539 Given up to four items involved in a vertical spacing calculation-
540 (two rows * two columns), return the max vertical spacing for the-
541 row containing item1 (which may also include item2)-
542 We assume parent and item1 are not null.-
543-
544 If a particular row is split, then the spacings for that row and-
545 the following row are affected, and this function should be-
546 called with recalculate = true for both rows (note: only rows with both-
547 a label and a field can be split).-
548-
549 In particular:-
550-
551 1) the split label's row vspace needs to be changed to qMax(label/prevLabel, label/prevField)-
552 [call with item1 = label, item2 = null, prevItem1 & prevItem2 as before]-
553 2) the split field's row vspace needs to be changed to the label/field spacing-
554 [call with item1 = field, item2 = null, prevItem1 = label, prevItem2 = null]-
555-
556 [if the next row has one item, 'item']-
557 3a) the following row's vspace needs to be changed to item/field spacing (would-
558 previously been the qMax(item/label, item/field) spacings)-
559 [call with item1 = item, item2 = null, prevItem1 = field, prevItem2 = null]-
560-
561 [if the next row has two items, 'label2' and 'field2']-
562 3b) the following row's vspace needs to be changed to be qMax(field/label2, field/field2) spacing-
563 [call with item1 = label2, item2 = field2, prevItem1 = field, prevItem2 = null]-
564-
565 In the (common) non split case, we can just use the precalculated vspace (possibly qMaxed between-
566 label and field).-
567-
568 If recalculate is true, we expect:-
569 - parent != null-
570 - item1 != null-
571 - item2 can be null-
572 - prevItem1 can be null-
573 - if item2 is not null, prevItem2 will be null (e.g. steps 1 or 3 above)-
574 - if prevItem1 is null, prevItem2 will be null-

1005 \class QFormLayout-
1006 \since 4.4-
1007 \brief The QFormLayout class manages forms of input widgets and their associated labels.-
1008-
1009 \ingroup geomanagement-
1010 \inmodule QtWidgets-
1011-
1012 QFormLayout is a convenience layout class that lays out its-
1013 children in a two-column form. The left column consists of labels-
1014 and the right column consists of "field" widgets (line editors,-
1015 spin boxes, etc.).-
1016-
1017 Traditionally, such two-column form layouts were achieved using-
1018 QGridLayout. QFormLayout is a higher-level alternative that-
1019 provides the following advantages:-
1020-
1021 \list-
1022 \li \b{Adherence to the different platform's look and feel guidelines.}-
1023-
1024 For example, the-
1025 \l{http://developer.apple.com/library/mac/#documentation/UserExperience/Conceptual/AppleHIGuidelines/Intro/Intro.html}{\macos Aqua} and KDE guidelines specify that the-
1026 labels should be right-aligned, whereas Windows and GNOME-
1027 applications normally use left-alignment.-
1028-
1029 \li \b{Support for wrapping long rows.}-
1030-
1031 For devices with small displays, QFormLayout can be set to-
1032 \l{WrapLongRows}{wrap long rows}, or even to-
1033 \l{WrapAllRows}{wrap all rows}.-
1034-
1035 \li \b{Convenient API for creating label--field pairs.}-
1036-
1037 The addRow() overload that takes a QString and a QWidget *-
1038 creates a QLabel behind the scenes and automatically set up-
1039 its buddy. We can then write code like this:-
1040-
1041 \snippet code/src_gui_kernel_qformlayout.cpp 0-
1042-
1043 Compare this with the following code, written using QGridLayout:-
1044-
1045 \snippet code/src_gui_kernel_qformlayout.cpp 1-
1046 \endlist-
1047-
1048 The table below shows the default appearance in different styles.-
1049-
1050 \table-
1051 \header-
1052 \li QCommonStyle derived styles (except QPlastiqueStyle)-
1053 \li QMacStyle-
1054 \li QPlastiqueStyle-
1055 \li Qt Extended styles-
1056 \row-
1057 \li \inlineimage qformlayout-win.png-
1058 \li \inlineimage qformlayout-mac.png-
1059 \li \inlineimage qformlayout-kde.png-
1060 \li \inlineimage qformlayout-qpe.png-
1061 \row-
1062 \li Traditional style used for Windows, GNOME, and earlier-
1063 versions of KDE. Labels are left aligned, and expanding-
1064 fields grow to fill the available space. (This normally-
1065 corresponds to what we would get using a two-column-
1066 QGridLayout.)-
1067 \li Style based on the-
1068 \l{http://developer.apple.com/library/mac/#documentation/UserExperience/Conceptual/AppleHIGuidelines/Intro/Intro.html}{\macos Aqua} guidelines. Labels are right-aligned,-
1069 the fields don't grow beyond their size hint, and the-
1070 form is horizontally centered.-
1071 \li Recommended style for-
1072 \l{KDE applications}. Similar to MacStyle, except that the form-
1073 is left-aligned and all fields grow to fill the available-
1074 space.-
1075 \li Default style for Qt Extended styles. Labels are right-aligned,-
1076 expanding fields grow to fill the available space, and row-
1077 wrapping is enabled for long lines.-
1078 \endtable-
1079-
1080 The form styles can be also be overridden individually by calling-
1081 setLabelAlignment(), setFormAlignment(), setFieldGrowthPolicy(),-
1082 and setRowWrapPolicy(). For example, to simulate the form layout-
1083 appearance of QMacStyle on all platforms, but with left-aligned-
1084 labels, you could write:-
