An editor can be in principle any QWidget, which you want to use to display the current |
|
565
|
|
|
(model-)data. Therefore the editor is also a container, which handles the passed entries |
|
566
|
|
|
from the user interface and should save the data in the model object of the QTableWidget. |
|
567
|
|
|
|
|
568
|
|
|
Do not save the created editor as a class variable! This consumes a lot of unneeded memory. |
|
569
|
|
|
It is way better to create an editor if it is needed. The inherent function closeEditor() |
|
570
|
|
|
of QStyledItemDelegate takes care of closing and destroying the editor for you, if it is not |
|
571
|
|
|
needed any longer. |
