Detailed Description

Custom nested widget container for the NewGRF gui.

Depending on the space in the gui, it uses either

two column mode, put the acs and the avs underneath each other and the inf next to it, or
three column mode, put the avs, acs, and inf each in its own column.

Member Function Documentation

◆ AssignSizePosition()

void NWidgetNewGRFDisplay::AssignSizePosition	(	SizingType	sizing,
		int	x,
		int	y,
		uint	given_width,
		uint	given_height,
		bool	rtl
	)

inlineoverridevirtual

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.

Definition at line 1666 of file newgrf_gui.cpp.

◆ Draw()

void NWidgetNewGRFDisplay::Draw ( const Window * w )

inlineoverridevirtual

Draw the widgets of the tree. The function calls Window::DrawWidget for each widget with a non-negative index, after the widget itself is painted.

Parameters

w	Window that owns the tree.

Implements NWidgetBase.

Definition at line 1802 of file newgrf_gui.cpp.

◆ FillWidgetLookup()

void NWidgetNewGRFDisplay::FillWidgetLookup ( WidgetLookup & widget_lookup )

inlineoverridevirtual

Fill the Window::widget_lookup with pointers to nested widgets in the tree.

Parameters

widget_lookup The WidgetLookup.

Implements NWidgetBase.

Definition at line 1785 of file newgrf_gui.cpp.

◆ GetWidgetFromPos()

NWidgetCore* NWidgetNewGRFDisplay::GetWidgetFromPos	(	int	x,
		int	y
	)

inlineoverridevirtual

Retrieve a widget by its position.

Parameters

x	Horizontal position relative to the left edge of the window.
y	Vertical position relative to the top edge of the window.

Returns: Returns the deepest nested widget that covers the given position, or nullptr if no widget can be found.

Implements NWidgetBase.

Definition at line 1792 of file newgrf_gui.cpp.

◆ SetupSmallestSize()

void NWidgetNewGRFDisplay::SetupSmallestSize ( Window * w )

inlineoverridevirtual

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.

Note: After the computation, the results can be queried by accessing the smallest_x and smallest_y data members of the widget.

Implements NWidgetBase.

Definition at line 1623 of file newgrf_gui.cpp.
