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...

XmCreateTemplateDialog(library call)									      XmCreateTemplateDialog(library call)

NAME
XmCreateTemplateDialog -- A MessageBox TemplateDialog convenience creation function SYNOPSIS
#include <Xm/MessageB.h> Widget XmCreateTemplateDialog( Widget parent, String name, ArgList arglist, Cardinal argcount); DESCRIPTION
XmCreateTemplateDialog is a convenience creation function that creates a DialogShell and an unmanaged MessageBox child of the DialogShell. The MessageBox widget's XmNdialogType resource is set to XmDIALOG_TEMPLATE. By default, the TemplateDialog widget contains only the separa- tor child. You can build a customized dialog by adding children to the TemplateDialog. You can create the standard MessageBox pushbuttons, Cancel, Help, and OK, by specifying the associated callback and label string resources. Setting XmNsymbolPixmap or XmNmessageString creates a symbol or message label. Use XtManageChild to pop up the TemplateDialog (passing the MessageBox as the widget parameter); use XtUnmanageChild to pop it down. XmCreateTemplateDialog forces the value of the Shell resource XmNallowShellResize to True. parent Specifies the parent widget ID name Specifies the name of the created widget arglist Specifies the argument list argcount Specifies the number of attribute/value pairs in the argument list (arglist) For a complete definition of MessageBox and its associated resources, see XmMessageBox(3). RETURN
Returns the MessageBox widget ID. RELATED
