The cells are identified + with a row index and a column index. The top-left cell is in row 0, + column 0. + + The behavior of the widget can be finely tuned using + setTableFlags(); a typical subclass will consist of little more than a + call to setTableFlags(), some table content manipulation and an + implementation of paintCell(). Subclasses that need cells with + variable width or height must reimplement cellHeight() and/or + cellWidth(). Use updateTableSize() to tell QtTableView when the + width or height has changed. + + When you read this documentation, it is important to understand the + distinctions among the four pixel coordinate systems involved. + + \list 1 + \i The \e cell coordinates. (0,0) is the top-left corner of a cell. + Cell coordinates are used by functions such as paintCell(). + + \i The \e table coordinates. (0,0) is the top-left corner of the cell at + row 0 and column 0. These coordinates are absolute; that is, they are + independent of what part of the table is visible at the moment. They are + used by functions such as setXOffset() or maxYOffset(). + + \i The \e widget coordinates. (0,0) is the top-left corner of the widget, + \e including the frame. They are used by functions such as repaint(). + + \i The \e view coordinates. (0,0) is the top-left corner of the view, \e + excluding the frame. This is the least-used coordinate system; it is used by + functions such as viewWidth(). \endlist + + It is rather unfortunate that we have to use four different + coordinate systems, but there was no alternative to provide a flexible and + powerful base class. + + Note: The row,column indices are always given in that order, + i.e., first the vertical (row), then the horizontal (column). This is + the opposite order of all pixel operations, which take first the + horizontal (x) and then the vertical (y). + + <img src=qtablevw-m.png> <img src=qtablevw-w.png> + + \warning the functions setNumRows(), setNumCols(), setCellHeight(), + setCellWidth(), setTableFlags() and clearTableFlags() may cause + virtual functions such as cellWidth() and cellHeight() to be called, + even if autoUpdate() is FALSE. This may cause errors if relevant + state variables are not initialized. + + \warning Experience has shown that use of this widget tends to cause + more bugs than expected and our analysis indicates that the widget's + very flexibility is the problem. If QScrollView or QListBox can + easily be made to do the job you need, we recommend subclassing + those widgets rather than QtTableView. In addition, QScrollView makes + it easy to have child widgets inside tables, which QtTableView + doesn't support at all. + + \sa QScrollView + \link guibooks.html#fowler GUI Design Handbook: Table\endlink +*/ + + +/* + Constructs a table view.
