+/**
+ * @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().
