.SH DESCRIPTION
The QTableSelection class provides access to a selected area in a QTable.
.PP
The selection is a rectangular set of cells. One of the rectangle's cells is called the anchor cell; this is the cell that was selected first. The init() function sets the anchor and the selection rectangle to exactly this cell; the expandTo() function expands the selection rectangle to include additional cells.
.PP
There are various access functions to find out about the area: anchorRow() and anchorCol() return the anchor's position; leftCol(), rightCol(), topRow() and bottomRow() return the rectangle's four edges. All four are part of the selection.
.PP
A newly created QTableSelection is inactive -- isActive() returns FALSE. You must use init() and expandTo() to activate it.
.PP
See also QTable, QTable::addSelection(), QTable::selection() and Advanced Widgets.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QTableSelection::QTableSelection ()"
Creates an inactive selection. Use init() and expandTo() to activate it.
.SH "int QTableSelection::anchorCol () const"
Returns the anchor column of the selection.
.PP
See also anchorRow() and expandTo().
.SH "int QTableSelection::anchorRow () const"
Returns the anchor row of the selection.
.PP
See also anchorCol() and expandTo().
.SH "int QTableSelection::bottomRow () const"
Returns the bottom row of the selection.
.PP
See also topRow(), leftCol() and rightCol().
.SH "void QTableSelection::expandTo ( int row, int col )"
Expands the selection to include cell \fIrow\fR, \fIcol\fR. The new selection rectangle is the bounding rectangle of \fIrow\fR, \fIcol\fR and the previous selection rectangle. After calling this function the selection is active.
.PP
If you haven't called init(), this function does nothing.
.PP
See also init() and isActive().
.SH "void QTableSelection::init ( int row, int col )"
Sets the selection anchor to cell \fIrow\fR, \fIcol\fR and the selection to contain only this cell.
.PP
To extend the selection to include additional cells, call expandTo().
.PP
See also isActive().
.SH "bool QTableSelection::isActive () const"
Returns whether the selection is active or not. A selection is active after init() and expandTo() have been called.
.SH "int QTableSelection::leftCol () const"
Returns the left column of the selection.
.PP
See also topRow(), bottomRow() and rightCol().
.SH "bool QTableSelection::operator== ( const QTableSelection & s ) const"
Returns TRUE if \fIs\fR includes the same cells as the selection; otherwise returns FALSE.
.SH "int QTableSelection::rightCol () const"
Returns the right column of the selection.
.PP
See also topRow(), bottomRow() and leftCol().
.SH "int QTableSelection::topRow () const"
Returns the top row of the selection.
.PP
See also bottomRow(), leftCol() and rightCol().
