![]() | |
void | StoreSizePosition (SizingType sizing, uint x, uint y, uint given_width, uint given_height) |
Store size and position. |
Matrix container with implicitly equal sized (virtual) sub-widgets.
This widget must have exactly one sub-widget. After that this sub-widget is used to draw all of the data within the matrix piece by piece. DrawWidget and OnClick calls will be done to that sub-widget, where the 16 high bits are used to encode the index into the matrix.

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 . |
