Methods
Detailed Description
FontDialog allows the user to select a font. The dialog is initially invisible. You need to set the properties as desired first, then set visible to true or call open().
Here is a minimal example to open a font dialog and exit after the user chooses a font:
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 }
A FontDialog window is automatically transient for its parent window. So whether you declare the dialog inside an Item or inside a 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 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.
Property Documentation
currentFont : font
The font which the user selected.
This QML property was introduced in Qt 5.3.
font : font
The font which the user selected and accepted.
modality : Qt::WindowModality
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 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.
monospacedFonts : bool
Whether the dialog will show monospaced fonts or not.
nonScalableFonts : bool
Whether the dialog will show non scalable fonts or not.
proportionalFonts : bool
Whether the dialog will show proportional fonts or not.
scalableFonts : bool
Whether the dialog will show scalable fonts or not.
title : string
The title of the dialog window.
visible : bool
This property holds whether the dialog is visible. By default this is false.
See also modality.
Method Documentation
void close()
Closes the dialog.
void open()
Shows the dialog to the user. It is equivalent to setting visible to true.
