Detailed Description

An Ignition GUI application loads a QML engine and provides an API to load plugins and configuration files. The application supports either running a single main window or several plugins as standalone dialogs.

Constructor & Destructor Documentation

◆ Application()

Application	(	int &	_argc,
		char **	_argv,
		const WindowType	_type = `WindowType::kMainWindow`
	)

Constructor.

Parameters

[in]	_argc	Argument count.
[in]	_argv	Argument values.
[in]	_type	Window type, by default it's a main window.

◆ ~Application()

virtual ~Application ( )

virtual

Destructor.

Member Function Documentation

◆ AddPluginPath()

void AddPluginPath ( const std::string & _path )

Add an path to look for plugins.

Parameters

[in] _path Full path.

◆ DefaultConfigPath()

std::string DefaultConfigPath ( )

Get the location of the default configuration file.

Returns: The default configuration path.

See also: LoadDefaultConfig; SetDefaultConfigPath

◆ Engine()

QQmlApplicationEngine* Engine ( ) const

Get the QML engine.

Returns: Pointer to QML engine

◆ LoadConfig()

bool LoadConfig ( const std::string & _config )

Load a configuration file, which includes window configurations and plugins. This function doesn't instantiate the plugins, it just keeps them in memory and they can be applied later by either instantiating a window or several dialogs.

Parameters

[in] _config Full path to configuration file.

Returns: True if successful

See also: InitializeMainWindow; InitializeDialogs

◆ LoadDefaultConfig()

bool LoadDefaultConfig ( )

Load the configuration from the default config file.

Returns: True if successful

See also: SetDefaultConfigPath; DefaultConfigPath; LoadConfig

◆ LoadPlugin()

bool LoadPlugin	(	const std::string &	_filename,
		const tinyxml2::XMLElement *	_pluginElem = `nullptr`
	)

Load a plugin from a file name. The plugin file must be in the path. If a window has been initialized, the plugin is added to the window. Otherwise, the plugin is stored and can be later added to a window or dialog.

Parameters

[in]	_filename	Plugin filename.
[in]	_pluginElem	Element containing plugin configuration

Returns: True if successful

See also: LoadConfig; AddPluginsToWindow

◆ OnPluginClose

void OnPluginClose ( )

slot

Callback when user requests to close a plugin.

◆ PluginAdded

void PluginAdded ( const QString & _objectName )

signal

Notify that a plugin has been added.

Parameters

[in] _objectName Plugin's object name.

◆ PluginList()

std::vector<std::pair<std::string, std::vector<std::string> > > PluginList ( )

Get the list of available plugins, organized by path. The paths are given in the following order:

Paths given by the environment variable
Paths added by calling addPluginPath
Path ~/.ignition/gui/plugins
The path where Ignition GUI plugins are installed

Returns

A vector of pairs, where each pair contains:

A path
A vector of plugins in that path

◆ RemovePlugin()

bool RemovePlugin ( const std::string & _pluginName )

Remove plugin by name. The plugin is removed from the application and its shared library unloaded if this was its last instance.

Parameters

[in] _pluginName Plugn instance's unique name

Returns: True if successful

◆ SetDefaultConfigPath()

void SetDefaultConfigPath ( const std::string & _path )

Specifies the location of the default configuration file. This is the file that stores the user settings when pressing "Save configuration".

Parameters

[in] _path The default configuration full path including filename.

See also: LoadDefaultConfig; defaultConfigPath

◆ SetPluginPathEnv()

void SetPluginPathEnv ( const std::string & _env )

Set the environment variable which defines the paths to look for plugins.

Parameters

[in] _env Name of environment variable.
