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 |
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. |
