Detailed Description

Lays out widgets either horizontally or vertically. Base class for Vert and Horiz.

Constructor & Destructor Documentation

Layout1D()

open3d::visualization::gui::Layout1D::Layout1D	(	Dir	dir,
		int	spacing,
		const Margins &	margins,
		const std::vector< std::shared_ptr< Widget >> &	children
	)

Spacing is in pixels; see the comment in Margin(). 1em is typically a good value for spacing.

Member Function Documentation

AddFixed()

void open3d::visualization::gui::Layout1D::AddFixed

(

int

size

)

Adds a fixed number of pixels after the previously added widget.

AddStretch()

void open3d::visualization::gui::Layout1D::AddStretch

(

)

Adds a virtual widget that takes up as much space as possible. This is useful for centering widgets: { stretch, w1, w2, stretch } or for aligning widgets to one side or the other: { stretch, ok, cancel }.

CalcPreferredSize()

Size open3d::visualization::gui::Layout1D::CalcPreferredSize ( const LayoutContext &  context, const Constraints &  constraints  ) const

overridevirtual

Reimplemented from open3d::visualization::gui::Widget.

Reimplemented in open3d::visualization::gui::CollapsableVert.

debug_PrintPreferredSizes()

void open3d::visualization::gui::Layout1D::debug_PrintPreferredSizes ( Layout1D *  layout, const LayoutContext &  context, const Constraints &  constraints, int  depth = 0  )

static

GetMargins()

const Margins & open3d::visualization::gui::Layout1D::GetMargins

(

)

const

GetMinorAxisPreferredSize()

int open3d::visualization::gui::Layout1D::GetMinorAxisPreferredSize ( ) const

protected

GetMutableMargins()

Margins & open3d::visualization::gui::Layout1D::GetMutableMargins ( )

protected

GetSpacing()

int open3d::visualization::gui::Layout1D::GetSpacing

(

)

const

GetVisibleChildren()

std::vector< std::shared_ptr< Widget > > open3d::visualization::gui::Layout1D::GetVisibleChildren ( ) const

protected

Layout()

void open3d::visualization::gui::Layout1D::Layout ( const LayoutContext &  context )

overridevirtual

Reimplemented from open3d::visualization::gui::Widget.

Reimplemented in open3d::visualization::gui::CollapsableVert.

SetMargins()

void open3d::visualization::gui::Layout1D::SetMargins

(

const Margins &

margins

)

Sets margins. Need to signal a relayout after calling (unless it is before a layout that will happen, such as before adding as a child).

SetMinorAxisPreferredSize()

void open3d::visualization::gui::Layout1D::SetMinorAxisPreferredSize ( int  size )

protected

SetSpacing()

void open3d::visualization::gui::Layout1D::SetSpacing

(

int

spacing

)

Sets spacing. Need to signal a relayout after calling (unless it is before a layout that will happen, such as before adding as a child).
