QComboBox - defines the selected element based on the data of the element
advertisements
What would be the best way of selecting an item in a QT combo box out of a prefined list of enum based unique values.
In the past I have become accustomed to .NET's style of selection where the item can be selected by setting the selected property to the item's value you wish to select:
cboExample.SelectedValue = 2;
Is there anyway to do this with QT based on the item's data, if the data is a C++ enumeration?
You lookup the value of the data with findData and then use setCurrentIndex
QComboBox* combo = new QComboBox;
combo->addItem("100",100.0); // 2nd parameter can be any Qt type
combo->addItem .....
float value=100.0;
int index = combo->findData(value);
if ( index != -1 ) { // -1 for not found
combo->setCurrentIndex(index);
}
