Detailed Description

The main application class handling startup as well as the main loop.

Definition at line 37 of file pencil2d.h.

Constructor & Destructor Documentation

Pencil2D::Pencil2D	(	int &	argc,
		char **	argv
	)

explicit

Initializes the application with the given command line arguments.

Parameters

argc	Number of arguments
argv	Values of the arguments

Definition at line 44 of file pencil2d.cpp.

Member Function Documentation

Status Pencil2D::handleCommandLineOptions ( )

Parses supplied command line arguments and performs the appropriate actions, such as running the command line exporter or preparing the GUI.

This method should be called before entering the main loop.

Returns

Status::OK if the arguments have been handled and the application is ready to enter the main loop
Status::SAFE if all necessary actions have been performed and the application is ready for shutdown
any other code if an error occurred and the application is unable to start.

See Also: exec()

Definition at line 72 of file pencil2d.cpp.

bool Pencil2D::isInstanceOpen ( )

Checks if multiple instances of Pencil2D are open.

If multiple instances of Pencil2D are open (indicated by a process holding the lock to a specific file in the application data directory) then the user will be warned of the issues with running multiple instances.

Returns: True if there are multiple instances running and the user has not chosen to ignore the warning, false otherwise.

Definition at line 109 of file pencil2d.cpp.

void Pencil2D::openFileRequested ( QString filename )

signal

Emitted when the operating system requests that a file should be opened.

Parameters

filename The file to be opened

See Also: QFileOpenEvent

void Pencil2D::prepareGuiStartup ( const QString & inputPath )

private

Readies the graphical UI for entering the main loop.

Parameters

inputPath Path of a file to be opened on startup.
