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 color dialog and exit after the user + chooses a color: + + \qml + import QtQuick 2.1 + import QtQuick.Dialogs 1.0 + + ColorDialog { + id: colorDialog + title: "Please choose a color" + onAccepted: { + console.log("You chose: " + colorDialog.color) + Qt.quit() + } + onRejected: { + console.log("Canceled") + Qt.quit() + } + Component.onCompleted: visible = true + } + \endqml + + A ColorDialog 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 ColorDialog will be a platform color dialog if + possible. If that isn't possible, then it will try to instantiate a + \l QColorDialog. If that also isn't possible, then it will fall back to a QML + implementation, DefaultColorDialog.qml. In that case you can customize the + appearance by editing this file. DefaultColorDialog.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::ColorDialog::accepted + + The \a accepted signal is emitted when the user has finished using the + dialog.
