[SOLVED] Have text in QLineEdit selected on edit start

yanbellavance

I need to have a QLineEdit's text be selected when it receives focus. Right now it is being done only when I tab into it, not when i click into it. i tried the selectAll() function but that did not work. I tested the selectAll() function in another scenario to verify its functionality and it does work so something is overiding me when and voiding my call to selectAll(). I suspect it is related to the fact that I am clicking but I have strongFocus setup. How can do this? I was calling the selectAll() function inside the focusInEvent:

@void wvQlineEdit::focusInEvent ( QFocusEvent * event ) {

this->setWriteEnable(false);
oldVal=text();
originalVal=text();
selectAll();
QLineEdit::focusInEvent(event);

}@

As wild guess: have you tried to call QLineEdit::focusInEvent(event); before selectAll(); ?

The text is selected in the focusInEvent, but immediately gets deselected by the following mousePressEvent hat is delivered to the line edit.

This code works for me:

@

class wvQlineEdit : public QLineEdit
{
Q_OBJECT
public:
wvQlineEdit(QWidget *parent);
virtual ~wvQlineEdit() {}

protected:
void focusInEvent(QFocusEvent *e);
void mousePressEvent(QMouseEvent *me);

bool _selectOnMousePress;

};

wvQlineEdit::wvQlineEdit(QWidget *parent)
: QLineEdit(parent)
{
_selectOnMousePress = false;
}

void wvQlineEdit::focusInEvent(QFocusEvent *e)
{
QLineEdit::focusInEvent(e);
selectAll();
_selectOnMousePress = true;
}

void wvQlineEdit::mousePressEvent(QMouseEvent *me)
{
QLineEdit::mousePressEvent(me);
if(_selectOnMousePress) {
selectAll();
_selectOnMousePress = false;
}
qDebug() << selectedText();

}
