◆ 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

◆ debug_PrintPreferredSizes()

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

◆ GetMargins()

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

◆ GetMinorAxisPreferredSize()

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

◆ GetMutableMargins()

◆ GetSpacing()

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

◆ GetVisibleChildren()

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

◆ Layout()

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

◆ 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)

◆ 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).
