Hi everyone.
I have been trying to write a sample code for embedding mozilla in
wxWidgets.
I dont seem to be able to embed Mozilla even though i follow all the steps
given in http://developer.mozilla.org/en/docs/XPCOM_Glue and
http://developer.mozilla.org/en/docs/GRE
I am running Ubuntu 8.04.
Code:
#include "wx/wxprec.h"
#ifdef __BORLANDC__
#pragma hdrstop
#endif
#ifndef WX_PRECOMP
#include "wx/wx.h"
#endif
#define XPCOM_GLUE
#include "xpcom-config.h"
#include "nsXPCOMGlue.h"
#include "nsDebug.h"
#include "nsCOMPtr.h"
#include "widget/nsIBaseWindow.h"
#include "nsILocalFile.h"
#include "nsIWebBrowser.h"
#include "docshell/nsIWebNavigation.h"
#include "nsEmbedCID.h"
#include "nsEmbedString.h"
#include "xulapp/nsXULAppAPI.h"
#include "nsComponentManagerUtils.h"
#define wxCSTR wxString::FromAscii
XRE_InitEmbeddingType XRE_InitEmbedding;
XRE_TermEmbeddingType XRE_TermEmbedding;
class MyApp : public wxApp
{
public:
virtual bool OnInit();
};
class MyFrame : public wxFrame
{
public:
MyFrame(const wxString& title);
void OnQuit(wxCommandEvent& event);
void OnAbout(wxCommandEvent& event);
private:
DECLARE_EVENT_TABLE()
};
enum
{
Minimal_Quit = wxID_EXIT,
Minimal_About = wxID_ABOUT
};
BEGIN_EVENT_TABLE(MyFrame, wxFrame)
EVT_MENU(Minimal_Quit, MyFrame::OnQuit)
EVT_MENU(Minimal_About, MyFrame::OnAbout)
END_EVENT_TABLE()

bool MyApp::OnInit()
{
if ( !wxApp::OnInit() )
return false;
MyFrame *frame = new MyFrame(wxCSTR("Minimal wxWidgets App"));
SetTopWindow(frame);
frame->Show(true);
nsCOMPtr<nsIBaseWindow> baseWindow;
nsCOMPtr<nsIWebBrowser> webBrowser;
nsCOMPtr<nsILocalFile> libxul;
nsCOMPtr<nsILocalFile> appDir;
nsCOMPtr<nsIWebNavigation> webNavigation;
nsDynamicFunctionLoad nsFuncs[] = { {"XRE_InitEmbedding",

nsresult rv;
rv = XPCOMGlueStartup("/home/raravi/xulrunner-sdk/bin/libxpcom.so");
if (NS_FAILED(rv))

PR_FALSE, getter_AddRefs(appDir));
if(NS_FAILED(rv))
{
printf("NS_NewNativeLocalFile\n");
}
rv = XRE_InitEmbedding(libxul, appDir, 0, 0, 0);
if (NS_FAILED(rv))
{
printf("XRE_InitEmbedding\n");
}
webBrowser = do_CreateInstance(NS_WEBBROWSER_CONTRACTID, &rv);
if (NS_FAILED(rv))
{

}

nsIWebNavigation::LOAD_FLAGS_NONE, 0, 0, 0);
if (NS_FAILED(rv))
{
printf("LoadURI\n");
}
return true;
}
MyFrame::MyFrame(const wxString& title)
: wxFrame(NULL, wxID_ANY, title)
{
wxMenu *fileMenu = new wxMenu;
wxMenu *helpMenu = new wxMenu;
wxMenuBar *menuBar = new wxMenuBar();
helpMenu->Append(Minimal_About, wxCSTR("&About...\tF1"), wxCSTR("Show
about dialog"));
fileMenu->Append(Minimal_Quit, wxCSTR("E&xit\tAlt-X"), wxCSTR("Quit this
program"));
menuBar->Append(fileMenu, wxCSTR("&File"));
menuBar->Append(helpMenu, wxCSTR("&Help"));
SetMenuBar(menuBar);
CreateStatusBar(2);
SetStatusText(wxCSTR("Welcome to wxWidgets!"));
}
void MyFrame::OnQuit(wxCommandEvent& WXUNUSED(event))
{
XRE_TermEmbedding();
XPCOMGlueShutdown();
Close(true);
}
void MyFrame::OnAbout(wxCommandEvent& WXUNUSED(event))
{
wxMessageBox(wxCSTR("This is the minimal wxWidgets sample\n"),
wxCSTR("About wxWidgets minimal sample"),
wxOK | wxICON_INFORMATION,
this);
}
This code compiles and runs successfully. But when run, i dont see the
embedded mozilla window...:-(
Its as if i am running a normal wxWidgets app. What am i doing wrong?
These are the cmds i use.
g++ `wx-config --cppflags` -fshort-wchar -c -g
-I/home/raravi/xulrunner-sdk/sdk/include
-I/home/raravi/xulrunner-sdk/include -o
build/Debug/GNU-Linux-x86/_ext/home/raravi/NetBeansProjects/wxXULTest/wxXULTest.o
/home/raravi/NetBeansProjects/wxXULTest/wxXULTest.cpp
g++ `wx-config --cppflags` -fshort-wchar `wx-config --libs` -o
dist/Debug/GNU-Linux-x86/wxxultest
build/Debug/GNU-Linux-x86/_ext/home/raravi/NetBeansProjects/wxXULTest/wxXULTest.o
/home/raravi/xulrunner-sdk/lib/libxpcomglue.a
Any help would be greatly appreciately.
