Detailed Description

Displays different kind of bullets.

Perhaps, in the future, Unicode characters are used for bullets, so this widget is not used anymore.

Member Function Documentation

void dw::Bullet::draw	(	core::View *	view,
		core::Rectangle *	area
	)

protectedvirtual

Area is given in widget coordinates.

Implements dw::core::Widget.

References dw::core::Widget::allocation, dw::core::Allocation::ascent, dw::core::View::drawArc(), dw::core::View::drawRectangle(), dw::core::style::StyleAttrs::font, dw::core::Widget::getStyle(), dw::core::style::LIST_STYLE_TYPE_CIRCLE, dw::core::style::LIST_STYLE_TYPE_DISC, dw::core::style::LIST_STYLE_TYPE_SQUARE, lout::misc::min(), dw::core::style::Color::SHADING_NORMAL, dw::core::Allocation::width, dw::core::Allocation::x, dw::core::style::Font::xHeight, and dw::core::Allocation::y.

core::Iterator * dw::Bullet::iterator	(	core::Content::Type	mask,
		bool	atEnd
	)

protectedvirtual

Return an iterator for this widget.

mask can narrow the types returned by the iterator, this can enhance performance quite much, e.g. when only searching for child widgets.

With atEnd == false, the iterator starts before the beginning, i.e. the first call of dw::core::Iterator::next will let the iterator point on the first piece of contents. Likewise, With atEnd == true, the iterator starts after the last piece of contents, call dw::core::Iterator::prev in this case.

Bug:: Not implemented.

Implements dw::core::Widget.

void dw::Bullet::sizeRequestImpl ( core::Requisition * requisition )

protectedvirtual

See Sizes of Dillo Widgets.

Implements dw::core::Widget.

References dw::core::Requisition::ascent, dw::core::Requisition::descent, dw::core::Widget::getStyle(), lout::misc::max(), and dw::core::Requisition::width.
