How to control the position of QDialog

Question

Hello Is there any easy way to open the qt dialogs in the same position as they were the last time the application was open ? i.e preserve position of dialogs between application sessions ? Under easy way I understand not to have manually write the window position in file ,and then read :) Thanks

Answer 1

You can use the QSettings class to achieve this. It's an abstraction class that allow your applications to store its settings in order to retrieve them at next launch.

Save settings:

QSettings settings("ValueName",  "Value");

Read settings:

QString v = settings.value("ValueName");

Answer 2

Use QSettings along with QWidget::restoreGeometry() and QWidget::saveGeometry().

Answer 3

Better to save dialog->pos(), dialog->size(), dialog->isMaximized(), cause dialog->saveGeometry() doesn't maximize the window.

QSettings is the preffered way to save configuration
