How to get focus of QLineEdit in Qt4.5

Question

When i click Qlineedit i want the focus and at the same time i want to edit for multiple linedits for using virtual keyboard.

Answer 1

Subclass QLineEdit and implement QWidget::focusInEvent(QFocusEvent *); and set a global variable to the current linedit and use that from your virtual keyboard.

ex (not real code) :

void myLineEdit::focusInEvent ( QFocusEvent * ) {
     myapp->currentLineEdit = this;
 }
 //virtual keyboard 
 if(myapp->currentLineEdit) abuse(myapp->currentLineEdit);
