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

containerSizeChangedForChildren()

void dw::Bullet::containerSizeChangedForChildren ( )

protectedvirtual

Reimplemented from dw::core::Widget.

Definition at line 52 of file bullet.cc.

References DBG_OBJ_ENTER0, and DBG_OBJ_LEAVE.

draw()

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

protectedvirtual

Area is given in widget coordinates.

Implements dw::core::Widget.

Definition at line 59 of file bullet.cc.

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.

getExtremesSimpl()

void dw::Bullet::getExtremesSimpl ( core::Extremes *  extremes )

protectedvirtual

Simple variant, to be implemented by widgets with extremes not depending on positions.

Reimplemented from dw::core::Widget.

Definition at line 45 of file bullet.cc.

References dw::core::Extremes::adjustmentWidth, dw::core::Widget::extremes, dw::core::Widget::getStyle(), lout::misc::max(), dw::core::Extremes::maxWidth, dw::core::Extremes::maxWidthIntrinsic, dw::core::Extremes::minWidth, and dw::core::Extremes::minWidthIntrinsic.

iterator()

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.

Definition at line 85 of file bullet.cc.

sizeRequestSimpl()

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

protectedvirtual

Simple variant, to be implemented by widgets with sizes not depending on positions.

Reimplemented from dw::core::Widget.

Definition at line 38 of file bullet.cc.

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