class TextProjector2d from StdSelect inherits Projector from Select2D
---Purpose: A projector framework specific to texts in 2D views.
-- For a string of text, an insertion point and a font, it
-- calculates the minimum and maximum points of the text box in the view.
uses
View from V2d,
Trsf2d from gp,
Pnt2d from gp,
ExtendedString from TCollection
is
Create(aView: View from V2d) returns mutable TextProjector2d;
---Purpose: Constructs a 2D text projector framework defined by the 2D view aView.
Set(me:mutable; aView:View from V2d) is static;
---Purpose: Sets the view aView.
---C++: inline
Set(me:mutable;atrsf:Trsf2d from gp)is static;
---Purpose: Sets the transformation atrsf.
-- This transformation is applied to the attachment point
-- of the text, and takes the size and length of the text
-- into account to give the upper right hand point of the text box.
---C++: inline
Convert(me;aPointIn : Pnt2d from gp;
aPointOut : out Pnt2d from gp) is redefined virtual;
---Level: Public
---Purpose: applies the stored trsf to aPointIn to get aPointOut
Convert(me;aText: ExtendedString from TCollection;
XPos,YPos: Real;
MinPoint,MaxPoint: out Pnt2d from gp;
afont : Integer=-1) is virtual;
---Level: Public
---Purpose:XPos,YPos is the AttachPoint for the text.First, the stored Trsf is
-- applied to this point, then we get the size and length of text to
-- give the upper point
fields
myview : View from V2d; --to be replaced by a pointer...
