How to set ToolTip's properties (delay, timeout, etc) globally?

J0hnny

Is there a way to set ToolTip's properties like "delay", "timeout" and "visible" globally in an application to avoid boilerplate code which sets the same properties in each item which needs a ToolTip? It seems like a standard use case when all controls have the same behavior of tooltips in an app, isn't it?
Below is an example of using setTooltipProperties() to minimize code duplication, but still it looks like boilerplate code. It works for both desktop (mouse) and mobile (touch).

import QtQuick 2.8
import QtQuick.Window 2.2
import QtQuick.Controls 2.2
import QtQuick.Layouts 1.3

Window {
    id: window
    visible: true
    width: 640
    height: 480
    property bool isDesktop: switch (Qt.platform.os) {
                             case "android":
                             case "ios":
                                 return false;
                             default:
                                 return true;
                             }

    function setTooltipProperties(tooltip, target)
    {
        tooltip.visible = Qt.binding(function () {
            return tooltip.text === "" ?
                        false
                      :  isDesktop ? target.hovered : target.pressed
        })

        tooltip.delay = 2000
        tooltip.timeout = 3000
    }

    ColumnLayout {
        Button {
            text: "1"
            ToolTip.text: "Tooltip 1"
            Component.onCompleted: setTooltipProperties(ToolTip, this)
        }

        Button {
            text: "2"
            ToolTip.text: "Tooltip 2"
            Component.onCompleted: setTooltipProperties(ToolTip, this)
        }
    }
}

You could attempt to build your own ToolTip and self manage it?

Using a Timer to count after a onEnter for the specific control, and then count again for a timeout, stopping the timer on an exit...

Use rectangle with a label inside and size it in accordance with the text size and a bit of padding to make it fancy... Will give you much more control and you can basically add anything to the tooltip

use connections between your controls events to functions that manage the timer
