Detailed Description

The WebEngineHistory type can be accessed by using the WebEngineView.history property.

The WebEngineHistory type provides the following WebEngineHistoryModel data model objects:

• backItems, which contains the URLs of visited pages.
• forwardItems, which contains the URLs of the pages that were visited after visiting the current page.
• items, which contains the URLs of the back and forward items, as well as the URL of the current page.

The easiest way to use these models is to use them in a ListView as illustrated by the following code snippet:

ListView {
    id: historyItemsList
    anchors.fill: parent
    model: webEngineView.history.items
    delegate:
        Text {
            color: "black"
            text: model.title + " - " + model.url + " (" + model.offset + ")"
        }
}

The ListView shows the content of the corresponding model. The delegate is responsible for the format of the list items. The appearance of each item of the list in the delegate can be defined separately (it is not web engine specific).

The model roles title, url, and icon specify the title, URL, and favicon of the visited page. The offset role specifies the position of the page in respect to the current page (0). A positive number indicates that the page was visited after the current page, whereas a negative number indicates that the page was visited before the current page.

The data models can also be used to create a menu, as illustrated by the following code snippet:

    menuBar: ToolBar {
        id: navigationBar
        RowLayout {
            anchors.fill: parent
            ToolButton {
                enabled: currentWebView && (currentWebView.canGoBack || currentWebView.canGoForward)
                onClicked: historyMenu.open()
                text: qsTr("▼")
                Menu {
                    id: historyMenu
                    Instantiator {
                        model: currentWebView && currentWebView.history.items
                        MenuItem {
                            text: model.title
                            onTriggered: currentWebView.goBackOrForward(model.offset)
                            checkable: !enabled
                            checked: !enabled
                            enabled: model.offset
                        }

                        onObjectAdded: function(index, object) {
                            historyMenu.insertItem(index, object)
                        }
                        onObjectRemoved: function(index, object) {
                            historyMenu.removeItem(object)
                        }
                    }
                }
