What this files to represent

[Naveen]

These are the files I found in Qt Source code....

qeffects.cpp and qeffects_p.h are found in the "gui" folder of the "src"

I want to use these files in my application ....
As far as the information i have on these files is that these file are used to create some fading effect in our application...but I'm not able to understand how to used them in my application...

Thanks
Naveen.....

It is possible to use them, right. Eg. something like this:

#include <Qt/private/qeffects_p.h>
 
qFadeEffect(fadeWidget, 300);
qScrollEffect(scrollWidget, 300);

#include <Qt/private/qeffects_p.h>

qFadeEffect(fadeWidget, 300);
qScrollEffect(scrollWidget, 300);

To copy to clipboard, switch view to plain text mode 

But as the header file says, it is not intended or suggested to use them:

//
// W A R N I N G
// -------------
//
// This file is not part of the Qt API. It exists for the convenience
// of qeffects.cpp, qcombobox.cpp, qpopupmenu.cpp and qtooltip.cpp.
// This header file may change from version to version without notice,
// or even be removed.
//
// We mean it.
//

Of course, you could "adapt" some hints from their solutions and implement something similar by yourself

I tried to include it , but it compile error with message " no such file".

suffix "_p.h" means private header! This header is for internal (Qt) use only (to maintain binary compatibility in a future). NEVER ever use that (unless you are modifying Qt code)!
Check Qt documentation about effects. QGraphicsEffect
Check this: QWidget::setGraphicsEffect

It means your include path is not set properly.
