Selection is not a simple concept because there are different types of selection.
The workbench selection is determined by what is selected in the current view. For example in the Layers view the selection will always be a layer. In the Project Explorer the selection could be a project, map, page, etc... The selection in the Map Editor depends on the tool that is selected.
Tool | Selection |
---|---|
Zoom | The map shown in the map editor |
Pan | The map shown in the map editor |
Selection | The current layer's selection filter |
Information Tools | The map shown in the map editor |
Edit Tools | The currently edited feature or the currently selected vertices. Depending on whether there are selected vertices |
Each layer has a filter that indicates what is selected on that layer.
The EditBlackboard contains the features that have been selected for editing. At any one time a single feature on the edit blackboard is the edit feature, the feature that has the vertex handles and can directly be edited.
