Detailed Description

Container class.

Library: ilvadvgdt
The IlvViewFrame class defines a special container that encapsulates a client view.

It adds a title bar composed of an icon, a label, and several buttons to the client view. The client view is added to the view frame by creating it as a child view of the view frame.

A frame can be in one of the three following states: normal, maximized, or minimized.

Example of an Application Using IlvViewFrame Objects

IlvDesktopManager.

Member Enumeration Documentation

§ IlvFrameState

This enumeration defines the various states that IlvViewFrame objects can take.

See also
IlvViewFrame::getCurrentState().
Enumerator
IlvFrameNormalState 

The default state for a view frame. The client view is visible, and can be resized by dragging the view frame border.

See also
restoreFrame().
IlvFrameMinimizedState 

In this state, only the title bar of the view frame is visible

See also
minimizeFrame().
IlvFrameMaximizedState 

In this state, the view frame occupies the entire desktop view and hides any other view frame.

See also
maximizeFrame().

Constructor & Destructor Documentation

§ IlvViewFrame()

IlvViewFrame::IlvViewFrame ( IlvView parent,
const char *  title,
const IlvRect size,
IlBoolean  visible = IlTrue 
)

Initializes a new IlvViewFrame instance.

Initializes a new instance of the class IlvViewFrame as a child view of parent.

Parameters
parentThe parent view of the view frame.
titleThe view frame title. This title is displayed in the title bar of the view frame.
sizeThe size and position of the view frame.
visibleSpecifies whether the view frame should be visible.
Note
The parent view of an IlvViewFrame must be linked to an IlvDesktopManager object. If this is not the case, a desktop manager is automatically created by this constructor.

Member Function Documentation

§ closeFrame()

virtual void IlvViewFrame::closeFrame ( )
virtual

Is called when the user closes the view frame.

The default implementation calls the destroy callbacks associated with the frame and its client view. To handle the destruction of a view frame you can either override this method in your own subclass of IlvViewFrame, or use a destroy callback.

See also
IlvView::setDestroyCallback().

§ getClient()

IlvView* IlvViewFrame::getClient ( ) const

Returns the client view managed by the view frame.

Returns
The client view managed by the view frame, or 0 if there is none.

§ getClientBBox()

virtual void IlvViewFrame::getClientBBox ( IlvRect bbox) const
virtual

Returns the bounding box of the client view managed by the view frame.

Parameters
bboxThe returned bounding box of the client view.

§ getCurrentState()

int IlvViewFrame::getCurrentState ( ) const

The current frame state.

Returns
The current frame state. The valid returned values are defined by the IlvFrameState enumeration.
See also
IlvFrameState, maximizeFrame(), minimizeFrame(), restoreFrame().

§ getDesktopManager()

IlvDesktopManager* IlvViewFrame::getDesktopManager ( ) const

Returns the desktop manager that handles the frame.

Returns
The desktop manager that handles this frame.
See also
IlvDesktopManager.

§ getIcon()

IlvBitmap* IlvViewFrame::getIcon ( ) const

Returns the bitmap associated with the view frame.

The bitmap is displayed in the title bar of the view frame.

Returns
The bitmap of the frame.
See also
setIcon(), IlvBitmap.

§ getMenu()

IlvPopupMenu* IlvViewFrame::getMenu ( ) const

Returns the IlvPopupMenu object attached to the frame.

The pop-up menu is displayed when the user clicks the icon of the title bar. This menu contains predefined items for changing the frame state. You can modify this menu by adding or removing items.

Returns
The IlvPopupMenu object used by the frame.
See also
showMenu().

§ getMinHeight()

IlvDim IlvViewFrame::getMinHeight ( ) const

Returns the minimum height of the view frame.

The view frame cannot be resized to a size smaller than its minimum dimensions.

Returns
The minimum height of this view frame.
See also
setMinHeight(), getMinWidth().

§ getMinWidth()

IlvDim IlvViewFrame::getMinWidth ( ) const

Returns the minimum width of the view frame.

The view frame cannot be resized to a size smaller than its minimum dimensions.

Returns
The minimum width of this view frame.
See also
setMinWidth(), getMinHeight().

§ getTitle()

const char* IlvViewFrame::getTitle ( ) const

Returns the title of the view frame.

The title is displayed in the title bar of the view frame.

Returns
The title of the frame.
See also
setTitle().

§ getTitleBarBBox()

void IlvViewFrame::getTitleBarBBox ( IlvRect bbox) const

Returns the bounding box of the title bar of the view frame.

Parameters
bboxThe returned bounding box of the title bar.

§ IsShowingContentsWhileDragging()

static IlBoolean IlvViewFrame::IsShowingContentsWhileDragging ( )
static

Indicates whether the entire contents of a view frame is drawn when the view frame is moved or resized.

If this method returns IlFalse, only the ghost image of the view frame is drawn when the view frame is moved or resized.

Returns
IlTrue if the entire contents of a view frame is drawn when the view frame is moved or resized and IlFalse otherwise.

§ maximizeFrame()

virtual void IlvViewFrame::maximizeFrame ( )
virtual

Is called to maximize the frame to make it fit the view of the desktop manager.

See also
IlvFrameState, restoreFrame(), minimizeFrame(), IlvDesktopManager::isMaximizing().

§ minimizeFrame()

virtual void IlvViewFrame::minimizeFrame ( )
virtual

Is called to minimize the frame so that only its title bar is visible.

See also
IlvFrameState, restoreFrame(), maximizeFrame().

§ registerClientView()

void IlvViewFrame::registerClientView ( IlvView view) const

Registers the specified view as a client view of this view frame.

A client view will forward some events to its view frame. This method is automatically called on the main client view of the view frame. You need to call this method if your main client view contains subviews. In this case, call this method giving each subview as parameter.

Parameters
viewThe view to be registered as a client view.
