I have connected the "clicked" signal to a slot which checks the size of the QText Edit.

Since I used Qt Designer to make the dialog, it has a QDialog Button Box.

When the user presses OK, I need to make sure that the data in the QText Edit is valid.

If the size is adequate, I call "accept()" otherwise the slot just returns.

The problem is that the dialog disappears even when accept() is not called.

If I use the reject() function, the dialog still disappears.

The solution is to delete the default button box(with OK and Cancel) created by designer and to create your own.Regards How about a slot that validates contents of the dialog and enables/disables the button correspondingly?This slot would be connected to various content change signals of entry widgets in the dialog.It is usually a good idea to prevent insensible user actions. In case anyone searches this thread for a similar problem, I thought I'd send the resolution.It is not necessary to create one's own ok/cancel buttons, although that would probably work (I didn't try that).It is also not necessary to enable/disable the ok/cancel buttons, but that is a good idea (I didn't try that either).
