◆ BBox() [3/4]

BBox::BBox ( border_style  border,
BView child 
)

Constructs an anonymous BBox object with a defined border style and child view.

There can only be a single child view. This view can, however, act as a nesting container if you need to show more items inside the box.

Since
Haiku R1

◆ ~BBox()

BBox::~BBox ( )
virtual

Destructor method.

Calling the destructor will also free the memory used by the box's label if it has one.

Since
BeOS R3

◆ BBox() [4/4]

BBox::BBox ( BMessage archive)

Constructs a BBox object from an archive message.

This method is usually not called directly. If you want to build a BBox object from a message you should call Instantiate() which can handle errors properly.

If the archive deep, the BBox object will also unarchive each of its child views recursively.

Parameters
archiveThe archive message to restore from.

BeOS R3

Member Function Documentation

◆ AllAttached()

virtual void BBox::AllAttached ( )
virtual

Similar to AttachedToWindow() but this method is triggered after all child views have already been attached to a window.

Since
BeOS R3

Reimplemented from BView.

◆ AllDetached()

virtual void BBox::AllDetached ( )
virtual

Similar to AttachedToWindow() but this method is triggered after all child views have already been detached from a window.

Since
BeOS R3

Reimplemented from BView.

◆ Archive()

status_t BBox::Archive ( BMessage archive,
bool  deep = true 
) const
virtual

Archives the object into archive.

Parameters
archiveThe target archive that the data will go into.
deepWhether or not to recursively archive child views.
Return values
B_OKThe archive operation was successful.
B_BAD_VALUENULL archive message.
B_ERRORThe archive operation failed.

BArchivable::Archive()
Since
BeOS R3

Reimplemented from BView.

◆ AttachedToWindow()

void BBox::AttachedToWindow ( )
virtual

Hook method that is called when the object is attached to a window.

This method overrides BView::AttachedToWindow() to set the background color of the box to the background of its parent view.

If you are using the layout system, the BBox is also resized according to the layout of the parent view.

See also
BView::AttachedToWindow()
Since
BeOS R3

Reimplemented from BView.

◆ Border()

border_style BBox::Border ( ) const

Gets the current border_style.

Possible border_style values include:

  • B_PLAIN_BORDER A single 1-pixel line border.
  • B_FANCY_BORDER The default, beveled look.
  • B_NO_BORDER Used to make a borderless box.
Returns
The border_style of the box.
Since
BeOS R3

◆ DetachedFromWindow()

virtual void BBox::DetachedFromWindow ( )
virtual

Hook method called when the object is detached from a window.

Since
BeOS R3

Reimplemented from BView.

◆ DoLayout()

void BBox::DoLayout ( )
protectedvirtual

Lays out the box moving everything into its appropriate position.

This only works if the BBox object was constructed using the Layout API, i.e. it was created with one of the BRect-less constructors.

Once the size of the box is known from laying out its parent views, this method is called so the box can adjust the position and size of the label, eventually truncating the label text if there is not enough space. The exact border positions are also computed, then the child view is also laid out if its size constraints change.

Since
Haiku R1

Reimplemented from BView.

◆ Draw()

void BBox::Draw ( BRect  updateRect)
virtual

Draws the area of the box that intersects updateRect.

This is an hook method called by the Interface Kit, you don't have to call it yourself. If you need to forcefully redraw the view, consider calling Invalidate() instead.

Parameters
updateRectThe rectangular area to be drawn.
Since
BeOS R3

Reimplemented from BView.

◆ FrameMoved()

virtual void BBox::FrameMoved ( BPoint  newPosition)
virtual

Hook method called when the view is moved.

Parameters
newPositionThe point of the top left corner of the frame that the view has been moved to.
Since
BeOS R3

Reimplemented from BView.

◆ FrameResized()

void BBox::FrameResized ( float  width,
float  height 
)
virtual

Hook method that gets called when the BBox object is resized.

This method may be called either because the window in which the BBox object was resized, or because the window layout was otherwise altered.

This method recomputes the layout of the BBox (including label and contents) and makes it redraw as necessary.

Since
BeOS R3

Reimplemented from BView.

◆ GetPreferredSize()

void BBox::GetPreferredSize ( float *  _width,
float *  _height 
)
virtual

Fill out the preferred width and height of the box into the _width and _height parameters.

Note
Either the _width or _height parameter may be set to NULL if you only want to get the other one.

The size is computed from the child view sizes, unless it was explicitly set for the BBox (which can be done only if the BBox is configured to use the Layout API).

Parameters
[out]_widthPointer to a float to store the width of the view.
[out]_heightPointer to a float to store the height of the view.
Since
BeOS R3

Reimplemented from BView.

◆ GetSupportedSuites()

Gets the frame rectangle just inside the border of the box.

Warning
This method is not yet finalized.
Returns
A BRect set to the dimensions of the box's inside border.
Since
Haiku R1

◆ Instantiate()

static BArchivable * BBox::Instantiate ( BMessage archive)
static

Creates a new object from an archive.

If the message is a valid object then the instance created from the passed in archive will be returned. Otherwise this method will return NULL.

Parameters
archiveThe archive message.
Returns
An instance of the object if archive is valid or NULL.
See also
BArchivable::Instantiate()
Since
BeOS R3

◆ Label()

const char * BBox::Label ( ) const

Gets the text of the box's label.

This only works if the label is set as text. If you set the label to a BView, you have to get the text by other means, likely starting with LabelView.

Returns
The label text of the BBox if the box has a text label or NULL otherwise.
Since
BeOS R3

◆ LabelView()

BView * BBox::LabelView ( ) const

Gets the BView representing the label.

Returns
a pointer to a BView object.
Since
BeOS R4

◆ LayoutInvalidated()

virtual void BBox::LayoutInvalidated ( bool  descendants = false)
protectedvirtual

Hook method called when the layout is invalidated.

Parameters
descendantsWhether or not child views have also been invalidated.
Since
Haiku R1

Reimplemented from BView.

◆ MakeFocus()

virtual void BBox::MakeFocus ( bool  focus = true)
virtual

Makes the view the current focus view of the window or gives up being the window's focus view.

The focus view handles selections and KeyDown events when the the attached window is active. There can be only one focus view at a time per window.

When called with focus set to true this method first calls MakeFocus() on the previously focused view with focus set to false.

The focus doesn't automatically change when MouseDown() is called so calling MakeFocus() is the only way to make a view the focus view of a window. Classes derived from BView that can display the current selection, or that can accept pasted data should call MakeFocus() in their MouseDown() method to update the focus view of the window on click.

If the view isn't attached to a window this method has no effect.

Parameters
focustrue to set focus, false to remove it.
Since
BeOS R3

Since
BeOS R3

Reimplemented from BView.

◆ MinSize()

BSize BBox::MinSize ( )
