Checking that value of ui elements has been changed.

[rohitkk]

Hi All,

Is there any way to check that the ui elements(line edit,combo box,etc.) of the dialog has been changed.
What I want is to show a message to the user if he changes the value of any single ui element, saying that details have been partially filled.
What i can do is use connect for each ui element & based on the value changed of each element i am setting a boolean flag & at the time of close event i am checking that boolean flag.
But Its quite complicate to check it for each widget.
Is there any easier way.
Code that I am using for single ui element is,

connect(ui->leAge,SIGNAL(textChanged(QString)),this,SLOT(functChanged())); //In Constructor
 
void DemoDialog::functChanged()   //Will be called if value of line edit (ui->leAge) is changed
{
        flag=true;
}
 
void DemoDialog::closeEvent(QCloseEvent *event)
{
    if (flag) {
        if (QMessageBox::warning(this,"Close","Do you want to close?",QMessageBox::Yes|QMessageBox::No)==QMessageBox::Yes) {
            this->close();
        }
}

connect(ui->leAge,SIGNAL(textChanged(QString)),this,SLOT(functChanged())); //In Constructor

void DemoDialog::functChanged()   //Will be called if value of line edit (ui->leAge) is changed
{
        flag=true;
}

void DemoDialog::closeEvent(QCloseEvent *event)
{
    if (flag) {
        if (QMessageBox::warning(this,"Close","Do you want to close?",QMessageBox::Yes|QMessageBox::No)==QMessageBox::Yes) {
            this->close();
        }
}
