Maximum duration for a script

[clouis]

What is the maximum duration a script can run before Qt decides that it has hung up and shows the message - "The script on this page appears to have a problem. Do you want to stop the script?"

[clouis]

How do I overcome this problem? Any help will be greatly appreciated!!!

Hi,

I am also new at this forum and not an expert on QT, and i will also appreciate some people to help and answer the questions. But it is not the case !!

For your question i have seen following :

./qt/src/3rdparty/webkit/Source/WebKit/qt/Api/qwebpage.cpp

/*!
\fn bool QWebPage::shouldInterruptJavaScript()
\since 4.6
This function is called when a JavaScript program is running for a long period of time.

If the user wanted to stop the JavaScript the implementation should return true; otherwise false.

The default implementation executes the query using QMessageBox::information with QMessageBox::Yes and QMessageBox::No buttons.

\warning Because of binary compatibility constraints, this function is not virtual. If you want to
provide your own implementation in a QWebPage subclass, reimplement the shouldInterruptJavaScript()
slot in your subclass instead. QtWebKit will dynamically detect the slot and call it.

/
bool QWebPage::shouldInterruptJavaScript()
{
#ifdef QT_NO_MESSAGEBOX
return false;
#else
QWidget parent = (d->client) ? d->client->ownerWidget() : 0;
return QMessageBox::Yes == QMessageBox::information(parent, tr("JavaScript Problem - %1").arg(mainFrame()->url().host()), tr("The script on this page appears to have a problem. Do you want to stop the script?"), QMessageBox::Yes, QMessageBox::No);
#endif
}

So i guess you can deactivate this dialog box by using :
QT_NO_MESSAGEBOX
