Hi,
I'm trying to use vtkPythonProgrammableFilter to implement a reader in
Python. The problem is in passing the filename (form the filebrowser
dialog) to the python script (the RequestData script). I need a method
in vtkPythonProgrammableFilter with one char * argument that can behave
like SetFileName(char *) to set this method to command property in the
XML file. Unfortunately, this scheme is not compatible with SetParameter
methods of vtkPythonProgrammableFilter. Finally, I find a hack using the
method SetProgressText (from vtkAlgorithm) instead of SetFileName. So my
XML looks like:
<ServerManagerConfiguration>
<ProxyGroup name="sources">
<SourceProxy name="EGrid Reader"
class="vtkPythonProgrammableFilter"
label="EGrid Reader">
<StringVectorProperty
name="FileName"
animateable="0"
command="SetProgressText"
number_of_elements="1"
panel_visibility="advanced">
<FileListDomain name="files"/>
</StringVectorProperty>
<IntVectorProperty command="SetOutputDataSetType"
default_values="4"
name="OutputDataSetType"
number_of_elements="1"
panel_visibility="never">
</IntVectorProperty>
<StringVectorProperty
name="Script"
command="SetScript"
number_of_elements="1"
default_values="print self.GetProgressText()"
panel_visibility="advanced">
<Hints>
<Widget type="multi_line"/>
</Hints>
</StringVectorProperty>
<Hints>
<ReaderFactory extensions="egrid"
file_description="Eclipse mesh File Format" />
</Hints>
</SourceProxy>
</ProxyGroup>
</ServerManagerConfiguration>
Is there a beter way how to pass the filename to the script? If not,
could a SetFileName method be implemented in vtkPythonProgrammableFilter
that simply calls
SetParameter("FileName", the_path)
?
Thank you for a help,
Jan
