Detailed Description

Encapsulation of a tabular's selection state.

Thie class describes the interface for classes containing information about the tabular's selection.

Member Enumeration Documentation

enum QdbtSelection::change_t

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

QdbtSelection::~QdbtSelection (    )  [virtual]

Destructor for the selection instance

QdbtSelection::QdbtSelection (  QdbtBaseTabular *    ctx )  [protected]

The Constructor creates a QdbtSelection instance for the tabular widget context. 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). This can either be done by the surrounding program or by adding the command tableChanged( DIMENSION_SET, QdbtSelection::context()->numRows(), QdbtSelection::context()->numCols() ); as the last line of the constructor of the derived class.

Member Function Documentation

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

Query of the cell at position row, col is selectable. Implemented in QdbtSingleCellSelection, QdbtCellSelection, QdbtRowSelection, and QdbtSingleRowSelection.

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

The tabular components use this member function to query, if the cell at row, col is selected or not. Implemented in QdbtSingleCellSelection, QdbtCellSelection, QdbtRowSelection, and QdbtSingleRowSelection.

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

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

void QdbtSelection::dump (    )  [virtual]

Dump servers to print the content of a selection object to stderr. The default implementation prints selection-state and selectability as accessed by cellSelected() and cellSelectable(). Reimplemented in QdbtRowSelection, and QdbtSingleRowSelection.

void QdbtSelection::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 in QdbtSingleCellSelection, QdbtCellSelection, QdbtRowSelection, and QdbtSingleRowSelection.

void QdbtSelection::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 in QdbtSingleCellSelection, QdbtCellSelection, QdbtRowSelection, and QdbtSingleRowSelection.

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

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.

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

Set if the cell at position row, col is selectable or not to sel. Implemented in QdbtSingleCellSelection, QdbtCellSelection, QdbtRowSelection, and QdbtSingleRowSelection.

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

Set the selection state of the cell at position row, col to sel. Implemented in QdbtSingleCellSelection, QdbtCellSelection, QdbtRowSelection, and QdbtSingleRowSelection.

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

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]

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]

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]

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.
