Problem with Sizer initialize when using XRC

In DB (v 4.08) one can assign a member variable name to a Sizer (let
us say m_MySizer), but when using XRC files this member is not
initialized.

There is for example a

wxBoxSizer* m_MySizer;

in the header file and there is a

m_MySizer = NULL;

in the MyApp::Init()

but nothing else.

Consequently any m_MySizer->Add(...) crashes the program.

I added something like this to the MyApp::Init()

m_MySizer = (wxBoxSizer *) m_MyPanel->GetSizer();

but would have expected that DB would do that.

Suggestions welcome,

Cees.

Hi,

The problem is that in general you can't retrieve a specific sizer from
an XRC hierarchy (they're not named), so I'm not sure how DB would
really do this. Getting the top-level sizer as you suggest would only be
a partial solution.

Julian

I don't think he's necessarily talking about getting the top-level
sizer. I've been picking a control that's directly contained by the
sizer and calling GetSizer() on it to set the variable that's defined
in DB. It works fine manually, but it would be nice if DB could do
it.

I'm confused - surely wxWindow::GetSizer() returns that window's
top-level sizer, rather than a sizer that contains that window?

(By top-level sizer I mean the sizer that's a child of any given window
that does its own sizer layout, not one sizer per whole dialog.)

Julian

Oops. I do GetContainingSizer() on a control, which does what I said. :-}
