I have recently switched to IDL7.1 from 7.0, and have a problem using WIDGET_SLIDER. Although DRAG is set for widget, drag events are not generated. The same code worked for 7.0. Has there been a change to the way the events are handled, and should I change the way they are used? The test program below runs as expected in 7.0, but not in 7.1 PRO testslider_event, ev common sliders, slider widget_control, slider, GET_VALUE=value print, value END PRO testslider common sliders, slider main = widget_base (xsize=200,ysize=100) slider = widget_slider (main,/drag) widget_control, main, /realize xmanager, 'testslider', main END
