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

◆ Perspective()

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

Constructs a perspective object.

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

Member Function Documentation

◆ category()

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

A string identifier for a plugin used for categorization purposes.

std::string the category of the plugin.

Implements tlp::Plugin.

Definition at line 146 of file Perspective.h.

◆ centerPanelsForGraph()

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

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

By default, this method does nothing.

◆ createPerspective

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

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

nameThe name of the PErspective to create.

◆ icon()

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

The icon (preferably a thumbnail) of the plugin.

std::string the icon path

Reimplemented from tlp::Plugin.

Definition at line 149 of file Perspective.h.

◆ instance()

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

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.

The perspective singleton

◆ isReservedPropertyName()

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.

true if the perspective is registered.

◆ mainWindow()

QMainWindow* tlp::Perspective::mainWindow ( ) const
The Perspective's main window.

◆ openProjectFile

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

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

paththe absolute path of the project file.

◆ progress()

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

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


◆ redirectStatusTipOfMenu()

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

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

◆ redrawPanels()

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

Tells the perspective that the graph visualizations should be redrawn.

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

◆ registerReservedProperty()

void tlp::Perspective::registerReservedProperty ( QString  )

Sets a new property name as registered.

◆ setInstance()

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

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

◆ showAboutPage

void tlp::Perspective::showAboutPage ( )

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

◆ showErrorMessage

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

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.

titleThe message's title.
sThe message to display.

◆ showFullScreen

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

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

fis true, switch to full screen mode. If false, switch to windowed mode

◆ showPluginsCenter

void tlp::Perspective::showPluginsCenter ( )

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

◆ showProjectsPage

void tlp::Perspective::showProjectsPage ( )

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

◆ showStatusMessage() [1/2]

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

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

◆ showStatusMessage() [2/2]

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

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

Definition at line 247 of file Perspective.h.

+ Here is the call graph for this function:

◆ showStatusTipOf

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

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

actiona QAction

◆ showTrayMessage

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

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

sThe message to display.

◆ start()

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.

progressA progress handler

◆ terminated

virtual bool tlp::Perspective::terminated ( )

Called when the user wants to close the application.

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 263 of file Perspective.h.

◆ typedInstance()

template<typename T >
static T* tlp::Perspective::typedInstance ( )
A typed instance of the perspective singleton.

Definition at line 174 of file Perspective.h.

Member Data Documentation

◆ _externalFile

QString tlp::Perspective::_externalFile

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.

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

Definition at line 128 of file Perspective.h.

◆ _mainWindow

QMainWindow* tlp::Perspective::_mainWindow

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 120 of file Perspective.h.

◆ _parameters

QVariantMap tlp::Perspective::_parameters

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 134 of file Perspective.h.

◆ _project

TulipProject* tlp::Perspective::_project

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.
