FilterMate v4.6.3

FilterMate v4.6.3

i18n - 34 Languages & Live Language Switching

Expanded internationalization from 22 to 34 languages and fixed live language switching.

New Languages (+12)

• 🇰🇷 Korean (ko), 🇯🇵 Japanese (ja), 🇸🇦 Arabic (ar), 🇹🇭 Thai (th)
• 🇺🇦 Ukrainian (uk), 🇨🇿 Czech (cs), 🇷🇴 Romanian (ro), 🇬🇷 Greek (el)
• 🇭🇺 Hungarian (hu), 🇧🇬 Bulgarian (bg), 🇲🇾 Malay (ms), 🏴 Catalan (ca)

Bug Fixes

• Live language switching: Changing language from config or QGIS settings now retranslates the entire UI immediately (.ui file strings, indicator tooltips, buffer tooltips, combo/picker tooltips, menu/toolbar actions)
• retranslate_all_ui(): New unified retranslation method with reentrant guard, called from config UI and QEvent.LanguageChange
• changeEvent(LanguageChange): Dockwidget now handles Qt language change events, covering QGIS locale changes without going through FilterMate config
• retranslate_actions(): Menu and toolbar action texts are now retranslated on language change
• app_initializer._retranslate_ui(): Delegates to unified retranslate_all_ui() for consistency

Bug Fixes - Feature Picker & Exploring

Multiple fixes to the feature picker widget and exploring sidebar for improved stability and usability.

Bug Fixes

• Feature picker debounce: Store FID instead of C++ QgsFeature object to prevent crashes from dangling references
• Feature picker refresh: Properly refresh picker when display field changes
• Feature picker browser buttons: Fix next/prev browser buttons initialization
• Exploring sidebar: Always-enabled identify/zoom buttons + debounce feature picker typing

New

• Edit mode popup: Warning popup before filter/unfilter operations when a layer is in edit mode
• i18n: All user-facing strings wrapped and translated, 22 languages at 100%
• Config harmonization: Single source of truth config system with backward-compatible helpers

Changes

• Migrate plugin for QGIS 4 / Qt6 compatibility
• Refactor filter orchestrator, app, SQL utils and controllers
• Fix backward-compat guard for DEFAULT_IS_LINKING in exploring controller

Feature - GPKG Embedded Project Export

Exported GeoPackages now embed a full QGIS project that preserves layer group hierarchy, styles, and CRS. When opening the GPKG in QGIS, the embedded project automatically restores the original group structure.

New

• gpkg_layer_tree_writer.py: New module that embeds a QGIS project into exported GeoPackages using pure sqlite3 + xml.etree (safe for QGIS 3.44, no QgsProject lifecycle issues)
• Reads source project layer tree and reproduces group hierarchy in the embedded project
• Embeds layer styles (renderer, labeling, etc.) when "Save styles" is checked
• Uses export CRS when data is reprojected, preserving correct spatial reference
• Project stored as hex-encoded QGZ (ZIP) matching native QGIS GeoPackage project storage format

Bug Fix

• Fix action buttons not disabled when switching to exporting tab after filtering

Technical Details

The embedded project is built as XML, wrapped in QGZ (ZIP) format, hex-encoded, and inserted into the qgis_projects table — exactly matching how QGIS natively stores projects in GeoPackages. This ensures full compatibility with QGIS "Open Project from GeoPackage" workflow.

Bug Fix - GPKG Export Crash (Thread-Safety)

Symptom: QGIS crashes with "Windows fatal exception: access violation" when exporting to GPKG
Root Cause: iface.messageBar() was called from QgsTask background thread instead of main GUI thread

Changes

• layer_exporter.py: Remove iface.messageBar().pushSuccess() from export_to_gpkg() - success message now displayed by finished_handler on main thread
• layer_management_task.py: Add _deferred_warnings list to queue warnings for display in finished() callback
• layer_management_task.py: Move PostgreSQL PRIMARY KEY warning from run() to deferred display in finished()

Technical Details

Qt GUI operations are NOT thread-safe. Calling iface.messageBar() from a worker thread (QgsTask.run()) causes access violations on Windows. The fix defers all GUI operations to the finished() callback which runs on the main thread.

Bug Fix

• Fix key sidebar buttons appearing rectangular instead of square
• ButtonStyler._configure_pushbuttons() now excludes key sidebar buttons (exploring/filtering/exporting) whose Fixed/Fixed square sizing is managed by DimensionsManager
• Align exploring sidebar layout properties with filtering style (Expanding spacers, spacing=2)

Changes

• Website launch at https://imagodata.github.io/filter_mate/
• GitHub org migration: all URLs moved from sducournau to imagodata
• 600 unit tests across 34 files (quality score 9.0/10)
• Startup optimization for large GeoPackage projects (7 quick wins)
• filter_task.py reduced to 2,929 lines (-50.3%), 12 extracted handlers
• SignalBlocker context manager replaces all manual blockSignals
• CI/CD: GitHub Actions pytest (Python 3.10 + 3.12)
• i18n: 22 languages supported

• Version bump

Bug Fix - Buffer table creation fails on tables without id column

Symptom: Dynamic buffer expression like "largeur_de_chaussee" * 5 returns 1 = 0 (no features)
Root Cause: Buffer table creation SQL was hardcoded with "id" as source_id, failing on tables with different primary key names (e.g., cleabs, fid, ogc_fid)

Problem Analysis

When creating the pre-calculated buffer table for dynamic expressions:

-- v4.4.4 (BUG): Hardcoded "id" column
