Widgets & Additional Functions

Once your project has been published, you can enhance your WebGIS service by enabling a variety of widgets and additional functions.


By clicking the Layers icon you can access the list of geographic layers that make up the project. From this interface, you can configure various functional options that will be enabled in the cartographic client.


The Data tab contains several columns, including:

Field Description
Label Alias set in the QGIS project
ID Unique identifier (eye icon) used for parameterized URLs
Name Layer name (file or DB table)
Type Data source type (WMS, PostGIS, GDAL, etc.)
WMS External Option to handle GetFeatureInfo responses outside QGIS Server
WFS Indicates if the layer is available as WFS


Note: WMS layers are handled directly by Django to speed up loading, bypassing QGIS Server.


Under the Actions column next to each layer, you’ll find a series of icons that allow you to manage its behavior and visibility:

Hint: Each action icon displays a number indicating how many related objects are configured.


The Download Capabilities column allows for the download of vector and raster data in the following formats:

Format Available For
SHP/GeoTIFF Vector and raster layers
GPKG All layers
XLS All layers
CSV All layers
GPX Geographic layers
PDF Attribute-level export for all


The Visibility Capabilities column allows you to configure general visibility options (applies to all users):

Option Effect
Hide Attributes Table Disables attribute table
Hide Legend Disables legend display
Hide Layer TOC Removes layer from TOC


Hint: Try enabling these features and test them directly in your WebGIS interface.

Creating a Search Widget

By default, search widgets can be configured on individual vector layers using the fields from the associated attribute table. Each search widget is saved by referencing the layer’s unique identifiers.

This design enables reusability: once a search widget is created for a specific layer, it becomes available in any other project where that same layer is used.


  1. From the Project List page, click the Layers icon next to the Tutorial_G3WSUITE project.

  2. The QGIS Project Layers section will open displaying all layers included in the published QGIS project.

  3. Next to the buildings layer, click the Widgets List icon.


  4. To create a new widget, click the Add New Widget button.

  5. In the Widget Creation Form, configure the following:

    • Type: Search
    • Name: Search Widget
    • Search Title: Tutorial Search Widget

  6. In the Search Field Settings section, set the following:

    • Field: type
    • Widget: SelectBox
    • Alias: Building Type
    • Operator: = (equal)


    Hint: Use the Add button to define multiple search conditions.

  7. Once finished, click OK to save.


The new search widget will now appear in the layer's widget list and will be automatically available in the WebGIS interface.

Creating a Plots Widget

The QPlotly widget enables users to view interactive plots, created using the DataPlotly QGIS plugin (developed by Matteo Ghetta), directly within the WebGIS cartographic client.

This module uses the Plotly library and supports plots saved as .xml files. Because each plot is linked to a specific layer in the QGIS project, it allows consistent reuse of the same plots across different WebGIS services, as long as the related layer is present.

Note: The plot title, defined in the DataPlotly plugin, acts as the unique identifier.


Plots can be filtered by:

  1. Map Extent: Based on visible features

  2. Feature Selection: Based on selected features


These filters also apply to related plots based on 1:N relationships. As users pan or zoom on the map, all related plots automatically update to reflect the visible extent.

If selection-based filtering is enabled, it is automatically applied to all linked plots associated with the same layer. Users will see clear messages on each chart indicating which filters are currently active.


When a layer has 1:N relationships with other tables that contain active plots, users can access those plots by querying the parent layer and clicking the Show Relation Charts icon. This feature enhances data exploration by allowing users to interact with and analyze related datasets directly within the WebGIS client.


  1. From the QGIS Project Layers list, next to the buildings layer, click the Qplotly Widgets icon.

  4. Navigate to Tutorial_Data_G3WSUITE -> plots and select: qplotly_type-distribution.


  5. Click Ok.
