|
// History:
|
|
//
|
|
// LEON 04-08-2001
|
|
// Added styleData functionality for extending the style dropdown
|
|
//
|
|
// OZ 30-08-2001
|
|
// Re-worked styleData to restore FormatBlock logic which works better
|
|
// for some styles, for example, heading styles - as these can be
|
|
// applied without having to select text.
|
|
//
|
|
// OZ 02-09-2001
|
|
// Extended the richeditor interface to make the docHtml property read
|
|
// write.
|
|
//
|
|
// OZ 08-01-2002
|
|
// Extended the richeditor interface to include an options property.
|
|
// This property can be set to enable/disable functionality in the
|
|
// editor.
|
|
//
|
|
// OZ 21-01-2002
|
|
// After set editor options, apply them. In some circumstances the
|
|
// options property is set after the editor has initialised and so the
|
|
// options need to be re-applied.
|
|
//
|
|
// OZ 12-02-2002
|
|
// Add new property debugWindow which should be a reference to an HTML
|
|
// element that can contain innerHTML. A table is inserted into this
|
|
// element and debug statements are output.
|
|
//
|
|
// OZ 12-06-2002 [ richtext-Bugs-567677 ] Cursor at bottom of document on load
|
|
// When initialising HTML throught the docHtml property, get a text range
|
|
// object before inserting HTML (this will reflect the cursor position for
|
|
// the empty document), insert the HTML (this moves the cursor position)
|
|
// and then collapse the resulting range which now covers the entire document
|
|
// to the beginning (i.e. move the insertion point to the start of the
|
|
// selection). All changes isolated to the put_docHtml() routine.
|
|
//
|
|
// OZ 18-06-2002
|
|
// Add support for a docXHtml property to allow an XHMTL representation
|
|
// of the document to be extracted. See rte_xhtml.js for the
|
|
// implementation.
|
|
//
|
|
// OZ 01-07-2002
|
|
// If the editor is slow at initialisation (for example if an alert box
|
|
// is placed inside initEditor() in rte.js) then it is possible for
|
|
// the docHtml property to be called before the editor is properly
|
|
// initialised. This is ok except that we can't put focus on the editor
|
|
// until it is visible.
