Map styling

All style settings from QGIS are directly supported by QField.
This includes all renderer types like graduated, categorized, rule based,
2.5D as well as data defined symbology.

Display Expression

🖥️ Desktop preparation

In QField, objects are identified with a name.
The expression to generate this name can be defined by opening the attribute table in QGIS and switching to the form view.
Choose the appropriate field or an expression in the list there.
Starting from QGIS 3, this can be done directly from the Vector Layer Properties > Display page.

The display expression is also used to search in layers.

The display expression will be used to represent features with an identification string throughout QField.

Read only, non-identifiable and searchable layers

🖥️ Desktop preparation

Some layers in a project are just there for pure visual purpose.
Such layers should not show up when a user taps somewhere to identify
objects.

Some other layers serve as source of information and shouldn’t be
modified by the user.
It is possible to protect layers from editing attributes or adding and deleting features.

It is also possible to configure which layers are searchable.

To configure identify, read-only and searchable behavior, go to the
Project > Properties > Data Sources page and activate the checkboxes to match your desired behavior.

Using additional fonts

🖥️ Desktop preparation

QField enables you to use all the custom fonts you might want and need.
There are two different possibilities to register additional fonts:

  1. By adding fonts (.ttf or .otf) on the device in the folder <drive>:/Android/data/ch.opengis.qfield/files/QField/fonts.
    Those will be made accessible to all projects and individual datasets.
  2. By adding fonts (.ttf or .otf) in a fonts subfolder of the folder
    containing a given project file (.qgs or .qgz).
    Those fonts will only be accessible when viewing that project.

Custom SVG symbols

🖥️ Desktop preparation

It is possible to embed SVG symbols directly within a QGIS project.

  1. Choose the layer which will support SVG symbology and open its
    properties dialog.
  2. Open the section Symbology in Properties > Symbology
  3. In the Symbol Layer Panel choose Simple marker.
  4. Change the Symbol layer type in Symbol layer type > SVG marker.
  5. Scroll down the bottom panel.
  6. Click on the right side of the file selection button to open the
    drop down menu.
  7. Select Embed File and choose the SVG file in the file selection
    dialog.
  8. Apply the changes and click OK.
