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...

XmStringTableToXmString(library call)									     XmStringTableToXmString(library call)

NAME
XmStringTableToXmString -- A convenience function that converts a compound string table to a single compound string SYNOPSIS
#include <Xm/Xm.h> XmString XmStringTableToXmString( XmStringTable table, Cardinal count, XmString break_component); DESCRIPTION
XmStringTableToXmString takes as input table of compound strings and a specified string component (such as a tab) and returns a single com- pound string consisting of each of the elements of table concatenated together with a single copy of break_component inserted between each element. table Specifies an XmStringTable containing the compound strings to be converted. count Specifies the number of compound strings in table. break_component Specifies the XmStringComponent that will be inserted in the result to separate the individual elements of table. The most useful types will be XmSTRING_COMPONENT_SEPARATOR and XmSTRING_COMPONENT_TAB. Refer to the XmStringComponentType(3) reference page for a complete list of possible component types. Note, however, that the XmSTRING_COMPONENT_UNKNOWN component is not a possible type. RETURN
Returns a new XmString. The function will allocate space to hold the returned compound string. When the application no longer needs the returned compound string, the application should call XmStringFree. RELATED
