Detailed Description

This is a vertical layout with a twisty + title that can be clicked on to expand or collapse the layout. Collapsing the layout will hide all the items and shrink the size of the layout to the height of the title.

Constructor & Destructor Documentation

◆ CollapsableVert() [1/2]

open3d::visualization::gui::CollapsableVert::CollapsableVert ( const char *  text)

◆ CollapsableVert() [2/2]

open3d::visualization::gui::CollapsableVert::CollapsableVert ( const char *  text,
int  spacing,
const Margins margins = Margins() 

◆ ~CollapsableVert()

open3d::visualization::gui::CollapsableVert::~CollapsableVert ( )

Member Function Documentation

◆ CalcPreferredSize()

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

◆ Draw()

Widget::DrawResult open3d::visualization::gui::CollapsableVert::Draw ( const DrawContext context)

Draws the widget. If this is a Dear ImGUI widget, this is where the actual event processing happens. Return NONE if no action needs to be taken, REDRAW if the widget needs to be redrawn (e.g. its value changed), and RELAYOUT if the widget wishes to change size.

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

◆ GetFontId()

FontId open3d::visualization::gui::CollapsableVert::GetFontId ( ) const

◆ GetIsOpen()

bool open3d::visualization::gui::CollapsableVert::GetIsOpen ( )

Returns true if open and false if collapsed.

◆ Layout()

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

◆ SetFontId()

void open3d::visualization::gui::CollapsableVert::SetFontId ( FontId  font_id)

◆ SetIsOpen()

void open3d::visualization::gui::CollapsableVert::SetIsOpen ( bool  is_open)

You will need to call Window::SetNeedsLayout() after this. (If you call this before the widnows is displayed everything will work out fine, as layout will automatically be called when the window is shown.)
