Hi,
I want create a label fully justified…
On cocos2d ObjectiveC I use NSMutableParagraphStyle with alignement NSTextAlignmentJustified and when I create my label I use CCLabelTTF labelWithAttributedString…
He dont have equivalent on cocos2d-x… someone have already do this or can help ?
Thanks,
Carl
What version of Cocos2d-x are you using?
I use the version 3.15
can you help me ?
I would say you need to make this yourself. It’s not really hard to do. You can easily figure out the number of words and then the math to spread it.
is what I have done… but I asked if someone have already done 
It can be a good add-on on the next release.
Carl;
Could you share your code please? 
Hi, everyone, we are developing on game and we need exactly this thing, but we are still new to all this, so can anyone tell how can we done it, any example or sample @slackmoehrle @sevent7 @NMCarl
tanks in advance 
To full justify a label?
thanks for reply @slackmoehrle i have done all first three part , can you explain me how can do forth one, thanks for reply
kerning is the space between characters. So I think you need to do something like:
okay we will try and let you know, mean while if you got any sample or example anyone have ever done then please let me know
I can try to play with this if I have time, but I’m pretty busy these days. Perhaps start with cocos new and just add a label and start playing around. If you get close, send me the code that I can just drop in to a new project and help too.
@slackmoehrle oh that’s great, well we were trying and find this code from stack overflow
and it’s work with CPP and when we pass the string to this function and print with cocos2d::log() it print with justify, but then when we pass it to label, richtext it just doesn’t work, can you look into it we are so close, hope you will get time…
some screenshot that we did experiment
this is in the terminal with log() function and belove is with the label in cocos2dx
Wow glad the concept at least works.
Can you share your code with me so I can play with it?
@slackmoehrle thanks again for reply, this function we are using , and return paragraph with justify
typedef std::list<std::string> WordList;
const int pageWidth = 40;
std::string mainString;
std::vector<std::string> strings;
std::string Singleton::justifyText( const std::string &text )
{
WordList words = splitTextIntoWords(text);
std::string line;
for (const std::string& word : words) {
if (line.size() + word.size() + 1 > pageWidth) { // next word doesn't fit into the line.
justifyLine(line);
line.clear();
line = word;
} else {
if (!line.empty()) {
line.append(" ");
}
line.append(word);
}
}
mainString = mainString + line;
strings.push_back(line);
cocos2d::log("output here: %s", mainString.c_str());
return mainString;
}
void Singleton::justifyLine( std::string line )
{
size_t pos = line.find_first_of(' ');
if (pos != std::string::npos) {
while (line.size() < pageWidth) {
pos = line.find_first_not_of(' ', pos);
line.insert(pos, " ");
pos = line.find_first_of(' ', pos+1);
if (pos == std::string::npos) {
pos = line.find_first_of(' ');
}
}
}
// std::cout << line << std::endl;
mainString = mainString + line + '\n';
strings.push_back(line);
cocos2d::log("output : %s", line.c_str());
}
WordList Singleton::splitTextIntoWords( const std::string &text )
{
WordList words;
std::istringstream in(text);
std::copy(std::istream_iterator<std::string>(in),
std::istream_iterator<std::string>(),
std::back_inserter(words));
return words;
}
and we are calling this function like this
node->ComplainWidget = Widget::create();
node->ComplainList->pushBackCustomItem(node->ComplainWidget);
auto verString = Singleton::getInstance()->justifyText(Language::getInstance()->getStringForKey1("PokerComplainPara1"));
//Poker Complain Para 1
Label *ComplainPara1 = Label::createWithSystemFont(verString , "Helvetica.ttf", frameSize.height * textSize);
ComplainPara1->setAnchorPoint(Point::ANCHOR_BOTTOM_LEFT);
ComplainPara1->setColor(GrayTextTutorial);
ComplainPara1->setDimensions((ComplainPara1->getContentSize().width) , 0);
ComplainPara1->setLineSpacing(frameSize.height * 0.006f); //Spacing between two lines in para
node->ComplainWidget->addChild(ComplainPara1,3);
node->ComplainWidget->setContentSize(ComplainPara1->getContentSize());
so when we print
cocos2d::log(“output here: %s”, mainString.c_str());
in
std::string Singleton::justifyText( const std::string &text ){…}
it prints perfectly but when we are setting it to label right side not justifying somehow
if you need any help just ping us
Do you have a cpp and header I can drop into a project?
yes wait, I am sending it
PM is fine.
this is the singleton file… and you can call it from thereSingleton.cpp (12.3 KB) Singleton.h (3.2 KB)
you can call
auto verString = Singleton::getInstance()->justifyText(“Poker is a family of card games that combines gambling, strategy and skill.All poker Variant involve betting as an intrinsic part of play and determine the winner of each hand according to the combinations of players’ cards, at least some of which remain hidden untill the end of the hand.Poker games vary in the number of cards dealt,the number of shared or ‘community’ cards, the number of cards that remain hidden,and the betting procedures.”);
Thanks. I will find some time to play with this so we can make a feature request on GitHub issues.
