Hello,
try to rewrite your macros in one file tdgtest.C as:
------------- tdgtest.C -------------------
#include <stdio.h>
int tbut(Int_t ilayer)
{
printf("ilayer= %d\n",ilayer);
return 0;
}
void tdgtest()
{
TDialogCanvas *dialog = new TDialogCanvas("dialog","",700,780);
TButton *but = new TButton("test","tbut(0);",.05,.8,.95,.88);
but->Draw();
}
------------- cut here -------------------
Happy ROOTing
Radovan
