The Q3TableSelection class provides access to a selected area in a Q3Table .
The selection is a rectangular set of cells in a Q3Table . 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.
There are various access functions to find out about the area: anchorRow () 和 anchorCol () return the anchor's position; leftCol (), rightCol (), topRow () 和 bottomRow () return the rectangle's four edges. All four are part of the selection.
A newly created Q3TableSelection is inactive -- isActive () returns false. You must use init () 和 expandTo () to activate it.

Creates an inactive selection. Use init () 和 expandTo () to activate it.
Creates an active selection, starting at start_row and start_col , ending at end_row and end_col .
Returns the anchor column of the selection.
另请参阅 anchorRow () 和 expandTo ().
Returns the anchor row of the selection.
另请参阅 anchorCol () 和 expandTo ().
Returns the bottom row of the selection.
另请参阅 topRow (), leftCol ()，和 rightCol ().
Expands the selection to include cell row , col . The new selection rectangle is the bounding rectangle of row , col and the previous selection rectangle. After calling this function the selection is active.
If you haven't called init (), this function does nothing.
Sets the selection anchor to cell row , col and the selection to only contain this cell. The selection is not active until expandTo () 被调用。
To extend the selection to include additional cells, call expandTo ().
另请参阅 isActive ().
Returns whether the selection is active or not. A selection is active after init () and expandTo () have been called.
Returns whether the selection is empty or not.
Returns the left column of the selection.
另请参阅 topRow (), bottomRow ()，和 rightCol ().
Returns the number of columns in the selection.
另请参阅 numRows ().
Returns the number of rows in the selection.
另请参阅 numCols ().
Returns the right column of the selection.
另请参阅 topRow (), bottomRow ()，和 leftCol ().
Returns the top row of the selection.
另请参阅 bottomRow (), leftCol ()，和 rightCol ().
返回 true 若 s does not include the same cells as the selection; otherwise returns false.
返回 true 若 s includes the same cells as the selection; otherwise returns false.
