[Dev-C++] wxwindows

[Carlos d. M. <cg...@wo...>]

Hi:
I downloaded wxwindows from its home page, and now I am having trouble
for compile a simple hello demo, I got a great amount of linker errors I
don't see how to solve, I sent this message to wxwindows mailing list
and in that archive I don't find the solution. Thinking there can be
somebody who uses wxwindows but is not in its mailing list, I write this
here, too:
I used as project options either console and windows application, but
the errors are the same.

The code of the hello demo:

/*
 * hworld.cpp
 * Hello world sample by Robert Roebling
 */

#define __GNUWIN32__ //two underscores before, two after the word. You
have to include them in the demo
#define __WXMSW__    //code. They are not in the sample due to...[tired
of writing]
#define UNICODE //It is defined in the demo
#include "wx/wx.h"

class MyApp: public wxApp
{
    virtual bool OnInit();
};

class MyFrame: public wxFrame
{
public:

    MyFrame(const wxString& title, const wxPoint& pos, const wxSize&
size);

    void OnQuit(wxCommandEvent& event);
    void OnAbout(wxCommandEvent& event);

    DECLARE_EVENT_TABLE()
};

enum
{
    ID_Quit = 1,
    ID_About,
};

BEGIN_EVENT_TABLE(MyFrame, wxFrame)
    EVT_MENU(ID_Quit, MyFrame::OnQuit)
    EVT_MENU(ID_About, MyFrame::OnAbout)
END_EVENT_TABLE()

IMPLEMENT_APP(MyApp)

bool MyApp::OnInit()
{
    MyFrame *frame = new MyFrame( "Hello World", wxPoint(50,50),
wxSize(450,340) );
    frame->Show(TRUE);
    SetTopWindow(frame);
    return TRUE;
}

MyFrame::MyFrame(const wxString& title, const wxPoint& pos, const
wxSize& size)
: wxFrame((wxFrame *)NULL, -1, title, pos, size)
{
    wxMenu *menuFile = new wxMenu;

    menuFile->Append( ID_About, "&About..." );
    menuFile->AppendSeparator();
    menuFile->Append( ID_Quit, "E&xit" );

    wxMenuBar *menuBar = new wxMenuBar;
    menuBar->Append( menuFile, "&File" );

    SetMenuBar( menuBar );

    CreateStatusBar();
    SetStatusText( "Welcome to wxWindows!" );
}

void MyFrame::OnQuit(wxCommandEvent& WXUNUSED(event))
{
    Close(TRUE);
}

void MyFrame::OnAbout(wxCommandEvent& WXUNUSED(event))
{
    wxMessageBox("This is a wxWindows Hello world sample",
        "About Hello World", wxOK | wxICON_INFORMATION, this);
}

THe linker errors:

I suspect I shall add some library, but I don't find what, I proved with
-lwx -lpjeg -lxpm[...] -lolexxx... but the errors remain there.

Thanks.

I decided give a try to wxwindows 233, what I achieve is that when I use
msys ./configure, it says checking for flex... lex, after make it
arrives a point when it pass over lexer.1 and says lex: command not
found.
With cmd.exe make -f makefile.g95 makedir cannot create dirs and cpy
cannot copy (file does not exist)
With msys make it starts to compile till a notebook.cpp, where it
reports a lot of errors: undefined variables and parse errors.

(bonjour,)
hello,


You could find in your dev-c++ directory a new folder docs with various 
files. The most important is  wx.chm file.
Zero : read "topics overview"->
*Notes on using the reference* <wx450.htm#referencenotes>
*Writing a wxWindows application: a rough guide* <wx451.htm#roughguide>
*wxWindows Hello World sample* <wx452.htm#helloworld>
*wxWindows samples* <wx453.htm#samples>
*wxApp overview* <wx454.htm#wxappoverview>

First create a new wxwindows project and read the comments.
Second compile it click on the classes tab : you now have the list off 
all the classes of the project .
You could also add in the editor properties->completion the file 
include\wx\wx.h (very useful).

you can create a button add
   wxButton *toto= new wxButton(frame, 2, "this is a test");
   toto->SetBackgroundColour(wxColour(120,0,0));

just after :
---------
bool MyApp::OnInit()
{
    // create the main application window
    MyFrame *frame = new MyFrame(_T("Minimal wxWindows App"),
                                 wxPoint(50, 50), wxSize(450, 340));
-------------

this way is not the best, but it's very simple.

You could download wxwindows for windows at :
http://prdownloads.sourceforge.net/wxwindows/wxMSW-2.4.0-setup.zip

In the samples directory you will find a lot of examples

and
http://prdownloads.sourceforge.net/wxwindows/wxWindows-2.4.0-WinHelp.

for the winhelp file that you can add to the dev-cpp help menu.

finaly, if you want build complex apps use the xrc contrib (that should 
be in the main library soon). To edit xrc files I am using xrced 
provided with wxPython.

bye
