Detailed Description

Application object.

This class initializes GTK+ library and starts event loop. Normally user overrides this class using his own application object. Application objects are responsible to manage also terminating and clean-up procedures.

Constructor & Destructor Documentation

VDKApplication::VDKApplication	(	int *	argc,
		char **	argv,
		char *	rcf = (char*) NULL,
		bool	have_locale = false
	)

Constructor, receives main() arguments and pass them to GTK* library.

Parameters

rc	if isn't NULL <rc> resource file will be loaded and parsed.
have_locale	if true let's VDK to invoke gtk_set_locale() and support any languages that GTK supports.

VDKApplication::~VDKApplication ( )

virtual

Destructor

Member Function Documentation

bool VDKApplication::HasResources ( )

inline

Indicates if the resource file was loaded and parsed

GtkWidget * VDKApplication::MainWindow

(

)

Returns underlying gtk+ window of the application main form

void VDKApplication::RemoveGarbageCollection

(

)

Remove timed garbage collection.

void VDKApplication::Run

(

void

)

Initiates event loop

void VDKApplication::SetGarbageCollection

(

unsigned int

tick = 1000

)

Set a timed garbage collection that will be invoked each <timing> msecs.

void VDKApplication::SetIdleCallback	(	GtkFunction	idlecb = NULL,
		gpointer	data = (gpointer) NULL
	)

Sets idle callback function, if a previous idle callback was installed, uninstall it. /param /c idlecb idle callback function must be declared as: void idlecb(gpointer data); /param /c data will be passed to user defined function and must be a non NULL pointer otherwise SetIdleCallback won't work.

void VDKApplication::SetResourceFile

(

char *

rcf

)

Set a resource file. Tip: this should be done before Run()ning app.

virtual void VDKApplication::Setup ( )

pure virtual

Initializes Main form, user must override this one in his own application object.

void VDKApplication::Terminate

(

void

)

Terminates event loop and quits GTK* library. This method is called after a destroy event on MainForm, user normally doesn't care of it.

gint VDKApplication::VDKMessageBox	(	char *	caption,
		char *	text,
		int	mode = VDK_OK,
		char *	oktext = (char*) NULL,
		char *	canceltext = (char*) NULL,
		unsigned int	wait = 0
	)

Provide a modal dialog window for messages to user.
