Member Function Documentation

void NWidgetHorizontal::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 NWidgetHorizontalLTR.

void NWidgetHorizontal::SetupSmallestSize ( Window w,
bool  init_array 
) [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.

Parameters:
w Window owning the widget.
init_array Initialize the w->nested_array.
Note:
After the computation, the results can be queried by accessing the smallest_x and smallest_y data members of the widget.
