nbcol	The number of columns in the sheet.
nbrow	The number of rows in the sheet.
xgrid	The default column width.
ygrid	The default row height.
thickness	The thickness of the matrix.
showVSB	Specifies whether the vertical scroll bar should be shown (<`IlTrue`) or hidden (`IlFalse`).

virtual void IlvSheet::drawFrame	(	IlvPort *	dst,
		const IlvTransformer *	t = `0`,
		const IlvRegion *	clip = `0`
	)		const

virtual

Draws the gadget frame.

Is called from the draw() method. This method is not called if the method isShowingFrame() returns IlFalse.

Parameters

dst	The destination drawing port.
t	The transformer applied to the gadget.
clip	The clipping area.

See also: drawBackground(), drawScrollBar(), drawGadgetContents().

Reimplemented from IlvMatrix.

virtual void IlvSheet::drawGadgetContents	(	IlvPort *	dst,
		const IlvTransformer *	t = `0`,
		const IlvRegion *	clip = `0`
	)		const

virtual

Draws the gadget contents.

Is called from the draw() method. The default implementation does nothing.

Parameters

dst	The destination drawing port.
t	The transformer applied to the gadget.
clip	The clipping area.

See also: drawBackground(), drawScrollBar(), drawFrame().

Reimplemented from IlvMatrix.

virtual void IlvSheet::drawItem	(	IlvPort *	dst,
		IlUShort	colno,
		IlUShort	rowno,
		const IlvRect &	itembbox,
		const IlvRect &	clip
	)		const

virtual

Is called by the matrix to draw an item.

This method does nothing and should be redefined in subclasses to draw items.

Parameters

dst	The destination drawing port.
colno	The column of the item to be drawn. If the item extends over several columns, colno specifies the left location of the item.
rowno	The row of the item to be drawn. If the item extends over several rows, rowno specifies the top location of the item.
itembbox	The rectangle inside which the item should be drawn. If the item extends over several cells, itembbox is the bounding box of the cells contained by the item.
clip	The clipping area.

Reimplemented from IlvMatrix.

virtual IlBoolean IlvSheet::handleMatrixEvent ( IlvEvent & event )

virtual

Handles the events sent to the matrix.

Is called by the member function handleEvent() to handle an event applying to the matrix. Scroll bar events are handled by the method IlvScrolledGadget::handleScrollBarsEvent(). The default implementation does nothing and must be redefined if necessary.

Parameters

event The event.

Returns: IlTrue if the matrix used the event, or IlFalse otherwise.

See also: IlvGadget::handleEvent, IlvScrolledGadget::handleScrollBarsEvent.

Reimplemented from IlvMatrix.

Reimplemented in IlvFileChooserSheet, and IlvHierarchicalSheet.

virtual IlBoolean IlvSheet::handleResizeColumn ( IlvEvent & event )

virtual

Handles resizing events applying to fixed columns.

Handles the specified event and calls the IlvMatrix::resizeRow() member function.

Parameters

event The event to handle.

See also: IlvMatrix::resizeRow(), handleResizeRow().

Reimplemented in IlvHierarchicalSheet.

virtual IlBoolean IlvSheet::handleResizeRow ( IlvEvent & event )

virtual

Handles resizing events applying to fixed rows.

Handles the specified event and calls the IlvMatrix::resizeColumn() member function.

Parameters

event The event to handle.

See also: IlvMatrix::resizeColumn(), handleResizeColumn().

virtual void IlvSheet::itemBBox	(	IlUShort	col,
		IlUShort	row,
		IlvRect &	bbox,
		const IlvTransformer *	t = `0`
	)		const

virtual

Returns the bounding box of the item located in the specified cell.

Uses bbox to return the bounding box of the item located in the matrix cell specified by col and row, when the matrix is displayed with the transformer t.

Parameters

col	The index of of the column containing the item.
row	The index of the row containing the item.
bbox	The returned bounding box.
t	The transformer applied to the matrix.

Reimplemented from IlvMatrix.

virtual void IlvSheet::scrollTo	(	IlUShort	colno,
		IlUShort	rowno
	)

virtual

Changes the first visible column and row.

Scrolls the matrix so that the first visible column becomes colno and the first visible row rowno. Calling this method with a row or column that is fixed has no effect. The matrix is redrawn only if it is scrolled.

Parameters

colno	The new first column.
rowno	The new first row.

See also: scrollToRow(), scrollToColumn(), ensureVisible().

Reimplemented from IlvAbstractMatrix.
