* @internal
|
|
|
|
* @section Evas_Object_Textblock_Internal Internal Textblock Object Tutorial
|
|
|
|
*
|
|
|
|
* This explains the internal design of the Evas Textblock Object.
|
|
|
|
*
|
|
|
|
* @subsection textblock_intro Introduction
|
|
|
|
* There are two main parts to the textblock object, the first being the node
|
|
|
|
* system, and the second being the layout system. The former is just an
|
|
|
|
* internal representation of the markup text, while the latter is the internal
|
|
|
|
* visual representation of the text (i.e positioning, sizing, fonts and etc).
|
|
|
|
*
|
|
|
|
* @subsection textblock_nodes The Nodes system
|
|
|
|
* The nodes mechanism consists of two main data types:
|
|
|
|
* ::Evas_Object_Textblock_Node_Text and ::Evas_Object_Textblock_Node_Format
|
|
|
|
* the former is for Text nodes and the latter is for format nodes.
|
|
|
|
* There's always at least one text node, even if there are only formats.
|
|
|
|
*
|
|
|
|
* @subsection textblock_nodes_text Text nodes
|
|
|
|
* Each text node is essentially a paragraph, it includes an @ref Eina_UStrbuf
|
|
|
|
* that stores the actual paragraph text, a utf8 string to store the paragraph
|
|
|
|
* text in utf8 (which is not used internally at all), A pointer to it's
|
|
|
|
* main @ref textblock_nodes_format "Format Node" and the paragraph's
|
|
|
|
* @ref evas_bidi_props "BiDi properties". The pointer to the format node may be
|
|
|
|
* NULL if there's no format node anywhere before the end of the text node,
|
|
|
|
* not even in previous text nodes. If not NULL, it points to the first format
|
|
|
|
* node pointing to text inside of the text node, or if there is none, it points
|
|
|
|
* to the previous's text nodes format node. Each paragraph has a format node
|
|
|
|
* representing a paragraph separator pointing to it's last position except
|
|
|
|
* for the last paragraph, which has no such constraint. This constraint
|
|
|
|
* happens because text nodes are paragraphs and paragraphs are delimited by
|
|
|
|
* paragraph separators.
|
|
|
|
*
|
|
|
|
* @subsection textblock_nodes_format Format Nodes
|
|
|
|
* Each format node stores a group of format information, for example the
|
|
|
|
* markup: \<font=Vera,Kochi font_size=10 align=left\> will all be inserted
|
|
|
|
* inside the same format node, altohugh it consists of different formatting
|
|
|
|
* commands.
|
|
|
|
* Each node has a pointer to it's text node, this pointer is NEVER NULL, even
|
|
|
|
* if there's only one format, and no text, a text node is created. Each format
|
|
|
|
* node includes an offset from the last format node of the same text node. For
|
|
|
|
* example, the markup "0<b>12</b>" will create two format nodes, the first
|
|
|
|
* having an offset of 1 and the second an offset of 2. Each format node also
|
|
|
|
* includes a @ref Eina_Strbuf that includes the textual representation of the
|
|
|
|
* format, and a boolean stating if the format is a visible format or not, see
|
|
|
|
* @ref textblock_nodes_format_visible
|
|
|
|
*
|
|
|
|
* @subsection textblock_nodes_format_visible Visible Format Nodes
|
|
|
|
* There are two types of format nodes, visible and invisible. They are the same
|
|
|
|
* in every way, except for the representation in the text node. While invisible
|
|
|
|
* format nodes have no representation in the text node, the visible ones do.
|
|
|
|
* The Uniceode replacement character (0xFFFD) is inserted to every place a
|
|
|
|
* visible format node points to. This makes it very easy to treat visible
|
|
|
|
* formats as items in the text, both for BiDi purposes and cursor handling
|
|
|
|
* purposes.
|
|
|
|
* Here are a few example visible an invisible formats:
|
|
|
|
* Visible: newline char, tab, paragraph separator and an embedded item.
|
|
|
|
* Invisible: setting the color, font or alignment of the text.
|
|
|
|
*
|
|
|
|
* @subsection textblock_layout The layout system
|
|
|
|
* @todo write @ref textblock_layout

/* the actual api call to add a textblock */
|
the textblock actually works.
so far the following works:
o = evas_object_textblock_add(evas);
evas_object_move(o, 10, 40);
evas_object_resize(o, win_w - 20, win_h - 50);
evas_object_textblock_format_insert(o, "color=#000000ff");
evas_object_textblock_format_insert(o, "font=/usr/local/share/expedite/data/Vera.ttf size=10");
evas_object_textblock_text_insert(o, "This is 1 line. ");
evas_object_textblock_text_insert(o, "And some more text. ");
evas_object_textblock_format_insert(o, "size=20");
evas_object_textblock_format_insert(o, "color=#f80");
evas_object_textblock_text_insert(o, "Bigger orange text.");
evas_object_textblock_format_insert(o, "size=8");
evas_object_textblock_format_insert(o, "color=#0000ff88");
evas_object_textblock_format_insert(o, "\n");
evas_object_textblock_text_insert(o, "A second line of transparent blue.");
evas_object_show(o);
i need to implement alignment handling next...

the textblock actually works.
so far the following works:
o = evas_object_textblock_add(evas);
evas_object_move(o, 10, 40);
evas_object_resize(o, win_w - 20, win_h - 50);
evas_object_textblock_format_insert(o, "color=#000000ff");
evas_object_textblock_format_insert(o, "font=/usr/local/share/expedite/data/Vera.ttf size=10");
evas_object_textblock_text_insert(o, "This is 1 line. ");
evas_object_textblock_text_insert(o, "And some more text. ");
evas_object_textblock_format_insert(o, "size=20");
evas_object_textblock_format_insert(o, "color=#f80");
evas_object_textblock_text_insert(o, "Bigger orange text.");
evas_object_textblock_format_insert(o, "size=8");
evas_object_textblock_format_insert(o, "color=#0000ff88");
evas_object_textblock_format_insert(o, "\n");
evas_object_textblock_text_insert(o, "A second line of transparent blue.");
evas_object_show(o);
i need to implement alignment handling next...
