From 80ffc2fa1766aa8009a30de495fc11ab6690bd87 Mon Sep 17 00:00:00 2001 From: "Eduardo M. Fleury" Date: Thu, 8 Oct 2009 14:30:57 -0300 Subject: QGraphicsAnchorLayout: Add test for 'infinite' max size widgets With four items anchored side by side, each of them being allowed to grow to QWIDGETSIZE_MAX, we have a situation of fair distribution because the layout itself can grow only to QWIDGETSIZE_MAX (and not four times this amount). This test identified an error on the expanding distribution logic. Signed-off-by: Eduardo M.
