This can be adjusted by calling setWordWrap(). Both - dynamic wrapping according to the visible width or a fixed number of - character or pixels is supported. - - The widget can be used to display text by calling setReadOnly(TRUE). - - The default key bindings are described in keyPressEvent(); they cannot - be customized except by inheriting the class. - - <img src=qmlined-m.png> <img src=qmlined-w.png> -*/ - -/* - \property TQtMultiLineEdit::numLines - \brief the number of lines in the multi-line edit - - numLines() returns the number of lines in the editor.

If -it returns TRUE, the contents have been edited, or setEdited( TRUE ) -has been called. - -setEdited() sets the edited flag of this line edit to \e e. The -edited flag is never read by TQtMultiLineEdit, but is changed to TRUE -whenever the user changes its contents. - -This is useful e.g. for things that need to provide a default value, -but cannot find the default at once.

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 TQtTableView 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 TQScrollView or TQListBox can - easily be made to do the job you need, we recommend subclassing - those widgets rather than TQtTableView. In addition, TQScrollView makes - it easy to have child widgets inside tables, which TQtTableView - doesn't support at all. - - \sa TQScrollView - \link guibooks.html#fowler GUI Design Handbook: Table\endlink -*/ - - -/* - Constructs a table view.
