QTimer::singleshot doesn't call SLOTs with arguments

[hulk]

hi all,

I want to execute my function "saveTraining()" 20 seconds after another function. I suppose a SingleShot-Timer to be the right choice.

If I call this command

QTimer::singleShot( 20000, this, SLOT(saveTraining()));

QTimer::singleShot( 20000, this, SLOT(saveTraining()));

To copy to clipboard, switch view to plain text mode 

my function "saveTraining()" is executed properly after 20 seconds. All works fine.

But if I try to commit an argument like in this command:

QTimer::singleShot( 20000, this, SLOT(saveTraining(5)));

QTimer::singleShot( 20000, this, SLOT(saveTraining(5)));

To copy to clipboard, switch view to plain text mode 

my function "saveTraining(int number)" isn't executed.


Infos:
-I also tried to commit other arguments, like QString or QPointF without success.
-The compiler is compiling this project without any errors or warnings
-There is the right prototyp of my function in the .h-File
-I also tried to commit a "Klassenvariable" without success. I don't know the right english word for "Klassenvariable". It's a variable which is declared staticly in the class so that every object of this class has this variable. Maybe "membervariable" is the right word for it.
-Version Qt 4.1.2 Open Source


Where is my mistake? Could it be possible that it isn't allowed to commit arguments in a SingleShot-Timer? I didn't see such an info in the documentation. I hope you can help me. Sorry for my probably bad english.

You cannot put parameter values to signals and slots in the connect statement.
You can only put parameter types, which need to match exactly for the signal and the slot (exception: a slot can have less parameters than the signal..)

If you want one timer to emit some value and another timer to emit some different value, you can use a QSignalMapper.
