Class CGridCellImg

class CGridCellImg : public CBase;

Description

Draws a grid cell's contents.

Derivation

• CBase - Base class for all classes to be instantiated on the heap

• CGridCellImg - Draws a grid cell's contents

virtual IMPORT_C ~CGridCellImg();

Description

Destructor.

protected: IMPORT_C CGridCellImg();

Description

Default constructor.

inline TInt BurstColOffset() const;

Description

Gets the bursting column offset.

Return value

TInt The burst column offset

inline TInt BurstLeft() const;

Description

Gets the left hand bursting value.

Return value

TInt The burst value.

inline TInt BurstRight() const;

Description

Gets the right hand bursting value.

Return value

TInt The burst value

inline TBool IsHorizontalGridLines() const;

Description

Tests whether horizontal grid lines are drawn.

This function is set by the CGridImg object and allows classes derived from CGridCellImg to modify or restrict the area into which they draw.

Return value

TBool True, if horizontal grid lines are drawn; false, otherwise.

inline TBool IsVerticalGridLines() const;

Description

Tests whether vertical grid lines are drawn.

This function is set by the CGridImg object and allows classes derived from CGridCellImg to modify or restrict the area into which they draw.

Return value

TBool True, if vertical grid lines are drawn; false, otherwise.

inline void SetGridColors(const TGridColors &aGridColors);

Description

Sets the colours to be used when drawing.

Parameters

const TGridColors &aGridColors The object containing the grid colours specification.

private: virtual void DrawL(CGraphicsContext *aGc, const TCellRef &aCell, const TRect &aDrawRect, const TRect &aClipRect) const=0;

Description

Draws the contents of the specified cell.

Parameters

CGraphicsContext *aGc The graphics context to be used. const TCellRef &aCell The cell whose contents are to be drawn. const TRect &aDrawRect The rectangle in which the cell is to be drawn. const TRect &aClipRect The rectangle to which drawing is clipped.

private: virtual IMPORT_C TInt DataWidthInPixelsL(const TCellRef &aCell) const;

Description

Gets the width of the data contained in the specified cell.

Parameters

const TCellRef &aCell The cell to be tested.

Return value

TInt The width of the data, in pixels. The default implementation returns zero.

private: virtual IMPORT_C TBool DoesCellContainDataL(const TCellRef &aCell) const;

Description

Tests whether the specified cell contains data.

Parameters

const TCellRef &aCell The cell to be tested.

Return value

TBool True, if the cell contains data; false, otherwise. The default implementation returns true.

private: virtual IMPORT_C void Reserved_1();

Description

protected: TGridColors iGridColors;

Description

The grid colour specification.
