How can i iterate through QListWidget items and work with each item?
- by Hossein
In CSharp its as simple as writting :
listBox1.Items.Add("Hello");
listBox1.Items.Add("There");
foreach (string item in listBox1.Items )
{
MessageBox.Show(item.ToString());
}
and i can easily add different objects to a list box and then retrieve them using foreach.
I tried the same approach in Qt 4.8.2 but it seems they are different.though they look very similar at first.I found that Qt supports foreach so i went on and tried
something like :
foreach(QListWidgetItem& item,ui->listWidget->items())
{
item.setTextColor(QColor::blue());
}
which failed clearly.It says the items() needs a parameter which confuses me.I am trying to iterate through the ListBox itself, so what does this mean?
I tried passing the ListBox object as the parameter itself this again failed too:
foreach(QListWidgetItem& item,ui->listWidget->items(ui->listWidget))
{
item.setTextColor(QColor::blue());
}
So here are my questions:
How can I iterate through a QListWidget items in Qt?
Can i store objects as items in QListWidgets like C#?
How can i convert an object in QListWidgets to string(C#s ToString counter part in Qt) ?
(suppose i want to use a QMessagBox instead of that setTextColor and want to print out all string items in the QlistWidget.)
