Hi!
I have a simple programm call:
....
TGTextButton *draw = new TGTextButton(hframe, "&Draw");
draw->Connect("Clicked()", "MyMainFrame",this, "DoDraw()");
.... 
where function DoDraw() is:
void MyMainFrame::DoDraw(){
    TF1 *f1 = new TF1("f1", "sin(x)/x", 0, gRandom->Rndm()*10);
    f1->SetFillColor(19);
    f1->SetFillStyle(1);
    f1->SetLineWidth(3);
    f1->Draw();

    TCanvas *fCanvas = fEcanvas->GetCanvas();
    fCanvas->cd();
    fCanvas->Update();
}
Compiling and linking of this programm is sucesfull, but when i it runs
and i try to press "draw" button by mouse, i see:
Error in <TQObject::CheckConnectArgs>: slot DoDraw() does not exist.

However when i run it interactive session it works propertly.

My system: Linux - Red Hat 6.2 
           root version - 3.03.09
 

Thank you.
