otherwise. Reimplemented from IlvMatrix.
Reimplemented in IlvFileChooserSheet, and IlvHierarchicalSheet.
Handles resizing events applying to fixed columns.
Handles the specified event and calls the IlvMatrix::resizeRow()
member function.
event | The event to handle. |

, handleResizeRow()
. Reimplemented in IlvHierarchicalSheet.
Handles resizing events applying to fixed rows.
Handles the specified event and calls the IlvMatrix::resizeColumn()

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.
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.
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.
colno | The new first column. |
rowno | The new first row. |
Reimplemented from IlvAbstractMatrix.
