/*
|
|
|
|
wxDllWidget can be used to embed a wxWindow implemented in C++ in your
|
|
wxPython application without the need to write a SWIG interface. Widget's code
|
|
is stored in shared library or DLL that exports DLL_WidgetFactory symbol
|
|
and loaded at runtime. All you have to do is to pass the name of DLL and the class
|
|
to create to wxDllWidget's ctor.
|
|
|
|
Runtime-loadable widget must have HandleCommand method (see the example) that is
|
|
used to communicate with Python app. You call wxDllWidget.SendCommand(cmd,param) from
|
|
Python and it in turn calls HandleCommand of the loaded widget.
|
|
|
|
You must use DECLARE_DLL_WIDGET, BEGIN_WIDGET_LIBRARY, END_WIDGET_LIBRARY and
|
|
REGISTER_WIDGET macros in your C++ module in order to provide all the meat
|
|
wxDllWidget needs.
|
|
|
|
Example of use:
|
|
|
|
#define CMD_MAKEWHITE 1
|
|
|
|
class MyWindow : public wxWindow
|
|
{
|
|
public:
|
|
MyWindow(wxWindow *parent, long style)
|
|
: wxWindow(parent, -1) {}
|
|
|
|
int HandleCommand(int cmd, const wxString& param)
|
|
{
|
|
if (cmd == CMD_MAKEWHITE)
|
|
SetBackgroundColour(*wxWHITE);
|
|
return 0;
|
|
}
|
|
};
|
|
DECLARE_DLL_WIDGET(MyWindow)
|
|
|
|
class MyCanvasWindow : public wxScrolledWindow
|
|
{
|
|
...
|
|
};
|
|
DECLARE_DLL_WIDGET(MyCanvasWindow)
|
|
|
|
BEGIN_WIDGET_LIBRARY()
|
|
REGISTER_WIDGET(MyWindow)
|
|
REGISTER_WIDGET(MyCanvasWindow)
|
|
END_WIDGET_LIBRARY()
