Custom container class for displaying smallmap with a vertically resizing legend panel.
The legend panel has a smallest height that depends on its width. Standard containers cannot handle this case.

virtual void NWidgetSmallmapDisplay::AssignSizePosition | ( | SizingType | sizing, | |
uint | x, | |||
uint | y, | |||
uint | given_width, | |||
uint | given_height, | |||
bool | rtl | |||
) | [inline, virtual] |
Assign size and position to the widget.
sizing | Type of resizing to perform. | |
x | Horizontal offset of the widget relative to the left edge of the window. | |
y | Vertical offset of the widget relative to the top edge of the window. | |
given_width | Width allocated to the widget. | |
given_height | Height allocated to the widget. | |
rtl | Adapt for right-to-left languages (position contents of horizontal containers backwards). |
Afterwards, pos_x and pos_y contain the top-left position of the widget, smallest_x and smallest_y contain the smallest size such that all widgets of the window are consistent, and current_x and current_y contain the current size.

virtual void NWidgetSmallmapDisplay::Draw | ( | const Window * | w | ) | [inline, virtual] |
Draw the widgets of the tree.
The function calls Window::DrawWidget for each widget with a non-negative index, after the widget itself is painted.
w | Window that owns the tree. |

virtual NWidgetCore* NWidgetSmallmapDisplay::GetWidgetFromPos | ( | int | x, | |
int | y | |||
) | [inline, virtual] |
Retrieve a widget by its position.
x | Horizontal position relative to the left edge of the window. | |
y | Vertical position relative to the top edge of the window. |
NULL
if no widget can be found. Implements NWidgetBase.

virtual void NWidgetSmallmapDisplay::SetupSmallestSize | ( | Window * | w, | |
bool | init_array | |||
) | [inline, virtual] |
Compute smallest size needed by the widget.
The smallest size of a widget is the smallest size that a widget needs to display itself properly. In addition, filling and resizing of the widget are computed. The function calls Window::UpdateWidgetSize for each leaf widget and background widget without child with a non-negative index.
w | Window owning the widget. | |
init_array | Initialize the w->nested_array . |
