I've come across two weird bugs (or at least strange effects) when using OpenWorldWithSpec. I'm not sure whether they are genuine bugs or it's just the way I've coded. I'm using the latest Pharo 3 on Ubuntu 13.10. I have a simple ComposableModel consisting of a TreeModel and a LabelModel which acts as a status line. The composableMorph is made up like this: spec <spec: #default> ^ SpecLayout composed add: #concordanceTreeModel origin: 0 @ 0 corner: 1 @ 1.0 offsetOrigin: 0 @ 0 offsetCorner: 0 @ self statusLineHeight negated; add: #statusLine origin: 0 @ 1.0 corner: 1.0 @ 1.0 offsetOrigin: 0 @ 0 offsetCorner: 0 @ self statusLineHeight negated; yourself When I run openInWorld I get the expected behaviour as below. <http://forum.world.st/file/n4735903/PharoScreenshot.2.png> Note how the background to the labelmodel status line is silver. But when I open the same ui with openWorldWithSpec I get this: <http://forum.world.st/file/n4735903/DarkGrayStatus.png> Note how the colour of the labelmodel background has changed. It's darker - in fact it has picked up the colour of my pharo desktop as though its background were transparent. Any ideas on this strange behaviour? Note also that the title of my ComposableModel is not copied to the pharo window either - this is bug 12231 which I reported a few weeks ago. The other strange effect is when I place the following code in a script |ui| ui := ConcordanceSpecUI new. ui openWorldWithSpec. and run it from the command line. This is what happens. <http://forum.world.st/file/n4735903/UsingStartupScript.png> (This is with an initialExtent specified - if there's no initial extent it's worse - I get a tiny area in the top left of the main window). But if I now click on the desktop, or resize the window, the interface suddenly corrects itself, like this: <http://forum.world.st/file/n4735903/good.png> I have tried this on Windows 7 and I do not get this behaviour - the ComposableModel fills the pharo window immediately and correctly. Any thoughts - should I be raising these as bugs? - Ken -- View this message in context: http://forum.world.st/Pharo-3-bugs-on-Linux-with-openWorldWithSpec-tp4735903...
