Description
This simple utility class can be used to display a simple message to the user. The utility displays the message, and then waits for the user to enter to press Yes, No, or Cancel.
New Methods
vYNReplyDialog(vBaseWindow* win)
vYNReplyDialog(vApp* app)
The vYNReplyDialog constructor requires a pointer to a vBaseWindow, which includes all V windows and dialogs, or a pointer to the vApp object. You will usually pass the this to the constructor.
int AskYN(const char* prompt)
You provide a prompt for the user. The user will then press the Yes, No, or Cancel buttons. AskYN returns a 1 if the user selected Yes, a 0 if they selected No, and a -1 if they selected Cancel.
Example
The following is a simple example of using vYNReplyDialog.
#include <v/vynreply.h>
...
vYNReplyDialog ynd(this); // instantiate a notice
int ans = ynd.AskYN("Exit. Are you sure?);
if (ans == 1)
exit(0);
