The editor view is started when a layer preset is created or changed. Among other things, the Map Layers view is available.
In this view, you can define the map layers to be taken into account, as well as their visibility. If a new layer preset has been created, it is automatically filled with the 1:1 image of the table of contents (TOC).
The visibility of the map layers can be influenced or created in various ways:
By clicking on this function, the current status of the TOC is overtaken 1:1. All map layers that have visibility are used. Group layers are also overtaken. However, the information on the current query (query definition) is missing for these layers.
The map layers are given an ID in the layer presets so that the properties can be written back to the map layers. This ID corresponds to the layer path. The layer path is formed from the names of all layers that have a hierarchical dependency. A map layer that is displayed directly below the map is given its own name as an ID. If a map layer is within a group layer, the name of the group is prefixed and separated with @: {Group name}@{Layername} (e.g., Points@Gas Points)

It is therefore possible for a layer ID to be derived twice in the same way if several layers contain the same name and also the same group names. This fact is displayed in the list of map layers when displaying/editing a layer preset:
In the tooltip that appears on the layer node, it is pointed out again that the map layers with the same ID are changed together and not individually. If different properties are to be assigned to the layers, the names of these, or the groups in which they are to be found, must be adapted so that the ID is unique.
Here is an example of how map layers can have the same ID:
Map layers in the TOC can be selected. The two following functions take the selected map layers into account.
1.Selection Takeover
When this function is executed, only the selected map layers of the TOC are overtaken. All other map layers are ignored.
If the superordinate group layer of a map layer has not also been selected, the group is only displayed schematically in the map layer tree. If this layer presets is used, all map layers that are not listed here will not be changed in the TOC.
2.Inverted Selection Takeover
Here, the selected map layers in the TOC are excluded from the transfer, so that only the map layers that are not currently selected are changed when this function is used.
If the superordinate group layer of a map layer has not also been selected, the group is only displayed schematically in the map layer tree. If this layer presets is used, all map layers that are not listed here will not be changed in the TOC.
If map layers already exist, the visibility of the layers can be defined directly by ticking the box in front of them.
Enable the check-box, to make all listed map layers visible. If the check-box is disabled, all map layers are invisible.
