| \brief Dialog component for choosing a font. |
| \since 5.2 |
| |
| FontDialog allows the user to select a font. The dialog is initially |
| invisible. You need to set the properties as desired first, then set |
| \l visible to true or call \l open(). |
| |
| Here is a minimal example to open a font dialog and exit after the user |
| chooses a font: |
| |
| \qml |
| import QtQuick 2.2 |
| import QtQuick.Dialogs 1.1 |
| |
| FontDialog { |
| id: fontDialog |
| title: "Please choose a font" |
| font: Qt.font({ family: "Arial", pointSize: 24, weight: Font.Normal }) |
| onAccepted: { |
| console.log("You chose: " + fontDialog.font) |
| Qt.quit() |
| } |
| onRejected: { |
| console.log("Canceled") |
| Qt.quit() |
| } |
| Component.onCompleted: visible = true |
| } |
| \endqml |
| |
| A FontDialog window is automatically transient for its parent window. So |
| whether you declare the dialog inside an \l Item or inside a \l Window, the |
| dialog will appear centered over the window containing the item, or over |
| the Window that you declared. |
| |
| The implementation of FontDialog will be a platform font dialog if |
| possible. If that isn't possible, then it will try to instantiate a |
| \l QFontDialog. If that also isn't possible, then it will fall back to a QML |
| implementation, DefaultFontDialog.qml. In that case you can customize the |
| appearance by editing this file. DefaultFontDialog.qml contains a Rectangle |
| to hold the dialog's contents, because certain embedded systems do not |
| support multiple top-level windows. When the dialog becomes visible, it |
| will automatically be wrapped in a Window if possible, or simply reparented |
| on top of the main window if there can only be one window. |
| */ |
| |
| /*! |
| \qmlsignal QtQuick::Dialogs::FontDialog::accepted |
| |
| The \a accepted signal is emitted when the user has finished using the |
| dialog. You can then inspect the \a font property to get the selection. |
| |
| Example: |
| |
| \qml |
| FontDialog { |
| onAccepted: { console.log("Selected font: " + font) } |
| } |
| \endqml |
| |
| The corresponding handler is \c onAccepted. |
| */ |
| |
| /*! |
| \qmlsignal QtQuick::Dialogs::FontDialog::rejected |
| |
| The \a rejected signal is emitted when the user has dismissed the dialog, |
| either by closing the dialog window or by pressing the Cancel button. |
| |
| The corresponding handler is \c onRejected. |
| */ |
| |

| |
| Whether the dialog should be shown modal with respect to the window |
| containing the dialog's parent Item, modal with respect to the whole |
| application, or non-modal. |
| |
| By default it is \c Qt.NonModal. |
| |
| Modality does not mean that there are any blocking calls to wait for the |
| dialog to be accepted or rejected; it's only that the user will be |
| prevented from interacting with the parent window and/or the application |
| windows at the same time. |
| |
| You probably need to write an onAccepted handler if you wish to change a |
| font after the user has pressed the OK button, or an onCurrentFontChanged |
| handler if you wish to react to every change the user makes while the |
| dialog is open. |
