The sequence is: - User enters text. - User presses enter, tries to leave the edit widget or t*editwidget.checkvalue() will be called or a button will be clicked (there are some more activities which trigger checkvalue()). - T*editwidget tries to convert the entered text to type of the value property. - If the conversion fails it shows an error message. - If the conversion succeeds onsetvalue will be called with the converted value as var parameter, t*editwidget.value still has the old value. - If onsetvalue returns accept = false further processing stops. - If onsetvalue returns accept = true the new value which possibly has been modified by onsetvalue will be stored in t*editwidget.value property. - ondataentered event will be called.
