Detailed Description

A Widget for rendering text blocks, i.e.

paragraphs or sequences of paragraphs.

Info: Some (not so) recent changes, line breaking and hyphenation, have not yet been incorporated into this documentation. See Changes in Line-Breaking and Hyphenation.

Signals

dw::Textblock uses the signals defined in dw::core::Layout::LinkReceiver, related to links. The coordinates are always -1.

Collapsing Spaces

Info: Collapsing spaces are deprecated, in favor of collapsing margins (see below).

The idea behind this is that every paragraph has a specific vertical space around and that they are combined to one space, according to rules stated below. A paragraph consists either of the lines between two paragraph breaks within a dw::Textblock, or of a dw::Textblock within a dw::Textblock, in a single line; the latter is used for indented boxes and list items.

The rules:

If a paragraph is following by another, the space between them is the maximum of both box spaces:

are combined like this:
a) If one paragraph is the first paragraph within another, the upper space of these paragraphs collapse. b) The analogue is the case for the last box:

If B and C are put into A, the result is:

For achieving this, there are some features of dw::Textblock:

Consequent breaks are automatically combined, according to rule 1. See the code of dw::Textblock::addParBreak for details.
If a break is added as the first word of the dw::Textblock within another dw::Textblock, collapsing according to rule 2a is done automatically. See the code of dw::Textblock::addParBreak.
To collapse spaces according to rule 2b, dw::Textblock::addParBreak::handOverBreak must be called for the inner widget. The HTML parser does this in Html_eventually_pop_dw.

Collapsing Margins

Collapsing margins, as defined in the CSS2 specification, are, supported in addition to collapsing spaces. Also, spaces and margins collapse themselves. I. e., the space between two paragraphs is the maximum of the space calculated as described in "Collapsing Spaces" and the space calculated according to the rules for collapsing margins.

(This is an intermediate hybrid state, collapsing spaces are used in the current version of dillo, while I implemented collapsing margins for the CSS prototype and integrated it already into the main trunk. For a pure CSS-based dillo, collapsing spaces will not be needed anymore, and may be removed for simplicity.)

Currently implemented cases:

The top margin of of the textblock widget and the top margin of the first line box (based on widgets in the first line) collapse.
The bottom margin of of the textblock widget and the bottom margin of the last line box collapse.
The bottom margin of a line box and the top margin of the following line collapse. Here, the break space is regarded, too.

Open issues:

Only the value of Style::margin is regarded, not the result of the collapsing itself. For the widgets A, B (child of A), and C (child of B), the effective margin of A is the maximum of the style margins of A and B, while the effective margin of B (the collapsed margin of B and C) is ignored here. This could be solved by introducing an additional "effective" ("calculated", "collapsed") margin as an attribute of Widget.
For similar reasons, backgrounds to not work exactly. Usage of Widget::extraSpace should fix this, but it is only fully working in the GROWS branch (http://flpsed.org/hgweb/dillo_grows).

Update: This needs to be re-evaluated.
Do margins of inline blocks and tables collapse? Check CSS spec. (They do currently; if not, ignoring them is simple.)
Lines which only contain a BREAK should be skipped for collapsing margins, or at least all three should collapse: the previous margin, the break, and the following margin. (Compare this with the CSS spec.)
Related to this: adding breaks should be revised. Textblock::addLinebreak and Textblock::addParbreak work quite differently, and Textblock::addParbreak seems much to complex for our needs, even when spaces of lines are kept.

Some Internals

There are 4 lists, dw::Textblock::words, dw::Textblock::paragraphs, dw::Textblock::lines, and dw::Textblock::anchors. The word list is quite static; only new words may be added. A word is either text, a widget, or a break.

Lines refer to the word list (first and last). They are completely redundant, i.e., they can be rebuilt from the words. Lines can be rewrapped either completely or partially (see "Incremental Resizing" below). For the latter purpose, several values are accumulated in the lines. See dw::Textblock::Line for details.

A recent change was the introduction of the paragraphs list, which works quite similar, is also redundant, but is used to calculate the extremes, not the size.

Anchors associate the anchor name with the index of the next word at the point of the anchor.

Incremental Resizing

dw::Textblock makes use of incremental resizing as described in Sizes of Dillo Widgets. The parentRef is, for children of a dw::Textblock, simply the number of the line. [Update: Incorrect; see Handling Elements Out Of Flow.]

Generally, there are three cases which may change the size of the widget:

The line break size of the widget has changed, e.g., because the user has changed the size of the browser window. In this case, it is necessary to rewrap all the lines.
A child widget has changed its size. In this case, only a rewrap down from the line where this widget is located is necessary.

(This case is very important for tables. Tables are quite at the bottom, so that a partial rewrap is relevant. Otherwise, tables change their size quite often, so that this is necessary for a fast, non-blocking rendering)
A word (or widget, break etc.) is added to the text block. This makes it possible to reuse the old size by simply adjusting the current width and height, so no rewrapping is necessary.

The state of the size calculation is stored in wrapRef within dw::Textblock, which has the value -1 if no rewrapping of lines necessary, or otherwise the line from which a rewrap is necessary.

Member Enumeration Documentation

◆ anonymous enum

anonymous enum

This class encapsulates the badness/penalty calculation, and so (i) makes changes (hopefully) simpler, and (ii) hides the integer arithmetic (floating point arithmetic avoided for performance reasons).

Unfortunately, the value range of the badness is not well defined, so fiddling with the penalties is a bit difficult.
