wxFileDialog was not declared in this scope error Topic is solved

[Hossein]

hello all, sth stranged happened to me , i wrote an event handler , it was working , now its not , and it kept giving me an stupid errors!

Code: Select all

void _2Frame::OpenFile(wxCommandEvent& WXUNUSED(event))
{
	wxFileDialog *OpenDialog = new wxFileDialog(this, _("Choose a file to open"), wxEmptyString, wxEmptyString,_("Text files (*.txt)|*.txt|C++ Source Files (*.cpp, *.cxx)|*.cpp;*.cxx|C Source files (*.c)|*.c|C header files (*.h)|*.h"),	wxFD_OPEN, wxDefaultPosition);

	// Creates a "open file" dialog with 4 file types
	if (OpenDialog->ShowModal() == wxID_OK) // if the user click "Open" instead of "cancel"
	{
		CurrentDocPath = OpenDialog->GetPath();

		// Sets our current document to the file the user selected
		TextCtrl1->LoadFile(CurrentDocPath); //Opens that file
		// Set the Title to reflect the  file open
		 OpenDialog->GetFilename();
		 //SetTitle(wxString(("Edit - "))<<
	}
}

the irony is that i have two copies from the project! one of them compiles well! but another one doesnt! why! they are all the same , just the same!!
what is the cause?

are you including <wx/filedlg.h> with all of your other #includes?

[Hossein]

no! is it the cause?
because if it is , why the other instance of the project compiles!?that is the same as this one that gives error!

Whenever you use a class, import its header. It's possible in some cases you don't need to because another header you included included it, so it was included indirectly and implicitely. It's best to not rely on that and include everything you need explicitely (except for some base classes e.g. wxString which are included by wx/wx.h on all platforms)
