* The controls are laid out as follows:
*
* -------------------------------------------
* | Directory input | execute |
* -------------------------------------------
* | Filename input | + | - | cancel |
* -------------------------------------------
*
* The input widgets will stretch to fill any excess space.
* When there isn't enough space for all controls to be shown, they are
* hidden in this order: x/-, execute/cancel, input widgets.
