Data Fields inherited from NWidgetBase | |
WidgetType | type |
Type of the widget / nested widget. | |
uint | fill_x |
Horizontal fill stepsize (from initial size, 0 means not resizable). | |
uint | fill_y |
Vertical fill stepsize (from initial size, 0 means not resizable). | |
uint | resize_x |
Horizontal resize step (0 means not resizable). | |
uint | resize_y |
Vertical resize step (0 means not resizable). | |
uint | smallest_x |
Smallest horizontal size of the widget in a filled window. | |
uint | smallest_y |
Smallest vertical size of the widget in a filled window. | |
uint | current_x |
Current horizontal size (after resizing). | |
uint | current_y |
Current vertical size (after resizing). | |
float | aspect_ratio = 0 |
Desired aspect ratio of widget. | |
AspectFlags | aspect_flags = AspectFlags::ResizeX |

int | pos_x |
Horizontal position of top-left corner of the widget in the window. | |
int | pos_y |

RectPadding | padding |
Padding added to the widget. Managed by parent container widget. (parent container may swap left and right for RTL) | |
RectPadding | uz_padding |
Unscaled padding, for resize calculation. | |

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.
Definition at line 1909 of file smallmap_gui.cpp.
|
inlineoverridevirtual |
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.
Implements NWidgetBase.

|
inlineoverridevirtual |
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. |
Implements NWidgetBase.
