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.

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

Member Function Documentation

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

inlineoverridevirtual

A string identifier for a plugin used for categorization purposes.

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

Implements tlp::Plugin.

Definition at line 146 of file Perspective.h.

◆ centerPanelsForGraph()

protectedvirtualslot

a virtual function to clear the last status message

◆ createPerspective

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.

◆ displayLogMessages

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

Member Data Documentation

◆ _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.

Note: 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

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, destroying the _mainWindow pointer could lead to undefined behavior.

Definition at line 120 of file Perspective.h.

◆ _parameters

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 134 of file Perspective.h.

◆ _project

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]

@list

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. @endlist
