The QStyle class is an abstract base class that encapsulates the look and feel of a GUI. 34 public functions inherited from QObject.SubElementRect(QStyle::SubElement element, const QStyleOption * option, const QWidget * widget = nullptr) const = 0 SubControlRect(QStyle::ComplexControl control, const QStyleOptionComplex * option, QStyle::SubControl subControl, const QWidget * widget = nullptr) const = 0 StyleHint(QStyle::StyleHint hint, const QStyleOption * option = nullptr, const QWidget * widget = nullptr, QStyleHintReturn * returnData = nullptr) const = 0 StandardIcon(QStyle::StandardPixmap standardIcon, const QStyleOption * option =.

GeneratedIconPixmap(QIcon::Mode iconMode, const QPixmap & pixmap, const QStyleOption * option) const = 0 I think this is because the parent is NULL, so the dock widget doesn't know where it should re-attach on drag'n'drop.ComplexControl ĬombinedLayoutSpacing(QSizePolicy::ControlTypes controls1, QSizePolicy::ControlTypes controls2, Qt::Orientation orientation, QStyleOption * option = nullptr, QWidget * widget = nullptr) constĭrawComplexControl(QStyle::ComplexControl control, const QStyleOptionComplex * option, QPainter * painter, const QWidget * widget = nullptr) const = 0ĭrawControl(QStyle::ControlElement element, const QStyleOption * option, QPainter * painter, const QWidget * widget = nullptr) const = 0ĭrawItemPixmap(QPainter * painter, const QRect & rectangle, int alignment, const QPixmap & pixmap) constĭrawItemText(QPainter * painter, const QRect & rectangle, int alignment, const QPalette & palette, bool enabled, const QString & text, QPalette::ColorRole textRole = QPalette::NoRole) constĭrawPrimitive(QStyle::PrimitiveElement element, const QStyleOption * option, QPainter * painter, const QWidget * widget = nullptr) const = 0 reparent the dock widget to previous parent when it is re-attached from main windowīut there is still some problems : the user can't use drag'n'drop anymore to re-attach the dock to the main window.reparent the dock widget to NULL when it is detached from main window.

Now I want to make the dock widget behave like a 'top level' widget : not always on top of the main window and appears in taskbar. This works well (at least on Windows, which is my target) and display a 'maximize' button in the title bar. 'setWindowFlags' hides the widget, show it again SetWindowFlags(Qt::Dialog|Qt::CustomizeWindowHint|Qt::WindowTitleHint|Qt::WindowMaximizeButtonHint|Qt::WindowCloseButtonHint) The 'topLevelChanged' signal is connected to this member slot : void MyDockWidget::updateWindowFlags(bool topLevel) I use a subclass of QDockWidget with a little trick.
