Detailed Description

Base class for a resizable nested widget.

Definition at line 252 of file widget_type.h.

Constructor & Destructor Documentation

◆ NWidgetResizeBase()

NWidgetResizeBase::NWidgetResizeBase	(	WidgetType	tp,
		uint	fill_x,
		uint	fill_y
	)

Constructor for resizable nested widgets.

Parameters

tp	Nested widget type.
fill_x	Horizontal fill step size, `0` means no filling is allowed.
fill_y	Vertical fill step size, `0` means no filling is allowed.

Definition at line 846 of file widget.cpp.

References NWidgetBase::fill_x, and NWidgetBase::fill_y.

Member Function Documentation

◆ AssignSizePosition()

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

overridevirtual

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 NWidgetBackground.

Definition at line 922 of file widget.cpp.

◆ SetFill()

void NWidgetResizeBase::SetFill	(	uint	fill_x,
		uint	fill_y
	)

Set the filling of the widget from initial size.

Parameters

fill_x	Horizontal fill step size, `0` means no filling is allowed.
fill_y	Vertical fill step size, `0` means no filling is allowed.

Definition at line 905 of file widget.cpp.

◆ SetMinimalSize()

void NWidgetResizeBase::SetMinimalSize	(	uint	min_x,
		uint	min_y
	)

Set minimal size of the widget.

Parameters

min_x	Horizontal minimal size of the widget.
min_y	Vertical minimal size of the widget.

	)

Set minimal text lines for the widget.

Parameters

min_lines	Number of text lines of the widget.
spacing	Extra spacing (eg WD_FRAMERECT_TOP + _BOTTOM) of the widget.
size	Font size of text.

void NWidgetResizeBase::SetResize	(	uint	resize_x,
		uint	resize_y
	)

Set resize step of the widget.

Parameters
