[solved]Troubles with textEdit signals

  • I'm tryin to use textEdit signal textChanged() to call slot mySlot(QString), which should make button available when user is typing some text.

    void MyDialogWindow::mySlot(QString str)

    connect(ui->textEdit, SIGNAL(textChanged(QString)), this, SLOT(mySlot(QString));

    But when I type some text nothing happens. If I use lineEdit instead textEdit - everything is ok and mySlot works fine. What's the problem with textEdit signal?

    Hi and welcome to devnet,

    QTeditEdit's textChanged is a signal with not parameter, you can't connect it to a slot that has a parameter. Just remove it, and check your textEdit content there.
