Re: [osg-users] osgText::Text, a question about line breaker n
Problem solved! Because I read texts from XML files, so I just put ' ' instead of '\n'. Thanks for all the replies above! -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=56126#56126 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] osgText::Text, a question about line breaker n
Here is what I get:
Set the text using a std::string, which is converted to an internal TextString.
I think I should find out the secret of TextString.

Re: [osg-users] osgText::Text, a question about line breaker n
Forgive my silly typo, I did mean std::string.
It is strange that now
std::string str = "This is the first line \n This is
the second line";
text->setText(str);
works!!!
I don't know why it failed two hours ago.
But if I change the str content with things read from external files, the \n
does not work again'(
When creating the external text files, I already added the breaker into the
contents.
Thanks anyway!!!

Re: [osg-users] osgText::Text, a question about line breaker n
Hi,
Hmm, still have doubts. Because of uppercase String name yu just wrote.
std::String does not exist. I would be ok, though, if you wrote you did
declare it as std::string (lowercase) ;-). But lets assume you did just
that and it still does not work, so then I would suggest to enter setText
call with debugger and see what version of it is called. Is it setText(
const osgText::String & ) or setText( const std::string & ) or
setText(const wchar_t* text) ? See which one is this and then select proper
type as your type for declaring str variable.

Re: [osg-users] osgText::Text, a question about line breaker n
Thanks for your reply.
In my codes, I did declare it as std::String str.
Just simply put String here to illustrate:)

Re: [osg-users] osgText::Text, a question about line breaker n
Hi,
Its just a guess, but I believe your call:
text->setText("This is the first line \n This is the second line");
is done implicit conversion to std::string and calling following method:
TextBase::setText( const std::string & );
so in your code I would try declaring str variable as std::string (not a
String as you did).

Re: [osg-users] osgText::Text, a question about line breaker \n
Hi Fan,
Could you try:
String str = "This is the first line \\n This is the second line";
text->setText(str);
(note the double \)
cheers
Sebastian
Hi all,
Sorry to disturb but I have a question about the line breaker '\n'.
If I use text->setText("This is the first line \n This is the second line");
It works and gets the result as:
This is the first line
This is the second line
But if I read the string from a variable, it does not work, namely,
String str = "This is the first line \n This is the second line";
text->setText(str);
The result will be:
This is the first line \n This is the second line
Anyone knows why and how to deal with it?
I have to read lots of texts from external files.
So it is impossible to do it in the first way to directly put the texts there,
but to read texts each time.
Thanks in advance for any kind reply!
Cheers,
Fan

[osg-users] osgText::Text, a question about line breaker \n
Hi all,
Sorry to disturb but I have a question about the line breaker '\n'.
If I use text->setText("This is the first line \n This is the second line");
It works and gets the result as:
This is the first line
This is the second line
But if I read the string from a variable, it does not work, namely,
String str = "This is the first line \n This is the second line";
text->setText(str);
The result will be:
This is the first line \n This is the second line
Anyone knows why and how to deal with it?
I have to read lots of texts from external files.
So it is impossible to do it in the first way to directly put the texts there,
but to read texts each time.
Thanks in advance for any kind reply!
Cheers,
Fan
