Detailed Description

Dialog is a container type for displaying a modal dialog on the screen. It displays customizable content and one or two buttons, for positive and negative actions.

Dialog displays no content other than a title text and one or two buttons by default. To display simply a text message or text input, InputDialog can be used for convenience.

Example Usage

For example, to display a Dialog with an AppImage, the following code can be used:

 App {
   Page {

     AppButton {
       anchors.centerIn: parent
       text: "Custom Dialog"
       onClicked: customDialog.open()
     }

     Dialog {
       id: customDialog
       title: "Do you think this is awesome?"
       positiveActionLabel: "Yes"
       negativeActionLabel: "No"
       onCanceled: title = "Think again!"
       onAccepted: close()

       AppImage { //will be placed inside the dialogs content area
         anchors.fill: parent
         source: "../assets/vplay-logo.png"
         fillMode: Image.PreserveAspectFit
       }
     }
   }
 }
