wxErlang error message

Question

I cannot get wxErlang to work at all. Do i need to include a module. Can't find any basic information relating to it. Please help. I am look for a very basic example of a module.

the error I am getting is

undefined function wx:start/0

Answer 1

I just needed to include the wx lib using the following line

-include_lib("include/wx.hrl").

include/ is a sub directory in my project containing the wx library.

Answer 2

This should display an empty frame:

1> wx:new().
{wx_ref,0,wx,[]}

2> Frame = wxFrame:new(wx:null(), 0, "myFrame").
{wx_ref,36,wxFrame,[]}

3> wxFrame:show(Frame).
true

Answer 3

To find the ex-erlang-samples You should issue the following call in EShell to locate the base directory for wx-erlang:

code:lib_dir(wx).

On Windows the returned path uses "/" instead of "\", so just replace them.

Inside that directory there shoud be a directory "examples". Start with "simple" inside those examples.

Also You should check if wx is working properly: use

wx:demo().

in EShell.
