Parametrul "Children Lock" este o valoare booleana, care se afla in toate straturile Paste Canvas. Acestea sunt straturile create atunci cand se encapsuleaza un grup de straturi.
Daca parametrul "Children Lock" este activat, atunci:
- La click pe un strat encapsulat din fereastra ......the workarea window, the Paste Canvas layer will be selected, rather than the layer you clicked on. For example, you draw an outline, and then encapsulate it. By default the children lock is off, and clicking on your outline in the workarea will select the outline layer. With children lock on, the encapsulation layer will be selected instead.
- Right-clicking on an encapsulation layer offers a context menu entry to 'Select All Child Layers', which recursively selects all the layers under the current layer. If the children lock is engaged for any encapsulation layer in the hierarchy, it stops the layers inside that encapsulation layer from being selected by this operation.
- Hitting control-a to select all the ducks in the currently selected layers will select the position ducks of child-locked encapsulation layers, whereas it won't when their children locks are off.
The effect of these three behaviors is for an encapsulation layer to act as if it was a primitive layer, hiding the details of its contents from selection or manipulation.
