qt creator 5 lineedit array

knobby67 · 07-28-2014, 12:49 PM

Hi All,
hope someone can help me with this. I'm learning QT creator 5. I have a load of line edits to fill in on a form. These are saved to an array of strings which I can save as an XML file. Right now loading and saving is a nightmare because I can't work out how to get creator to set an array of line edits so now I save as

Code:

array[ 0 ] = ui->lineedit_0->text();
...
array[ 50 ] = ui->lineedit_50->text();

and reverse for load.
What I'd like to do is a basic

Code:

for( int j= 0;j < 50; j++ )
{
    array[ j ] = ui->lineedit[ j ]->text();
}

can I do this in QT creator?
Thanks in advance.

You can do something like the following:

Code:

QList<QLineEdit *> list = findChildren<QLineEdit *>();
foreach(QLineEdit *le, list) {
    // le->text() - output to file
    // or
    // read from file - le->setText()
}

Here's a link to a good Qt forum where you will get quicker responses: http://www.qtcentre.org/forums/4-Newbie

Also, note that the t in Qt is lower case.
