QLineEdit and cursor position
Message 1 in thread
Hello,
I want select text in a QLineEdit and move the cursor to the first
characher without unselect the text.
The easy solution using QLineEdit::selectAll and
QLineEdit::setCursorPosition doesn't work, because setCursorPosition
unselect the text and selectAll moves the cursor to the end.
Is there a solution to this problem?
Thanks.
#include <qapplication.h>
#include <qapplication.h>
#include <qlineedit.h>
#include <qstring.h>
int main(int argc, char** argv){
QApplication qapp(argc, argv);
QString* msg = new QString("Do not feed the trolls!!!!!!!!!!!!!!!!!!!!!!");
QLineEdit* ql = new QLineEdit(NULL);
ql->setText(*msg);
ql->selectAll();
ql->setCursorPosition(0);
qapp.setMainWidget(ql);
ql->show();
return qapp.exec();
}

Hello,
If your are using Qt 4.X, you might use :
QLineEdit::setSelection( 6, -4);
for example, to select backward four characters starting at the sixth.
Cheers

Unfortunately, I'm using Qt 3.3 and I could not move to Qt 4 easily.
Is there no possibility with Qt 3.x?

In that case, and it's a wild guess, did you try "void
QLineEdit::cursorBackward ( bool mark, int steps = 1 )" ?
Looking in the doc, it might be just what you need with mark = TRUE.
