Detailed Description

Program progress reporter.

This class is used to output the percent completion for programs in either the command line mode or the graphical user interface. Generally, this object is created within a Process derived class. Therefore you should only use this object if you are developing such a class.

History:: 2003-05-16 Stuart Sides - Modified schema from astrogeology... isis.astrogeology...

History:: 2004-02-29 Jeff Anderson - Added ability to send progress status to the parent process

History:: 2005-02-11 Elizabeth Ribelin - Modified file to support Doxygen documentation

History:: 2005-10-03 Elizabeth Miller - Changed

History:: 2012-03-13 Steven Lambright - Added DisableAutomaticGuiRedraws().

History:: 2012-09-11 Steven Lambright - Added accessors to the current progress value and range. Renamed DisableAutomaticGuiRedraws() to DisableAutomaticDisplay() in order to include command-line progress printouts.

History:: 2012-10-04 Jeannie Backer - Removed documentation reference to the now non-existant CubeInfo class. No mantis ticket related to this change.

Constructor & Destructor Documentation

◆ Progress()

Isis::Progress::Progress ( )

Constructs a Progress object.

Exceptions

Isis::iException::User

Definition at line 22 of file Progress.cpp.

References Isis::PvlObject::findGroup().

◆ ~Progress()

Isis::Progress::~Progress ( )

Destroys the Progress object.

Definition at line 50 of file Progress.cpp.

Member Function Documentation

◆ AddSteps()

void Isis::Progress::AddSteps ( const int steps )

If the initial step size was a guess, it can be modified using this method.

For example, if you SetMaximumSteps(11) then call AddSteps(1) then the new MaximumSteps is 12. The progress bar will not go backwards (it will not drop from 10% to 5%). "steps" can be negative to remove steps.

Parameters

steps Amount to adjust the MaximumSteps by

Definition at line 199 of file Progress.cpp.

Referenced by Isis::ImageOverlapSet::FindAllOverlaps(), and Isis::OverlapStatistics::OverlapStatistics().

◆ CheckStatus()

void Isis::Progress::CheckStatus ( )

Checks and updates the status.

The first time this is invoked, it outputs the text from SetText and 0% processed. It should then be invoked for each step, for example, a step could be considered processing a line for NL lines in the image. If you do not call this enough times you will not reached 100% processed.

Exceptions

IException::Programmer Step exceeds maximumSteps

◆ CurrentStep()

int Isis::Progress::CurrentStep ( ) const

Returns the current step of the progress.

This value should always be in the range of: [0, MaximumSteps()]. CheckStatus() increments the current step.

See also: CheckStatus()

Returns: The current step of the progress

Definition at line 185 of file Progress.cpp.

Referenced by Isis::ImportControlNetWorkOrder::execute().

◆ DisableAutomaticDisplay()

void Isis::Progress::DisableAutomaticDisplay ( )

Turns off updating the Isis Gui when CheckStatus() is called.

You must use RedrawProgress() to visually update the current progress.

Definition at line 161 of file Progress.cpp.

Referenced by Isis::ImportControlNetWorkOrder::execute().

◆ MaximumSteps()

int Isis::Progress::MaximumSteps ( ) const

Returns the maximum number of steps of the progress.

See also: SetMaximumSteps()

Returns: The maximum number of steps of the progress.

Definition at line 172 of file Progress.cpp.

Referenced by Isis::ImportControlNetWorkOrder::execute().

◆ SetMaximumSteps()

void Isis::Progress::SetMaximumSteps ( const int steps )

This sets the maximum number of steps in the process.

Whenever this is invoked it also resets the counters to their initial states. This allows for programs which have multiple steps.

Parameters

steps Maximum number of steps

Exceptions

IException::Programmer Invalid value for step (must be >0)

◆ SetText()

void Isis::Progress::SetText ( const QString & text )

Changes the value of the text string reported just before 0% processed.

This text is only output under the following condition. After SetMaximumSteps is called, the first call to CheckStatus will immediately output the text. By default this is set to "Working".

Parameters

text	Text to output.

Definition at line 61 of file Progress.cpp.

◆ Text()

QString Isis::Progress::Text ( ) const

Returns the text to output.

Generally, this in not needed except rare circumstances where an application has multiple steps and the text string needs to be saved and restored.

Returns: string

Definition at line 72 of file Progress.cpp.

Member Data Documentation

◆ p_currentPercent

int Isis::Progress::p_currentPercent

private

The current percent we are checking against.

Once this percentage is exceeded we report that percentage is completed and increase this value by the increment.

Definition at line 80 of file Progress.h.

◆ p_currentStep

int Isis::Progress::p_currentStep

private

The current step in the processing sequence.

This is incremented by one everytime CheckStatus is called.

Definition at line 77 of file Progress.h.

◆ p_maximumSteps

int Isis::Progress::p_maximumSteps

private

Number of steps in your processing sequence.

For example, if there are 20 lines in an cube. This will be 20.

Definition at line 74 of file Progress.h.

◆ p_percentIncrement

int Isis::Progress::p_percentIncrement

private

How much to increment the currentPercent by.

It should only be 1,2, 5, or 10.

Definition at line 84 of file Progress.h.

◆ p_text

QString Isis::Progress::p_text

private

Text string to output at the initial call to CheckStatus (0% processed)

Definition at line 72 of file Progress.h.
