Functions related to the QObject class.

Function Documentation

dos_qobject_connect_static()

DOS_API void dos_qobject_connect_static	(	DosQObject *	sender,
		const char *	signal,
		DosQObject *	receiver,
		const char *	slot,
		DosQtConnectionType	connection_type
	)

Connect an object signal to another object signal or slot.

Note

Use the dos_signal_macro o dos_slot_macro for property format the string arguments

dos_qobject_create()

DOS_API DosQObject* dos_qobject_create	(	void *	dObjectPointer,
		DosQMetaObject *	metaObject,
		DObjectCallback	dObjectCallback
	)

Create a new QObject.

Parameters

dObjectPointer	The pointer of the QObject in the binded language
metaObject	The QMetaObject associated to the given QObject
dObjectCallback	The callback called from QML whenever a slot or property should be in read, write or invoked

Returns

A new QObject

Note

The returned QObject should be freed by calling dos_qobject_delete()

The dObjectPointer is usefull for forwarding a property read/slot to the correct object in the binded language in the callback

dos_qobject_delete()

DOS_API void dos_qobject_delete

(

DosQObject *

vptr

)

Free the memory allocated for the QObject.

Parameters

vptr	The QObject

dos_qobject_deleteLater()

DOS_API void dos_qobject_deleteLater

(

DosQObject *

vptr

)

Free the memory allocated for the QObject in the next event loop cycle.

Parameters

vptr	The QObject

dos_qobject_disconnect_static()

DOS_API void dos_qobject_disconnect_static	(	DosQObject *	sender,
		const char *	signal,
		DosQObject *	receiver,
		const char *	slot
	)

Disconnect an object slot or signal from an object signal.

Note

Use the dos_signal_macro o dos_slot_macro for property format the string arguments

dos_qobject_objectName()

DOS_API char* dos_qobject_objectName

(

const DosQObject *

vptr

)

Return the DosQObject objectName.

Parameters

vptr	The DosQObject pointer

Returns

A string in UTF8 format

Note

The returned string should be freed using the dos_chararray_delete() function

dos_qobject_property()

DOS_API DosQVariant* dos_qobject_property	(	DosQObject *	vptr,
		const char *	propertyName
	)

Read Value of a property by its name.

Parameters

vptr	The QObject
propertyName	the Name of the property to be read

Returns

Value of the given property

Note

returns an empty QVariant if the propertyName does not exist

dos_qobject_qmetaobject()

DOS_API DosQMetaObject* dos_qobject_qmetaobject

(

void

)

Return QMetaObject associated to the QObject class.

Returns

The QMetaObject of the QObject class

Note

The returned QObject should be freed using dos_qmetaobject_delete().

dos_qobject_setObjectName()

DOS_API void dos_qobject_setObjectName	(	DosQObject *	vptr,
		const char *	name
	)

Calls the QObject::setObjectName() function.

Parameters

vptr	The QObject
name	A pointer to an UTF-8 string

Note

The name string is owned by the caller thus it will not be deleted

dos_qobject_setProperty()

DOS_API bool dos_qobject_setProperty	(	DosQObject *	vptr,
		const char *	propertyName,
		DosQVariant *	value
	)

Write Value to a property by its name.

Parameters

vptr	The QObject
propertyName	The Name of the property to be written
value	The value to be written

Returns

Result as bool

dos_qobject_signal_emit()

DOS_API void dos_qobject_signal_emit	(	DosQObject *	vptr,
		const char *	name,
		int	parametersCount,
		void **	parameters
	)

Emit a signal definited in a QObject.

Parameters

vptr	The QObject
name	The signal name
parametersCount	The number of parameters in the parameters array
parameters	An array of DosQVariant with the values of signal arguments

dos_signal_macro()

DOS_API char* dos_signal_macro

(

const char *

str

)

Return the equivalent of SIGNAL(str) macro invokation.

Note

The returned string should be freed by calling the dos_chararray_delete() function

dos_slot_macro()

DOS_API char* dos_slot_macro

(

const char *

str

)

Return the equivalent of SLOT(str) macro invokation.

Note

The returned string should be free with dos_chararray_delete
