Overview

This file contains 6 documented elements.

Classes

pyarchinit_doc_preview

No description available. A QDialog subclass that provides a preview interface for documentation records stored in the pyarchinit_documentazione database table. On initialization, it establishes a database connection, applies the active UI theme, and renders a map preview using a QgsMapCanvas widget populated via pyQGIS.loadMapPreviewDoc. The class holds class-level state for the current record index, data list, and file paths used by the pyArchInit documentation system.

Inherits from: QDialog, MAIN_DIALOG_CLASS

Methods

init(self, iface, docstr)

Initializes the form widget by calling the parent constructor, setting up the UI, and applying the current theme along with a theme toggle button. Configures a QgsMapCanvas instance with a white background and integrates it into the layout alongside the document preview widget, then calls draw_preview() to render the initial preview. Stores the provided iface and docstr references, instantiates a Pyarchinit_pyqgis object, and attempts a database connection via DB_connect(), silently suppressing any exceptions that occur.

DB_connect(self)

No description available. Establishes a database connection by instantiating a Connection object and retrieving its connection string via conn_str(). It then obtains a database manager instance using get_db_manager() with the singleton pattern enabled, assigning the result to self.DB_MANAGER. If an exception occurs during this process, a warning dialog is displayed to the user containing the error details.

draw_preview(self)

No description available. Constructs a GID filter string using the current record's ID from ID_TABLE and DATA_LIST, then loads the corresponding map preview layers via self.pyQGIS.loadMapPreviewDoc. The retrieved layers are displayed in a warning dialog listing their names, applied to self.mapPreview, and the view is zoomed to the full extent of the loaded layers.

testing(self, name_file, message)

No description available. Opens a file at the path specified by name_file in write mode ('w'), writes the string representation of message to it, then closes the file. Both name_file and message are explicitly cast to str before use. This method does not return a value.
