wxGridCellAttr::Clone() access violation
Posted: Thu Aug 02, 2018 4:41 pm
Running in the debugger with Visual Studio 2010, wxWidgets version 3.1.0.
I get an access violation cloning wxGridCellAttr.
I've got a temporary work-around creating wxGridCellAttr object from scratch, but it seems like I should be able to start with default attributes then change those to what I want. Also access violation on ->Clone() seems odd.
My only goal is to successfully call wxGrid's SetColAttr() function with over-ridden defaults. (setting attributes on every cell was too slow)
I get an access violation cloning wxGridCellAttr.
Code: Select all
wxGrid* pGrid = new wxGrid(this, ID_GRID_MYCUSTOMID, wxDefaultPosition, wxSize(200,250));
pGrid->CreateGrid(1,12); // I always do this early to avoid problems with missing initialization
wxGridTableBase* pBaseTable = pGrid->GetTable();
wxGridCellAttrProvider* pAttrProv = pBaseTable->GetAttrProvider();
wxGridCellAttr* pAttr1 = pBaseTable->GetAttr(0,0,wxGridCellAttr::Col);
// access violation occurs trying to clone default attributes:
wxGridCellAttr* pAttr3 = pAttr1->Clone();
// another access violation trying to read from provider directly:
wxGridCellAttr* pAttr2 = pAttrProv->GetAttr(0,0,wxGridCellAttr::Col);My only goal is to successfully call wxGrid's SetColAttr() function with over-ridden defaults. (setting attributes on every cell was too slow)
