How to change or detach layout of Widget?(+ or using private function)

Mue22

first, i set the widget's layout,

ui->widget1->setLayout(layout1);
ui->widget2->setLayout(layout2);

but i want to change the layout of widget, according to condition.

ui->widget1->setLayout(layout2);
ui->widget2->setLayout(layout1);

they send the errormessage "~~already set the layout".

how can i solve this problem?

++
I find QWidget::takeLayout()
but it was private, so i can use this function :(..... plz give me the solution..

@Mue22 Use layout() to get the current layout and delete it. Then remove all the widgets added inside it. After that set new layout using setLayout().

i want to just change each layout....:(
i want to just detach the layout from widget, and reuse to another widget..
(if i use your solution, i can reuse layout1, 2... its correct?)
->(if i use your solution, i can't reuse layout1, 2... its correct?)

@Mue22 AFAIK to detach you will have to delete it and hence all the widgets inside it too. Then create new layout and then setLayout.

i can reuse layout1, 2... its correct?

No, since it is deleted.

i want to say that:

@Mue22 Yes you can't. Since detaching requires deleting, new layout must be created to use again.
