1. Unable to add image handler

#3321

Posted by: 2004-02-07 02:10:53

I have been unable to successfully add an image handler. I'm sure it isn't that difficult, but I just cant seem to get it to work.

This is the code I've been trying to compile:


bool MainApp::OnInit()
{
wxImage Pic_Splash; // Create an image variable

Pic_Splash.AddHandler(wxGIFHandler);

if (Pic_Splash.LoadFile("bitmaps\\splash.gif", wxBITMAP_TYPE_GIF)) // If the bitmap loads, show the splash screen
{
      new wxSplashScreen(Pic_Splash,
          wxSPLASH_CENTRE_ON_SCREEN|wxSPLASH_TIMEOUT,
          6000, NULL, -1, wxDefaultPosition, wxDefaultSize,
          wxSIMPLE_BORDER|wxSTAY_ON_TOP);
}
// Create the window
MainFrame *MainWin = new MainFrame("BlakkCount", wxPoint(1, 1),
wxSize(290, 190)); // Create an instance of our frame, or window
MainWin->Show(TRUE); // show the window
SetTopWindow(MainWin);// and finally, set it as the main window

return TRUE;
}

Thanks in advance

Dev-C++ gives a "parse error before ')'" on the line with

 Pic_Splash.AddHandler(wxGIFHandler);

Hi!
1. Be sure to have <wx/image.h> image included, so that gcc won't complain about that parse error (normally this points to some unknown class name).
2. Use Pic_Splash.AddHandler(new wxGIFHandler);, because the parameter should be a pointer to an image handler.

If it was hard to write, it should be hard to read!- Do. Or do not. There is no try!

5. Thanks

it's really just a simple mistake, you have an extra ")" in your line "wxSize(290, 190);" It shows the parse error where it is because it's the first line in your code with a "(". Just a simple typo.BlakkSyn wrote:
