Message1. wxSplashscreen class question
#3124
Posted by: 2003-12-27 04:46:47
Hi,

I've just installed wxWindows for Dev-C++, and i must say it's a great program. Good work! Anyway, i've got a question about a splashscreen i'm trying to use. I'm looking at this reference:

http://www.wxwindows.org/manuals/2.4.2/wx355.htm#wxsplashscreenwxsplashscreen

And now i need to paste this somewhere:

  wxBitmap bitmap;
  if (bitmap.LoadFile("splash16.png", wxBITMAP_TYPE_PNG))
  {
      wxSplashScreen* splash = new wxSplashScreen(bitmap,
          wxSPLASH_CENTRE_ON_SCREEN|wxSPLASH_TIMEOUT,
          6000, NULL, -1, wxDefaultPosition, wxDefaultSize,
          wxSIMPLE_BORDER|wxSTAY_ON_TOP);
  }
  wxYield();

Where do i put it?
Thanks in advance, ow andum, Merry Christmas!!

Hmm, i just realised that i downloaded the Dev-C++ package only.. is that enough to get the entire wxWindows stuff? I'm now downloading the full 13 mb package. Samples should be included there.

Hi!
What you get and what works depends on which devpak you downloaded. The samples are included in the full pack from the wxWindows site, but this is a source release so you will have to compile it yourself (which I'd advise you to do). The devpak I released so time ago should contain the code for the samples too. If you need the contribs, they are in a different devpak.
You should be able to compile every wxWindows stuff with the devpaks though. The only diference is that the devpak contains the precompiled lib, not the the complete sources.

About you problem: Well, copy&paste it where it makes sense :)
If you want a splashscreen on startup, do it in the contructor of you main window for example. Be sure to link libpng.a in for PNG support.

Is there a splashscreen sample somewhere? I want it to first show the splashscreen and then continue with a wizard. Sounds complicated to me :S
Thanks in advance,

Hi!
Nope, it's not complicated :)
Call the splashscreen either from your main app entry point or from the constructor of the wizard. That way the splashscreen will be shown, it times out and the initialisation continues.
I guess you don't need to call wxYield(). Since the splashscreen is timed it will destroy itself once the time is over.

Would you mind attaching a working version of a wizard that NOT launches a window, just the wizard. Sorry i can't get it to work.

Hi!
Sorry, but now I'm at a loss... What exactly do you want to do?

"Would you mind attaching a working version of a wizard that NOT launches a window, just the wizard."
Judging from the code sample you send the only thing your app could do is to show a splashscreen and then... nothing!
If you want a wizard to show up, you should create an instance of one in OnInit() and maybe call SetTopWindow(myWizard).
You must call RunWizard() either from OnInit() or in the ctor of the wizard. Be sure to call Destroy() for the wizard.

If you don't want to launch "a window" (the splashscreen I presume), just don't contruct it...

Omg sorry, i'm asking two things which should be one :S Eh.. basically what i want is a splashscreen with a wizard. But i haven't got a clue to do that. I'll see what i can cum up with. sorry for the confusion.

Hi!
When I find the time later this day, I'll hack a little example that creates a wizard and shows a splashscreen before the wizard gets created. That's what you want, right? A simple "hello, about, version" splashscreen and then your killer app :)

Hi!

Sorry, had no time yesterday...
Here's a small example that loads a bitmap file, shows a splashscreen and then runs a wizard. 

#include <wx/wxprec.h>
#ifndef WX_PRECOMP
   #include <wx/wx.h>
#endif
#include <wx/wizard.h>
#include <wx/image.h>
#include <wx/splash.h>

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

IMPLEMENT_APP(MainApp)

bool MainApp::OnInit()
{
    wxInitAllImageHandlers();

    wxBitmap logo;
    logo.LoadFile("logo.bmp",wxBITMAP_TYPE_BMP);
    
    wxWizard* wizard = new wxWizard(NULL,-1,"Test");
    wxWizardPageSimple* m_page1 = new wxWizardPageSimple;
    
    wxSplashScreen* splash = new wxSplashScreen(logo,
          wxSPLASH_CENTRE_ON_SCREEN|wxSPLASH_TIMEOUT,
          6000, wizard, -1, wxDefaultPosition, wxDefaultSize,
          wxSIMPLE_BORDER|wxSTAY_ON_TOP);

    wizard->RunWizard(m_page1);
    wizard->Destroy();                                       

    return true;
}

Not much in there. You'll need to add your pages to the wizard. Be sure to call Destroy() for the wizard if you don't want you app to "hang".

Hi!
Open you project settings. Got to the "Parameters" tab and enter the lines I posted below the others that should be there (like -lwxmsw etc.).
Close the settings and compile again. The error is that for wxInitAllImageHandlers(); you'll need all image processing libs linked in.

Hi,

I've followed alone, because I had the same problems.

After following the above directions, I now link, but get an error about

    jpeg-62.dll

not being found and then all the paths that it has looked in.

I did a search and found the file in:

  c:Program FilesCommon FilesGTK2.0lib

so, I tried adding this directory to the lib search path, but this did not work.

Any other ideas?

Thanks, Patrick

Hi,

Besides using wxInitAllImageHandlers(), you could also use this:

wxImage::AddHandler( new wxPNGHandler );

This will only add the PNG handler.

Best Regards,
Yeoh
