How do you convert QString to double in Qt? lineEdit->setText("123456789"); QVariant val = lineEdit->text(). toDouble();
The QString class provides an abstraction of Unicode text and the classic C '\0'-terminated char array. More... All the functions in this class are reentrant when Qt is built with thread support.
One way to initialize a QString is simply to pass a const char * to its constructor. For example, the following code creates a QString of size 5 containing the data "Hello": QString str = "Hello"; QString converts the const char * data into Unicode using the fromAscii() function.
You have QString::chop() for the case when you already know how many characters to remove.
It is same as QString::remove(), just works from the back of string.
