Constructs a new progress monitor for the given Gantt chart.

1.0
Method Detail

beginTask

public void beginTask(java.lang.String name,
                      int totalWork)
Description copied from interface: IProgressMonitor
Notifies that the main task is beginning. This must only be called once on a given progress monitor instance.

Specified by:
beginTask in interface IProgressMonitor
Parameters:
name - the name (or description) of the main task
totalWork - the total number of work units into which the main task is been subdivided. If the value is UNKNOWN the implementation is free to indicate progress in a way which doesn't require the total number of work units in advance.

done

public void done()
Description copied from interface: IProgressMonitor
Notifies that the work is done; that is, either the main task is completed or the user canceled it. This method may be called more than once (implementations should be prepared to handle this case).

Specified by:
done in interface IProgressMonitor

setCanceled

public void setCanceled(boolean value)
Description copied from interface: IProgressMonitor
Sets the cancel state to the given value.

Specified by:
setCanceled in interface IProgressMonitor
Parameters:
value - true indicates that cancelation has been requested (but not necessarily acknowledged); false clears this flag
See Also:
IProgressMonitor.isCanceled()

isCanceled

public boolean isCanceled()
Description copied from interface: IProgressMonitor
Returns whether cancelation of current operation has been requested. Long-running operations should poll to see if cancelation has been requested.

Specified by:
isCanceled in interface IProgressMonitor
Returns:
true if cancellation has been requested, and false otherwise
See Also:
IProgressMonitor.setCanceled(boolean)

setTaskName

public void setTaskName(java.lang.String name)
Description copied from interface: IProgressMonitor
Sets the task name to the given value. This method is used to restore the task label after a nested operation was executed. Normally there is no need for clients to call this method.

Specified by:
setTaskName in interface IProgressMonitor
Parameters:
name - the name (or description) of the main task
See Also:
IProgressMonitor.beginTask(java.lang.String, int)

subTask

public void subTask(java.lang.String name)
Description copied from interface: IProgressMonitor
Notifies that a subtask of the main task is beginning. Subtasks are optional; the main task might not have subtasks.

Specified by:
subTask in interface IProgressMonitor
Parameters:
name - the name (or description) of the subtask

worked

public void worked(int work)
Description copied from interface: IProgressMonitor
Notifies that a given number of work unit of the main task has been completed. Note that this amount represents an installment, as opposed to a cumulative amount of work done to date.

Specified by:
worked in interface IProgressMonitor
Parameters:
work - the number of work units just completed

internalWorked

public void internalWorked(double work)
Description copied from interface: IProgressMonitor
Internal method to handle scaling correctly. This method must not be called by a client. Clients should always use the method worked(int).

Specified by:
internalWorked in interface IProgressMonitor
Parameters:
work - the amount of work done
