Member Enumeration Documentation

enum QdbtSelection::change_t [inherited]

Chause for a change of the table's geometry Enumeration values: SINGLE_ROW_INSERT  As single row has been inserted SINGLE_ROW_DELETE  As single row has been removed SINGLE_COL_INSERT  As single column has been inserted SINGLE_COL_DELETE  As single column has been removed DIMENSION_SET  The table's geometry has been set explicitly

---

Constructor & Destructor Documentation

QdbtSingleRowSelection::QdbtSingleRowSelection (  QdbtBaseTabular *    ctx )

Construct a row selection object for the tabular context. This selection object does only support one row being selected at a time. Warning: Please do not forget to inform this selection on the size of the tabular after creating it (if the tabular already has a size different from 0x0)

QdbtSingleRowSelection::~QdbtSingleRowSelection (    )  [virtual]

Destroy the selection object

---

Member Function Documentation

bool QdbtSingleRowSelection::cellSelectable (  int    row, int    col )  [virtual]

Query of the cell at position row, col is selectable. Implements QdbtSelection.

bool QdbtSingleRowSelection::cellSelected (  int    row, int    col )  [virtual]

The tabular components use this member function to query, if the cell at row, col is selected or not. Implements QdbtSelection.

QdbtBaseTabular * QdbtSelection::context (    )  const [protected, inherited]

Retrieves the context() (pointer the tabular widget instance) for this selection

void QdbtSingleRowSelection::dump (    )  [protected, virtual]

Prints the current status of the selection object to STDERR Reimplemented from QdbtSelection.

void QdbtSingleRowSelection::keyEvent (  QKeyEvent &    e, int    row, int    col )  [virtual]

Notifies the selection class on a key event happened at row, col. The description of the event is passed as \e. Reimplemented from QdbtSelection.

void QdbtSingleRowSelection::mouseEvent (  QMouseEvent &    e, int    row, int    col )  [virtual]

Notifies the selection class on a mouse event happened at row, col. The description of the event is passed as \e. Reimplemented from QdbtSelection.

void QdbtSelection::repaintCell (  int    row, int    col )  [protected, inherited]

This member ensures that the cell at row, col is being repainted. A customized QdbtSelection-class may use this member function, if a cell has changed its selection state.

bool QdbtSingleRowSelection::rowSelectable (  int    row )  const [protected]

Query, if a row row is selectable or not.

int QdbtSingleRowSelection::rowSelected (    )  const [protected]

Returns the row currently being selection (or -1 if no row is selected at all)

bool QdbtSingleRowSelection::rowSelection (  int    row )  const [protected]

Query the selection state of the row row

void QdbtSingleRowSelection::setCellSelectable (  int    row, int    col, bool    sel )  [virtual]

Set if the cell at position row, col is selectable or not to sel. Implements QdbtSelection.

void QdbtSingleRowSelection::setCellSelected (  int    row, int    col, bool    sel )  [virtual]

Set the selection state of the cell at position row, col to sel. Implements QdbtSelection.

void QdbtSingleRowSelection::setRowSelectable (  int    row, bool    selection )  [protected]

Sets whether a row row is selectable ( selection = TRUE ) or not.

void QdbtSingleRowSelection::setRowSelection (  int    row, bool    selection, bool    force )  [protected]

Set the selection state of row to selection. If force is set to TRUE, some checks are additionally left out, hoping that the caller know what he/she is doing.

void QdbtSingleRowSelection::setRowSelection (  int    row, bool    selection )  [protected]

Set the selection state of row to selection.

void QdbtSelection::setSelection (  bool    state )  [virtual, inherited]

Set the table's complete selection (if possible) to state. The base implementation does this by setting the selection state of each individual cell to the state given.

void QdbtSelection::signalCellSelected (  int   , int   , bool    )  [signal, inherited]

This signal may be used to have the table component, which is managing this selection object, emit the signal QdbtBaseTabular::cellSelected(int,int,bool) This signal is used to inform other components of the programm, that a selection state of the table has changed.

void QdbtSelection::signalRowSelected (  int   , bool    )  [signal, inherited]

This signal may be used to have the table component, which is managing this selection object, emit the signal QdbtBaseTabular::selected(int,bool) This signal is used to inform other components of the programm, that a selection state of the table has changed.

void QdbtSelection::tableChanged (  change_t    op, int    row, int    col )  [virtual, inherited]

This function is being called whenever the table's geometry is being changed. The reason op as well as affected row and/or col is being passed.

void QdbtSingleRowSelection::tableChanged (  QdbtSelection::change_t    op, int    row, int    col )  [virtual]

This function is being called whenever the table's geometry is being changed. The reason op as well as affected row and/or col is being passed.
