Context Events in Draw Widgets

Context Events in Draw Widgets

The WIDGET_DRAW function does not have a CONTEXT_EVENTS keyword to specify that context menu events be generated when the user clicks the right mouse button over a drawable area. Instead, the event structure generated by draw widgets when the BUTTON_EVENTS keyword is set includes the PRESS and RELEASE fields, both of which contain information regarding which mouse button was pressed.
