[SOLVED] Widget plugin ... Problem with enumeration

[yellowmat]

Hi,

I'm writing a new widget and I have some issu that I don't understand.

The aim of that widget is to configure a sound object. This class has some parameters and at least two properties (PlayMode and RestitutionMode) recorded in two variables which type is an enumeration.

My problem is in the functions that returns the value of those two variables. In my opinion the syntax is correct but the compilation failes so maybe it's due to something else that is linked with Q_ENUMS or Q_PROPERTY, I hope someone will be able to help me.

He are my questions :
What is wrong with my code ?
* The compilation errors I got are the following

./SoundConfigurator.cpp(122) C2143 : syntax error, missing ";" before 'tag::id'

./SoundConfigurator.cpp(122) C2143 : syntax error, missing ";" before 'tag::id'

To copy to clipboard, switch view to plain text mode 

./SoundConfigurator.cpp(122) C2501 : 'PlayMode' : missing storage class or type specifiers

./SoundConfigurator.cpp(122) C2501 : 'PlayMode' : missing storage class or type specifiers

To copy to clipboard, switch view to plain text mode 

* What is the use of Q_ENUMS and Q_PROPERTY ? (I read the documentation but the index does not find any entries for Q_ENUMS and Q_PROPERTY)

Thansk in advance

hoops, I forgot a question.

In a close future my class will be integrated into a plugin and will also have a member of type CFileChooser which is also a plugin I had Developped.

Do I need to do something special to add a CFileChooser member into (other than adding a #include directive) ?

Do I need to do something special into the plugin.h of my CSoundConfigurator to declare the CFileChooser plugin member ?

Thanks

hum, no one could help me ?

Could you post the relevant part of your code?

What is the use of Q_ENUMS and Q_PROPERTY ? (I read the documentation but the index does not find any entries for Q_ENUMS and Q_PROPERTY)

Try:

CSoundConfigurator::PlayMode CSoundConfigurator::getSoundPlayModeValue() const
{
	return soundPlayModeComboBox->currentItem();
}

CSoundConfigurator::PlayMode CSoundConfigurator::getSoundPlayModeValue() const
{
	return soundPlayModeComboBox->currentItem();
}
