TableView Resizing Columns Signal

QtStudent101

hey, I'm kind of new to qml and Im trying to find what signal is being emitted when resizing a column in table view.
up until now I used the WidthChanged signal, but the thing is, I want to change other columns after resizing a specific column.
I want to make the table to always fit the screen, even when resizing, so I guess I need to know when I'm resizing and not just when the column width is changed, because then every time I will resize a column the Colum which his width will also change as a result will emit the signal as well (and so on...) and I will get unwanted behavior.

here is an example of a table that fills the entire window with resizable Columns.
im attaching the qml file, the main.cpp and the tableModel.h

Main.qml :

import QtQuick
import QtQuick.Controls
import QtQuick.Window

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

    TableView {
        id: tableViewid
        width: parent.width
        height: parent.height
        boundsBehavior: Flickable.StopAtBounds
        columnSpacing: 1
        rowSpacing: 1
        clip: true
        resizableColumns: true

        model: tableModel  // Use the context property 'tableModel'

        delegate: Rectangle {
            implicitWidth: (mainWindow.width-(tableViewid.rowSpacing*tableModel.columnCount()))/tableModel.columnCount()
            implicitHeight: 50
            Text {
                text: display 
            }
        }
    }
}

main.cpp :

#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QQmlContext>
#include "../TableViewPlayGround/tablemodel.h"

int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);

    qmlRegisterType<TableModel>("example.com", 1, 0, "tableModel");

    QQmlApplicationEngine engine;
    QObject::connect(
        &engine,
        &QQmlApplicationEngine::objectCreationFailed,
        &app,
        []() { QCoreApplication::exit(-1); },
        Qt::QueuedConnection);
    engine.loadFromModule("TableViewPlayGround", "Main");

    TableModel* model = new TableModel();
    engine.rootContext()->setContextProperty(QString("tableModel"), model);

    return app.exec();
}

tablemodel.h :

#include <qqml.h>
#include <QAbstractTableModel>

class TableModel : public QAbstractTableModel
{
    Q_OBJECT
    QML_ELEMENT
    QML_ADDED_IN_VERSION(1, 1)

public:
    TableModel()
    {
        for (int i = 1; i <= 50; ++i) {
            elements.append(i);
        }
    }

    int rowCount(const QModelIndex & = QModelIndex()) const override
    {
        return elements.size() / 5 + (elements.size() % 5 != 0);
    }

    int columnCount(const QModelIndex & = QModelIndex()) const override
    {
        return 5;
    }

    QVariant data(const QModelIndex &index, int role) const override
    {
        int elementIndex = index.row() * 5 + index.column();
        if (elementIndex < elements.size() && role == Qt::DisplayRole) {
            return QString("%1").arg(elements[elementIndex]);
        }

        return QVariant();
    }

    QHash<int, QByteArray> roleNames() const override
    {
        return { {Qt::DisplayRole, "display"} };
    }

private:
    QList<int> elements;
};

thanks in advance for the help!
