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.

Member Function Documentation

CalcPreferredSize()

Size open3d::gui::CollapsableVert::CalcPreferredSize ( const Theme &  theme ) const

overridevirtual

Reimplemented from open3d::gui::Layout1D.

Draw()

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

overridevirtual

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::gui::Widget.

Layout()

void open3d::gui::CollapsableVert::Layout ( const Theme &  theme )

overridevirtual

Reimplemented from open3d::gui::Layout1D.

SetIsOpen()

void open3d::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.)
