Constructor & Destructor Documentation

§ IlvMenuBar() [1/4]

IlvMenuBar::IlvMenuBar ( IlvDisplay display,
const IlvPoint point,
const char *const *  labels = 0,
IlUShort  count = 0,
IlUShort  thickness = IlvDefaultGadgetThickness,
IlvPalette palette = 0 
)

Constructor.

Initializes a new instance of the IlvMenuBar class. The size of the object is computed by calling the IlvGadget::fitToContents() method. If you want the menu bar to have a specific size, use a constructor that takes an IlvRect reference instead of an IlvPoint object as parameter. The labels are copied.

Parameters
displayThe connection to the display.
pointThe position of the menu bar.
labelsAn array of predefined labels.
countThe number of elements in the labels array.
thicknessThe thickness of the menu bar.
paletteThe palette used to draw the menu bar.

§ IlvMenuBar() [2/4]

IlvMenuBar::IlvMenuBar ( IlvDisplay display,
const IlvRect rect,
const char *const *  labels = 0,
IlUShort  count = 0,
IlUShort  thickness = IlvDefaultGadgetThickness,
IlvPalette palette = 0 
)

Constructor.

Initializes a new instance of the IlvMenuBar class. The labels are copied.

Parameters
displayThe connection to the display.
rectThe size and position of the menu bar.
labelsAn array of predefined labels.
countThe number of elements in the labels array.
thicknessThe thickness of the menu bar.
paletteThe palette used to draw the menu bar.

§ IlvMenuBar() [3/4]

IlvMenuBar::IlvMenuBar ( IlvDisplay display,
const IlvPoint point,
IlvMenuItem items,
IlUShort  count,
IlUShort  thickness = IlvDefaultGadgetThickness,
IlvPalette palette = 0 
)

Constructor.

Initializes a new instance of the IlvMenuBar class. The size of the object is computed by calling the IlvGadget::fitToContents() method. If you want to give the menu bar a specific size, use a constructor that takes an IlvRect reference instead of an IlvPoint object as parameter.

Parameters
displayThe connection to the display.
pointThe position of the menu bar.
itemsAn array of predefined items. The items are copied.
countThe number of elements in the items array.
thicknessThe thickness of the menu bar.
paletteThe palette used to draw the menu bar.

§ IlvMenuBar() [4/4]

IlvMenuBar::IlvMenuBar ( IlvDisplay display,
const IlvRect rect,
IlvMenuItem items,
IlUShort  count,
IlUShort  thickness = IlvDefaultGadgetThickness,
IlvPalette palette = 0 
)

Constructor.

Initializes a new instance of the IlvMenuBar class.

Parameters
displayThe display connection.
rectThe size and position of the menu bar.
itemsAn array of predefined items. The items are copied.
countThe number of elements in the items array.
thicknessThe thickness of the menu bar.
paletteThe palette used by the menu bar.

Member Function Documentation

§ drawGadgetItem()

virtual void IlvMenuBar::drawGadgetItem ( const IlvGadgetItem item,
IlvPort port,
const IlvRect rect,
const IlvTransformer t = 0,
const IlvRegion clip = 0 
) const
virtual

Draws a specific gadget item.

Redraws item in port at the location specified by rect using the clipping area clip. This method simply calls IlvGadgetItem::draw() using the item instance.

Parameters
itemThe item to be redrawn.
portThe destination drawing port.
rectThe bounding box of the item.
tThe transformer used to draw the item. Not used.
clipThe clipping area.
See also
IlvGadgetItem::draw().

Reimplemented from IlvAbstractBar.

§ internalBBox()

void IlvMenuBar::internalBBox ( IlvRect rect,
const IlvTransformer t = 0 
) const
virtual

Returns the internal bounding box of the bar.

Uses rect to return the internal bounding box of the bar when the object is computed with the transformer t. The internal bounding box delimits the area within which the bar items are drawn. You can override this member function in a subclass to change the internal bounding box.

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

Reimplemented from IlvAbstractBar.
