* Part of https://github.com/emilk/egui/issues/4535 * Closes https://github.com/emilk/egui/issues/3974 This adds a special `sizing_pass` mode to `Ui`, in which we have no centered or justified layouts, and everything is hidden. This is used by `Area` to use the first frame to measure the size of its contents so that it can then set the perfectly correct size the subsequent frames. For menus, where buttons are justified (span the full width), this finally the problem of auto-sizing. Before you would have to pick a width manually, and all buttons would expand to that width. If it was too wide, it looked weird. If it was too narrow, text would wrap. Now all menus are exactly the width they need to be. By default menus will wrap at `Spacing::menu_width`. This affects all situations when you have something that should be as small as possible, but still span the full width/height of the parent. For instance: the `egui::Separator` widget now checks the `ui.is_sizing_pass` flag before deciding on a size. In the sizing pass a horizontal separator is always 0 wide, and only in subsequent passes will it span the full width. |
