How to populate values in my Qdialogbox's linedits?

learnist

in my main window, i have a qlistwidget named employee_list and the items in this qlistwidget are like this
<FIRM-1> name="Anna Ken" age="25" job="QtMaster",
<FIRM-2> name="Sir Ron" age="50" job="QtSlave"

so when i click the items in employee_list qlistwidget, a dialogbox shows up with 3 fields name,age,job like this

but when this dialog box shows up, i want the fields name,age,job to be populated , like this, How can i achieve this ?

so far i have tried this.

void MainWindow::on_employee_list_itemDoubleClicked(QListWidgetItem* item)
{
    QString test = item->text();             // getting the item text
    std::string test_s = test.toStdString();  //converting it to string from Qstring
    string name_part = "";                     //creating a variable in which name will be stored

        int name_pos = test_s.find("name=\"");
        for (int i = name_pos + 6; i < test_s.length();i++)
        {
            if (test_s[i] != '\"')
                name_part += test_s[i];
            else
                break;                         //extracting name in the item's text, after this the name_part variable value is Sir ron.  // similar code for extarcting age and job.
            
    if (test_s.find("<FIRM-1>") != std::string::npos)   //if item contains text <FIRM-1> then show this dialogue
    {
        GrpComd grpComd;   //creating instance of dialog
        grpComd.exec();    //showing it 
              
       grpComd.name_lineedit->settext(name_part);  // i tried this to populate name in name_linedit but getting error , access violation reading location
    }
}

@learnist Did you check is their any string coming from Item->text(); ?

@learnist Did you actually debug your code to see what happens?

@shashikumar Yes, i am getting string, only problem is propulating that into dialog box.

@learnist

        grpComd.exec();    //showing it 
              
       grpComd.name_lineedit->settext(name_part);  // i tried this to populate name in name_linedit but getting error , access violation reading location

The second line compiles, does it? With settext ? ~~Your code compiles with the {s & }s you show, right?~~ OK, I see you've done some editing of the code you have to shorten.

Did you try doing the second line before the first one, if you want to put the text in before you showed the user the modal dialog?

Hi,

exec is a blocking call so basically you modify your dialog content after you dismiss it.
