I'm trying to get my hands dirty on some Rosegarden code and have been
looking at a minor issue in the TimeWidget. Specifically, the
Millisecond spinbox doesn't handle keyboard input correctly -- if I
type in "451", I get "340" in the text box; if I type "650, I get
"539". None of the other spinbox widgets have this behavior, and I'm
not sure why this one is doing it. The only thing I can think of is
that it's tied to a realtime calculation and it's getting adjusted
inaccurately.
Here's the relevant code in TimeWidget.cpp:
--- init code --
label = new QLabel(tr("msec:"));
label->setAlignment(Qt::AlignRight | Qt::AlignVCenter);
layout->addWidget(label, 2, 2);
if (editable) {
m_msecLabel = 0;
m_msec = new QSpinBox;
m_msec->setMinimum(0);
m_msec->setSingleStep(10);
connect(m_msec, SIGNAL(valueChanged(int)),
this, SLOT(slotSecOrMSecChanged(int)));
layout->addWidget(m_msec, 2, 3);
} else {
m_msec = 0;
m_msecLabel = new LineEdit;
m_msecLabel->setReadOnly(true);
layout->addWidget(m_msecLabel, 2, 3);
}
-- slotSecOrMSecChanged --
void
TimeWidget::slotSecOrMSecChanged(int)
{
int sec = m_sec->value();
int msec = m_msec->value();
slotSetRealTime(RealTime(sec, msec * 1000000));
}
-- populate --
if (m_msec) {
m_msec->setMinimum(0);
m_msec->setMaximum(999);
m_msec->setValue(rt.msec());
} else {
m_msecLabel->setText(QString("%1").arg(rt.msec()));
}
