ConstructFromResourceL(TResourceReader &)

IMPORT_C void

ConstructFromResourceL

(

TResourceReader &

aReader

)

[virtual]

Second phase construction from a resource.

This constructor initialises the list box model, flags, required dimensions etc. from a resource. The function fully constructs the associated list box model and item drawer for this list box.

Parameters

TResourceReader & aReader

A resource reader initialised to point at a list box resource

ConstructL(const CCoeControl *, TInt)

IMPORT_C void	ConstructL	(	const CCoeControl *	aParent,
			TInt	aFlags = 0
		)	[virtual]

By default Symbian 2nd phase constructor is private

This initializes the C-classes of a newly-created CEikTextListBox from supplied arguments. This function fully constructs the associated list box model and item drawer for this list box, and then invokes CEikListBox::ConstructL() .

Parameters

const CCoeControl * aParent	Parent control for this control.
TInt aFlags = 0	Flags for the list box.
