Crash on PropertyGrid delete

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello everyone!

I created a PropertyGrid derived class with empty destructor.
When I delete an instance of this class, 
CXTPPropertyGrid::~CXTPPropertyGrid()

is called: first instruction in this method is 
delete m_pPaintManager; which executes 
CMDTARGET_RELEASE(m_pMetrics);
. This instruction substantially destroys m_pMetrics and resets it to NULL.

CXTPPropertyGrid::~CXTPPropertyGrid() then goes on with:
if (m_pView) {
  delete m_pView;
}

that executes 
CXTPPropertyGridView::ResetContent() that contains the instruction 
CFont* pFont =  &GetPaintManager()->GetItemMetrics()->m_fontNormal ;

PaintManager is still a valid object, but m_pMetrics in it is no more valid thus is not correct to access it to get 
m_fontNormal

for this reason 
pFont is not assigned correctly and when 
CXTPPropertyGridView::ResetContent() executes the successive instruction 
SetFont(pFont, FALSE);
 makes the application to crash.

This is what I've been able to trace about my Application crash.
Now the question: am I someway wrong in deleting PropertyGrid or is this a bug that has been solved in latest release (I'm actually using 9.81 ToolkitPro).

Thanks for any help
Paolo
