[Paraview-developers] Callback not being called when deselecting an item in the GUI of a plugin

[Cory Quammen]

Daniel,

The signature for SetAttributeEnabled() should be

void SetAttributeEnabled(const char * name, int status)

The status argument tells whether the attribute is enabled or not.

Also, your XML should be

<StringVectorProperty command="SetAttributeEnabled"
                            element_types="2 0"
                            label="Enabled attributes"
                            name="CellArrayStatus"
                            number_of_elements="0"
                            number_of_elements_per_command="2"
                            repeat_command="1">
<ArrayListDomain name="array_list">
   <RequiredProperties>
   <Property name="Input" function="Input" />
   </RequiredProperties>
</ArrayListDomain>
</StringVectorProperty>

The element_types indicate the type of argument (2 for char string, 0 for int).

Please see ParaView/ParaViewCore/ServerManager/SMApplication/Resources/readers.xml
lines 241 - 262 for more hints that might help you.

Hope that helps,
Cory
