QML not displaying correctly

[clarity]

Hey,

I'm using the Tabs component. The first tab (Blocks) displays correctly, but when I navigate to the Transactions tabs, the TextArea goes off the screen.

Here's the code:
import QtQuick 2.5
import QtQuick.Controls 1.4
import QtQuick.Layouts 1.2
import QtQuick.Dialogs 1.2

ApplicationWindow {
id: mainWindow
visible: true
width: 640
height: 480
title: qsTr("Block Explorer")

signal prevPressed();
signal nextPressed();

menuBar: MenuBar {
    Menu {
        title: qsTr("File")
        MenuItem {
            text: qsTr("&Open")
            onTriggered: console.log("Open action triggered");
        }
        MenuItem {
            text: qsTr("Exit")
            onTriggered: Qt.quit();
        }
    }
}


TabView {
    anchors.fill: parent

    Tab {
        title: "Blocks"
        Item {
            anchors.centerIn: parent

            TextArea {
                id: block
                x: 107
                y: 62
                width: 392
                height: 327
                visible: true
                frameVisible: true
                tabChangesFocus: false
                readOnly: true
                text: Test.text
            }

            Button {
                id: previous
                x: 240
                y: 400
                onClicked: mainWindow.prevPressed()
                text: qsTr("Previous")
            }

            Button {
                id: next
                x: 340
                y: 400
                onClicked: mainWindow.nextPressed()
                text: qsTr("Next")
            }

        }
    }
    Tab {
        title: "Transactions"
        anchors.centerIn: parent

        TextArea {
            id: transactions
            x: 107
            y: 62
            width: 392
            height: 327
            visible: true
            frameVisible: true
            tabChangesFocus: false
            readOnly: true
            text: "Transactions"
        }

        Button {
            id: transaction_previous
            x: 240
            y: 400
            onClicked: mainWindow.prevPressed()
            text: qsTr("Previous")
        }

        Button {
            id: transaction_next
            x: 340
            y: 400
            onClicked: mainWindow.nextPressed()
            text: qsTr("Next")
        }
    }
    Tab {
        title: "State"
        anchors.centerIn: parent

        Rectangle {
            color: "green"
        }
    }
}

MessageDialog {
    id: messageDialog
    title: qsTr("May I have your attention, please?")

    function show(caption) {
        messageDialog.text = caption;
        messageDialog.open();
    }
}

}

Whoops, forgot to put the second tab in an Item

Here's the fixed code:
import QtQuick 2.5
import QtQuick.Controls 1.4
import QtQuick.Layouts 1.2
import QtQuick.Dialogs 1.2

ApplicationWindow {
id: mainWindow
visible: true
width: 640
height: 480
title: qsTr("Block Explorer")

signal prevPressed();
signal nextPressed();

menuBar: MenuBar {
    Menu {
        title: qsTr("File")
        MenuItem {
            text: qsTr("&Open")
            onTriggered: console.log("Open action triggered");
        }
        MenuItem {
            text: qsTr("Exit")
            onTriggered: Qt.quit();
        }
    }
}


TabView {
    anchors.fill: parent

    Tab {
        title: "Blocks"
        Item {
            anchors.centerIn: parent

            TextArea {
                id: block
                x: 107
                y: 62
                width: 392
                height: 327
                visible: true
                frameVisible: true
                tabChangesFocus: false
                readOnly: true
                text: Test.text
            }

            Button {
                id: previous
                x: 240
                y: 400
                onClicked: mainWindow.prevPressed()
                text: qsTr("Previous")
            }

            Button {
                id: next
                x: 340
                y: 400
                onClicked: mainWindow.nextPressed()
                text: qsTr("Next")
            }

        }
    }
    Tab {
        title: "Transactions"
        Item {
            anchors.centerIn: parent

            TextArea {
                id: transactions
                x: 107
                y: 62
                width: 392
                height: 327
                visible: true
                frameVisible: true
                tabChangesFocus: false
                readOnly: true
                text: "Transactions"
            }

            Button {
                id: transaction_previous
                x: 240
                y: 400
                onClicked: mainWindow.prevPressed()
                text: qsTr("Previous")
            }

            Button {
                id: transaction_next
                x: 340
                y: 400
                onClicked: mainWindow.nextPressed()
                text: qsTr("Next")
            }
        }
    }
    Tab {
        title: "State"
        anchors.centerIn: parent

        Rectangle {
            color: "green"
        }
    }
}

MessageDialog {
    id: messageDialog
    title: qsTr("May I have your attention, please?")

    function show(caption) {

        messageDialog.open();
    }
}
