So I created a wrapper class to enable the form builder to create an
a2dDocumentFrame instead of a wxFrame, and it seems to have fixed the
crashing-on-exit with respect to the dragging tool. However, the
world-preview view still does not get drawn correctly at startup. Is
there any way to force a post-layout re-render or something of that
sort to get it to redraw the contents, or a view invalidation?
I'll also take a look at the classes you suggested for implementing
the hand tool among other things, thanks for the pointers.
Do you think in the future there could be a wxFrame-compatible
constructor for the a2dDocumentFrame? That way I wouldn't need to use
a wrapper at all, and people could build interfaces directly using
a2dDocumentFrame in wxFormBuilder. It really makes the interface
design aspect a lot easier. It'd be really great if there were native
widgets that could be placed into the interface in wxFormBuilder, but
that'd be a pain to compile for it. Here's the wrapper class I used
if anyone is interested. Unfortunately, it makes some assumptions
about how the frame is initialized:
Header ("wxFrameA2D.h"):
#pragma once
#include "docview/include/docviewref.h"
class wxFrameA2D :
public a2dDocumentFrame
{
public:
wxFrameA2D
(
wxWindow * parent,
wxWindowID id,
const wxString & title,
const wxPoint & position
= wxDefaultPosition,
const wxSize & size
= wxDefaultSize,
long style
= wxDEFAULT_FRAME_STYLE,
const wxString & name
= "frame",
bool parentFrame
= true,
a2dView * view
= NULL
);
~wxFrameA2D();
};
Implementation ("wxFrameA2D.cpp"):
#include "wxFrameA2D.h"
wxFrameA2D::wxFrameA2D
(
wxWindow * parent,
wxWindowID id,
const wxString & title,
const wxPoint & position,
const wxSize & size,
long style,
const wxString & name,
bool parentFrame,
a2dView * view
) :
a2dDocumentFrame
(
parentFrame,
NULL,
view,
id,
title,
position,
size,
style,
name
)
{
}
wxFrameA2D::~wxFrameA2D()
{
}
