## Detailed Description

Handling of the main viewport.

Definition in file main_gui.cpp.

## Enumeration Type Documentation

enum MainWindowWidgets

Widgets of the main window.

Enumerator:

  MW_VIEWPORT | Main window viewport.

Definition at line 192 of file main_gui.cpp.

## Function Documentation

void GameSizeChanged | ( |  | ) |

Size of the application screen changed.

Adapt the game screen-size, re-allocate the open windows, and repaint everything

Definition at line 439 of file main_gui.cpp.

bool HandlePlacePushButton | ( | Window * | w,
|  | int | widget,
|  | CursorID | cursor,
|  | HighLightStyle | mode,
|  | PlaceProc * | placeproc |
| ) |  |  |

This code is shared for the majority of the pushbuttons.

Handles e.g. the pressing of a button (to build things), playing of click sound and sets certain parameters

Parameters:

  | w | Window which called the function
  | widget | ID of the widget (=button) that called this function
  | cursor | How should the cursor image change? E.g. cursor with depot image in it
  | mode | Tile highlighting mode, e.g. drawing a rectangle or a dot on the ground
  | placeproc | Procedure which will be called when someone clicks on the map

Returns:
  true if the button is clicked, false if it's unclicked
