SplashScreen isn't displayed

D' you mean to use qDebug to see if pixmap.isNull() ?

In this case, yes. The list of possible use cases is endless, though.

[Salazaar]

I added line

qDebug() << "Is pixmap null:" << pixmap.isNull();

qDebug() << "Is pixmap null:" << pixmap.isNull();

To copy to clipboard, switch view to plain text mode 

and reached in console:
QObject::connect: No such signal QTimer::timeout()
Is pixmap null: true
So there's a problem with loading image.

Could you paste the contents of .qrc file and the output of "tree -f" executed in the project directory from command line? About the signal, you have already been advised more than once how to fix that.

[Salazaar]

Sure. Images.qrc:

<RCC>
<qresource prefix="/new/prefix1" >
<file>File.jpg</file>
<file>Poker.JPG</file>
<file>Poker.PNG</file>
<file>Tools.jpg</file>
<file>about.jpg</file>
<file>copy.jpg</file>
<file>cut.jpg</file>
<file>delete.jpg</file>
<file>delfile.jpg</file>
<file>exit.jpg</file>
<file>favicon.ico</file>
<file>find.jpg</file>
<file>font.jpg</file>
<file>help.jpg</file>
<file>mainlogo.jpg</file>
<file>new.jpg</file>
<file>paste.jpg</file>
<file>print.jpg</file>
<file>save.jpg</file>
<file>settings.jpg</file>
<file>sort.jpg</file>
</qresource>
</RCC>

And If I try tree -f I reach that there's no such command

[jpn]

Sure. Images.qrc:

So shouldn't it be something like:

QPixmap pixmap(":/new/prefix1/Poker.PNG");

QPixmap pixmap(":/new/prefix1/Poker.PNG");

To copy to clipboard, switch view to plain text mode 

And If I try tree -f I reach that there's no such command

I guess you're running some else Windows than XP/2000 then?

[Salazaar]

No, I've got XP. I tried your code - with result. Thanks. Now I have to solve problem with the signal

[jpn]

No, I've got XP

Oh, and actually it should be "tree /f" not "tree -f". The command should definitely be available in XP.
