From a8e5abd7b8f24c6fdb4b981da36c8c7c0bc2f8c2 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Sami=20Meril=C3=A4?= Date: Tue, 17 Nov 2009 13:02:42 +0200 Subject: LineEdit graphics are sometimes missing from webpages with s60style If the webpage does define BODY colors for background, it is possible that lineEdits are not drawn at all. Actually, they are drawn but with transparent background, which makes them near-invisible. This is due to that QS60Style tries to check if the themePalette has been changed and if it has forwards the drawing of that particular widget to common style. Common style unfortunately uses active style's palette to draw the widget. S60Style defines Base to be transparent (to get the theme background shine through) and common style tries to use Base to draw lineEdit. End result is transparent lineEdit on webpage. This fix makes more educated deduction when it tries to see if style has been changed. This is related to QTBUG-4885.
