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

Question

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

Answer 1

You could disconnect the signal from the slot(s) before setting the new model, and connect it again afterwards.

Answer 2

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

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

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