Process terminated with status 3

[Slyde]

Just checking out wxWidgets3.1.4 because I was told "a lot of work" had been done to the wxGrid.

So I created a small frame-based app and set a grid (10 cols x 12 rows) on it in hopes of seeing alternate colors for the grid rows. When I saw nothing for that, I opened the griddemo.cpp sample and looked at the SetRowAttr(). I copied it over to my file and changed it a little:

Code: Select all

wxGridCellAttr *attr;
    attr = new wxGridCellAttr;
    attr->SetTextColour(*wxBLUE);
    Grid1->SetColAttr(5, attr);
    attr = new wxGridCellAttr;
    attr->SetBackgroundColour(wxColour( 255, 232, 255, wxALPHA_TRANSPARENT));
    for(int i{}; i +1 <= 10; ++i){
        if(i % 2){
            Grid1->SetRowAttr(i, attr);
        }
    }

It works fine. I can access the Menu items (the stock ones: Quit and About) and they work as expected. But when I close the app, I get various termination messages. One of them is in the title here. Another is Process terminated with status -1073740940. Can someone tell me why this is?

Thanks.

This is on Win X using Code::Blocks.

UPDATE: For some reason, the problem seems to occur only when Grid1->SetRowAttr(i, attr); is called repetitively. I changed the above code to call it only once and all was fine. However, even calling it twice brought back the status codes again. I'll get it to point where data is being put in the grid and see what happens when I color alternate lines on it.

From the documentation for wxGrid::SetAttr()

Sets the cell attributes for the specified cell.
The grid takes ownership of the attribute pointer.

If you use the same pointer multiple times, you need to increase its reference counter.

Try calling wxGridCellAttr::IncRef()

BTW:

Process terminated with status -1073740940

Error messages like this are usually useless. Next time please run your app in debug mode and provide a call stack.
