Resizing all the widgets when maximizing the window.

[Lingesh]

Hi everyone, may i know how to resize all the widgets when when launch the app. Currently my UI has multiple frames with hide and show function

Call QWidget::resize(), QWidget::showMaximized(), or QWidget::setGeometry() on each top-level widget as required. The layout within the top-level widgets should look after all the contained widgets.
You might find QWidget::saveGeometry() and QWidget::restoreGeometry() along with QSettings to keep sizes between runs.
