|

*
|
|
* \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().
