<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> </head> <body> Hi Hilaire, Recently i was studying the model thing. So one idea that comes to my mind is this. When the world gets clicked it does its usual stuff but also could emit a signal #worldWasLeftClicked. Your "modal" window or the little "pullDown" sons could have by default the running world as one of their model and then listen for the signal #worldWasLeftClicked. When they get it, they do harakiri. No idea if it is a good idea but it seems feasible. bye Nicola <div class="moz-cite-prefix">On 2/15/22 09:25, Hilaire Fernandes via Cuis-dev wrote: </div> <blockquote type="cite" cite="mid:f9f88099-bf54-df1c-0263-923ebb80fe4b@drgeo.eu"> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> Hi, In the screenshot below, observe the "Edit style' dialog. In its bottom there is a dropdown list of morphs (with a slider) representing type of mark to set to a segment. I need this dropdown morph to be modal: whenever the user click outside, this dropdown list must be deleted from the world. Any idea how to do it?
