示例1: setValue

{
if(value == new_value)
return;
value = new_value;
if(!GUI)
return;
if(QString(GUI->metaObject()->className()) == "QSlider")
{
QSlider *slider = (QSlider*)GUI;
if(slider->maximum() == 10) // int
slider->setValue(new_value.toInt());
else
slider->setValue(new_value.toFloat()*5.0);
}
if(QString(GUI->metaObject()->className()) == "QColorToolButton")
{
((QColorToolButton*)GUI)->setColor(new_value.toInt());

{
((QDoubleSpinBox*)GUI)->setValue(new_value.toFloat());
}

{
((QSpinBox*)GUI)->setValue(new_value.toInt());
}
if(QString(GUI->metaObject()->className()) == "QComboBox")
{
((QComboBox*)GUI)->setCurrentIndex(new_value.toInt());
}
}示例2: setChOutRange
/**
Sets the minimum/maximum value of the channel 0 to seven output sliders.
Have to do it here because setMinimum is not a slot.
One added trick: if the slider is at either its max or its min when the value
is changed, then keep it on the max/min.
*/
void ConfigServoWidget::setChOutRange()
{
QSpinBox *spinbox = (QSpinBox*)QObject::sender();
int index = outMin.indexOf(spinbox); // This is the channel number
if (index < 0)
index = outMax.indexOf(spinbox); // We can't know if the signal came from min or max
QSlider *slider = outSliders[index];
int oldMini = slider->minimum();
int oldMaxi = slider->maximum();
if (outMin[index]->value()<outMax[index]->value())
{

}
else
{

reversals[index]->setChecked(true);
}
if (slider->value() == oldMini)
slider->setValue(slider->minimum());
// if (slider->value() == oldMaxi)
// slider->setValue(slider->maximum()); // this can be dangerous if it happens to be controlling a motor at the time!
}示例3: setLogoRatio
void SettingsWindow::setLogoRatio(int sliderValue)
{
QSlider *slider = reinterpret_cast<QSlider *>(sender());
qreal steps = slider->maximum() - slider->minimum();
qreal ratio = sliderValue / steps;
_settings->setLogoSizeRatio(ratio);
