Add qtwidgetsglobal.h and qtwidgetsglobal_p.h The new modular configuration system requires one global header per module, that is included by all other files in this module. That header will later on #include the configuration file for Qt Widgets. For now it defines the Q_WIDGETS_EXPORT macro for this library.

Avoid adding widget to its own layout Widgets and layouts added or inserted to a layout are checked for: - Not being NULL - Not being the parent widget of a layout or the layout itself, respectively Without this commit, adding a widget to its own layout would result in a CPU-hogging infinite loop. Now, a warning is written to stderr and the add or insert function call is ignored. The checks are implemented as public functions of QLayoutPrivate and thus accessible in QLayout's descendants to be used in various "addWidget", "insertWidget", etc functions. Unlike 'classical' layouts like QGridLayout, QFormLayout does indeed accept widgets that are NULL. To not break this behavior, any call for the check functions first tests if the widget or layout, respectively, to test is NULL or not and calls the check only in the latter case. Automated tests for QBoxLayout, QGridLayout, and QFormLayout were added. For an unpatched Qt 5.3, each of those automated tests will freeze as explained in QTBUG-40609. For a fixed version, warning messages about invalid parameters to addWidget/addLayout/... calls will be read by QTest::ignoreMessage, resulting in a passed test.

QLayout - Introduce vertical and horizontal layout constraints In most situations the simple setSizeConstraint is sufficient to get the sizeConstaint the user wants. However in certain other situations the QLayout size constraint demanding same vertical and horizontal behavior could simply be extremely annoying. This patch fixes a design-flaw as it makes perfectly sense to have a fixed sized or minimum size constraint in one orientation and having it something else (e.g minMax) in the another. Likely the old logic was that the user could use setMinimumWidth and setMaximumWidth on the widget itself (and similar for height) to get this behavior, but on 2+ monitor systems with different DPR that is not really an option (at least not a good one). [ChangeLog][QWidgets][QLayout] Introduced a vertical and horizontal size constraint in layout as the size constraint behavior can depend on the orientation.
