void QWidget::show()

Shows the widget and its child widgets. This is equivalent to calling showFullScreen(), showMaximized(), or setVisible(true), depending on the platform's default behavior for the window flags.

void QWidget::showNormal()

Restores the widget after it has been maximized or minimized. Calling this function only affects windows.

void QWidget::raise()

Raises this widget to the top of the parent widget's stack. After this call the widget will be visually in front of any overlapping sibling widgets. Note: When using activateWindow(), you can call this function to ensure that the window is stacked on top.

void QWidget::activateWindow()

Sets the top-level widget containing this widget to be the active window. An active window is a visible top-level window that has the keyboard input focus. This function performs the same operation as clicking the mouse on the title bar of a top-level window. On X11, the result depends on the Window Manager. If you want to ensure that the window is stacked on top as well you should also call raise(). Note that the window must be visible, otherwise activateWindow() has no effect. On Windows, if you are calling this when the application is not currently the active one then it will not make it the active window. It will change the color of the taskbar entry to indicate that the window has changed in some way. This is because Microsoft does not allow an application to interrupt what the user is currently doing in another application.
