class CEikBitmapButton : public CEikCommandButtonBase;

Description

This class provides member functions to enable you to create a command button with a bitmap image.

A bitmap button has no text associated with it: it displays a picture only.

Derivation

• MQikCommandHandler - Interface for classes responsible of executing commands
• MQikCommandListOwner - Interface for classes adding commands
• MEikBorderedControl - Interface for bordered controls

• CCoeControl - Control base class from which all other controls are derived
• CEikBorderedControl - A control which is drawn surrounded by a rectangular border
• CEikButtonBase - This is the base class from which concrete button controls (command buttons, option buttons and checkboxes) are derived
• CEikCommandButtonBase - Base class for command buttons
• CEikBitmapButton - This class provides member functions to enable you to create a command button with a bitmap image

IMPORT_C CEikBitmapButton();

Description

Default constructor.

IMPORT_C ~CEikBitmapButton();

Description

Destructor.

IMPORT_C void SetPictureL(const CFbsBitmap *aMain, const CFbsBitmap *aMask=0,TWhichComponent aWhich=EFirst);

Description

Sets the image to be displayed in the button, and an optional bitmap mask for the image.

Parameters

IMPORT_C void SetPictureFromFileL(const TDesC &aFilename, TInt aMain, TInt aMask=-1, TWhichComponent aWhich=EFirst);

Description

Set the buttons image to a bitmap stored in a file.

A bitmap mask may optionally be set using aMask . If the image cannot be read from the file, the button is not updated.

Parameters

IMPORT_C CEikImage *Picture(TWhichComponent aWhich=EFirst) const;

Description

Gets the image associated with the specified component.

Parameters

Return value

virtual IMPORT_C void ConstructFromResourceL(TResourceReader &aReader);

Description

Constructs a bitmap button from resource.

Parameters

protected: virtual IMPORT_C void WriteInternalStateL(RWriteStream &aWriteStream) const;

Description

Writes the internal state of the control and its components to aStream. Does nothing in release mode. Designed to be overidden and base called by subclasses.

Parameters
