ConstructL(TBool)

void ConstructL ( TBool aShowEmptyCategories ) [private]

By default Symbian 2nd phase constructor is private.

Parameters

TBool aShowEmptyCategories

ExecuteLD(TLmkItemIdDbCombiInfo &)

IMPORT_C TInt ExecuteLD ( TLmkItemIdDbCombiInfo & aSelected )
This function launches the category selector dialog.Client use this function to launch single category selector dialog. This object is destroyed when this function returns or leaves.
leave
Leaves with system-wide leave codes.
panic
Panics with KLmkPanicNullMember, if the selector is not constructed properly.

Parameters

TLmkItemIdDbCombiInfo & aSelected

ExecuteLD(RArray< TLmkItemIdDbCombiInfo > &)

IMPORT_C TInt ExecuteLD ( RArray < TLmkItemIdDbCombiInfo > & aSelectedItems )

This function launches the category selector dialog.Client use this function to launch multiple category selector dialog. This object is destroyed when this function returns or leaves. If the array(aSelectedItems) is passed with already filled cateogry ids, then such categories will be shown as selected when the dialog is launched,but if any of these ids do not exist in landmarks database,will be ignored.

leave
Leaves with system-wide leave codes.
panic
Panics with KLmkPanicNullMember, if the selector is not constructed properly.

Parameters

RArray < TLmkItemIdDbCombiInfo > & aSelectedItems

NewL(TBool)

IMPORT_C CLmkCategorySelectorDlg * NewL ( TBool aShowEmptyCategories = EFalse ) [static]

This is a static function, which create and return an instance of this class. Categories present in the landmark database, are shown in selector.

leave
Leaves with KErrNotSupported if framework functionality is not available.
panic
Panics with system-wide panic codes.

Parameters

TBool aShowEmptyCategories = EFalse specifies whether categories without landmarks are shown or not

SetMopParent(MObjectProvider *)

IMPORT_C void SetMopParent ( MObjectProvider * aParent )

This function sets the context - that is, the enclosing parent control - for this control.

panic
Panics with KLmkPanicNullMember, if the selector is not constructed properly.

Parameters

MObjectProvider * aParent The parent object which is the context for the control.
