| 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, 0means no filling is allowed. | 
| fill_y | Vertical fill step size, 0means no filling is allowed. | 
Definition at line 805 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.
