Thanks a lot Bernhard for your answer.
This was the solution!
Instead of
/ composerView = diffList[0]//
// composition = self.composerView.composition()//
////composerView.composerViewHide.connect(self.operationOnTop)////
/
I tried
/*self.*composerView = diffList[0]//
//*self.*composition = *self.*composerView.composition()//
////*self.*composerView.composerViewHide.connect(self.operationOnTop)////
/
And now it works!! The signal is connected with the operationOnTop
function, and my form comes back in front of the main QGIS window after
the composer closure.
Thank you very much!
Best regards
Vincent

Hi,
I often had the problem that connecting to a signal did not work, too.
My solution always was to make the object which throws the signal an
object of the class
so instead of
QgsComposerView....
try
self.QgsComposerView....
I have no idea if this is generally true neither can did I investigate
why it worked in my cases

Hi all,
I'm running QGIS 2.0.1 on Ubuntu 12.04, 64 bits (installed with
ubuntugis-unstable repository).
I've created a form, which shows a composer when I click on a button.
This form stays active while the composer is showed, but is located
behind the QGIS main window.
I'd like it to come back in front of the screen when the composer is
closed by user.
After several web searchs and tests, it seems that the following
function works :
/def operationOnTop(self): //
//self.raise_() //
//self.activateWindow()/
My problem is to connect a « composer closed » signal with this
function.
I think the signal should be QgsComposerView.composerViewHide. I'm
right ?
* I tried to connect it with the above slot :
/QgsComposerView.composerViewHide.connect(self.operationOnTop)/
But QGIS returns :
AttributeError: 'PyQt4.QtCore.pyqtSignal' object has no attribute
'connect'
I can't understand this error message : all signals should have «
connect » attribute, right ?
* Trying with the old « connect » way :
/self.connect(QgsComposerView(), QtCore.SIGNAL('composerViewHide'),
self.operationOnTop)/
My plugin doesn't crash during loading, but nothing happens when I close
the composer.
I've added « print 'operationOnTop' » to the end of the function, to
test its loading. Apparently, the signal is not catched, as I have no
return in the Python pannel.
Can you see what I've missed in each case ?
Any help would be greatly appreciated.
Kind regards
PS : I've tried to make the connection in the class constructor :
/class OperationDialog(QtGui.QDialog): //
//def __init__(self, iface): //
//QtGui.QDialog.__init__(self) //
//self.ui = Ui_operation() //
//self.ui.setupUi(self) //
//self.iface = iface //
//self.canvas = self.iface.mapCanvas()//
//…//
//QgsComposerView.composerViewHide.connect(self.operationOnTop)//
///
Should I put it in the function which creates the composer?
