Constructor & Destructor Documentation

gcu::Application::Application ( std::string  name,
std::string  datadir = DATADIR,
char const *  help_name = NULL,
char const *  icon_name = NULL 
)

Parameters:
name the name of the application.
datadir where data for the application are stored.
help_name the name to use for the help file (with .xml extension). If NULL, the name parameter is used.
icon_name the name to use for the default icon of all windows. If NULL, the help_name or name parameters will be used.
The datadir variable is used to build the full path to the help file: "file://"+datadir+"/gnome/help/"+name+"/"+LANG+"/"+name".xml".

virtual gcu::Application::~Application (  )  [virtual]

The destructor.

Reimplemented in gcp::Application.


Member Function Documentation

virtual Document* gcu::Application::CreateNewDocument (  )  [inline, virtual]

Virtual method used to create documents. Default behavior does nothing and returns NULL.

Returns:
the newly created document or NULL.

Parameters:
filename the uri of the file.
mime_type the mime type of the file if known.
bSave true if saving, and false if loading.

Returns:
the current screen resolution.

Definition at line 270 of file gcu/application.h.

std::map<std::string, GdkPixbufFormat*>& gcu::Application::GetSupportedPixbufFormats (  )  [inline]

Returns:
a std::map of the supported pixbuf formats. Keys are the mime type names.

Definition at line 181 of file gcu/application.h.

References m_SupportedPixbufFormats.

virtual GtkWindow* gcu::Application::GetWindow (  )  [inline, virtual]

Returns:
a GtkWindow if any. Should be overloaded by children classes.

Reimplemented in gcp::Application.

Definition at line 98 of file gcu/application.h.
