Hi,
I can not seem to get my WIN_CONSUME_EVENTS to direct LOC_DRAG and/or
WIN_MOUSE_BUTTONS events to me! LOC_MOVE seems to work fine, but
I don't get ANY events with any button down. Can anyone help? I
have included my xv_create() for the canvas below. Is there something
I need to enable on the Base Frame? If so what?

That's because you're asking for events on canvas, not the paint window. Change you're code to include something like the following: ... CANVAS_PAINTWINDOW_ATTRS, WIN_CONSUME_EVENTS, WIN_MOUSE_BUTTONS, LOC_DRAG, LOC_MOVE, LOC_WINEXIT, NULL, WIN_EVENT_PROC, CB_Canvas, NULL, ... >FracCanvas = (Canvas) xv_create(BaseFrame,CANVAS, > CANVAS_AUTO_SHRINK ,FALSE, > CANVAS_AUTO_EXPAND ,FALSE, > CANVAS_RETAINED ,FALSE, > CANVAS_HEIGHT ,XFP_IMAGE_HEIGHT, > CANVAS_WIDTH ,XFP_IMAGE_WIDTH, > CANVAS_AUTO_CLEAR ,FALSE, > CANVAS_X_PAINT_WINDOW,TRUE, > CANVAS_REPAINT_PROC ,CB_Repaint, > WIN_EVENT_PROC ,CB_Canvas, > WIN_CONSUME_EVENTS ,LOC_MOVE, > LOC_WINEXIT, >/* LOC_DRAG or WIN_MOUSE_BUTTONS here does NOT help !!??!! */ > NULL, > XV_HEIGHT ,XFP_IMAGE_HEIGHT+2, > XV_WIDTH ,XFP_IMAGE_WIDTH+2, > NULL); -brian brianw@Eng.Sun.Com
