1/*! 2 \class BAbstractLayout 3 \ingroup interface 4 \ingroup layout 5 \ingroup libbe 6 7 \brief BLayout subclass providing convenience methods for derived 8 implementations. 9 10 This class is designed to reduce the amount of boilerplate code required to 11 write a BLayout subclass. In most cases, you classes should derive from 12 BAbstractLayout rather than BLayout. 13 14 When a BAbstractLayout is attached to a BView, many of the methods provided 15 by the BAbstractLayout class are forwarded to the BAbstractLayout's 16 owner BView. When a BAbstractLayout is viewless, these methods are handled 17 locally. 18 19 \warning This class is not yet finalized, if you use it in your software 20 assume that it will break some time in the future. 21*/ 22 23 24/*! 25 \name Constructors 26 27 @{ 28*/ 29 30 31/*! 32 \fn BAbstractLayout::BAbstractLayout() 33 \brief Construct a BAbstractLayout. 34*/ 35 36 37/*! 38 \fn BAbstractLayout::BAbstractLayout(BMessage* from); 39 \brief Archive constructor. 40*/ 41 42 43//@} 44 45 46/*! 47 \fn BSize BAbstractLayout::MinSize() 48 \copydoc BLayoutItem::MinSize() 49 50 The return value for this method is composed (using 51 BLayoutUtils::ComposeSize()) from the values returned by BaseMinSize() and 52 ExplicitMinSize(). 53*/ 54 55 56/*! 57 \fn BSize BAbstractLayout::MaxSize() 58 \copydoc BLayoutItem::MaxSize() 59 60 The return value for this method is composed (using 61 BLayoutUtils::ComposeSize()) from the values returned by BaseMaxSize() and 62 ExplicitMaxSize(). 63*/ 64 65 66/*! 67 \fn BSize BAbstractLayout::PreferredSize() 68 \copydoc BLayoutItem::PreferredSize() 69 70 The return value for this method is composed (using 71 BLayoutUtils::ComposeSize()) from the values returned by BasePreferredSize() 72 and ExplicitPreferredSize(). 73*/ 74 75 76/*! 77 \fn BAlignment BAbstractLayout::Alignment() 78 \copydoc BLayoutItem::Alignment() 79 80 The return value for this method is composed (using 81 BLayoutUtils::ComposeAlignment()) from the values returned by 82 BaseAlignment() and 83 ExplicitAlignment() 84*/ 85 86 87/*! 88 \name BAbstractLayout hooks 89 90 @{ 91*/ 92 93 94/*! 95 \fn BSize BAbstractLayout::BaseMinSize() 96 \brief Method to be implemented in derived classes return the minimum size 97 constraint for this BAbstractLayout. 98*/ 99 100 101/*! 102 \fn BSize BAbstractLayout::BaseMaxSize() 103 \brief Method to be implemented in derived classes return the maximum size 104 constraint for this BAbstractLayout. 105*/ 106 107 108/*! 109 \fn BSize BAbstractLayout::BasePreferredSize() 110 \brief Method to be implemented in derived classes return the preferred size 111 constraint for this BAbstractLayout. 112*/ 113 114 115/*! 116 \fn BAlignment BAbstractLayout::BaseAlignment() 117 \brief Method to be implemented in derived classes return the preferred 118 alignment for this BAbstractLayout. 119*/ 120 121 122//@} 123
