Detailed Description

The QFrame class is the base class of widgets that can have a frame.

QMenu uses this to "raise" the menu above the surrounding screen. QProgressBar has a "sunken" look. QLabel has a flat look. The frames of widgets like these can be changed.

QLabel label(...);
label.setFrameStyle(QFrame::Panel | QFrame::Raised);
label.setLineWidth(2);
QProgressBar pbar(...);
label.setFrameStyle(QFrame::NoFrame);

The QFrame class can also be used directly for creating simple placeholder frames without any contents.

The frame style is specified by a frame shape and a shadow style that is used to visually separate the frame from surrounding widgets. These properties can be set together using the setFrameStyle() function and read with frameStyle().

The frame shapes are NoFrame , Box , Panel , StyledPanel , HLine and VLine ; the shadow styles are Plain , Raised and Sunken .

A frame widget has three attributes that describe the thickness of the border: lineWidth , midLineWidth , and frameWidth .

The margin between the frame and the contents of the frame can be customized with the QWidget::setContentsMargins() function.

This table shows some of the combinations of styles and line widths:

Enumerations

◆ Shadow

This enum type defines the types of shadow that are used to give a 3D effect to frames.

  • Plain the frame and contents appear level with the surroundings; draws using the palette QPalette::WindowText color (without any 3D effect)
  • Raised the frame and contents appear raised; draws a 3D raised line using the light and dark colors of the current color group
  • Sunken the frame and contents appear sunken; draws a 3D sunken line using the light and dark colors of the current color group

Shadow interacts with QFrame::Shape, the lineWidth() and the midLineWidth(). See the picture of the frames in the main class documentation.

Sunken 

Definition at line 96 of file qframe.h.

96  {
97  Plain = 0x0010, // plain line
98  Raised = 0x0020, // raised shadow effect
99  Sunken = 0x0030 // sunken shadow effect
100  };

◆ Shape

This enum type defines the shapes of frame available.

  • NoFrame QFrame draws nothing
  • Box QFrame draws a box around its contents
  • Panel QFrame draws a panel to make the contents appear raised or sunken
  • StyledPanel draws a rectangular panel with a look that depends on the current GUI style. It can be raised or sunken.
  • HLine QFrame draws a horizontal line that frames nothing (useful as separator)
  • VLine QFrame draws a vertical line that frames nothing (useful as separator)
  • WinPanel draws a rectangular panel that can be raised or sunken like those in Windows 2000. Specifying this shape sets the line width to 2 pixels. WinPanel is provided for compatibility. For GUI style independence we recommend using StyledPanel instead.
  • GroupBoxPanel
  • ToolBarPanel
  • MenuBarPanel
  • PopupPanel
  • LineEditPanel
  • TabWidgetPanel

When it does not call QStyle, Shape interacts with QFrame::Shadow, the lineWidth() and the midLineWidth() to create the total result. See the picture of the frames in the main class documentation.

95  };

◆ StyleMask

This enum defines two constants that can be used to extract the two components of frameStyle():

  • MShadow
  • MShape

Normally, you don't need to use these, since frameShadow() and frameShape() already extract the Shadow and the Shape parts of frameStyle().

◆ paintEvent()

void QFrame::paintEvent ( QPaintEvent event)
protectedvirtual

This event handler can be reimplemented in a subclass to receive paint events passed in event.

A paint event is a request to repaint all or part of a widget. It can happen for one of the following reasons:

  • repaint() or update() was invoked,
  • the widget was obscured and has now been uncovered, or
  • many other reasons.

Many widgets can simply repaint their entire surface when asked to, but some slow widgets need to optimize by painting only the requested region: QPaintEvent::region(). This speed optimization does not change the result, as painting is clipped to that region during event processing. QListView and QTableView do this, for example.

Qt also tries to speed up painting by merging multiple paint events into one. When update() is called several times or the window system sends several paint events, Qt merges these events into one event with a larger region (see QRegion::united()). The repaint() function does not permit this optimization, so we suggest using update() whenever possible.

When the paint event occurs, the update region has normally been erased, so you are painting on the widget's background.

The background can be set using setBackgroundRole() and setPalette().

Since Qt 4.0, QWidget automatically double-buffers its painting, so there is no need to write double-buffering code in paintEvent() to avoid flicker.

Note for the X11 platform: It is possible to toggle global double buffering by calling qt_x11_set_global_double_buffer(). For example,

Note
Generally, you should refrain from calling update() or repaint() inside a paintEvent(). For example, calling update() or repaint() on children inside a paintevent() results in undefined behavior; the child may or may not get a paint event.
Warning
If you are using a custom paint engine without Qt's backingstore, Qt::WA_PaintOnScreen must be set. Otherwise, QWidget::paintEngine() will never be called; the backingstore will be used instead.

The frame shapes are given in QFrame::Shape and the shadow styles in QFrame::Shadow.

If a mid-line width greater than 0 is specified, an additional line is drawn for Raised or Sunken Box , HLine , and VLine frames. The mid-color of the current color group is used for drawing middle lines.

The frame's rectangle is the rectangle the frame is drawn in. By default, this is the entire widget. Setting the rectangle does does not cause a widget update. The frame rectangle is automatically adjusted when the widget changes size.

If you set the rectangle to a null rectangle (for example, QRect(0, 0, 0, 0)), then the resulting frame rectangle is equivalent to the widget rectangle.
