Title: invalid use of undefined type `struct wxRadioBox'|
Post by: samsam598 on August 12, 2009, 11:43:52 am
Greeting to everybody!

I am using C::B + wxSmith to learn wxWidgets programming.I met a problem that wxRadioBox does not work properly,or wxSmith does not generate xrc file properly,I don't know anyway...

Some background:
** wxWidgets 2.9rc6+MinGW3.4.5 +C::B nightly build5716 under Windows XP
** Using wxSmith to design a wxDialog (MyDialog),put a wxRadionBox on it,ID:ID_RADIOBOX1, var name:rbChoice;
** Within rbChoice added 2 choices :Classic | Extra;
** Added a button on the dialog to test .

Code

MyDialog:MyDialog(wxWindow* parent)
{
	//(*Initialize(MyDialog)
	wxXmlResource::Get()->LoadObject(this,parent,_T("MyDialog"),_T("wxDialog"));

	//some other controls...

	Button1 = (wxButton*)FindWindow(XRCID("ID_BUTTON1"));
	rdChoice = (wxRadioBox*)FindWindow(XRCID("ID_RADIOBOX1"));
	

	Connect(XRCID("ID_BUTTON1"),wxEVT_COMMAND_BUTTON_CLICKED,(wxObjectEventFunction)&DForm::OnTestButtonClick);
}

void MyDialog::OnTestButtonClick(wxCommandEvent& event)
{
    int choice= rbChoice->GetSelection();
    switch( choice)
{
    case 0:
     wxMessageBox(_T("Classic"));
    break;
   case 1:
    wxMessageBox(_R("Extra"));
    break;

}

When I compile under C::B,got below errors:

F:\CodeBlocksProject\usesqliteApp\DForm.cpp|393|error: invalid use of undefined type `struct wxRadioBox'|
E:\wxWidget30\include\wx\msw\window.h|34|error: forward declaration of `struct wxRadioBox'|

I don't know why,but I tested under wxDev-Cpp almost the same stuff.it is OK.

Could anybody here figure me out what's going one here?
Thanks in advance.

Best Regards,
Sam

Do you have the include for the wxRadioBox class?

See here http://docs.wxwidgets.org/stable/wx_wxradiobox.html what do you need (you show check the docs for your version of wx thought)

Yes.I did.I re-implemented the UI by changing not to  generate xrc file this time and the problem is solved temporarily.

Thanks and regards,
