• wk border box (default): background is painted to outside edge of the border
• wk content box: background is painted within the content box
• wk padding box: background is painted to outside edge of the padding (or to inside edge of the border, if any)

• a CSS color ("#010101" or "#FFFFFF" or "red").
• a 4D color longint value (see OBJECT SET RGB COLORS command)

Default for documents is "#FFFFFF" and wk transparent, or "transparent" for paragraphs and images.

Sets the display mode of images used as background, based on a preset of the following "real" attribute values: wk background origin, wk background repeat, wk background position horizontal, wk background position vertical, wk background width, wk background height

Possible values:

• wk proportional
• wk proportional centered

• wk replicated centered

Note: The origin rectangle is set to the padding box (the image rectangle including the padding area but excluding the border area).

When getting the value of this attribute, the returned value is either:

• one of the possible display modes, for example wk replicated, if all the real attributes have the preset values for this mode
• "custom" if at least one real attribute's value differs from the preset ones for any mode. For example, if the preset value of wk background width is changed after applying wk background display mode, WP GET ATTRIBUTES returns "custom" when getting the value of wk background display mode.

Returns last modification date of document (date). This value is read-only and cannot be set.

Note that this value is dynamically updated each time the document contents are edited, but not when the document is opened or saved. 

Indicates if the document has been modified since its associated object was created (see below). Possible values:

• True - document has been modified
• False - document has not been modified (default when the object is created)

This property is always set to false when the object containing the document is created (i.e. with WP Import document, WP New, an object copy or when the object field/attribute is loaded from the database). It is automatically set to true by 4D Write Pro as soon as a modification is done to the contents of the document, whatever the origin of the modification (user action or programming). 

Notes: 

• A new value evaluated from a formula or a new image loaded from a URL is not considered as a document modification (the source string is left untouched). 
• Once set to true by 4D Write Pro, this property is never automatically set back to false, even if an "undo" or an "export" action is executed. However, since it is a read-write property, it can be set by your code.
• Unlike wk date modified, wk modified is volatile, i.e. it is not stored in the document.

• wk point or comma: use the first dot or comma from the right (default for new blank documents)
• wk point: use the point character
• wk comma: use the comma character
• wk system: use decimal separator as returned by GET SYSTEM FORMAT (default for imported legacy 4D Write documents)

• wk true to set selected characters to bold font style; with the WP GET ATTRIBUTES command, wk true is returned if at least one selected character supports a bold font style.
• wk false (default) to remove the bold font style from selected characters if any; with the WP GET ATTRIBUTES command, wk false is returned if none of the selected characters supports a bold font style.

Note: As a shortcut for defining the offset only, you can directly pass a numeric value in the current unit (e.g., 1.5) or a CSS text value (e.g., "3cm"). 4D will construct the tab object automatically.

COMPATIBILITY NOTE: While this selector continues to work for compatibility purposes, it is recommended to use wk tab default or wk tabs instead. 

Specifies the leading characters for tabs in paragraph ranges.
Possible values:

• Text array

Synchronized with the wk tab stop offsets and wk tab stop types arrays.

COMPATIBILITY NOTE: While this selector continues to work for compatibility purposes, it is recommended to use wk tab default or wk tabs instead.

• Array of tab offset values
  COMPATIBILITY NOTE: Previously the last value of the array was the default tab offset value (not an absolute value). As of 4D v17 R5, the last value is an absolute value (not the default value). Use wk tab default to define the default tab value.

Synchronized with the wk tab stop leadings and wk tab stop types arrays.

Note: As a shortcut for defining the offset only, when using WP SET ATTRIBUTES you can pass a numeric value in the current unit (e.g., 1.5) or a CSS text value (e.g., "3cm") as a collection element. 4D will construct the tab object automatically.

• false (default): do not add carry-over rows at the bottom of split tables

This feature is only available with tables filled by datasources returning a non-empty collections or entity selections. In any other context, the bottom carry-over row, if designed, is rendered as a regular row.
