IMPORT_C void SetContentTypePropertiesL(const TQikListBoxPropertiesBase &aProperties, const RArray< TInt > &aSlotsToSwap);
Set properties for the content type of this row/column. The parameter passed must be of the correct type for the content type this element contains. Parameter aSlotsToSwap must always be supplied but is only used when setting properties upon a arrow content type, hence it can be an empty array when setting other properties, but do not forget to close it.
void Class::FooL() { const TQikListBoxContentsType type = iMyListBoxColumn->ContentType(); RArray<TInt> slotsToSwap; slotsToSwap.AppendL(ESlot1); slotsToSwap.AppendL(ESlot2);
makes sure to build properties of the correct type switch(type) { case EQikListBoxIcon: { TQikListBoxPropertiesIcon props; props.iSizeType = EQikListBoxMedium; iMyListBoxColumn->SetContentTypePropertiesL(props, slotsToSwap); break; } case EQikListBoxText: { TQikListBoxPropertiesText props; props.iMinLines = 1; props.iMaxLines = 1; iMyListBoxColumn->SetContentTypePropertiesL(props, slotsToSwap); break; } case EQikListBoxLeftArrow: { TQikListBoxPropertiesArrowLeft props; iMyListBoxColumn->SetContentTypePropertiesL(props, slotsToSwap); break; } case EQikListBoxRigthArrow: { TQikListBoxPropertiesArrowRight props; iMyListBoxColumn->SetContentTypePropertiesL(props, slotsToSwap); break; } default: break; }

IMPORT_C void SetContentTypeL(const TQikListBoxPropertiesBase &aProperties, const RArray< TInt > &aSlotsToSwap);
Constructs a new component based upon the properties supplied adding it to this element and replacing any previous component. Passing a TQikListBoxPropertiesParent will delete the component making the element a parent capable of having child elements.
|
|
IMPORT_C TQikListBoxContentsType ContentType() const;
Gets the type of component this element has. Based upon the type of component the correct SetProperties function can be called to set properties.
|
IMPORT_C void GetContentTypeProperties(TQikListBoxPropertiesIcon &aProperties) const;
Gets the properties of the icon content type of this element. Always make sure to get the properties using the correct GetContentTypeProperties function for the content type this element contains.
void Class::Foo() const { const TQikListBoxContentsType type = iMyListBoxColumn->ContentType(); switch(type) { case EQikListBoxIcon: { TQikListBoxPropertiesIcon props; iMyListBoxColumn->GetContentTypeProperties(props); break; } case EQikListBoxImage: { TQikListBoxPropertiesThumbnail props; iMyListBoxColumn->GetContentTypeProperties(props); break; } default: break; } }
|
|
IMPORT_C void GetContentTypeProperties(TQikListBoxPropertiesThumbnail &aProperties) const;
Gets the properties of the thumbnail content type of this element. Always make sure to get the properties using the correct GetContentTypeProperties function for the content type this element contains.
|
|
IMPORT_C void GetContentTypeProperties(TQikListBoxPropertiesText &aProperties) const;
Gets the properties of the text content type of this element. Always make sure to get the properties using the correct GetContentTypeProperties function for the content type this element contains.
|
|
IMPORT_C void GetContentTypePropertiesL(RArray< TInt > &aSlotsToSwap) const;
Sets the properties of the arrow content type of this element. Always make sure to get the properties using the correct GetContentTypePropertiesL function for the content type this element contains.

protected: CQikListBoxComponentBase * iComponent;
Pointer to this layout elements component.
protected: TSize iComponentSize;
When a component has calculated its size it is temporarily cached here.
protected: TMargins8 iDrawingMargins;
The margins that will actually be used when laying out the element. This may differ from the margins property of the element since vertical margins are overriden in row aware mode.
protected: TQikListBoxLayoutValuesFrontEnd & iLayoutValues;
Reference to the object keeping the centralized settings for layout needs.
