| 55 | \class QDialogButtonBox
|
|---|
| 56 | \since 4.2
|
|---|
| 57 | \brief The QDialogButtonBox class is a widget that presents buttons in a
|
|---|
| 58 | layout that is appropriate to the current widget style.
|
|---|
| 59 |
|
|---|
| 60 | \ingroup application
|
|---|
| 61 | \mainclass
|
|---|
| 62 |
|
|---|
| 63 | Dialogs and message boxes typically present buttons in a layout that
|
|---|
| 64 | conforms to the interface guidelines for that platform. Invariably,
|
|---|
| 65 | different platforms have different layouts for their dialogs.
|
|---|
| 66 | QDialogButtonBox allows a developer to add buttons to it and will
|
|---|
| 67 | automatically use the appropriate layout for the user's desktop
|
|---|
| 68 | environment.
|
|---|
| 69 |
|
|---|
| 70 | Most buttons for a dialog follow certain roles. Such roles include:
|
|---|
| 71 |
|
|---|
| 72 | \list
|
|---|
| 73 | \o Accepting or rejecting the dialog.
|
|---|
| 74 | \o Asking for help.
|
|---|
| 75 | \o Performing actions on the dialog itself (such as resetting fields or
|
|---|
| 76 | applying changes).
|
|---|
| 77 | \endlist
|
|---|
| 78 |
|
|---|
| 79 | There can also be alternate ways of dismissing the dialog which may cause
|
|---|
| 80 | destructive results.
|
|---|
| 81 |
|
|---|
| 82 | Most dialogs have buttons that can almost be considered standard (e.g.
|
|---|
| 83 | \gui OK and \gui Cancel buttons). It is sometimes convenient to create these
|
|---|
| 84 | buttons in a standard way.
|
|---|
| 85 |
|
|---|
| 86 | There are a couple ways of using QDialogButtonBox. One ways is to create
|
|---|
| 87 | the buttons (or button texts) yourself and add them to the button box,
|
|---|
| 88 | specifying their role.
|
|---|
| 89 |
|
|---|
| 90 | \snippet examples/dialogs/extension/finddialog.cpp 1
|
|---|
| 91 |
|
|---|
| 92 | Alternatively, QDialogButtonBox provides several standard buttons (e.g. OK, Cancel, Save)
|
|---|
| 93 | that you can use. They exist as flags so you can OR them together in the constructor.
|
|---|
| 94 |
|
|---|
| 95 | \snippet examples/dialogs/tabdialog/tabdialog.cpp 2
|
|---|
| 96 |
|
|---|
| 97 | You can mix and match normal buttons and standard buttons.
|
|---|
| 98 |
|
|---|
| 99 | Currently the buttons are laid out in the following way if the button box is horizontal:
|
|---|
| 100 | \table 100%
|
|---|
| 101 | \row \o \inlineimage buttonbox-gnomelayout-horizontal.png GnomeLayout Horizontal
|
|---|
| 102 | \o Button box laid out in horizontal GnomeLayout
|
|---|
| 103 | \row \o \inlineimage buttonbox-kdelayout-horizontal.png KdeLayout Horizontal
|
|---|
| 104 | \o Button box laid out in horizontal KdeLayout
|
|---|
| 105 | \row \o \inlineimage buttonbox-maclayout-horizontal.png MacLayout Horizontal
|
|---|
| 106 | \o Button box laid out in horizontal MacLayout
|
|---|

|
|---|
| 108 | \o Button box laid out in horizontal WinLayout
|
|---|
| 109 | \endtable
|
|---|
| 110 |
|
|---|
| 111 | The buttons are laid out the following way if the button box is vertical:
|
|---|
| 112 |
|
|---|
| 113 | \table 100%
|
|---|
| 114 | \row \o \inlineimage buttonbox-gnomelayout-vertical.png GnomeLayout Vertical
|
|---|
| 115 | \o Button box laid out in vertical GnomeLayout
|
|---|
| 116 | \row \o \inlineimage buttonbox-kdelayout-vertical.png KdeLayout Vertical

|---|
| 117 | \o Button box laid out in vertical KdeLayout
|
|---|
| 118 | \row \o \inlineimage buttonbox-maclayout-vertical.png MacLayout Vertical

|---|
| 119 | \o Button box laid out in vertical MacLayout

|
|---|
| 121 | \o Button box laid out in vertical WinLayout
|
|---|
| 122 | \endtable
|
|---|
| 123 |
|
|---|
| 124 | Additionally, button boxes that contain only buttons with ActionRole or
|
|---|
| 125 | HelpRole can be considered modeless and have an alternate look on the mac:
|
|---|
| 126 |
|
|---|
| 127 | \table 100%
|
|---|
| 128 | \row \o \inlineimage buttonbox-mac-modeless-horizontal.png Screenshot of modeless horizontal MacLayout

|
|---|
| 131 | \o modeless vertical MacLayout
|
|---|
| 132 | \endtable
|
|---|
| 133 |
|
|---|
| 134 | When a button is clicked in the button box, the clicked() signal is emitted
|
|---|
| 135 | for the actual button is that is pressed. For convenience, if the button
|
|---|
| 136 | has an AcceptRole, RejectRole, or HelpRole, the accepted(), rejected(), or
|
|---|
| 137 | helpRequested() signals are emitted respectively.
|
|---|
| 138 |
|
|---|
| 139 | If you want a specific button to be default you need to call
|
|---|
| 140 | QPushButton::setDefault() on it yourself. However, if there is no default
|
|---|
| 141 | button set and to preserve which button is the default button across
|
|---|
| 142 | platforms when using the QPushButton::autoDefault property, the first push
|
|---|
| 143 | button with the accept role is made the default button when the
|
|---|
| 144 | QDialogButtonBox is shown,
