Making global QStandardItemModel

[SykeS]

Hi!

I'm trying to introduce myself to QT. I want to make a simple program with two main functions: 1). managing contacts, 2). creating PDF with details of chosen contact. I read about model/view programming in QT and I know I have to use QStandardItemModel, but: where I have to define and implement my model if I want to access it from all dialogs in my app? How to access it?

Cheers,

In this case I would put the model code in mainwindow.cpp

Each dialogue is generally implemented as a separate class and #included in mainwindow.

so you can have something like

void MainWindow::on_NewContactButton_clicked()
{
    newContactDialog ncd(this);
}

void MainWindow::on_NewContactButton_clicked()
{
    newContactDialog ncd(this);
}

To copy to clipboard, switch view to plain text mode 

and the model would be accessable to ncd.

Incidentally, you have not mentioned where you are storing your contacts, if you are using a database you may be better off using a prebuilt model such as QSqlQueryModel.
