    Detailed Description

    KML is a file format used to display geographic data (geometric shapes, symbology and attributes). KML uses a tag-based structure with nested elements and attributes and is based on the XML standard. The KML files are often distributed in KMZ files, which are zipped KML files with a .kmz extension.

    Member Function Documentation

    QString KmlNode::address() const

    Returns the address of the KML node.

    Represents an unstructured address such as a street, city, state address, and/or a postal code.

    This function was introduced in Esri::ArcGISRuntime 100.7.

    See also setAddress().

    Returns the balloon content that should be displayed in a balloon popup for the KML node.

    QString KmlNode::description() const

    Returns the description of the KML node.

    See also setDescription().

    Esri::ArcGISRuntime::Envelope KmlNode::extent() const

    Returns the extent for the KML node.

    Esri::ArcGISRuntime::KmlStyle *KmlNode::highlightStyle()

    The KML node's highlight style. This style is used when the KML node has been highlighted / selected.

    See also setHighlightStyle().

    bool KmlNode::isHighlighted() const

    Returns a flag indicating if the KML node is highlighted.

    bool KmlNode::isVisible() const

    Returns a flag indicating if the KML node is visible.

    QString KmlNode::kmlNodeId() const

    Returns the kmlNodeId of the KML node.

    The kmlNodeId is a standard XML ID and can be empty.

    This function was introduced in Esri::ArcGISRuntime 100.6.

    See also setKmlNodeId().

    Esri::ArcGISRuntime::KmlNodeType KmlNode::kmlNodeType() const

    Returns the KmlNodeType of this KML Node object.

    QString KmlNode::name() const

    Returns the name of the KML node.

    See also setName().

    Esri::ArcGISRuntime::KmlNode *KmlNode::parentNode() const

    Returns the KML node's parent.

    Esri::ArcGISRuntime::Error KmlNode::refreshError() const

    Returns the KML node's refresh error.

    Esri::ArcGISRuntime::KmlRefreshStatus KmlNode::refreshStatus() const

    Returns the KML node's refresh status.

    Use the node refresh status to update the node's properties and update application UI.

    • KmlRefreshStatus::None - No action required.
    • KmlRefreshStatus::InProgress - Invalidate the node and its children. Application may show an appropriate UI cue such as a spinning wheel on top of the node's TOC icon to indicate in-progress status and to restrict user interaction with the node.
    • KmlRefreshStatus::Completed - Read and update the node's properties and its children.
    • KmlRefreshStatus::Error - Application may call refreshError to get the reason for failure and show the error message. Also, applications may show an appropriate UI cue such as a red X with the node's TOC icon to indicate the failed status.

    See also refreshError.

    Esri::ArcGISRuntime::TaskWatcher KmlNode::saveAs(const QString &kmzFile) const

    Saves the node and any referenced local files into a zipped KMZ archive at local file path specified in kmzFile.

    The node is saved to a KMZ file to ensure that any referenced files are available locally when sharing the KMZ file with others.

    • When this method is called on a leaf node (e.g. KmlPlacemark, KmlGroundOverlay, and so on), only that node and its referenced files are saved.
    • When this method is called on a container node (e.g. KmlDocument, KmlFolder), the node and all of its children and referenced files are saved.
    • When this method is called on a KmlNetworkLink, the link is saved but the children are not. This is because the children will be refetched when the saved KmlNetworkLink is loaded.

    Saving referenced files will differ based on the type of path used for reference.

    • For HTTP paths, the path is saved as-is but the referenced file is not zipped into the archive, as it will be refetched when the new KMZ file is loaded.
    • For relative paths, the path is saved as-is and the referenced file is zipped relative to the root of the KMZ file.
    • For absolute paths, the path is converted to a relative path, and the referenced file is zipped into a "files" folder at the root of the KMZ file. For example, C:/icons/some_icon.png is converted to files/some_icon.png and stored at that location in the KMZ file.

    The filename supports Unicode characters as well as nested directories

    The saveAsCompleted signal is fired when a saveAs operation completes.

    This function was introduced in Esri::ArcGISRuntime 100.6.
