xtcallbacka
XtCallbackNone() XtCallbackNone()
Name
XtCallbackNone - callback function to pop up a widget.
Synopsis
void XtCallbackNone(w, client_data, call_data)
Widget w;
XtPointer client_data;
XtPointer call_data;
Inputs
w Specifies the widget.
client_data
Specifies the popup shell.
call_data Specifies the callback data, which is not used by this procedure.
Description
XtCallbackNone() calls XtPopup() on the widget passed in the client_data argument with grab_mode set to XtGrabNone. Then it calls XtSet-
Sensitive() on w to make that widget insensitive.
XtCallbackNone() is a convenience procedure designed to be registered on a widget's callback list (which is why it has a third, unused
argument). The widget to be popped up should be registered as client_data for the callback. The reason that this callback makes its
invoking widget insensitive is so that the user cannot request to popup the shell again while it is already up.
Usage
To popup a shell with an exclusive grab or with no grab at all, you can use XtCallbackExclusive() or XtCallbackNone(). To popdown a shell
from a callback, use XtCallbackPopdown().
Note that this function does not attempt to place the popup shell at any particular location, and for that reason may not be appropriate in
many circumstances.
It is also possible to pop up a shell with the XtMenuPopup action.
Example
To arrange for the shell pshell to be popped up when the user clicks on the button widget button, you would use code like the following:
XtAddCallback(button,XtNcallback,XtCallbackNone,pshell);
A companion example is presented on the XtCallbackPopdown() reference page.
