## Detailed Description

Order window code for all vehicles.

At the bottom of the window two button rows are located for changing the orders of the vehicle.

## Top row

The top-row is for manipulating an individual order. What row is displayed depends on the type of vehicle, and whether or not you are the owner of the vehicle.

The top-row buttons of one of your trains or road vehicles is one of the following three cases:

     * +-----------------+-----------------+-----------------+
     * |    NON-STOP     |    FULL_LOAD    |     UNLOAD      | (normal)
     * +-----------------+-----------------+-----------------+
     * |    COND_VAR     | COND_COMPARATOR |   COND_VALUE    | (for conditional orders)
     * +-----------------+-----------------+-----------------+
     * |    NON-STOP     |      REFIT      |     SERVICE     | (for depot orders)
     * +-----------------+-----------------+-----------------+
     *

Airplanes and ships have one of the following three top-row button rows:

     * +--------------------------+--------------------------+
     * |          FULL_LOAD       |          UNLOAD          | (normal)
     * +-----------------+--------+--------+-----------------+
     * |    COND_VAR     | COND_COMPARATOR |   COND_VALUE    | (for conditional orders)
     * +-----------------+--------+--------+-----------------+
     * |            REFIT         |          SERVICE         | (for depot order)
     * +--------------------------+--------------------------+
     *

## Bottom row

The second row (the bottom row) is for manipulating the list of orders:

     * +-----------------+-----------------+-----------------+
     * |      SKIP       |     DELETE      |      GOTO       |
     * +-----------------+-----------------+-----------------+
     *

For vehicles of other companies, both button rows are not displayed.

|  | Dimension * | size,
|  | const Dimension & | padding,
|  | Dimension * | fill,
|  | Dimension * | resize |
| ) |  |  | `[inline, virtual]`

Update size and resize step of a widget in the window.

After retrieval of the minimal size and the resize-steps of a widget, this function is called to allow further refinement, typically by computing the real maximal size of the content. Afterwards, size is taken to be the minimal size of the widget and resize is taken to contain the resize steps. For the convenience of the callee, padding contains the amount of padding between the content and the edge of the widget. This should be added to the returned size.

Parameters:

  | widget | Widget number.
  | size | Size of the widget.
  | padding | Recommended amount of space between the widget content and the widget edge.
  | fill | Fill step of the widget.
  | resize | Resize step of the widget.
