## Constructor & Destructor Documentation

NWidgetResizeBase::NWidgetResizeBase | ( | WidgetType | tp,
|  | uint | fill_x,
|  | uint | fill_y |
| ) |  |  |

Constructor for resizable nested widgets.

Parameters:

  | tp | Nested widget type.
  | fill_x | Horizontal fill step size, `0` means no filling is allowed.
  | fill_y | Vertical fill step size, `0` means no filling is allowed.

Definition at line 716 of file widget.cpp.

## Member Function Documentation

void NWidgetResizeBase::AssignSizePosition | ( | SizingType | sizing,
|  | uint | x,
|  | uint | y,
|  | uint | given_width,
|  | uint | given_height,
|  | bool | rtl |
| ) |  |  | `[virtual]`

Assign size and position to the widget.

Parameters:

  | 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.

Reimplemented in NWidgetBackground.

void NWidgetResizeBase::SetMinimalTextLines | ( | uint8 | min_lines,
|  | uint8 | spacing,
|  | FontSize | size |
| ) |  |  |

Set minimal text lines for the widget.

Parameters:

  | min_lines | Number of text lines of the widget.
  | spacing | Extra spacing (eg WD_FRAMERECT_TOP + _BOTTOM) of the widget.
  | size | Font size of text.

void NWidgetResizeBase::SetResize | ( | uint | resize_x,
|  | uint | resize_y |
| ) |  |  |

Set resize step of the widget.

Parameters:

  | resize_x | Resize step in horizontal direction, value `0` means no resize, otherwise the step size in pixels.
  | resize_y | Resize step in vertical direction, value `0` means no resize, otherwise the step size in pixels.
