# calcSize()

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

## Declaration

```swift
func calcSize()
```

## Discussion

Discussion This method uses the 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.
