C++ (Cpp) QPushButton::deleteLater Examples

Example #1

File: ByWeekdayColumnWidget.cpp Project: Rusto/qalendar

// React to a click on a day button, by removing it from the list
void ByWeekdayColumnWidget::onDayClicked()
{
    QPushButton *dayButton = qobject_cast<QPushButton*>(this->sender());

    // Remove the last number button
    listLayout->removeWidget(dayButton);
    dayButton->hide();
    dayButton->deleteLater();

    // Remove the day from the internal list
    days.removeOne(reverse ? -dayButton->text().toInt() : dayButton->text().toInt());
}
