Detailed Description

Holds a little bit of text.

This is for very simple text labels and such. There can be multiple lines of text with variable centering. One CaptionData unit should be considered one "point" when the object is scaled same as paper.

Member Function Documentation

int LaxInterfaces::CaptionData::ComputeLineLen ( int line )

virtual

Update cached pixel length of line. Also return that value.

If line<0 then compute for all lines, and returns maximum length.

void LaxInterfaces::CaptionData::dump_out	(	FILE *	f,
		int	indent,
		int	what,
		Laxkit::anObject *	context
	)

virtual

Default dump for a CaptionData.

Dumps:

  font aontuhaot.ttf
  fontsize 10
  xcentering  50
  ycentering  50
  text \
    Blah Blah.
    Blah, "blah blah"

width and height are the integer pixel dimensions of the image.

Ignores what. Uses 0 for it.

Reimplemented from LaxInterfaces::SomeData.

void LaxInterfaces::CaptionData::FindBBox ( )

virtual

Assumes font is accurate????

Todo:: *** must be able to find the actual extent of the text! right now, the interface must handle bbox finding.

Reimplemented from LaxInterfaces::SomeData.

Referenced by LaxInterfaces::CaptionInterface::Refresh().

int LaxInterfaces::CaptionData::SetText ( const char * newtext )

virtual

Set new text.

Accepts multi line text, where lines are delineated with '
'.

Returns 0 for success, 1 for error.

References split().

Referenced by LaxInterfaces::CaptionInterface::newData().

Member Data Documentation

double LaxInterfaces::CaptionData::fontsize

The point size of the font.

This size is relative to the object's coordinate space which are assumed to be inches. Thus a fontsize of 1pt will be 1/72nd of 1 unit in the object's space.

Referenced by LaxInterfaces::CaptionInterface::Refresh().

double LaxInterfaces::CaptionData::xcentering

0 is left, 100 is right, 50 is center, and other number is partial centering.

All centering is around the origin.

Referenced by LaxInterfaces::CaptionInterface::Refresh().

double LaxInterfaces::CaptionData::ycentering

0 is top, 100 is bottom, 50 is center, and other number is partial centering.

All centering is around the origin.
