QMultiHash - crashing

[steg90]

Hi,

strId is set to "1911" for testing purposes, but sometimes it is a bad ptr and I don't know why?

Possible because this function gets called from another thread, well I say that, the other thread emits a signal which causes this code to be called, the other thread does pass across a pointer to the following data structure :

struct MESSAGEDATA
{
	QString strId;
	QString strData;
};

struct MESSAGEDATA
{
	QString strId;
	QString strData;
};

To copy to clipboard, switch view to plain text mode 

Thread just does :

MESSAGEDATA can[MAX];
 
		can[0].strId = "1911";
		can[0].strData = "0F0F0F0F0F0F";
		emit modifytable( &can[0] );

MESSAGEDATA can[MAX];

		can[0].strId = "1911";
		can[0].strData = "0F0F0F0F0F0F";
		emit modifytable( &can[0] );

To copy to clipboard, switch view to plain text mode 

Quite possible I've answered my own question, it could be the fact that passing a pointer to this structure is not safe?

And the modifytable slot function is :

void CanTree::updatetable( MESSAGEDATA* pData )
{
	m_pModel->updateTable( pData->strData, pData->strId );
}

void CanTree::updatetable( MESSAGEDATA* pData )
{
	m_pModel->updateTable( pData->strData, pData->strId );
}

To copy to clipboard, switch view to plain text mode 

Which updates the model with the relevant data.

Steve
