Top Forums Programming "Blocking" message box in Motif Post 302297365 by Zipi on Friday 13th of March 2009 07:10:44 AM

By the way....before you wonder about modality Smilie

I need this blocking capability because what i need is:
1)i want to copy/transfer several selected files to another location
2)if a file with the same name exists on the destination path,the application will popup the classic question dialog asking if the user wants to replace the file or not

What i am actually doing is:
1)i use a XmList containing the files in the source path
2)when the user selects the "copy" button i do the following:
Code:
XmString *sTable;
XmString askedQuestion;
char question[256];

int cnt;
char* selectedFile;
XmString *strlist;
       XtVaGetValues(_logEventFileList,XmNselectedItemCount,&cnt,XmNselectedItems,&strlist,NULL);

cout<<"selected "<<cnt<<" elements"<<endl;

//For each selected file popup a question dialog (which is the member variable _dialogConfirm)
while(cnt--)
{
      if(!(selectedFile=(char *)XmStringUnparse(strlist[cnt],
                                              XmFONTLIST_DEFAULT_TAG,
                                              XmCHARSET_TEXT,
                                              XmCHARSET_TEXT,
                                              NULL,0,
                                              XmOUTPUT_ALL)))
      break;
      cout<<selectedFile<<endl;

      //Not performing the check if the file exists on the destination right now
      //Just trying to make a dialog appear for each selected file
      sprintf(question,"A file named %s already exists./n/nWhat do you want to do?",selectedFile);
      askedQuestion=XmStringCreateLocalized (question);            
      XtVaSetValues(_dialogConfirm, XmNmessageString, askedQuestion,NULL);

      XtManageChild(_dialogConfirm);
      XmStringFree(askedQuestion);
}
XtUnmanageChild(_dialogConfirm);

As you can see,i tried to do it with XtManageChild,but it returns immediately,so i don't see any dialog.
So,making the dialog modal doesn't help me...
