Hello,
I’m new to Kodi so please don’t judge me too hard 
I’m trying to make custom Favourites for kodi, so I need to make few Windows and Dialogs.
So I created Custom_[window_name].xml file, created C++ class in xmbc/dialogs directory , add it to make files and CMakefiles.
Then add the C++ class to GUIWindowManager with Add method. Also assigned key for the Custom_windowname.xml files ID (1195).
When I start Kodi and press the key the window appears as it should, and the window manager initialize the class.
The problem is that the C++ class don’t activate OnInitWindow method when I press the key for window activation. It does not show any Log messages from my class OnInitWindow method.
P.S. I have inherited CGUIDIALOG and passed window ID and the file name of XML file to the constructor.
Where is the problem I cannot understand why it doesn’t call the method on window Initialization?
