Graph IDE ► Inspector Editors ► Layer
A Layer is a collection of independent graphics and is described in the Layer section.
Some standard operations are itemized below.
Note that graphics in a layer are individually editable and selectable and operate independently. Contrast that to a Group graphic which is a container for graphics that are not independent.
The Bounds Editor for a Layer is shown below.
Table controls are described in the Tables section.
The rows represent the bounds of graphics in the layer. Those bounds can be edited directly or via any of the individual graphic's Graphics inspector editor.
The Graphics Editor for a Layer is shown below.
Edit : The Edit menu shortcut is one of Cut, Copy, Paste, Delete or Select All.
Align : The align menu is used to align graphics in the layer.
History : Shows the history of the layer. For this to be enabled, history recording must be selected in the Graphic View tool inspector. Selecting a menu item makes that history recording the current state. On platforms that accept hover, hovering over a menu item will pan the history. The last menu item clears the history only for the focused layer. All history can also be cleared in the Graphic View tool inspector.
Selection : Determines which grouping in the layer is to be edited by the inspector. Normally this is kept to Selection indicating that only selected graphics are to be altered. However, it could also be any of the other options such as Draw indicating that any drawable graphic is to be altered.
Identity : Defines the identity string of the layer. The identity helps determine the current overlay as well as describes the intended use of the overlay or layer. It is displayed by the Navigator, Cursor Information and the data layers for Graphs.
Group Selection : Removes the selected graphics from the layer and then places those selected graphics into a Group graphic which is then added to the layer. When this happens the focus is transferred to the group. From there, the group can be ungrouped if needed thus reversing this operation.
Other controls common to all graphics are described in the Graphics section.
When altering a graphic attribute that attribute is applied to each element in the layer independently. Notice how if the graphics are rotated then they are rotated individually with the fulcrums at the center of each individual graphic. Contrast that to the way a Group rotates its graphics which rotates around a common fulcrum point which is the center of the group as a whole.
