List of all members, including inherited members

Class Hierarchy¶

Base classes¶

Methods

`elevationFilterRangeSize`	Returns the fixed size for elevation range filtering in the project, used when interactively filtering by elevation.
`elevationRange`	Returns the project's elevation range, which indicates the upper and lower elevation limits associated with the project.
`invertElevationFilter`	Returns `True` if the elevation range filter slider should be inverted for this project.
`readXml`	Reads the property state from a DOM element.
`reset`	Resets the properties to a default state.
`resolveReferences`	Resolves reference to layers from stored layer ID.
`setElevationFilterRangeSize`	Sets the fixed size for elevation range filtering in the project, used when interactively filtering by elevation.
`setElevationRange`	Sets the project's elevation range, which indicates the upper and lower elevation limits associated with the project.
`setInvertElevationFilter`	Sets whether the elevation range filter slider should be inverted for this project.
`setTerrainProvider`	Sets the project's terrain provider.
`terrainProvider`	Returns the project's terrain provider.
`writeXml`	Returns a DOM element representing the properties.

Signals

`changed`	Emitted when the elevation properties change.
`elevationRangeChanged`	Emitted when the project's elevation is changed.

class qgis.core.QgsProjectElevationProperties[source]¶

Bases: QObject

__init__(parent: QObject | None = None)

Constructor for QgsProjectElevationProperties with the specified parent object.

Parameters:: parent (Optional[QObject] = None)

signal changed[source]¶: Emitted when the elevation properties change.

elevationFilterRangeSize(self) → float[source]¶

Returns the fixed size for elevation range filtering in the project, used when interactively filtering by elevation.

Returns -1 if no fixed elevation range size is desired.

A fixed size forces the selected elevation range to have a matching difference between the upper and lower elevation.

setElevationFilterRangeSize()

Added in version 3.38.

Return type:: float

elevationRange(self) → QgsDoubleRange[source]¶

Returns the project’s elevation range, which indicates the upper and lower elevation limits associated with the project.

Note

This is a manual, use-set property, and does not necessarily coincide with the elevation ranges for individual layers in the project.

See also

setElevationRange()

See also

elevationRangeChanged()

Added in version 3.38.

Return type:: QgsDoubleRange

signal elevationRangeChanged(range: QgsDoubleRange)[source]¶

Emitted when the project’s elevation is changed.

Note

This is a manual, use-set property, and does not necessarily coincide with the elevation ranges for individual layers in the project.

See also

elevationRange()

See also

setElevationRange()

Added in version 3.38.

Parameters:: range (QgsDoubleRange)

invertElevationFilter(self) → bool[source]¶

Returns True if the elevation range filter slider should be inverted for this project.

See also

setInvertElevationFilter()

Added in version 3.38.

Return type:: bool

readXml(self, element: QDomElement, context: QgsReadWriteContext) → bool[source]¶

Reads the property state from a DOM element.

See also

writeXml()

Parameters:

element (QDomElement)
context (QgsReadWriteContext)

Return type:

bool

reset(self)[source]¶: Resets the properties to a default state.

resolveReferences(self, project: QgsProject | None)[source]¶

Resolves reference to layers from stored layer ID.

Parameters:: project (Optional[QgsProject])

setElevationFilterRangeSize(self, size: float)[source]¶

Sets the fixed size for elevation range filtering in the project, used when interactively filtering by elevation.

Set to -1 if no fixed elevation range size is desired.

A fixed size forces the selected elevation range to have a matching difference between the upper and lower elevation.

See also

elevationFilterRangeSize()

Added in version 3.38.

Parameters:: size (float)

setElevationRange(self, range: QgsDoubleRange)[source]¶

Sets the project’s elevation range, which indicates the upper and lower elevation limits associated with the project.

Note

This is a manual, use-set property, and does not necessarily coincide with the elevation ranges for individual layers in the project.

See also

elevationRange()

See also

elevationRangeChanged()

Added in version 3.38.

Parameters:: range (QgsDoubleRange)

setInvertElevationFilter(self, invert: bool)[source]¶

Sets whether the elevation range filter slider should be inverted for this project.

See also

invertElevationFilter()

Added in version 3.38.

Parameters:: invert (bool)

setTerrainProvider(self, provider: QgsAbstractTerrainProvider | None)[source]¶

Sets the project’s terrain provider.

Ownership of provider is transferred to this object.

See also

terrainProvider()

Parameters:: provider (Optional[QgsAbstractTerrainProvider])

terrainProvider(self) → QgsAbstractTerrainProvider | None[source]¶

Returns the project’s terrain provider.

See also

setTerrainProvider()

Return type:: Optional[QgsAbstractTerrainProvider]

writeXml(self, document: QDomDocument, context: QgsReadWriteContext) → QDomElement[source]¶

Returns a DOM element representing the properties.

readXml()

Parameters:

document (QDomDocument)
context (QgsReadWriteContext)

Return type:

QDomElement
