struct mola::gui::ComboBox

Overview

A drop-down / combo-box (“pick one of N”).

items - display strings shown in the list. initial_index - zero-based index of the initially selected item. on_change - called with the new index from the GUI thread.

nanogui : nanogui::ComboBox; fixed_width (if > 0) via setFixedWidth(). ImGui : ImGui::Combo; fixed_width (if > 0) via SetNextItemWidth(), otherwise defaults to ImGui ‘s item width (which scales with the window, so long option labels grow the widget on resize).
