54 | * Provides a number of ready to use layouts (faces). It is used | ||
55 | * as an internal widget in @ref KDialogBase, but can also used as a | ||
56 | * widget of its own. | ||
57 | * | ||
58 | * It provides TreeList, IconList, Tabbed, Plain and Swallow layouts. | ||
59 | * | ||
60 | * The TreeList face provides a list in the left area and pages in the | ||
61 | * right. The area are separated by a movable splitter. The style is somewhat | ||
62 | * similar to the layout in the Control Center. A page is raised by | ||
63 | * selecting the corresponding tree list item. | ||
64 | * | ||
65 | * The IconList face provides an icon list in the left area and pages in the | ||
66 | * right. For each entry the Icon is on top with the text below. The style | ||
67 | * is somewhat similar to the layout of the Eudora configuation dialog box. | ||
68 | * A page is raised by selecting the corresponding icon list item. The | ||
69 | * preferred icon size is 32x32 pixels. | ||
70 | * | ||
71 | * The Tabbed face is a common tabbed widget. The procedure for creating a | ||
72 | * page is similar for creating a TreeList. This has the advantage that if | ||
73 | * your widget contain too many pages it is trivial to convert it into a | ||
74 | * TreeList. Just change the face in the KJanusWidget constructor to | ||
75 | * KJanusWidget::TreeList and you have a tree list layout instead. | ||
76 | * | ||
77 | * The Plain face provides an empty widget (QFrame) where you can place your | ||
78 | * widgets. The KJanusWidget makes no assumptions regarding the contents so | ||
79 | * you are free to add whatever you want. | ||
80 | * | ||
81 | * The Swallow face is provided in order to simplify the usage of existing | ||
82 | * widgets and to allow changing the visible widget. You specify the widget | ||
83 | * to be displayed by @ref #setSwallowedWidget(). Your widget will be | ||
84 | * reparented inside the widget. You can specify a Null (0) widget. A empty | ||
85 | * space is then displayed. | ||
86 | * | ||
87 | * For all modes it is important that you specify the @ref QWidget::minimumSize() | ||
88 | * on the page, plain widget or the swallowed widget. If you use a QLayout | ||
89 | * on the page, plain widget or the swallowed widget this will be taken care | ||
90 | * of automatically. The size is used when the KJanusWidget determines its | ||
91 | * own minimum size. You get the minimum size by using the | ||
92 | * @ref #minimumSizeHint() or @ref #sizeHint() methods. | ||
93 | * | ||
94 | * Pages that have been added in TreeList, IconList or Tabbed mode can be | ||
95 | * removed by simply deleting the page. | ||
96 | * | ||
97 | * @short Easy to use widget with many layouts | ||
