Connect closing dialog with a Qt List Widget

[Dy3zz]

HI. So my problem is the next: I have a main window with a button that opens a dialog box. Inside that dialog box I create a QStringList and all i want is to return this list from dialog to a QListWidget in main widget when I close the dialog. I suppose it can be solved with signals but i dont know how to use it.

This is how I open the dialog from main widget:

void home::on_AddPeopleBut_clicked()
{
 addpeople* window=new addpeople(this);
 window->show();
}

In dialog i have the next function :

QStringList addpeople::getList()

{
    return selectedList;
   
}

@Dy3zz said in Connect closing dialog with a Qt List Widget:

addpeople* window=new addpeople(this);

You create a dialog each time -> memory leak !

for the signals, just look at the doc:

Signals

void accepted()
void finished(int result)
void rejected()

and there are complete examples:

A modal dialog:
 void EditorWindow::countWords()
 {
     WordCountDialog dialog(this);
     dialog.setWordCount(document().wordCount());
     dialog.exec();
 }
A modeless dialog:
 void EditorWindow::find()
 {
     if (!findDialog) {
         findDialog = new FindDialog(this);
         connect(findDialog, SIGNAL(findNext()), this, SLOT(findNext()));
     }

     findDialog->show();
     findDialog->raise();
     findDialog->activateWindow();
 }

@mpergand It worked for me. I did this:

void home::on_AddPeopleBut_clicked()
{
     addpeople dialog(this);
     dialog.exec();
     QStringList a;
     a=dialog.getList();
     qDebug() << a[0];
}

I printed the first element to test . it worked perfectly. Thanks!!
