/**
* A Widget which allows the user to select a character of a
* specified font in a table
*
* You can specify the font whoes characters should be displayed via
* @ref setFont(). Using @ref enableFontCombo() you can allow the
* user to choose the font from a combob-box. As only 256 characters
* are displayed at once in the table, using the spinbox on the top
* the user can choose starting from which chracater the table
* displayes them. This spinbox also can be enabled or disabled using
* @ref enableTableSpinBox().
*
* KCharSelect supports keyboard and mouse navigation. Click+Move
* selects always the character below the mouse cursor. Using the
* arrow keys the focus mark is moved around and with pressing RETURN
* or SPACE the cell which contains the focus mark gets selected.
*
* To get the current selected character, use the @ref chr()
* method. You can set the character which should be displayed with
* @ref setChar() and the table number which should be displayed with
* @ref setTableNum().
