_gtkButtonImage

Set an image file into any button or get the current image object of a button.

Affecte un fichier image à un bouton ou récupère l'objet image en cours d'un bouton.

Type :

fun [ObjGtk P] [ObjGtk ObjGtk]

_button_ : ObjGtk : any button already created.

_file_ : P : read reference of the image filename. If _file_ is 'nil', the function returns its current image object. The image format can be all supported formats by GTK+. If the image is animated, the button will be animated.

Return : [ObjGtk ObjGtk] :

• The same button;
• The created image object (or the current image object if _file_ is nil).

If _button_ is nil, this tuple is nil

Example :

	typeof button = ObjGtk;;
	typeof image = ObjGtk;;
	fun main()=
		_showconsole;
		let _gtkButtonImage _gtkButtonNewLabel _channel "New file" _checkpack "tests/2dgtk/test.gif" -> [but img] in	// the button will be animated
		(
		set button = but;
		set image = img;
		...

Note : the image object can be reused to another context.
