# calcSize()

Recomputes any internal sizing information for the receiver, if necessary.

```
func calcSize()
```

## Discussion

This method uses the [`calcDrawInfo(_:)`](/documentation/AppKit/NSCell/calcDrawInfo(_:)) method of its cell to perform the calculations. Most controls maintain a flag that informs them if any of their cells have been modified in such a way that the location or size of the cell should be recomputed. If such a modification happens, this method is automatically invoked before the control is displayed. You should never need to invoke it yourself.

[`sizeToFit()`](/documentation/AppKit/NSControl/sizeToFit())

Resizes the receiver’s frame so that it’s the minimum size needed to contain its cell.
