|
|---|
| 61 | The QTableSelection class provides access to a selected area in a
|
|---|
| 62 | <a href="qtable.html">QTable</a>.
|
|---|
| 63 |
|
|---|
| 64 | <p>
|
|---|
| 65 |
|
|---|
| 66 | <p> The selection is a rectangular set of cells in a QTable. One of
|
|---|
| 67 | the rectangle's cells is called the anchor cell; this is the cell
|
|---|
| 68 | that was selected first. The <a href="#init">init</a>() function sets the anchor and
|
|---|
| 69 | the selection rectangle to exactly this cell; the <a href="#expandTo">expandTo</a>()
|
|---|
| 70 | function expands the selection rectangle to include additional
|
|---|
| 71 | cells.
|
|---|
| 72 | <p> There are various access functions to find out about the area:
|
|---|
| 73 | <a href="#anchorRow">anchorRow</a>() and <a href="#anchorCol">anchorCol</a>() return the anchor's position;
|
|---|
| 74 | <a href="#leftCol">leftCol</a>(), <a href="#rightCol">rightCol</a>(), <a href="#topRow">topRow</a>() and <a href="#bottomRow">bottomRow</a>() return the
|
|---|
| 75 | rectangle's four edges. All four are part of the selection.
|
|---|
| 76 | <p> A newly created QTableSelection is inactive -- <a href="#isActive">isActive</a>() returns
|
|---|
| 77 | FALSE. You must use init() and expandTo() to activate it.
|
|---|
| 78 | <p> <p>See also <a href="qtable.html">QTable</a>, <a href="qtable.html#addSelection">QTable::addSelection</a>(), <a href="qtable.html#selection">QTable::selection</a>(), <a href="qtable.html#selectCells">QTable::selectCells</a>(), <a href="qtable.html#selectRow">QTable::selectRow</a>(), <a href="qtable.html#selectColumn">QTable::selectColumn</a>(), and <a href="advanced.html">Advanced Widgets</a>.
