| void | StoreSizePosition (SizingType sizing, uint x, uint y, uint given_width, uint given_height) |
| Store size and position. | |

| NWidgetResizeBase::NWidgetResizeBase | ( | WidgetType | tp, |
| uint | fill_x, | ||
| uint | fill_y | ||
| ) |
Constructor for resizable nested widgets.
| 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 806 of file widget.cpp.
References NWidgetBase::fill_x, and NWidgetBase::fill_y.
|
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.
