# dpg-map
|
|
|
|
`dpg-map` is a Dear PyGui map widget package under rebuild.
|
|
|
|
The Step 3 widget shell is in place:
|
|
|
|
```python
|
|
import dpg_map as dpgm
|
|
|
|
provider = dpgm.TileProvider(
|
|
name="custom",
|
|
url_template="https://example.com/{z}/{x}/{y}.png",
|
|
attribution="Tiles (c) Example",
|
|
)
|
|
dpgm.register_provider(provider)
|
|
|
|
with dpgm.map_widget(tag="map", center=(47.9029, 1.9093), zoom=15):
|
|
dpgm.add_marker("vehicle", lat=47.9029, lon=1.9093)
|
|
|
|
dpgm.update_marker("vehicle", lat=47.9030, lon=1.9094, map_tag="map")
|
|
```
|
|
|
|
Implemented so far:
|
|
|
|
- public package exports
|
|
- tile provider definitions and registry
|
|
- Web Mercator projection helpers
|
|
- thread-safe logical map state and map registry
|
|
- command queue with coalescing for overlay and view updates
|
|
- logical marker, polyline, trajectory, and layer models
|
|
- persistent disk cache path, metadata, scanning, and prune planning
|
|
- Dear PyGui `child_window` + measured-size `drawlist` widget shell
|
|
- GUI-thread frame pump that drains commands and redraws a placeholder background
|
|
- sizing helpers that preserve the last non-zero size across hidden layouts
|
|
- interaction hit-rectangle calculation for the measured map area
|
|
|
|
Real tile loading and overlay drawing are not implemented yet. Step 4 will add
|
|
the asynchronous tile manager, persistent tile loading, and GUI-thread texture
|
|
creation.
|
|
|
|
Examples:
|
|
|
|
```bash
|
|
uv run python examples/basic_map.py
|
|
uv run python examples/sizing_window.py
|
|
uv run python examples/sizing_child.py
|
|
uv run python examples/sizing_table.py
|
|
uv run python examples/hidden_tab.py
|
