Detailed Description
An abstract base class for icons to be drawn on a map.
Member Function Documentation
| virtual const TBitmap* CartoType::CIcon::Bitmap | ( | ) | const [inline, virtual] |
Return a pointer to the bitmap of this icon if one exists, or null if there is none.
Reimplemented in CartoType::CBitmapIcon.
| virtual class CBitmapIcon* CartoType::CIcon::BitmapIcon | ( | ) | [inline, virtual] |
Return a pointer to a CBitmapIcon if this is an object of that class, or null if not.
Reimplemented in CartoType::CBitmapIcon.
| virtual TResult CartoType::CIcon::Draw | ( | CGraphicsContext & | aGc, |
| const TPoint & | aTopLeft | ||
| ) | const [pure virtual] |
Draw the icon with its top left (not its hotspot) at aTopLeft.
Implemented in CartoType::CBoxIcon, and CartoType::CBitmapIcon.
| virtual void CartoType::CIcon::GetBounds | ( | TRect & | aBounds | ) | const [pure virtual] |
Get the bounds of the icon relative to its hotspot. The hotspot is the point, relative to the top left corner of the icon, that should be made to coincide with the point of interest marked by the icon.
Implemented in CartoType::CBoxIcon, and CartoType::CBitmapIcon.
| virtual void CartoType::CIcon::GetLabelPos | ( | TPoint & | aLabelPos | ) | const [inline, virtual] |
Get the position for label text (center of baseline) relative to the hot spot.
Reimplemented in CartoType::CBitmapIcon.
| virtual int32 CartoType::CIcon::LabelMaxLength | ( | ) | const [inline, virtual] |
Get the maximum length in pixels for label text.
Reimplemented in CartoType::CBitmapIcon.
| CT_EXPORT int32 CIcon::MaxDistanceFromOrigin | ( | ) | const [virtual] |
Return a value in 64ths of pixels that is at least the maximum distance from the origin of any part of the icon.
Reimplemented in CartoType::CBitmapIcon.
| virtual TResult CartoType::CIcon::Test | ( | CLabelGraphicsContext & | aGc, |
| const TPoint & | aTopLeft, | ||
| bool | aCanOverlapEdge | ||
| ) | const [pure virtual] |
Test the icon for overlap, with its top left (not its hotspot) at aTopLeft.
Implemented in CartoType::CBoxIcon, and CartoType::CBitmapIcon.
