problems implementing own widget

[Mohammed Sameer <Uniball gmx net>]

Hi all,
As the subject says, I'm having problems implementing a widget for my text editor, Everything seems OK to me, but compiling & running the test program yields nothing, I'm sure I'm missing something here.
Can anyone kindly help me or point me to the correct way ??

Best regards,
