Application crashing on setting Model in QComboBox.

[kaushal_gaurav]

Hi,

My app is crashing when i set the QSortFilterProxyModel in the combo box.
below is the code snippet that i use to set the model to the comboBox

m_TxPowerProxyModel->setDynamicSortFilter(true);
   m_TxPowerProxyModel->setSourceModel(m_Model);
   m_Ui.txPowerCombo->setModel(m_TxPowerProxyModel);
   m_Ui.txPowerCombo->setModelColumn(DevicesModel::TX_POWER);
   m_TxPowerProxyModel->SetModelSearchStr(m_BandProxyModel->data(index).toString());

m_TxPowerProxyModel->setDynamicSortFilter(true);
   m_TxPowerProxyModel->setSourceModel(m_Model);
   m_Ui.txPowerCombo->setModel(m_TxPowerProxyModel);
   m_Ui.txPowerCombo->setModelColumn(DevicesModel::TX_POWER);
   m_TxPowerProxyModel->SetModelSearchStr(m_BandProxyModel->data(index).toString());

did u see which line exactly it is crashing?

[kaushal_gaurav]

The crash is not in these lines.. but is due to these lines.... when i comment these lines the app is fine..
The app is crashing in m_Model's setData() funciton.

So maybe it's crashing because setData() is written wrong? Can we see it?

[kaushal_gaurav]

The app is crashing because of

m_Ui.txPowerCombo->clear();

m_Ui.txPowerCombo->clear();

To copy to clipboard, switch view to plain text mode 

If i comment the line the app works fine.
I need to clear the contents of the combo box because it is coming out to be junk in index 0.
and rest of the combo is populated with the values from the model.

Help...

try to trace clear method, maybe somewhere invalid pointer is used.
