A general-purpose confirmation form. This can be used to obtain confirmation
|
||||
that the user wants to delete a list of items, for example.
|
||||
It is implemented as a QDialog containing:
|
||||
- a QListView to display the list of items (eg the items to be deleted)
|
||||
- a message which asks the user for confirmation
|
||||
- Yes and No buttons, with Yes being the default
|
||||
After instantiating a ConfirmationForm object the calling code must call exec() on the instance.
|
||||
This runs the Qt dialog, which returns the usual 0 (for No) or 1 (for Yes)
