However the size of the windows should change (to get larger) in some situation to at least fit all its contained morphs. Observe below. First picture, the contents changed but not the window extent, when dragging the window there are graphic artefacts. Second picture, when manually dragging a corner of the window, the window extent is adjusted automatically to its contents. Sure I could force it manually somewhere but I don't think it is right. The windows contents is changed with #replaceSubmorph:by: message in the breadcrumbs pane (horizontal collection of bottons and a view below) Thanks <pre class="moz-signature" cols="72">-- GNU Dr. Geo <a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://drgeo.eu">http://drgeo.eu</a> <a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://blog.drgeo.eu">http://blog.drgeo.eu</a></pre> </blockquote> Yes, SystemWindows don't #clipsSubmorphs and assume #submorphsMightProtrude is false. Therefore they can't be larger than contents. One obvious solution is to include a ScrollPane. But here you want the window to become larger to fit the submorphs. Please make an image where this is easily seen, so I can take a look.
