## Function Documentation

static void CommonRaiseLowerBigLand | ( | TileIndex | tile,
|  | int | mode |
| ) |  |  | `[static]`

Raise/Lower a bigger chunk of land at the same time in the editor.

When raising get the lowest point, when lowering the highest point, and set all tiles in the selection to that height.

Todo:
  : Incorporate into game itself to allow for ingame raising/lowering of larger chunks at the same time OR remove altogether, as we have 'level land' ?

Parameters:

  | tile | The top-left tile where the terraforming will start
  | mode | 1 for raising, 0 for lowering land

static void EditorTerraformClick_Dynamite | ( | Window * | w | ) | `[static]`

Todo:
  Merge with terraform_gui.cpp (move there) after I have cooled down at its braindeadness and changed OnButtonClick to include the widget as well in the function declaration. Post 0.4.0 - Darkvater

bool GUIPlaceProcDragXY | ( | ViewportDragDropSelectionProcess | proc,
|  | TileIndex | start_tile,
|  | TileIndex | end_tile |
| ) |  |  |

A central place to handle all X_AND_Y dragged GUI functions.

Parameters:

  | proc | Procedure related to the dragging
  | start_tile | Begin of the dragging
  | end_tile | End of the dragging

Returns:
  Returns true if the action was found and handled, and false otherwise. This allows for additional implements that are more local. For example X_Y drag of convertrail which belongs in rail_gui.cpp and not terraform_gui.cpp

static void ResetLandscapeConfirmationCallback | ( | Window * | w,
|  | bool | confirmed |

Parameters:
