Event Mask Dialog

This dialog allows you to specify the types of events which an event handler may receive.

Simply turn on all the toggles in the dialog which represent the types of event which are of interest to you (for the current event procedure) then press the Apply button.

This will construct a mask, and return the value back into the Event Handler dialog.

Event Types are logically grouped for convenience, although you are referred to your X Toolkit documentation for the exact meaning of each of the available masks.

Note that it is not possible to select for certain types of event, since not all event types have a mask. These are the "Non-Maskable" events: as such, they do not appear in the Event Mask dialog, and you would need to turn on the Non Maskable toggle back in the Event Handler dialog should you wish to receive events of this type.

Again, you are referred to your X documentation to determine which events are non-maskable.
