Assign QStringList model object to listview

[jss193]

Hello everyone,

I have created a class :
fili .h

#ifndef LISTVIEW_H
#define LISTVIEW_H

#include <QWidget>
#include <QDialog>
#include <QStringListModel>
#include <QStringList>
#include <QAbstractItemView>
#include <QListView>

class listview : QDialog
{
public:
    listview(const QStringList &leaders, QWidget *parent);
    void insert();
    void del();
    QStringList leaders() const;

private:
    QListView *listView;
    QStringListModel *model;


};

.cpp file

#include "listview.h"

listview::listview(const QStringList &leaders, QWidget *parent):QDialog(parent){

    model = new QStringListModel(this);
    model->setStringList(leaders);

    listView = new QListView;
    listView->setModel(model);
    listView->setEditTriggers(QAbstractItemView::AnyKeyPressed | QAbstractItemView::DoubleClicked);
   

}


void listview::insert(){
    int row = listView->currentIndex().row();
   
    model->insertRows(row,1);
    QModelIndex index = model->index(row);
    listView->setCurrentIndex(index);
}

void listview::del(){
    model->removeRows(listView->currentIndex().row(),1);


}
QStringList listview::leaders() const{

    return leaders();

}

Know in my view I have a QListWidget, with 3 buttons Add, delete and insert buttons, I want them to run with methods of my class, then in my Mainwindow I should instantiate an object of this class, but I don't know how to link my object to my QListView, can someone help me?

Thanks

class MainWindow...
{
private:
    listview *view;
}
...
MainWindow::MainWindow(...)
{
    view = new listview();
    connect(ui->insertButton, &QPushButton::clicked, view, &listview::insert);
    // same for other 2 buttons
}

• QListView != QListWidget.
• you never give a parent, add to a layout or show your view so I'm not sure how the list view is displayed at all

Hello, thanks for your help, but problem remains still the same,
I think that I did not explain good enough, I have created that generic class shown above and afterwards I created a second view which prompts from a first ui, this second ui view contains a listView Widget whose I want to glue with my base class listview, so, First thing I tried was to create an object listview *aaaa;, then tried this, ui->listView->setModel(model), but I can't cause of model var from listview class is private.

How could I do this?

thanks!

Hi,

Then why not make the model a parameter of your dialog ? That way you can more easily share it between several classes.

You mean creating a new model for my second view and pass it to my listviewclass constructor instead of making it a private var of listview class?

Thanks

I mean creating one model and use it for both dialogs.

@SGaist you mean remove it from class and create the model in main function, true? Its a good idea. Thanks
