• NODES_SELECTED

• NODES_ALL

The function GetNodeList() retrieves the nodes specified by the nodeScope, if IsSceneValid() was successful. For

example:

eligibleForSubmission = FarmAPI.IsSceneValid(

nodeScope = FarmAPI.NODES_ALL,

allowUnsavedChanges=False,

allowCapitalLetters=False,

allowDigits=False,

unwantedSymbols=["_"]

)

if eligibleForSubmission:

nodesForFarm = FarmAPI.GetNodeList()

If a scene fails the IsSceneValid() check, any errors and warnings are retrieved using GetErrorMessages() and

GetWarningMessages(). The following example displays any errors in a message box:

errorText = FarmAPI.GetErrorMessages()

if len(errorText) > 0:

UI4.Widgets.MessageBox.Warning('Error', \

' '.join(errorText))

return

The functions AddErrorMessage() and AddWarningMessage() are used to issue additional error messages. These

are only used when writing a custom dialog.
