[Qt-interest] capture screen

Hi pengliang,
hi all,

The code needs a lot of cleanup because if is unnecessary complicated.
The function windowHideShow is almost useless.

You have created some really funny things here:

this-hide(); LOL

You take the address of the widget and subtract the result of
hide of it and throw the result away. Funny.

I think you meant this->hide();
You do the same here: while(this-isHidden())

NEVER EVER use this inside a class without the need of
doing so! The only reason to use this is to give another
class a pointer to your instance.
The use of this is a disease that occur since python programmers
try to use C++ (in python you have to do it that way with self).

Here some other points:

1. Why do you want to toggle isHideWnd. No need for that.
   You have two variables doing the same thing
2. You try to call functions twice! One time with this, the
   other time correct.

Clean up the code first and REMOVE all the useless "this".


Best Regards,



Carsten
