Member Function Documentation

OnImportFileOpened()

bool anonymous_namespace{ProjectFileManager.cpp}::ImportProgress::OnImportFileOpened ( ImportFileHandle &  importFileHandle )

inlineoverridevirtual

Called by Importer when it attempts to import file using registered ImportPlugin instance Could be called more than once, but for each call there will be a complementary call to OnImportResult

Parameters

importFileHandle

file handle created by ImportPlugin instance

Returns

Implementation may return false to abort import process

Implements ImportProgressListener.
