Detailed Description

A Perspective is a Tulip plugin that completely re-defines the user interface.

A Perspective aims at using the multiple features available in Tulip to create a complete, coherent workflow dedicated to a particular use-case. Perspectives are chosen by the user when first running the Tulip agent. The main perspective is called "Tulip". This perspective unveils all the Tulip features and aims at being a protyping and researching platform.

A Perspective always acts in its own process and communicate with the Tulip agent via TCP sockets. Thus, it is the Perspective's responsibility to offer the possibility to display graphs, run plugins, etc. A lot of helper classes can be found into the tulip-gui API like pre-made widgets, Qt models, etc.

Perspective's data is stored into a TulipProject. A TulipProject is an archive capable of containing heterogeneous data (like multiple graphs, textures, extra files, etc). When a TulipProject gets saved by a perspective, it is linked to it in its meta-information. Creating a Perspective primarily into implementing the start() method that builds the GUI. This method will be called by the overleying system when a new perspective is launched. The rest of the logic implementation is left to the developer.

Constructor & Destructor Documentation

tlp::Perspective::Perspective ( const tlp::PluginContext * c )

Constructs a perspective object.

Warning: There should not be any logic implemented into the Perspective's constructor. See the start method instead.

Member Function Documentation

virtual std::string tlp::Perspective::category ( ) const

inlinevirtual

A string identifier for a plugin used for categorization purposes.

Returns: std::string the category of the plugin.

Implements tlp::Plugin.

Definition at line 126 of file Perspective.h.

virtual void tlp::Perspective::centerPanelsForGraph ( tlp::Graph * )

virtual

Tells the perspective that the visualizations for a given graph should be centered.

Note: By default, this method does nothing.

void tlp::Perspective::createPerspective ( const QString & name )

protectedslot

Send a message to the Tulip agent to make him open a new Perspective without a project.

Parameters

name	The name of the PErspective to create.

std::string tlp::Perspective::icon ( ) const

inlinevirtual

The icon (preferably a thumbnail) of the plugin.

Returns: std::string the icon path

Reimplemented from tlp::Plugin.

Definition at line 129 of file Perspective.h.

static tlp::Perspective* tlp::Perspective::instance ( )

static

Since a Perspective has its own process to work in, there can be only one perspective instance by process. In order to ease the development process, Perspective are available as a singleton in order for child widgets and plugins to be able to access to the features of a Perspective. This architecture was added for developers who want to create an application containing several plugins grouped into Perspective.

Returns: The perspective singleton

bool tlp::Perspective::isReservedPropertyName ( QString name )

Checks if the name corresponds to a reserved properties. Perspectives are allowed to reserve graph properties. A reserved graph properties is a core property that cannot be deleted by the user and cannot be renamed.

Returns: true if the perspective is registered.

QMainWindow* tlp::Perspective::mainWindow ( ) const

Returns: The Perspective's main window.

virtual void tlp::Perspective::openProjectFile ( const QString & path )

protectedvirtualslot

Send a message to the Tulip agent to make him open a new Tulip Project.

Parameters

path	the absolute path of the project file.

virtual PluginProgress* tlp::Perspective::progress ( ProgressOptions options = ProgressOptions(IsPreviewable|IsStoppable|IsCancellable) )

virtual

Creates a progress handler and returns it. This method allows lower-level widgets to create top-level progress bars directly from the Perspective.

Returns

static void tlp::Perspective::redirectStatusTipOfMenu ( QMenu * menu )

static

a static function to enable the redirection of the statusTip or toolTip of menu actions on mainWindow->statusBar()

virtual void tlp::Perspective::redrawPanels ( bool center = false )

pure virtual

Tells the perspective that the graph visualizations should be redrawn.

Parameters

center if true, visualization should also be centered (eg. the layout has been changed)

void tlp::Perspective::registerReservedProperty ( QString )

Sets a new property name as registered.

static void tlp::Perspective::setInstance ( tlp::Perspective * )

static

Called at the beginning of the tulip_perspective to set the Perspective singleton.

See also: instance()

void tlp::Perspective::showAboutPage ( )

protectedslot

Send a message to the Tulip agent to make him display the "About us" page.

void tlp::Perspective::showErrorMessage	(	const QString &	title,
		const QString &	s
	)

protectedslot

Send a message to the Tulip agent to make him display an error message that will be shown in the system notification as well as on the welcome page.

Parameters

title	The message's title.
s	The message to display.

void tlp::Perspective::showFullScreen ( bool f )

protectedslot

Call this slot to swith to full screen or windowed mode.

Parameters

f	is true, switch to full screen mode. If false, switch to windowed mode

void tlp::Perspective::showPluginsCenter ( )

protectedslot

Send a message to the Tulip agent to make him display the Plugins Center page.

void tlp::Perspective::showProjectsPage ( )

protectedslot

Send a message to the Tulip agent to make him display the Projects page.

static void tlp::Perspective::showStatusMessage ( const QString & )

static

a static function to ease the display of messages on mainWindow()->statusBar()

static void tlp::Perspective::showStatusMessage ( const std::string & msg )

inlinestatic

a static function to ease the display of messages on mainWindow()->statusBar()

Definition at line 220 of file Perspective.h.

Here is the call graph for this function:

void tlp::Perspective::showStatusTipOf ( QAction * action )

protectedslot

Show the statusTip (or the toolTip) of an action on mainWindow()->statusBar()

Parameters

action a QAction

void tlp::Perspective::showTrayMessage ( const QString & s )

protectedslot

Send a message to the Tulip agent to make him display a message in the system notification area.

Parameters

s	The message to display.

virtual void tlp::Perspective::start ( tlp::PluginProgress * progress )

pure virtual

Build the main window GUI and starts the workflow. When this method is called, it means that the Perspective is reponsible of the application workflow until the application is closed by the user.

Parameters

progress A progress handler

virtual bool tlp::Perspective::terminated ( )

inlinevirtualslot

Called when the user wants to close the application.

Returns: Returning false prevents the window from being closed but the Perspective will have to implement its own way of closing the application.

Definition at line 234 of file Perspective.h.

template<typename T >

static T* tlp::Perspective::typedInstance ( )

inlinestatic

Returns: A typed instance of the perspective singleton.

Definition at line 151 of file Perspective.h.

Member Data Documentation

QString tlp::Perspective::_externalFile

protected

If the user provided a file to the tulip_perspective but this file is not recognized as a valid TulipProject, the full path of the file will be stored into the _externalFile member.

Note: Remember that perspectives should always store their data into TulipProject in order to keep a consistent workflow.

Definition at line 109 of file Perspective.h.

QMainWindow* tlp::Perspective::_mainWindow

protected

The main window on which the perspective should build the GUI.

It is not the Perspective's responsibility to destroy the main window when the application gets closed. Generally speaking, destorying the _mainWindow pointer could lead to undefined behavior.

Definition at line 103 of file Perspective.h.

QVariantMap tlp::Perspective::_parameters

protected

Contains extra parameters that have not been parsed by the overleying system. Those are considered to be Perspective-specific and are forwarded into this variable.

Definition at line 114 of file Perspective.h.

TulipProject* tlp::Perspective::_project

protected

The project associated to this perspective. This project can be empty or contain data depending on how the Perspective was launched: To launch a perspective, the tulip_perspective executable is called with the following arguments:

tulip_perspective [--perspective=Name] [file_path]

The –perspective argument forces Tulip to start the "Name" perspective. Even if the project states otherwise. If this argument is not specified, Tulip will look in the project's meta-data to dertermine the perspective to launch.
file_path is the absolute path of the project archive to associate with the perspective. If file_path is not given, the –perspective argument must be declared in order for Tulip to know what perspective to launch. In this case, _project will point to an empty (but valid!) project.
