Member Function Documentation

QString FlashCardEditor::authorName ( )

virtual

Access to author name of current editor.

Returns

Definition at line 249 of file flashcardeditor.cpp.

                                    {
  return m_ui->m_txtAuthor->lineEdit()->text();
}

bool FlashCardEditor::canGenerateApplications ( )

virtual

Specifies if template can generate applications or not.

Returns

Returns true if editor contains enough data for generating of applications.

Warning

This is used in cooperation with canGenerateStatusChanged(bool can_generate).

Reimplemented from TemplateEditor.

Definition at line 136 of file flashcardeditor.cpp.

                                              {

}

QString FlashCardEditor::generateBundleData ( )

virtual

Generates RAW data which represent data of this template.

Remarks

Generated data are stored in XML bundle file.
