Standard notifications or alert styles in Symbian (Qt/S60)?
I'm building a an application using Qt on the Symbian/S60 platform and I was wondering if there was a standard notification window that I could use to pass messages to users. Using other platforms as examples, I'm looking for something equivalent to Javascript's alert() method or Cocoa's NSRunAlert* methods.
If there is not a native Symbian/S开发者_Python百科60 equivalent, is there something in the Qt space that I should be looking at? QMessageBox didn't seem to work as I might expect.
Apparently there is not a way to access the native notification windows from Qt proper. I did find the following:
//Create warning message box
QMessageBox::warning(0,"Warning", "Warning message text");
//Create information message box
QMessageBox::information(0, "Information", "Information message text");
//Create critical message box
QMessageBox::critical(0, "Critical", "Critical message text");
Still not what I'm looking for, but it will have to do.

You can use RNotifier class from any Symbian code (and from Qt too). This class can show notifications even from window-less programs, like Symbian servers. It is simple to use:
RNotifier notifier;
User::LeaveIfError(notifier.Connect());
TInt buttonVal;
TRequestStatus lStatus;
notifier.Notify(_L("First line of notification"), _L("Second line of notification"), _L("Left button text"), _L("Right button text"), buttonVal, lStatus);
User::WaitForRequest(lStatus);
notifier.Close();
After User::WaitForRequest(lStatus) completes you can inspect value of buttonVal to know which button was pressed. It is set to: 0, if the left button is selected; 1, if the right button is selected.
Hope this helps.
