Detailed Description

Functions used to create and manipulate textblock objects.

Unlike Text Object Functions, these handle complex text, doing multiple styles and multiline text based on HTML-like tags. Of these extra features will be heavier on memory and processing cost.

Textblock Object Tutorial

This part explains about the textblock object's API and proper usage. The main user of the textblock object is the edje entry object in Edje, so that's a good place to learn from, but I think this document is more than enough, if it's not, please contact me and I'll update it.

Introduction

The textblock objects is, as implied, an object that can show big chunks of text. Textblock supports many features including: Text formatting, automatic and manual text alignment, embedding items (for example icons) and more. Textblock has three important parts, the text paragraphs, the format nodes and the cursors.

You can use markup to format text, for example: "<font_size=50>Big!</font_size>". You can also put more than one style directive in one tag: "<font_size=50 color=#F00>Big and Red!</font_size>". Please notice that we used "</font_size>" although the format also included color, this is because the first format determines the matching closing tag's name. You can also use anonymous tags, like: "<font_size=30>Big</>" which just pop any type of format, but it's advised to use the named alternatives instead.

Textblock Object Cursors

A textblock Cursor is data type that represents a position in a textblock. Each cursor contains information about the paragraph it points to, the position in that paragraph and the object itself. Cursors register to textblock objects upon creation, this means that once you created a cursor, it belongs to a specific obj and you can't for example copy a cursor "into" a cursor of a different object. Registered cursors also have the added benefit of updating automatically upon textblock changes, this means that if you have a cursor pointing to a specific character, it'll still point to it even after you change the whole object completely (as long as the char was not deleted), this is not possible without updating, because as mentioned, each cursor holds a character position. There are many functions that handle cursors, just check out the evas_textblock_cursor* functions. For creation and deletion of cursors check out:

See also: evas_object_textblock_cursor_new(); evas_textblock_cursor_free()

Note: Cursors are generally the correct way to handle text in the textblock object, and there are enough functions to do everything you need with them (no need to get big chunks of text and processing them yourself).

Textblock Object Paragraphs

The textblock object is made out of text splitted to paragraphs (delimited by the paragraph separation character). Each paragraph has many (or none) format nodes associated with it which are responsible for the formatting of that paragraph.

Textblock Object Format Nodes

As explained in Textblock Object Paragraphs each one of the format nodes is associated with a paragraph. There are two types of format nodes, visible and invisible: Visible: formats that a cursor can point to, i.e formats that occupy space, for example: newlines, tabs, items and etc. Some visible items are made of two parts, in this case, only the opening tag is visible. A closing tag (i.e a </tag> tag) should NEVER be visible. Invisible: formats that don't occupy space, for example: bold and underline. Being able to access format nodes is very important for some uses. For example, edje uses the "<a>" format to create links in the text (and pop popups above them when clicked). For the textblock object a is just a formatting instruction (how to color the text), but edje utilizes the access to the format nodes to make it do more. For more information, take a look at all the evas_textblock_node_format_* functions. The translation of "<tag>" tags to actual format is done according to the tags defined in the style, see evas_textblock_style_set

Special Formats

Textblock supports various format directives that can be used in markup. In addition to the mentioned format directives, textblock allows creating additional format directives using "tags" that can be set in the style see evas_textblock_style_set .

For more details see Evas Textblock Style Options

Textblock supports the following formats:

font - Font description in fontconfig like format, e.g: "Sans:style=Italic:lang=hi". or "Serif:style=Bold".
font_weight - Overrides the weight defined in "font". E.g: "font_weight=Bold" is the same as "font=:style=Bold". Supported weights: "normal", "thin", "ultralight", "light", "book", "medium", "semibold", "bold", "ultrabold", "black", and "extrablack".
font_style - Overrides the style defined in "font". E.g: "font_style=Italic" is the same as "font=:style=Italic". Supported styles: "normal", "oblique", and "italic".
font_width - Overrides the width defined in "font". E.g: "font_width=Condensed" is the same as "font=:style=Condensed". Supported widths: "normal", "ultracondensed", "extracondensed", "condensed", "semicondensed", "semiexpanded", "expanded", "extraexpanded", and "ultraexpanded".
lang - Overrides the language defined in "font". E.g: "lang=he" is the same as "font=:lang=he".
font_fallbacks - A comma delimited list of fonts to try if finding the main font fails.

EVAS_API void evas_object_textblock_size_formatted_get	(	const Efl_Canvas_Textblock *	obj,
		int *	width,
		int *	height
	)

The formatted width and height.

This calculates the actual size after restricting the textblock to the current size of the object.

Returns the geometry of two cursors ("split cursor"), if logical cursor is between LTR/RTL text, also considering paragraph direction.

Upper cursor is shown for the text of the same direction as paragraph, lower cursor - for opposite.

Split cursor geometry is valid only in '|' cursor mode. In this case EINA_TRUE is returned and cx2, cy2, cw2, ch2 are set, otherwise it behaves like cursor_geometry_get.

Parameters

		Evas_Coord *	cw,
		Evas_Coord *	ch,
		Evas_BiDi_Direction *	dir,
		Evas_Textblock_Cursor_Type	ctype
	)

Returns the geometry of the cursor.

Depends on the type of cursor requested. This should be used instead of char_geometry_get because there are weird special cases with BiDi text. in '_' cursor mode (i.e a line below the char) it's the same as char_geometry get, except for the case of the last char of a line which depends on the paragraph direction.

in '|' cursor mode (i.e a line between two chars) it is very variable. For example consider the following visual string: "abcCBA" (ABC are rtl chars), a cursor pointing on A should actually draw a '|' between the c and the C.

Parameters

cur	the cursor.
cx	the x of the cursor
cy	the y of the cursor
cw	the width of the cursor
ch	the height of the cursor
dir	the direction of the cursor, can be NULL.
ctype	the type of the cursor.
