\ccDefinition
|
|
|
|
The standard toolbar includes the basic tools used for zooming and
|
|
translating in a \ccc{Qt_widget}.

\ccConstructor{Qt_widget_standard_toolbar(Qt_widget *w, QMainWindow

*mw , QWidget* parent, bool newline = true, const char* name =
|

|
|
{ This constructor creates a new toolbar, called \ccc{name}, in your
|
|
application, containing all the standard tools. The first parameter
|
|
\ccc{w} is a non-null pointer to the Qt\_widget object on which the
|
|
toolbar functionalities act. The second parameter \ccc{mw} is a
|
|
pointer to the \ccc{QMainWindow} that manages the toolbar. The later
|
|
is added to the top area of the \ccc{QMainWindow}, unless
|
|
\ccc{mw=0}. \ccc{mw}, \ccc{parent}, \ccc{newline}, \ccc{name} are
|
|
passed to the \ccc{QMainWindow} constructor (with first parameter
|
|
\ccc{label=''Qt_widget standard toolbar''}). }
|
|
|
|
\ccConstructor{Qt_widget_standard_toolbar(Qt_widget *w, QMainWindow
|
|
*parent = 0, const char* name = 0);}
|
|
{ Simplified version of the previous one. The \ccc{parent} is the
|
|
\ccc{QMainWindow} that manages the toolbar. }
|
|
|
|
\ccMethod{const QToolBar* toolbar();}{Deprecated: (in CGAL-2.4 the
|
|
standard toolbar was not derived from \ccc{QToolBar}) Returns a pointer to
|
|
the \ccc{QToolBar this} itself. }
|
|
|
|
\ccHeading{public slots:}
|
|
\ccMethod{void back();}{Goes back in the history list of the standard toolbar.}
|
|
\ccMethod{void forward();}{Goes forward in the history list of the
|

standard toolbar.}

\ccMethod{void clear_history();}{Clears the history list of the
