graphical <- active: bool

Indicate whether or not typing will affect this caret. The visual feedback depends on the text_cursor<-style.

text_cursor <- hot_spot: point*

When text_cursor<->style is image; this point describes how the image object is positioned relative to the character.

text_cursor <- image: image*

When text_cursor<->style is image; this is the image object.

text_cursor <- style: {bar,block,underline,xpce,image}

Style of the text_cursor. Values are:

bar

A thin vertical bar before the character at the caret.

block

A translucent box over the character at the caret. If the caret is not text_cursor->active, the box is drawn as an outline.

underline

A line below the character at the caret.

xpce

The classic xpce caret: a small triangle below the insertion point if the cursor is text_cursor->active, a diamond otherwise.

image

An arbitrary image, set using text_cursor->image.

An inactive caret uses text_cursor.inactive_colour. The style is set by text_cursor->font from text_cursor.fixed_font_style or text_cursor.proportional_font_style.
