wxWindows

I'm trying to figure out, how to use wxWindows library. I want to create just simple application, that'll display selected image.
this is part of the code, that creates open file dialog and shoul display image into the frame....

Code:

void testFrame::OnOpen(wxCommandEvent& WXUNUSED( event) )
{
	wxFileDialog *fileDialog = new wxFileDialog(this, "Vyber subor", "", "", "*.*", wxOPEN, wxDefaultPosition);
	if( fileDialog->ShowModal() == wxID_OK)
	{
		//tak treba osetrit open
		wxBitmap *bitmap = new wxBitmap();
		bitmap->LoadFile(fileDialog->GetPath(), wxBITMAP_TYPE_XPM);
		if(bitmap == false)
		{
			wxMessageBox( wxT("Nepodarilo sa otvorit subor s obrazkom"), wxT("CHYBA"), wxOK|wxICON_ERROR, this);
			bitmap->~wxBitmap();
			return;
		}
		wxMessageBox( wxT("Obrazok by mal byt nacitany"), wxT("Subor OK"), wxOK|wxICON_INFORMATION, this);
		this->staticBitmap->SetBitmap(bitmap); 
	}
	fileDialog->Destroy();
}

but when I try to compile, I get an error message:

Code:

*/home/psycho/myprogs/test/src/test.cpp:97: error: no matching function for call to `wxStaticBitmap::SetBitmap(wxBitmap*& )' 
*/usr/include/wx/gtk/statbmp.h:44: error: candidates are: virtual void wxStaticBitmap::SetBitmap(const wxBitmap& )

what am I doing wrong?

going by that error, not defining your bitmap pointer as a const

Code:

		//tak treba osetrit open
		const wxBitmap *bitmap = new wxBitmap();

no, I got one more error then

Code:

*/home/psycho/myprogs/test/src/test.cpp:88: error: passing `const wxBitmap' as `this' argument of `bool wxBitmap::LoadFile(const wxString&, int)' discards qualifiers 
*/home/psycho/myprogs/test/src/test.cpp:97: error: no matching function for call to `wxStaticBitmap::SetBitmap(const wxBitmap*&)' 
*/usr/include/wx/gtk/statbmp.h:44: error: candidates are: virtual void wxStaticBitmap::SetBitmap(const wxBitmap&)

right, ok so you are providing a pointer when it wants the direct object. I suck at pointers, but try either declaring as "const wxthiny bitmap" or dereference the pointer when you pass it- "SetBitmap(&bitmap)" don't blame me if that's wrong though! i'm a perl chap.

What command are you using to compile? Are you telling the linker to link to the right library?

SDL

look at my sig for the link

(don't you guys just hate me?
