\ingroup qtquick-visual
\ingroup dialogs
\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.
*/
/*!
\class QQuickPlatformFontDialog
\inmodule QtQuick.Dialogs

\brief The QQuickPlatformFontDialog class provides a font dialog
The dialog is implemented via the QQuickPlatformFontDialogHelper when possible;
otherwise it falls back to a QFontDialog or a QML implementation.

/*!
\qmlproperty bool FontDialog::visible
This property holds whether the dialog is visible. By default this is
false.
\sa modality
*/
/*!
\qmlproperty Qt::WindowModality FontDialog::modality
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.WindowModal.
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.
*/
/*!
\qmlmethod void FontDialog::open()
Shows the dialog to the user. It is equivalent to setting \l visible to
true.
*/
/*!
\qmlmethod void FontDialog::close()
Closes the dialog.
*/
/*!
\qmlproperty string FontDialog::title
The title of the dialog window.
*/
/*!
\qmlproperty bool FontDialog::scalableFonts
Whether the dialog will show scalable fonts or not.
*/
/*!
\qmlproperty bool FontDialog::nonScalableFonts
Whether the dialog will show non scalable fonts or not.
*/
/*!
\qmlproperty bool FontDialog::monospacedFonts
Whether the dialog will show monospaced fonts or not.
*/
/*!
\qmlproperty bool FontDialog::proportionalFonts
Whether the dialog will show proportional fonts or not.
*/
/*!
\qmlproperty font FontDialog::font
The font which the user selected and accepted.
*/
/*!
\qmlproperty font FontDialog::currentFont
The font which the user selected.
