Detailed Description

Gadget class.

Library: ilvgadgt

IlvAbstractBar is an abstract class used to manage a list of menu items. It lets you choose the bar orientation and force the bar to display all the items it contains. This class is the base class for IlvToolBar and IlvMenuBar.

See also
IlvMenuBar, IlvToolBar, IlvMenuItem, IlvAbstractBarPane

Accessors

Accessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods IlvValueInterface::queryValue(), IlvValueInterface::queryValues(), IlvValueInterface::changeValue(), IlvValueInterface::changeValues(). This class inherits the accessors of its superclass IlvAbstractMenu and adds the following ones:

Name Type Equivalent methods
flushRight Boolean isFlushingRight(), setFlushingRight()
constrained Boolean useConstraintMode(), setConstraintMode()
orientation Direction getOrientation(), setOrientation()
itemsWidth UInt getDefaultItemSize(), setDefaultItemSize()
itemsHeight UInt getDefaultItemSize(), setDefaultItemSize()
spacing UInt getSpacing(), setSpacing()

§ getDefaultItemSize()

void IlvAbstractBar::getDefaultItemSize ( IlvDim width,
IlvDim height 
) const

Returns the default item size.

Sets width and height to the default item width and item height, if all the items have the same size.

See also
setDefaultItemSize

§ getOrientation()

virtual IlvDirection IlvAbstractBar::getOrientation ( ) const
virtual

Returns the orientation of the bar.

If the orientation of the bar is set to IlvVertical, the items are drawn from top to bottom. If it is set to IlvHorizontal, items are drawn from left to right.

const IlvTransformer t = 0 
) const
virtual

Returns the internal bounding box of the bar.

rectThe internal bounding box of the bar.
tThe transformer used to compute the internal bounding box.

Implements IlvAbstractMenu.

Reimplemented in IlvToolBar, and IlvMenuBar.

IlvRect bbox,
const IlvTransformer t = 0 
) const
virtual

Returns the bounding box of a menu item in the menu.

Parameters
indexThe index of the item.
bboxThe returned menu item's bounding box.
tThe transformer used to compute the item's bounding box.

Implements IlvAbstractMenu.

§ orientationChanged()

virtual void IlvAbstractBar::orientationChanged ( )
virtual

Is called when the bar orientation has changed.
