Member Function Documentation

◆ AddItem()

int open3d::visualization::gui::Combobox::AddItem ( const char * name )

Adds an item to the combobox. Its index is the order in which it is added, so the first item's index is 0, the second is 1, etc. Returns the index of the new item.

◆ CalcPreferredSize()

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

overridevirtual

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

◆ ChangeItem() [1/2]

void open3d::visualization::gui::Combobox::ChangeItem	(	const char *	orig_name,
		const char *	new_name
	)

If an item exists with orig_name, it will be changed to new_name.

◆ ChangeItem() [2/2]

void open3d::visualization::gui::Combobox::ChangeItem	(	int	index,
		const char *	name
	)

Changes the item's text. index must be valid, otherwise nothing will happen.

◆ ClearItems()

void open3d::visualization::gui::Combobox::ClearItems ( )

◆ Draw()

Combobox::DrawResult open3d::visualization::gui::Combobox::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.

◆ GetItem()

const char * open3d::visualization::gui::Combobox::GetItem ( int index ) const

Returns the text of the item at index. index must be valid.

◆ GetNumberOfItems()

int open3d::visualization::gui::Combobox::GetNumberOfItems ( ) const

◆ GetSelectedIndex()

int open3d::visualization::gui::Combobox::GetSelectedIndex ( ) const

◆ GetSelectedValue()

const char * open3d::visualization::gui::Combobox::GetSelectedValue ( ) const

Returns the text of the selected value, or "" if nothing is selected.

◆ RemoveItem() [1/2]

void open3d::visualization::gui::Combobox::RemoveItem ( const char * name )

Removes the first item matching the given text.

◆ RemoveItem() [2/2]

void open3d::visualization::gui::Combobox::RemoveItem ( int index )

Removes the item at index.

◆ SetOnValueChanged()

void open3d::visualization::gui::Combobox::SetOnValueChanged ( std::function< void(const char *, int)> on_value_changed )

Specifies a callback function which will be called when the value changes as a result of user action.

◆ SetSelectedIndex()

void open3d::visualization::gui::Combobox::SetSelectedIndex ( int index )

Sets the selected item by index. Does not call the onValueChanged callback.
