Detailed Description

PluginProcess subclasses are meant to notify about the progress state of some process (typically a plugin)

PluginProgress are mainly used alongside with tlp::Plugin instances to give user a visual feedback about the progress of the plugin. Every plugin in tulip got a pluginProgress member they can call to give progress feedbacks. When running, the plugin should make a call to tlp::PluginProgress::progress() indicating the current state of the compuation. The tlp::PluginProgress returns a tlp::ProgressState indicating what behavior the underlaying system should have (see tlp::ProgressState for details)

Member Function Documentation

virtual void tlp::PluginProgress::cancel ( )
pure virtual

Sets the state flag to cancel, notifying to the process that the user wants to cancel it. Canceling a process must stop it and revert all the changes performed since its start.

Returns
void
virtual std::string tlp::PluginProgress::getError ( )
pure virtual

Returns a message describing the error encountered during the process. If no error has been encountered, an empty string is returned.

Returns
:string A description of the encountered error, if any.
virtual bool tlp::PluginProgress::isPreviewMode ( ) const
pure virtual

The preview mode redraws the graph while applying the algorithm, making it slower.

Returns
bool Whether the preview mode is activated.
virtual ProgressState tlp::PluginProgress::progress ( int  step,
int  max_step 
)
virtual

Notifies the progression of the process.

Parameters
stepThe current step number.
max_stepThe total number of steps.
virtual void tlp::PluginProgress::setComment ( const std::string &  comment)
pure virtual

Changes the comment about the process progression.

Parameters
commentA description of what the plugin is currently doing, displayed to inform the user.
Returns
void
virtual void tlp::PluginProgress::setError ( const std::string &  error)
pure virtual

Sets the message describing the error encountered during the process.

Parameters
errorThe description of the encountered error.
Returns
void
virtual void tlp::PluginProgress::setPreviewMode ( bool  drawPreview)
pure virtual

The preview mode redraws the graph while applying the algorithm, making it slower.

Parameters
drawPreviewWhether the preview should be drawn.
Returns
void
virtual void tlp::PluginProgress::setTitle ( const std::string &  title)
pure virtual

Changes the title of that plugin progress.

Parameters
titlethe title to set
Returns
void
virtual void tlp::PluginProgress::showPreview ( bool  showPreview)
pure virtual

This tells the widget if it should show a preview checkbox, allowing the user to decide if the algorithm should draw a preview or not.

Parameters
showPreviewWhether the progress widget should contain a preview checkbox or not.
Returns
void
virtual ProgressState tlp::PluginProgress::state ( ) const
pure virtual

Gets the current internal state of the PluginProgress.

Returns
tlp::ProgressState The current state.
virtual void tlp::PluginProgress::stop ( )
pure virtual

Sets the state flag to stop, notifying to the process that the user wants to stop it. Stopping a process does not revert changes.

Returns
void
