProgressAndCheckCancelled(int, int, string, BackgroundWorker, DoWorkEventArgs, bool, params string[]) Updates the progress bar value and checks if the worker thread has been canceled. (inherited from WorkUnit).
Internal protected (Protected Friend) method UpdateProgressAndCheckCancelledParallel(int, string, BackgroundWorker, DoWorkEventArgs, params string[]) Updates the progress bar value and checks if the worker thread has been canceled, for a parallel loop. (inherited from WorkUnit).
Internal protected (Protected Friend) method UpdateProgressParallel(double, string, BackgroundWorker, params string[]) Updates the progress bar value for a parallel loop. (inherited from WorkUnit).
Internal protected (Protected Friend) method UpdateProgressTo100(string, BackgroundWorker, params string[]) Set the progress bar to 100% and forces screen update. (inherited from WorkUnit).
Internal protected (Protected Friend) method WorkCancelled(Environment) Called when the work is cancelled. (inherited from WorkUnit).
Internal protected (Protected Friend) method WorkCompleted(Environment) Called when the work has completed. In the case you are modeling something, the environment parameter allows you to easily add the model to the entities collection. (inherited from WorkUnit).
Internal protected (Protected Friend) method WorkFailed(Environment) Called when the work has failed. (inherited from WorkUnit).
