virtual

Removes a matrix item from the current selection.

Removes a matrix item from the current selection.

Parameters

row	The row of the matrix item.
col	The column of the matrix item.

virtual void IlvMatrixSelection::delSelectionColumn ( IlUShort  col )

virtual

Removes a matrix column from the current selection.

Removes a matrix column from the current selection.

Parameters

col	The column of the matrix.

virtual void IlvMatrixSelection::delSelectionRow ( IlUShort  row )

virtual

IlvMatrixRowSelection* IlvMatrixSelection::getSelection

(

)

const

Returns the first group of selected matrix items.

Returns

IlvMatrixCoordinate** IlvMatrixSelection::getSelection

(

IlUShort &

count

)

const

Returns an array of selected matrix items.

The array contains the coordinates of the selected matrix items. Each coordinate pair corresponds to a matrix item. You are responsible for the deletion of this array. Use the cleanArraySelection method to delete this array.

Parameters

count

Contains the size of the array. If the selection is empty then the value is 0.

Returns

An array of selected matrix items. If the selection is empty then NULL is returned.

virtual void IlvMatrixSelection::itemDeleted ( IlUShort  row, IlUShort  col  )

virtual

Updates the current selection after a matrix item is deleted.

Call this method to update the current selection when a matrix item is deleted.

Parameters

row	The row of the matrix item.
col	The column of the matrix item.

virtual void IlvMatrixSelection::itemReplaced ( IlUShort  row, IlUShort  col  )

virtual

Replaces a matrix item.

Call this method to update the current selection when a matrix item is replaced by another.

Parameters

row	The row of the matrix item.
col	The column of the matrix item.

virtual void IlvMatrixSelection::rowDeleted ( IlUShort  row )

virtual

Updates the current selection after a matrix row is deleted.

Call this method to update the current selection when a matrix row is deleted.

Parameters

row	The row of the matrix item.

virtual void IlvMatrixSelection::rowInserted ( IlUShort  row, IlUShort  count = 1  )

virtual

Updates the current selection after matrix rows are inserted.

Call this method to update the current selection when matrix rows are inserted.

Parameters

row	The index of the first inserted row.
count	The inserted row count.

virtual void IlvMatrixSelection::startIgnoreNotification ( )

virtual

Stops updates to the selection.

After calling this method, all updates to the selection are ignored and lost until a call to the stopIgnoreNotification method is made. If this method is called twice, the stopIgnoreNotification method must also be called twice to cancel the effects of this method.

virtual void IlvMatrixSelection::stopIgnoreNotification ( )

virtual

Restarts updates to the selection.

After calling this method, all updates to the selection are processed again if the number of calls to this method matches the number of calls to the startIgnoreNotification method.
