Member Function Documentation

◆ AllArchived()

virtual status_t BAbstractSpinner::AllArchived ( BMessage into) const
protectedvirtual

Hook method called when all views have been archived.

Since
BeOS R3

Reimplemented from BView.

◆ AllUnarchived()

virtual status_t BAbstractSpinner::AllUnarchived ( const BMessage from)
protectedvirtual

Hook method called when all views have been unarchived.

Since
BeOS R3

Reimplemented from BView.

◆ Archive()

virtual status_t BAbstractSpinner::Archive ( BMessage data,
bool  deep = true 
) const
virtual

Archives the control into data.

Parameters
dataThe target data that the data will go into.
deepWhether or not to recursively data child views.
Return values
B_OKThe data operation was successful.
B_BAD_VALUENULL data message.
B_ERRORThe archive operation failed.
See also
BArchivable::Archive()
Since
BeOS R3

Reimplemented from BControl.

◆ AttachedToWindow()

virtual void BAbstractSpinner::AttachedToWindow ( )
virtual

Hook method called when the control is attached to a window.

This method overrides BView::AttachedToWindow() setting the low color and view color of the BControl so that it matches the view color of the control's parent view. It also makes the attached window the default target for Invoke() as long as another target has not already been set.

See also
BView::AttachedToWindow()
Invoke()
BInvoker::SetTarget()
Since
BeOS R3

Reimplemented from BControl.

◆ DoLayout()

virtual void BAbstractSpinner::DoLayout ( )
protectedvirtual

Layout view within the layout context.

Remarks
This is only meaningful if the view is part of a BLayout.
Since
Haiku R1

Reimplemented from BView.

◆ Draw()

virtual void BAbstractSpinner::Draw ( BRect  updateRect)
virtual

Draws the area of the view that intersects updateRect.

Derived classes should override this method to draw their view.

Remarks
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.

◆ FrameResized()

virtual void BAbstractSpinner::FrameResized ( float  newWidth,
float  newHeight 
)
virtual

Hook method called when the view is resized.

Parameters
newWidthThe new width of the view.
newHeightThe new height of the view.
Since
BeOS R3

Reimplemented from BView.

◆ GetSupportedSuites()

virtual status_t BAbstractSpinner::GetSupportedSuites ( BMessage message)
virtual

Report the suites of messages this control understands.

Adds the string "suite/vnd.Be-control" to the message.

Since
BeOS R3

Reimplemented from BControl.

◆ LayoutInvalidated()

virtual void BAbstractSpinner::LayoutInvalidated ( bool  descendants)
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 BAbstractSpinner::MakeFocus ( bool  focus = true)
virtual

Gives or removes focus from the control.

BControl::MakeFocus() overrides BView::MakeFocus() to call Draw() when the focus changes. Derived classes generally don't have to re-implement MakeFocus().

IsFocusChanging() returns true when Draw() is called from this method.

Parameters
focustrue to set focus, false to remove it.
See also
BView::MakeFocus()
IsFocusChanging()
Since
BeOS R3

Reimplemented from BControl.

Remarks
This is only meaningful if the view is part of a BLayout.
Returns
The maximum size of the view as a BSize.
See also
BAbstractLayout::MaxSize()
Since
Haiku R1

Reimplemented from BView.

virtual

Handle message received by the associated looper.

Parameters
messageThe message received by the associated looper.
See also
BHandler::MessageReceived()
Since
BeOS R3

◆ ResolveSpecifier()

virtual BHandler* BAbstractSpinner::ResolveSpecifier ( BMessage message,
int32  index,
BMessage specifier,
int32  what,
const char *  property 
)
virtual

Determine the proper handler for a scripting message.

Parameters
messageThe scripting message to determine the handler.

enabledIf true enables the control, if false, disables it.

BeOS R3

Reimplemented from BControl.
