QListWidget refreshing issue

[wladek]

Hey ouekah,

Good news! I believe i have found a hack for solving this.
I just had an idea and tried it out on my Mac. What I did was the following:
1. added a private slot in my header

private slots:
    void buttonWasPushed();
    void updateGroupBoxTitle();

private slots:
    void buttonWasPushed();
    void updateGroupBoxTitle();

To copy to clipboard, switch view to plain text mode 

2. In the already defined add function I do not call directly groupBox->setTitle(), but instead I use the QTimer:singleShot() static function:

void Form::add(const QString& item)
{
    ui->listWidget->addItem(item);
    QTimer::singleShot(0, this, SLOT(updateGroupBoxTitle()));
}

void Form::add(const QString& item)
{
    ui->listWidget->addItem(item);
    QTimer::singleShot(0, this, SLOT(updateGroupBoxTitle()));
}

To copy to clipboard, switch view to plain text mode 

.

Then, in the implementation of the updateGroupBoxTitle() slot i just set the title of the groupbox:

void Form::updateGroupBoxTitle()
{
	ui->groupBox->setTitle("Currently (" + QString::number(ui->listWidget->count()) + ")"); // updates QGroupBox title
}

void Form::updateGroupBoxTitle()
{
	ui->groupBox->setTitle("Currently (" + QString::number(ui->listWidget->count()) + ")"); // updates QGroupBox title
}

To copy to clipboard, switch view to plain text mode 

This works for me. I hope it will be functional for you also.
If it does work, do not ask me why .

Waiting for your feedback...
