Problems with export using Windows 11
There is a bug under Qt and Windows
The BuildTree function uses
# Get world volume from document tree widget
worldObj = FreeCADGui.Selection.getSelection()[0]
tree = FreeCADGui.getMainWindow().findChildren(QtGui.QTreeWidget)[0]
it = QtGui.QTreeWidgetItemIterator(tree)
Which returns correct values under Linux and MacOS but under Windows Returns None
Hi @KeithSloan
I encountered the same problem: https://github.com/KeithSloan/GDML/issues/147#issue-2568794335
The version I used is：
OS: macOS 14.3
Architecture: arm64
Version: 1.0.0.39109 (Git) Conda
Build type: Release
Branch: (HEAD detached at 1.0.0)
Hash: 2fcc5317fe3aee96ca73475986a577719fc78e20
Python 3.11.10, Qt 5.15.15, Coin 4.0.3, Vtk 9.3.0, OCC 7.8.1
Locale: C/Default (C)
Stylesheet/Theme/QtStyle: unset/FreeCAD Classic/Qt default
Installed mods:
* GDML.zip
* GDML 2.0.1Beta
I made a modification to the "def buildDocTree():" function, here is my code:
def buildDocTree():
from PySide import QtWidgets
global childObjects
childObjects = {} # dictionary of list of child objects for each object
# TypeIds that should not go in to the tree
skippedTypes = ["App::Origin", "Sketcher::SketchObject", "Part::Compound"]
def addDaughters(item: QtWidgets.QTreeWidgetItem):
print (f"--------addDaughters {item.text(0)}")
objectLabel = item.text(0)
object = App.ActiveDocument.getObjectsByLabel(objectLabel)[0]
if object not in childObjects:
childObjects[object] = []
for i in range(item.childCount()):
childItem = item.child(i)
treeLabel = childItem.text(0)
try:
childObject = App.ActiveDocument.getObjectsByLabel(treeLabel)[0]
objType = childObject.TypeId
if objType not in skippedTypes:
childObjects[object].append(childObject)
addDaughters(childItem)
except Exception as e:
print(e)
return
# Get world volume from document tree widget
worldObj = FreeCADGui.Selection.getSelection()[0]
# tree = FreeCADGui.getMainWindow().findChildren(QtGui.QTreeWidget)[0]
# it = QtGui.QTreeWidgetItemIterator(tree)
mw1 = FreeCADGui.getMainWindow()
print (f"---------Number of trees {len(mw1.findChildren(QtGui.QTreeWidget))}")
treesSel = mw1.findChildren(QtGui.QTreeWidget)
print (f"---------Number of trees {len(treesSel)}")
doc = FreeCAD.ActiveDocument
found = False
for tree in treesSel:
print(f"--------Tree {tree.objectName()}")
items = tree.selectedItems()
for item in items:
treeLabel = item.text(0)
print(f"--------Item {treeLabel}")
print(f"--------Doc.Label {doc.Label}")
# if not found:
# if treeLabel != doc.Label:
# continue
# found = True
try:
objs = doc.getObjectsByLabel(treeLabel)
print(f"--------Objects {objs}")
if len(objs) == 0:
continue
obj = objs[0]
if obj == worldObj:
print(f"--------World Object {obj.Label}")
# we presume first app part is world volume
addDaughters(item)
break
except Exception as e:
print(e)
FreeCADobject = None
I'm not familiar with FreeCad's API, but it seems to work fine in my environment.
Hope it can provide some reference.
I had exactly the same problem on my Linux Debian Bookworm (working with FreeCAD 1.0 (AppImage). Now it looks good with the exact same as proposed modifications of the file exportGDML.py. Big thanks to zhangcaocao for the proposal. It not only provides reference but it HELPS a lot.
And for Keith, it is not only under Windows... To produce the error:
- in FreeCAD activate GDML workbench
- Create a new empty file
- select world Vol
- export to GDML (choosing directory and so on...)
...snip from error messages...
