This is different from other webkit based browsers thet currently clear with transparent black color. 151187 1 krit 2009-09-30 01:50:32 -0700 I can't open the original bug at nokia but it doesn't seem valid. A given rect is "filled" or better reseted to transparent black by: p->fillRect(rect, Qt::transparent); Qt::transparent is transparent black (http://doc.trolltech.com/4.4/qt.html#GlobalColor-enum). Can we close this bug? 151202 2 40354 krit 2009-09-30 02:52:26 -0700 Created attachment 40354 clearRect This example shows the use of clearRect. If clearRect works like expacted, you should see a green page and a black border at the top left. This rect schould be filled with green (transparent black of the clearRect). This example works for me on QtLauncher. I close this bug for now. Please reopen the bug if you have another example, that doesn't work. 40354 2009-09-30 02:52:26 -0700 2009-09-30 02:52:26 -0700 clearRect index.html text/html 376 krit PGh0bWw+CjxoZWFkPgo8c2NyaXB0IHR5cGU9ImFwcGxpY2F0aW9uL3gtamF2YXNjcmlwdCI+CiAg ZnVuY3Rpb24gZHJhdygpewogICAgICB2YXIgY3R4ID0gZG9jdW1lbnQuZ2V0RWxlbWVudEJ5SWQo J2NhbnZhcycpLmdldENvbnRleHQoJzJkJyk7CgogICAgICAvLyBkcmF3IHJlY3RhbmdsZQogICAg ICBjdHguZmlsbFJlY3QoMCwwLDEwMCwxMDApOwogICAgICBjdHguY2xlYXJSZWN0KDI1LDI1LDUw LDUwKTsKICB9Cjwvc2NyaXB0Pgo8L2hlYWQ+Cjxib2R5IHN0eWxlPSJiYWNrZ3JvdW5kOmdyZWVu OyIgb25sb2FkPSJkcmF3KCk7Ij4KPGNhbnZhcyBpZD0iY2FudmFzIiB3aWR0aD0iMTAwIiBoZWln aHQ9IjEwMCI+PC9jYW52YXM+CjwvYm9keT48L2h0bWw+Cg==
