How many bytes can enter? (use Event.KEY_CHAR)

luyimoon

local input = editbox.new(TTFont.new("simhei.ttf",40,""),'')

editbox = Core.class(TextField)

function editbox:init(ttf,string)
self:addEventListener(Event.KEY_CHAR,self.key_char,self)
end

function editbox:key_char(e)--over five char(utf8 chinese) can't get it,and how to achieve it (over five char)
local str = self:getText()..e.text
self:setText(str)
stage:addChild(self)
end

I can have over 5 characters this way but I don't have a chinese keyboard to check when typing other letters:

editbox = Core.class(TextField)   function editbox:init(xttf, xstring) self:addEventListener(Event.KEY_CHAR, self.key_char, self) end   function editbox:key_char(e)--over five char(utf8 chinese) can't get it,and how to achieve it (over five char) local str = self:getText()..e.text self:setText(str) stage:addChild(self) end   ----   application:setBackgroundColor(0x555555) local text = "你好世界！, 你好世界！" local input = editbox.new(TTFont.new("fonts/simhei.ttf",40,""), text) input:setPosition(64, 64) stage:addChild(input)

emm...
if use english keyboard ,every time when you input, "e.text" just 1 byte.

and i seen "application:setTextInput()" ,but it can't work in win32.

luyimoon I think you may need the harfbuzz plugin.


It is not documented in the wiki but I believe you just need to add it to your project and the textfields will use it.

and when harfbuzz was added to gideros as a plugin:

For non latin language each letter will be 1 byte and for eastern languages 2 or more bytes.

Key char event was supposed to report only one character at a time, I am surprised you can even get more than one already. On which os/platform is this happening ?

Ok, I understand, your input engine buffers characters and supply a whole sentence to the system, instead of individual characters. Gideros buffer is limited to 16 bytes (here: https://github.com/gideros/gideros/blob/master/libgid/include/ginput.h#L144), because we assumed it was enough to old two or three UTF-8 characters resulting from a composition sequence.
As a quick way to make it work for your case, I can enlarge the buffer, but what would be a reasonable size ? 1024 would allow more than 300 3-byte characters, is that enough ?

i think 1024 is enough.
