Re: Help me to code for Sailfish OS

Three more questions:

1. I would like to navigate from the first page of an app (page 1) to another by swiping left (page 2).
GPSInfo does this by using a timer which creates the pageStack.pushAttached element of the second page.
Is there another / more elegant way to achieve this behaviour of changing from one to another page?

2. Is it possible to navigate from one pages button (page 1) to another page (page 3) and scroll this one to a specific item (for example a label) in the middle of this page (like anchors in HTML)?

3. Is it possible to use QLM's transform.matrix4x4 within sailfish apps to transform this element (for example to mirror a text field vertically)?

1. PageStack is stack, it's linear. You should have a page under your depth to go lower.
2. You can pass any arguments to a page you pushing to. Process it inside page to scroll
3. You can use transform property: https://doc.qt.io/qt-5/qml-qtquick-i...transform-prop

Navigating the stack backwards is clear (and easy). It's the possibility to navigate "forward" from page 1 to page 2 (without the need of a button, just swiping) which I'm looking for. ;)

Passing the "scroll-to-item" to page 3 was exactly what I thought of. But how to scroll the page?

1. okay, then attachedPage is your choice. Or use a Dialog instead of a Page and set acceptDestination
2. By using https://doc.qt.io/qt-5/qml-qtquick-l...AtIndex-method

I'll go for attachedPage. GPSInfo uses a timer to call attachedPage. What could be the reason for that (wouldn't be Component.onCompleted an easier way)?

There could be problems with transitions., Try it out and see. New API introduced pageStack.completeAnimation() method, which is probably you want to call before pageStack.pushAttached

How to work with images? I want to create app like this or this... so I need to choose image(s) from gallery and save it somewhere in the app - to local database?

I think this code should still work: https://bitbucket.org/mitakuuluu/mit...atarPicker.qml

Code:
import QtFeedback 5.0

HapticsEffect {
        id: activeEffect
        duration: 500 // in ms
        intensity: 0.2 // from 0 to 1 with 0.1 step-size
        running: button.pressed
}
Button {
        id: button
        width: text.width
        text: "Test"                                       
        anchors.horizontalCenter: parent.horizontalCenter
        onClicked: activeEffect.start()         
}
