* Closes #686 * Closes #839 * #5370 should be merged before this * [x] I have followed the instructions in the PR template This adds modals to egui. This PR - adds a new `Modal` struct - adds `Memory::set_modal_layer` to limit focus to a layer and above (used by the modal struct, but could also be used by custom modal implementations) - adds `Memory::allows_interaction` to check if a layer is behind a modal layer, deprecating `Layer::allows_interaction` Current problems: - ~When a button is focused before the modal opens, it stays focused and you also can't hit tab to focus the next widget. Seems like focus is "stuck" on that widget until you hit escape. This might be related to https://github.com/emilk/egui/issues/5359~ fixed! Possible future improvements: - The titlebar from `window` should be made into a separate widget and added to the modal - The state whether the modal is open should be stored in egui (optionally), similar to popup and menu. Ideally before this we would refactor popup state to unify popup and menu --------- Co-authored-by: Emil Ernerfeldt <emil.ernerfeldt@gmail.com> |
