* Update contact information in license headers.Sergio Ahumada2012-08-011-2/+2
| | | | | | | | | | | | | - Replace Nokia contact email address with Qt Project website. - Remove "All rights reserved" line from license headers. As in the past, to avoid rewriting various autotests that contain line-number information, an extra blank line has been inserted at the end of the license text to ensure that this commit does not change the total number of lines in the license header.

* Improve performance of hfw in qgridlayoutengine by adding more caching.Jan-Arve Sæther2010-11-191-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous code tried to do caching of queries with constraints too, but it's usecase was rather limited. The caching worked for the simple case of effectiveSizeHint(Qt::PreferredSize, QSize(10, -1)); effectiveSizeHint(Qt::PreferredSize, QSize(10, -1)); // uses cache The problem was that if somebody called this sequence: effectiveSizeHint(Qt::PreferredSize, QSize(10, -1)); effectiveSizeHint(Qt::PreferredSize, QSize(-1, -1)); effectiveSizeHint(Qt::PreferredSize, QSize(10, -1)); Each call would disregard the cache because the constraint was different. Now the pattern is used in the qgridlayoutengine itself when we calculate hfw: (yes, height-for-width). First, we ask for the horizontal size hints with no constraints. Then, we'll ask for the vertical size hints with constraints. Since horizontal and vertical ultimately comes from the same function (effectiveSizeHint) it will invalidate the cache each time. The solution is to add another cache for the sizeHints with constraints. The most notable improvement is in the hfw, nested case. Result: RESULT : tst_QGraphicsLinearLayout::heightForWidth():"hfw, nested": 546 msecs per iteration (total: 546, iterations: 1) RESULT : tst_QGraphicsLinearLayout::heightForWidth():"hfw, nested": 0.000029 msecs per iteration (total: 62, iterations: 2097152) Improvement: 18,827,586 times faster (!!)

* Revert "Fix (implement!) hfw/wfh in QGridLayoutEngine"Thierry Bastian2010-09-301-6/+0
| | | | | | | | | | | This reverts commit 62b5ef3cc1306e46a4042b14867f2f92d9a110f3. The implementation of hfw from this patch is unfortunately not robust enough. It doesn't manage correctly the constraints on the layouts and the cell spans. It caused bad behaviour or regressions seen in tasks: QTBUG-13547, QTBUG-13067, QTBUG-13549, and more Reviewed-By: ogoffart

* Reduced memory footprint of QGraphicsWidget.jasplin2009-05-071-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit reduces the memory footprint of QGraphicsWidget by around 40% (from around 663 bytes to around 409 bytes - measured using /proc/<pid>/statm on Linux - see 'man 5 proc'). The technique used is to lazily allocate (on the heap) certain data structures (i.e. not allocate them unless they are needed): - QGraphicsLayoutItemPrivate::userSizeHints => used only if the size, width, or height is explicitly set - QGraphicsWidgetPrivate::margins => used only if the contents margins are accessed - QGraphicsWidgetPrivate::windowFrameMargins => used only if the window frame margins are accessed - QGraphicsWidgetPrivate::windowData => used only if the graphics widget is a window In addition, a few unused data members (and related code) were removed: - QGraphicsWidgetPrivate::contentsRect - QGraphicsWidgetPrivate::mouseDelta - QGraphicsWidgetPrivate::*LayoutItemMargin Reviewed-by: andreas Task-number: 251592
