Overview

Classes

pyarchinit_GPKG

No description available. A QGIS QDialog subclass that provides a user interface for exporting selected map layers from the QGIS layer tree into GeoPackage (.gpkg) files. It supports exporting both vector layers via QgsVectorFileWriter and raster layers via QgsRasterFileWriter, handling both new file creation and appending to existing GeoPackage files. The dialog is locale-aware, adapting its message strings to Italian, English, or German based on the current QGIS user locale setting, and applies a theme via ThemeManager.

Inherits from: QDialog, MAIN_DIALOG_CLASS

Methods

init(self, iface)

Initializes the GeoPackage import dialog by calling the parent class constructors and configuring the UI via setupUi. Applies the current application theme using ThemeManager.apply_theme and attaches a theme toggle button to the form. Connects the toolButton clicked signal to the setPath slot for file path selection.

setPath(self)

Opens a save file dialog prompting the user to specify a file path for a GeoPackage (.gpkg) file. If a valid path is selected, it updates the lineEdit widget with the chosen path and stores the value in QgsSettings.

on_pushButton_gpkg_pressed(self)

No description available. Handles the press event of the GPKG export button by retrieving the currently selected layers from the layer tree view and the target GeoPackage file path from the line edit field. For each selected vector layer, it writes the layer to the specified GeoPackage file using QgsVectorFileWriter.writeAsVectorFormat, replacing spaces in layer names with underscores; if the target file already exists, layers are added using the CreateOrOverwriteLayer action, otherwise the file is created first before subsequent layers are appended. Upon completion, a localized message box is displayed indicating whether the import succeeded or failed, or warning the user if no layers were selected.

on_pushButton_gpkg2_pressed(self)

No description available. Handles the press event of the pushButton_gpkg2 button by appending the first selected layer from the layer tree view as a raster subdataset into an existing GeoPackage file specified by lineEdit. It opens the target GeoPackage via GDAL, constructs a QgsRasterFileWriter configured with the gpkg output format and APPEND_SUBDATASET=YES, and writes the raster data through a QgsRasterPipe containing a QgsRasterProjector. A warning dialog is displayed to indicate whether the import completed successfully or failed.
