QComboBox::setModel emits editTextChanged, how to block this?

I am setting a model to QComboBox on editTextChanged. While setting a model it again emits an editTextChanged signal on editTextChanged. I am using an SQL like query for filtering combobox items. pls help me

Solution

  • You can temporarily disable all signals emitted from QComboBox using blockSignals(ture);

    QComboBox* combo = /* ..... */

combo->blockSignals(true);
combo->setModel(newModel);
combo->blockSignals(false);
