XmActivateWMProtocol — A VendorShell convenience interface that activates a protocol Synopsis #include <Xm/Protocols.h> void XmActivateWMProtocol( Widget shell, Atom protocol); Description XmActivateWMProtocol is a convenience interface. It calls XmActivateProtocol with the property value set to the atom returned by interning WM_PROTOCOLS. shell Specifies the widget with which the protocol property is associated protocol Specifies the protocol…
XmActivateProtocol — A VendorShell function that activates a protocol Synopsis #include <Xm/Protocols.h> void XmActivateProtocol( Widget shell, Atom property, Atom protocol); Description XmActivateProtocol activates a protocol. It updates the handlers and the property if the shell is realized. It is sometimes useful to allow a protocol’s state information (callback lists, and so on) to persist, even…
