convert char *string to QString

[vinithr]

hi,

I am new to QT. i am not getting the proper way to convert a char * string to QString that i need to display in lineEdit.

Here is the scenario:

I have a header file my_header.h In that i have a variable named char * string. This variable will update by some other application.

I need to update this variable into a lineEdit that accept only QString.. Could you please tell me how i can convert that to QString.

And I need to do reverse operation also.such as i need to get data from line edit and update in the variable in the header..


Thanks in advance

Search for sprintf function in QString.

char *data = "string";
QString str;
str.sprintf("%s",data);
qDebug() << str;

[kito]

you can just

char* data = "string";
QString str;
str = data;

This should work also.

sprintf is useful for other stuff
QString has constructor that takes a char* (and, as kito said, the operator= also can take char*).

You may need to take into consideration encoding of the C-style string also: is it plain ASCII, Latin 1, UTF-8 or some other supported encoding? QString has a range of static conversion functions for handling these differences if the default constructor/operator=() handling is not quite right.
