Member Function Documentation

CalcMinimumSize()

Size open3d::visualization::gui::ListView::CalcMinimumSize ( const LayoutContext &  context ) const

overridevirtual

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

CalcPreferredSize()

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

overridevirtual

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

Draw()

Widget::DrawResult open3d::visualization::gui::ListView::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::visualization::gui::Widget.

GetSelectedIndex()

const

Returns the currently selected item in the list.

GetSelectedValue()

const char * open3d::visualization::gui::ListView::GetSelectedValue

(

)

num

)

Limit the max visible items shown to user. Set to negative number will make list extends vertically as much as possible, otherwise the list will at least show 3 items and at most show num items.

SetOnValueChanged()

void open3d::visualization::gui::ListView::SetOnValueChanged

(

std::function< void(const char *, bool)>

on_value_changed

)

Calls onValueChanged(const char *selectedText, bool isDoubleClick) when the list selection changes because of user action.

SetSelectedIndex()

void open3d::visualization::gui::ListView::SetSelectedIndex

(

int

index

)
