Detailed Description

QicsComboCellDisplay is a cell displayer for QicsTable that displays combo boxes in cells. This cell display class is different from QicsTextCellDisplay in that QicsComboCellDisplay inherits from both QicsMovableEntryWidgetCellDisplay and QComboBox. This means that the displayer object is also a combo box. This allows the programmer to easily use any QComboBox method or modify any QComboBox property.

virtual void QicsComboCellDisplay::displayCell	(	QicsGrid *	grid,
		int	row,
		int	col,
		const QicsDataItem *	itm,
		QRect &	rect,
		QPainter *	painter
	)			`[virtual]`

	)			`[virtual]`

Begin an edit operation in cell (row, col ). This method is intended to be used as a "preparation" for an edit operation. It will be called by the grid in response to a user action or a programmatic call. Note that this method does not specify a location in the grid widget for the edit operation to take place. The location will be specified in a subsequent call to moveEdit().

This method is called by the grid widget when the cell currently being edited has changed location in the grid. This would most commonly occur when the table is scrolled while an edit operation is underway.

Parameters:

	grid	the controlling grid
	row	the row in visual coordinates
	col	the column in visual coordinates
	rect	the new location of the cell

Reimplemented from QicsMovableEntryWidgetCellDisplay.

	row	the row in visual coordinates
	col	the column in visual coordinates
	me	the mouse event

Reimplemented from QicsCellDisplay.

		int	,
		int	,
		QKeyEvent *	ke
	)			`[virtual]`

This method is called by the grid widget when an edit operation of a cell should be ended. This would most commonly occur when the user traverses out of the cell via keyboard or mouse action.

Parameters:

	col	the column in visual coordinates

Reimplemented from QicsMovableEntryWidgetCellDisplay.

bool QicsComboCellDisplay::addValueToList ( void ) const

void QicsComboCellDisplay::setAddValueToList ( bool set )

Controls whether data values that are not in the combo box's list should be added to the list. If true, any value that this object attempts to display will be added to the combo box's list of choices, if it does not already appear in the list. If false, no values will be added to the list.

Implements QicsMovableEntryWidgetCellDisplay.

virtual void QicsComboCellDisplay::valueChanged	(	QicsGridInfo *	info,
		int	row,
		int	col,
		int	model_row,
		int	model_col,
		const QString &	val
	)			`[protected, virtual]`

This method is called when the value in the combobox for cell (row, col ) is changed. The new combobox value is val.

This method is intended to be reimplemented by subclasses of QicsComboCellDisplay. The programmer should implement this method so that it performs the appropriate action(s). Possible actions could include setting a new value in the QicsDataModel or performing some other action based on the state of the combobox.

If you use this method to set a new value in the data model, it is generally preferrable to use QicsGridInfo::setCurrentCellValue() or QicsGridInfo::setCellValue(), as these methods will ensure that the valueChanged signal of QicsTable is emitted.

Parameters:

	info	grid info object
	row	the visual row index of the cell whose value changed
	col	the visual column index of the cell whose value changed
	model_row	the model row index of the cell whose value changed
	model_col	the model column index of the cell whose value changed
	val	the new state of the checkbox
