Description
The QDateTimeEdit widget does not honour selectedSection() when shown.
The example code should display the date time with the day section highlighted when the widget is shown. It shows the correct date time but the first section (year in this case) is the one that is highlighted. The return value from currentSection() == DaySection, and the correct text is returned if used in sectionText(). If the user starts typing the year section is the one that is edited.
I have also tried deferring the setSelectedSection() call until after the show() with a zero timer. On Linux this results in no section being highlighted in the editor (no focus) although the DaySection is the current section. If you edit2->setFocus() its year section is highlighted.
This may be related to long-closed bug QTBUG-11046
#include <QApplication> #include <QDateTimeEdit> #include <QVBoxLayout> #include <QTimer> #include <QDebug> class Widget: public QWidget { Q_OBJECT QDateTimeEdit *edit1; QDateTimeEdit *edit2; public: Widget(QWidget *p = 0): QWidget(p) { edit1 = new QDateTimeEdit(this); edit1->setDateTime(QDateTime(QDate(2013,11,12), QTime(13, 14, 0))); edit1->setDisplayFormat("yyyy-MM-dd hh:mm"); edit1->setSelectedSection(QDateTimeEdit::DaySection); edit2 = new QDateTimeEdit(this); edit2->setDateTime(QDateTime(QDate(2013,11,12), QTime(13, 14, 0))); edit2->setDisplayFormat("yyyy-MM-dd hh:mm"); QVBoxLayout *layout = new QVBoxLayout; layout->addWidget(edit1); layout->addWidget(edit2); setLayout(layout); QTimer::singleShot(0, this, SLOT(delayed())); } private slots: void delayed() { edit2->setSelectedSection(QDateTimeEdit::DaySection); qDebug() << edit1->currentSection() << edit1->sectionText(edit1->currentSection()); qDebug() << edit2->currentSection() << edit2->sectionText(edit2->currentSection()); } }; int main(int argc, char **argv) { QApplication app(argc, argv); Widget w; w.show(); return app.exec(); } #include "main.moc"
It appears that the focusInEvent() is resetting the currentSection() so I am working around this by subclassing QDateTimeEdit:
class Edit: public QDateTimeEdit { public: Edit(QWidget *p): QDateTimeEdit(p) { } protected: void focusInEvent(QFocusEvent *event) { Section section = currentSection(); QDateTimeEdit::focusInEvent(event); setSelectedSection(section); } };
