+# This file contains all dialogs that the unit tests in the module

+# workdir/screenshots using the pattern of the ui-file name.
+#
+# Syntax:
+# - emty lines are allowed
+# - lines starting with '#' are treated as comment
+# - all other lines should contain a *.ui filename in the same
+#   notation as in the dialog constructors (see code)
+
+#
+# The 'known' dialogs which have a hard-coded representation
+# in registerKnownDialogsByID/createDialogByID
+#
+
+# No known dialogs in formula for now
+
+#
+# Dialogs without a hard-coded representation. These will
+# be visualized using a fallback based on VclBuilder
+#
+
+# currently deactivated, leads to problems and the test to not work
+# This is typically a hint that these should be hard-coded in the
+# test case since they need some document and model data to work
