I added a new flag to the UiBuilder so that it is possible to move child widgets around the ui tree without losing state information. Currently there is no way to create child widgets with the same id at different locations in the ui tree since ids change in relation the the parent id. With the new flag a unique global scope can be created which always results in the same ids even at different locations. You still need to ensure that the widgets only get rendered once in frame. This feature can be used to fix a issue i am having with the https://github.com/lucasmerlin/hello_egui crate. * Closes lucasmerlin/hello_egui#75 * [X] I have followed the instructions in the PR template --------- Co-authored-by: Emil Ernerfeldt <[email protected]>
