/**
* @short Character selection widget
*
* This widget allows the user to select a character of a
* specified font in a table
*
* \image html kcharselect.png "Character Selection Widget"
*
* You can specify the font whose characters should be displayed via
* setFont() or in the constructor. Using 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 character the table
* displays them. This spinbox also can be enabled or disabled using
* enableTableSpinBox().
*
* KCharSelect supports keyboard and mouse navigation. Click+Move
* always selects the character below the mouse cursor. Using the
* arrow keys moves the focus mark around and pressing RETURN
* or SPACE selects the cell which contains the focus mark.
*
* To get the current selected character, use the chr()
* method. You can set the character which should be displayed with
* setChar() and the table number which should be displayed with
* setTableNum().
