Re: [IronPython] Error Iterating
Curt & David,
Thanks for the help! Should have figured that one out. :)

Re: [IronPython] Error Iterating
You need to instantiate InstalledFontCollection in order to use its Families
field directly. The code sample you sent gets Families from the type
InstalledFontCollection, rather than an instance thereof, and thus tries to
iterate over a property descriptor. Try the following:
>>> for f in InstalledFontCollection().Families:
... print f.Name
...
Good luck,
- David

Subject: [IronPython] Error Iterating
Hello All,
I'm working through a book and one of the exercise involves
building comboBox filled with the names of the installed
FontFamilies. The code and error are:
>>> import clr
>>> clr.AddReference("System.Drawing")
>>> from System.Drawing.Text import InstalledFontCollection
>>> for f in InstalledFontCollection.Families:
... print f.Name
...
...
TypeError: iteration over non-sequence of type getset_descriptor
The MSDN says that InstalledFontCollection.Families should be an Array
of FontFamily objects which I thought I could step through. What did
I do wrong here?
TIA,
David

Re: [IronPython] Error Iterating
You need to instantiate the InstalledFontCollection because "Families" is
not a static property.
>>> import clr
>>> clr.AddReference('System.Drawing')
>>> from System.Drawing.Text import InstalledFontCollection
>>> for f in InstalledFontCollection().Families:
... print f.Name
... break
...

[IronPython] Error Iterating
Hello All,
I'm working through a book and one of the exercise involves
building comboBox filled with the names of the installed
FontFamilies. The code and error are:
>>> import clr
>>> clr.AddReference("System.Drawing")
>>> from System.Drawing.Text import InstalledFontCollection
>>> for f in InstalledFontCollection.Families:
... print f.Name
...
...
TypeError: iteration over non-sequence of type getset_descriptor
The MSDN says that InstalledFontCollection.Families should be an Array
of FontFamily objects which I thought I could step through. What did
I do wrong here?
TIA,
David
