* Adjust sizes when snapping layout items to pixel gridJan Arve Sæther2016-03-021-12/+31
| | | | | | | | | When "importing" the size hints into the cells, make sure that the cells minimum sizes are ceiled up to the closest integer. Change-Id: Id00177468e8b1e12bc1231c7351b2136f94f7300 Task-number: QTBUG-41216 Reviewed-by: Paul Olav Tvete <paul.tvete@theqtcompany.com>

* Use C++ <cmath> instead of <math.h>Allan Sandfeld Jensen2015-02-161-2/+2
| | | | | | | | | | | | | | Including math.h can pollute the default namespace, and break some compilers if cmath versions of the method are declared as using. Switching to C++ math functions also greatly simplifies handling of float qreal as C++ automatically chooses the right method. [ChangeLog][QtCore][QtMath] qmath.h no longer includes math.h, so any sources depending on that indirect inclusion may fail to build.

* Update copyright headersJani Heikkinen2015-02-111-7/+7
| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>
* Add support for snapping to pixel gridJan Arve Saether2015-02-091-18/+41
| | | | | | | | | | | | | | | | | | | | | This enables us to do more intelligent distribution than simply doing the rounding on each individual items geometry (which often leads to larger spacings than specified). Instead of doing the rounding on the output geometries, we now do the snapping inside the layout engine. This allows us to do more intelligent distribution of items, and spacings should always be respected. There are some cases where items with fractional size hints might overlap with less than a pixel. This was also the case before this patch. Those cases are impossible to fix properly, since fractional size hints conflicts with the snapping in some cases. (Fractional size hints is normal for Text items.) Task-number: QTBUG-41216 Change-Id: I01a8bc3529f0b8b028d6eb0a530c751b67ac6f4e Reviewed-by: Paul Olav Tvete <paul.tvete@theqtcompany.com>

* Fixed a bug where spans did not always work in layouts.Jan Arve Saether2014-12-091-1/+1
| | | | | | | | | | | | | | | | The problem was that the span we stored in the multiCellMap was the "effective" span (i.e. the given span subtracted with the number of ignored rows it would span). Later we used that span to distribute its size across all its cells. However, since the span now could be smaller that the given span, we could sometimes fail to distribute to the last span(s). [ChangeLog][QtWidgets][layouts] Fixed a bug where spans sometimes didn't distribute themselves to the last cells they covered.

* Don't rely on hasChanged() in ensureGeometriesJan Arve Saether2014-12-011-1/+1
| | | | | | | | | | | | It can be removed now because we now have a better caching mechanism than before. It should therefore not be needed anymore. Since nothing else calls hasChanged, we can finally get rid of it. This simplifies the code and enables us to further improvements to the code.

| | | | | | | | | | | | | | | | | | | | | | | | | This tests * default spacing * explicit positive spacing * negative spacings Negative spacings that causes the layout to shrink down to 0 or a negative spacing are not supported. (But make sure they don't crash the whole engine) This is a partial cherry picked from qtquickcontrols.git/bc973dcf2163b25f2db74d974b252384bbee8d80) Only the Q_ASSERT had to be cherry-picked. This is because of that the qgridlayoutengine* is moved to qtbase. Therefore, any changes to qgridlayoutengine* won't be merged properly to dev (they will be lost).

* Move QGridLayoutEngine to QtGui moduleJan Arve Saether2013-12-091-0/+1641
For MacOS 10.6 the exported symbols must be the same regardless of debug/release configuration, because for debug builds it will by default link to a release library. We therefore cannot let some exported symbols depend on if QT_DEBUG is defined or not. We therefore introduce QGRIDLAYOUTENGINE_DEBUG, which is independent of debug/release configuration. The whole dump() function concept should probably be revisited, but I don't want to clutter this commit too much with such unrelated things.
