Textblock Object Functions

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_page

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.
  • font_size - The font size in points.

const char* evas_object_textblock_bidi_delimiters_get ( const Efl_Canvas_Textblock *  obj)

BiDi delimiters are used for in-paragraph separation of bidi segments. This is useful, for example, in the recipient fields of e-mail clients where bidi oddities can occur when mixing RTL and LTR.

Parameters:
[in]objThe object.
Returns:
A null terminated string of delimiters, e.g ",|" or null if empty
Since (EFL) :

)

BiDi delimiters are used for in-paragraph separation of bidi segments. This is useful, for example, in the recipient fields of e-mail clients where bidi oddities can occur when mixing RTL and LTR.

Parameters:
[in]objThe object.
[in]delimA null terminated string of delimiters, e.g ",|" or null if empty
Since (EFL) :
1.18
Since :
2.3.1

Clear the textblock object.

Note:
Does *NOT* free the Evas object itself.
Parameters:
objthe object to clear.
Returns:
nothing.
Since :
2.3.1

Get the object's main cursor.

Since :
2.3.1

Create a new cursor, associate it to the obj and init it to point to the start of the textblock.

Association to the object means the cursor will be updated when the object will change.

Note: if you need speed and you know what you are doing, it's slightly faster to just allocate the cursor yourself and not associate it. (only people developing the actual object, and not users of the object).

Parameters:
objThe textblock to which the new cursor will associate.
Returns:
Returns a new cursor associated with the given textblock object.

Triggers for relayout due to obstacles' state change.

The obstacles alone don't affect the layout, until this is called. Use this after doing changes (moving, positioning etc.) in the obstacles that you would like to be considered in the layout.

For example: if you have just repositioned the obstacles to differrent coordinates relative to the textblock, you need to call this so it will consider this new state and will relayout the text.

Parameters:
[in]objThe object.
Since (EFL) :
1.18

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.

The main difference between this and evas_object_textblock_size_native_get is that the "native" function does not wrapping into account it just calculates the real width of the object if it was placed on an infinite canvas, while this function gives the size after wrapping according to the size restrictions of the object.

For example for a textblock containing the text: "You shall not pass!" with no margins or padding and assuming a monospace font and a size of 7x10 char widths (for simplicity) has a native size of 19x1 and a formatted size of 5x4.

Parameters:
[in]objThe object.
[out]widthThe width of the object.
[out]heightThe height of the object.

won't work here. For those kind of things use markup prepend.

Parameters:
curthe cursor to where to add format at.
formatthe format to add.

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.
