|
|
The QTableSelection class provides access to a selected area in a
|
||
|
|
<a href="qtable.html">QTable</a>.
|
||
|
|
|
||
|
|
<p>
|
||
|
|
|
||
|
|
<p> The selection is a rectangular set of cells in a QTable. One of
|
||
|
|
the rectangle's cells is called the anchor cell; this is the cell
|
||
|
|
that was selected first. The <a href="#init">init</a>() function sets the anchor and
|
||
|
|
the selection rectangle to exactly this cell; the <a href="#expandTo">expandTo</a>()
|
||
|
|
function expands the selection rectangle to include additional
|
||
|
|
cells.
|
||
|
|
<p> There are various access functions to find out about the area:
|
||
|
|
<a href="#anchorRow">anchorRow</a>() and <a href="#anchorCol">anchorCol</a>() return the anchor's position;
|
||
|
|
<a href="#leftCol">leftCol</a>(), <a href="#rightCol">rightCol</a>(), <a href="#topRow">topRow</a>() and <a href="#bottomRow">bottomRow</a>() return the
|
||
|
|
rectangle's four edges. All four are part of the selection.
|
||
|
|
<p> A newly created QTableSelection is inactive -- <a href="#isActive">isActive</a>() returns
|
||
|
|
FALSE. You must use init() and expandTo() to activate it.
|
||
|
|
