Member Function Documentation

◆ AddItem()

TreeView::ItemId open3d::visualization::gui::TreeView::AddItem ( ItemId  parent_id,
std::shared_ptr< Widget >  item 
)

Adds an item to the tree.

◆ AddTextItem()

TreeView::ItemId open3d::visualization::gui::TreeView::AddTextItem ( ItemId  parent_id,
const char *  text 
)

Adds a text item to the tree.

◆ CalcMinimumSize()

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

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

◆ CalcPreferredSize()

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

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

◆ Clear()

void open3d::visualization::gui::TreeView::Clear ( )

Clears all the items.

◆ Draw()

Widget::DrawResult open3d::visualization::gui::TreeView::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.

◆ GetCanSelectItemsWithChildren()

bool open3d::visualization::gui::TreeView::GetCanSelectItemsWithChildren ( ) const

◆ GetItem()

std::shared_ptr< Widget > open3d::visualization::gui::TreeView::GetItem ( ItemId  item_id) const

Returns item, or nullptr if item_id cannot be found.

◆ GetItemChildren()

std::vector< TreeView::ItemId > open3d::visualization::gui::TreeView::GetItemChildren ( ItemId  parent_id) const

◆ GetRootItem()

TreeView::ItemId open3d::visualization::gui::TreeView::GetRootItem ( ) const

Returns the ID of the root item, that is, AddItem(GetRootItem(), ...) will be a top-level item.

◆ GetSelectedItemId()

TreeView::ItemId open3d::visualization::gui::TreeView::GetSelectedItemId ( ) const

Returns the currently selected item id in the tree.

◆ Layout()

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

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

◆ RemoveItem()

void open3d::visualization::gui::TreeView::RemoveItem ( ItemId  item_id)

Removes an item an all its children (if any) from the tree.

◆ SetCanSelectItemsWithChildren()

void open3d::visualization::gui::TreeView::SetCanSelectItemsWithChildren ( bool  can_select)

If true, enables selecting items that have children. Items can be toggled open/closed with the triangles or by double-clicking. Default is false.

◆ SetOnSelectionChanged()

void open3d::visualization::gui::TreeView::SetOnSelectionChanged ( std::function< void(ItemId)>  on_selection_changed)

Calls onSelectionChanged(const char *sel_text, ItemId sel_item_id) when the list selection changes because of user action.

◆ SetSelectedItemId()

void open3d::visualization::gui::TreeView::SetSelectedItemId ( ItemId  item_id)

Selects the indicated item of the list. Does not call onValueChanged.
