561 Given up to four items involved in a vertical spacing calculation-
562 (two rows * two columns), return the max vertical spacing for the-
563 row containing item1 (which may also include item2)-
564 We assume parent and item1 are not null.-
565-
566 If a particular row is split, then the spacings for that row and-
567 the following row are affected, and this function should be-
568 called with recalculate = true for both rows (note: only rows with both-
569 a label and a field can be split).-
570-
571 In particular:-
572-
573 1) the split label's row vspace needs to be changed to qMax(label/prevLabel, label/prevField)-
574 [call with item1 = label, item2 = null, prevItem1 & prevItem2 as before]-
575 2) the split field's row vspace needs to be changed to the label/field spacing-
576 [call with item1 = field, item2 = null, prevItem1 = label, prevItem2 = null]-
577-
578 [if the next row has one item, 'item']-
579 3a) the following row's vspace needs to be changed to item/field spacing (would-
580 previously been the qMax(item/label, item/field) spacings)-
581 [call with item1 = item, item2 = null, prevItem1 = field, prevItem2 = null]-
582-
583 [if the next row has two items, 'label2' and 'field2']-
584 3b) the following row's vspace needs to be changed to be qMax(field/label2, field/field2) spacing-
585 [call with item1 = label2, item2 = field2, prevItem1 = field, prevItem2 = null]-
586-
587 In the (common) non split case, we can just use the precalculated vspace (possibly qMaxed between-
588 label and field).-
589-
590 If recalculate is true, we expect:-
591 - parent != null-
592 - item1 != null-
593 - item2 can be null-
594 - prevItem1 can be null-
595 - if item2 is not null, prevItem2 will be null (e.g. steps 1 or 3 above)-
596 - if prevItem1 is null, prevItem2 will be null-

1027 \class QFormLayout-
1028 \since 4.4-
1029 \brief The QFormLayout class manages forms of input widgets and their associated labels.-
1030-
1031 \ingroup geomanagement-
1032 \inmodule QtWidgets-
1033-
1034 QFormLayout is a convenience layout class that lays out its-
1035 children in a two-column form. The left column consists of labels-
1036 and the right column consists of "field" widgets (line editors,-
1037 spin boxes, etc.).-
1038-
1039 Traditionally, such two-column form layouts were achieved using-
1040 QGridLayout. QFormLayout is a higher-level alternative that-
1041 provides the following advantages:-
1042-
1043 \list-
1044 \li \b{Adherence to the different platform's look and feel guidelines.}-
1045-
1046 For example, the-
1047 \l{http://developer.apple.com/library/mac/#documentation/UserExperience/Conceptual/AppleHIGuidelines/Intro/Intro.html}{\macos Aqua} and KDE guidelines specify that the-
1048 labels should be right-aligned, whereas Windows and GNOME-
1049 applications normally use left-alignment.-
1050-
1051 \li \b{Support for wrapping long rows.}-
1052-
1053 For devices with small displays, QFormLayout can be set to-
1054 \l{WrapLongRows}{wrap long rows}, or even to-
1055 \l{WrapAllRows}{wrap all rows}.-
1056-
1057 \li \b{Convenient API for creating label--field pairs.}-
1058-
1059 The addRow() overload that takes a QString and a QWidget *-
1060 creates a QLabel behind the scenes and automatically set up-
1061 its buddy. We can then write code like this:-
1062-
1063 \snippet code/src_gui_kernel_qformlayout.cpp 0-
1064-
1065 Compare this with the following code, written using QGridLayout:-
1066-
1067 \snippet code/src_gui_kernel_qformlayout.cpp 1-
1068 \endlist-
1069-
1070 The table below shows the default appearance in different styles.-
1071-
1072 \table-
1073 \header-
1074 \li QCommonStyle derived styles (except QPlastiqueStyle)-
1075 \li QMacStyle-
1076 \li QPlastiqueStyle-
1077 \li Qt Extended styles-
1078 \row-
1079 \li \inlineimage qformlayout-win.png-
1080 \li \inlineimage qformlayout-mac.png-
1081 \li \inlineimage qformlayout-kde.png-
1082 \li \inlineimage qformlayout-qpe.png-
1083 \row-
1084 \li Traditional style used for Windows, GNOME, and earlier-
1085 versions of KDE. Labels are left aligned, and expanding-
1086 fields grow to fill the available space. (This normally-
1087 corresponds to what we would get using a two-column-
1088 QGridLayout.)-
1089 \li Style based on the-
1090 \l{http://developer.apple.com/library/mac/#documentation/UserExperience/Conceptual/AppleHIGuidelines/Intro/Intro.html}{\macos Aqua} guidelines. Labels are right-aligned,-
1091 the fields don't grow beyond their size hint, and the-
1092 form is horizontally centered.-
1093 \li Recommended style for-
1094 \l{KDE applications}. Similar to MacStyle, except that the form-
1095 is left-aligned and all fields grow to fill the available-
1096 space.-
1097 \li Default style for Qt Extended styles. Labels are right-aligned,-
1098 expanding fields grow to fill the available space, and row-
1099 wrapping is enabled for long lines.-
1100 \endtable-
1101-
1102 The form styles can be also be overridden individually by calling-
1103 setLabelAlignment(), setFormAlignment(), setFieldGrowthPolicy(),-
1104 and setRowWrapPolicy(). For example, to simulate the form layout-
1105 appearance of QMacStyle on all platforms, but with left-aligned-
1106 labels, you could write:-
