Dear all,

I am trying to write a custom GUI-block using QT. I was looking into the QT 
tree-module blocks in order to understand how the QApplication-instance that is 
created in the GRC-generated Python-file is used when setting up a generic GR 
qt-GUI (e.g. a standard  frequency sink).


Apparently the GR QT blocks use the "qApp" - MACRO that checks if there is 
already a QApplication instance. As one is spawned in the main python file, the 
GT QT Block recognizes this instance and returns a reference to some widget 
that is supposed to be displayed in the GUI associated with the QApplication 
instance.


I tried to mimic that and also check for "qApp". However, the QApplication 
instance is NOT regognized in my OOT QT block.


Maybe, there is some kind of collision of Qt-versions in the background since I 
am building my GUI with Qt5 but I cannot find any solution....



If you have any idea, I would appreciate any help.


Thanks in advance.
