[Closed] Python and PyQt in 3dsMax

Ha, another issue

I’m new to Qt and PyQt, so, please, bear with me

But, I tried to create a simple UI in the Qt Designer and I saved it as a .ui file on C:\

However, when I try to run this Python code:

from blur.wingui  import Dialog

from PyQt4.QtCore import SIGNAL           # Signal mapping method for Qt
from PyQt4.QtGui  import QTreeWidgetItem  # Don't need the other imports, all loaded in the Ui file

import PyQt4.uic # Loader file

from Py3dsMax     import mxs              # Bring in the maxscript module

class ObjectItem( QTreeWidgetItem ):
	def __init__( self, msobject ):
		QTreeWidgetItem.__init__( self, [ msobject.name ] )
		self._msobject = msobject
		
		# Add the children of this item
		for child in msobject.children:
			self.addChild( ObjectItem( child ) )

	def msobject( self ):
		return self._msobject

class TestDialog( Dialog ):
	def __init__( self ):
		Dialog.__init__( self )
		PyQt4.uic.loadUi( 'C:\	st.ui', self )

		self._connect() # Connect the signals/slots
		self.refresh()  # Load the data

# Create the dialog
dialog = TestDialog()
dialog.show()

I get a TypeError:

TypeError: ('Wrong base class of toplevel widget', (<class '__main__.TestDialog'>, 'QMainWindow'))

Anyone knows what might be the problem?

You used a window instead of a dialogue in the .ui file hence it is a different class.

Here’s Working code. What i did is replace instances of Dialog with Window (including the import statement of course!). On a second note it would still error out because you are calling methods that you removed from the class declatration. I commented them out (refresh and _connect).

from blur.wingui  import Window

from PyQt4.QtCore import SIGNAL           # Signal mapping method for Qt
from PyQt4.QtGui  import QTreeWidgetItem  # Don't need the other imports, all loaded in the Ui file

import PyQt4.uic # Loader file

from Py3dsMax     import mxs              # Bring in the maxscript module

class ObjectItem( QTreeWidgetItem ):
	def __init__( self, msobject ):
		QTreeWidgetItem.__init__( self, [ msobject.name ] )
		self._msobject = msobject
		
		# Add the children of this item
		for child in msobject.children:
			self.addChild( ObjectItem( child ) )

	def msobject( self ):
		return self._msobject

class TestDialog( Window ):
	def __init__( self ):
		Window.__init__( self )
		PyQt4.uic.loadUi( 'C:\	st.ui', self )

		#self._connect() # Connect the signals/slots
		#self.refresh()  # Load the data

# Create the dialog
dialog = TestDialog()
dialog.show()

Hope that helps,

@ ypuech

Thanks for the windows icon code – I’ll include it in the next release, its very cool – works in 3dsMax and XSI. Though, it doesn’t seem to work in x64 bit, just x32.

@ instinct-vfx

Thanks for the tutorial – I uploaded it to the wiki:
http://code.google.com/p/blur-dev/wiki/Py3dsMaxCOMExecute?ts=1256323833&updated=Py3dsMaxCOMExecute

Thanks guys for helping debug and build this!

Eric

Also, we’re in the process of porting our tools over to a new PyQt based treegrunt that’ll run in both XSI & 3dsMax, so we will be updating our tools download soon enough.

Thanks guys!

@loocas:

I forgot to add in the modification the import of SendMessage from win32gui module:

from win32gui import FindWindow, SendMessage, GetClassLong, GetIconInfo
 from win32con import WM_GETICON, GCL_HICONSM, GCL_HICON

@ehulser:

I will try to make the icon code works under x64.

Hey Eric!
Thanks for this cant wait to play with it! Now we can make some nifty node based ui’s using qpainter…
Cheers,
Lukas

@ lukashi

I would recommend using the QGraphicsScene & QGraphicsView

We’ve been developing our own node based GUI’s using them and they are quite powerful, pretty much designed to handle such things.

At some point we’ll be releasing that out as well…

Eric

Ooops ya thats what i meant! Looking forward to those node based tools when they are ready!

Now that sounds pretty cool Eric! If you dont mind me asking did you develop the node system as a plugin to Qt with PyQt bindings or completely in PyQt?

Regards,
Thorsten
