QFileDialog hides the extension ,creates problem.

[Rahul Das]

Hi,

I am using QFileDialog::getSaveFileName to save a file.
On the Dialog window, it shows the file name with out extension.
The file name of QFileDialog is set using QFileInfo::fileName () , and the filter by QFileInfo::completeSuffix ().

This works well with out any trouble if i dont change file name. if i change the file name on QFileDialog window , it saves with out extension!
Could any one please suggest me where i went wrong or a way to do this better ? All i want to do is, to save a file with any name but the extension shouldn't be changed with user interaction.
