Is there any way to keep the information in a PtList widget after the parent window is closed and the PtList widget is destroyed?
|
| Solution |
After the widget has been destroyed, it does not exist. There is no way to keep information in a widget that does not exist.
In order to keep the list in the widget, the widget has to be prevented from being destroyed. For example, unrealizing it and re-parent it to the main window, and then re-parent it back when the dialog gets created again. But it is a better way to have a copy of the list in a separate array. |
