problems with right margin when use RowLayout

[cdeads]

Hello everyone! Hope you are OK)
I have a little question about margin.
Well now, I created simple interface. When I'm compiling and run it. All is looks like on the next screenshot
Pay attention on right margin from buttons "Open" and right window's border - all is OK now.
But when I'm maximizing window margin is gone:

And when I'm restoring it default size margin don't get back:

Here is a part of code what depends it:

Rectangle {
id: filesFieldColumn
anchors.right: parent.right
anchors.left: parent.left
anchors.top: topRightSectorLabelWrapper.bottom
anchors.bottom: parent.bottom
anchors.topMargin: screenTools.bigMarginValue
color: screenTools.windowLiteShadeColor

            ColumnLayout {
                 id: inputFileFieldRow
                 anchors.left: parent.left
                 anchors.right: parent.right
                 anchors.leftMargin: screenTools.bigMarginValue
                 height: implicitHeight
                 width: parent.width
                 RowLayout {
                     id: inputFileFieldLayout
                     TextField {
                         id: inputFileField
                         selectByMouse: true
                         placeholderText: qsTr("Enter path to input file")
                         font.pointSize: screenTools.defaultFontPointSize
                         height: screenTools.textFieldFixedHeight
                         Layout.fillWidth: true
                     }
                     Button {
                         id: openInputFileButton
                         text: qsTr("Open")
                         Layout.alignment: Qt.AlignHCenter | Qt.AlignVCenter
                         Layout.fillWidth: false
                         Layout.rightMargin: screenTools.bigMarginValue
                         font.pointSize: screenTools.defaultFontPointSize
                         height: screenTools.textFieldFixedHeight
                     }
                 }

                 RowLayout {
                     id: outputFileFieldRow
                     TextField {
                         id: outputFileField
                         selectByMouse: true
                         placeholderText: qsTr("Enter path to output file")
                         font.pointSize: screenTools.defaultFontPointSize
                         height: screenTools.textFieldFixedHeight
                         Layout.fillWidth: true
                     }
                     Button {
                         id: openOutputFileButton
                         text: qsTr("Open")
                         Layout.rightMargin: screenTools.bigMarginValue
                         font.pointSize: screenTools.defaultFontPointSize
                         height: screenTools.textFieldFixedHeight
                     }
                  }
            }
       } 

I'm using windows10, Qt Version 5.13.0, Qt Creator 4.9.2

Please hint me if I something do wrong.
Early thanks for your help!

Just wrote a simple example. Cannot to reproduce at least under linux and Qt 5.12.3:

ApplicationWindow {
    id: root
    width: 800
    height: 600
    visible: true

    ColumnLayout {
        anchors {
            left: parent.horizontalCenter
            right: parent.right
            margins: 10
        }
        spacing: 10

        RowLayout {
            width: parent.width; spacing: 10
            TextField { Layout.fillWidth: true }
            Button { text: "Test" }
        }

        RowLayout {
            width: parent.width; spacing: 10
            TextField { Layout.fillWidth: true }
            Button { text: "Test" }
        }

        RowLayout {
            width: parent.width; spacing: 10
            TextField { Layout.fillWidth: true }
            Button { text: "Test" }
        }

        RowLayout {
            width: parent.width; spacing: 10
            TextField { Layout.fillWidth: true }
            Button { text: "Test" }
        }

        RowLayout {
            width: parent.width; spacing: 10
            TextField { Layout.fillWidth: true }
            Button { text: "Test" }
        }
    }
}

Try to start with a small example.

I think your issue isn't about the margin, but with your screen,

your margin doesn't dispear but you can't see all your rectangle since they are not really right adjusted try more to use more of items and anchors.fill: parent as much as you can for the all thing to be responsive.

something like that maybe:

Window
{
    // your code of your window
    RowLayout
    {
        anchors.fill: parent

        Item
        {
            Layout.preferedWidth = parent * 0.5
            Layout.fillHeight = true

            //code first column
        }

        Item
        {
            Layout.preferedWidth = parent * 0.5
            Layout.fillHeight = true

            //code second column
        }
}

with this you sure you always see all of what you have

@darta Yep, your advice helped for me) I've did all as you said and when I placed
anchors.fill: parent in ColumnLayout and Layout.preferredWidth: parent * 0.5 to chillds Items, bug's gone .
Thank you very much!
May the force be with you)

@cdeads
I think your problem is actually here

                 anchors.left: parent.left
                 anchors.right: parent.right
                 anchors.leftMargin: screenTools.bigMarginValue
                 height: implicitHeight
                 width: parent.width

you give it left and right anchors and a width and margins, that's conflicting and you should get a couple of console warnings during runtime at the very least
