|
58 \brief The Q3SqlEditorFactory class is used to create the editors |
|
59 used by Q3DataTable and Q3SqlForm. |
|
60 |
|
61 \compat |
|
62 |
|
63 Q3SqlEditorFactory is used by Q3DataTable and Q3SqlForm to |
|
64 automatically create appropriate editors for a given QSqlField. |
|
65 For example if the field is a QVariant::String a QLineEdit would |
|
66 be the default editor, whereas a QVariant::Int's default editor |
|
67 would be a QSpinBox. |
|
68 |
|
69 If you want to create different editors for fields with the same |
|
70 data type, subclass Q3SqlEditorFactory and reimplement the |
|
71 createEditor() function. |
|
