The align result is taken into account if present
- Parameters
-
item The item to display
| - (unsigned int) getModifiers |
Get the modifiers associated with the selection.
- Returns
- The modifiers of the current selection
| - (LynkeosIntegerRect) getSelection |
Retrieve the current selection.
- Returns
- The current selection rectangle
| - (LynkeosIntegerRect) getSelectionAtIndex: | (u_short) | index |

- Parameters
-
index The index of the selection to retrieve
- Returns
- The current selection rectangle

| atIndex: | (u_short) | index | |
| resizable: | (BOOL) | resize | |
| movable: | (BOOL) | move | |
Set a given selection rectangle.
The first unused index shall be used to create a new selection.
- Parameters
-
selection The new selection rectangle. index The index of the selection resize Is this new selection resizable. move Whether the selection can be moved
| - (void) setSelection: | (LynkeosIntegerRect) | selection | |
| resizable: | (BOOL) | resize | |
| movable: | (BOOL) | move | |
Set the selection rectangle.
For compatibility reasons, all indexed selections are removed
- Parameters
-
selection The new current selection rectangle. resize Is this new selection resizable. move Whether the selection can be moved
