Widget Events Returned by Combobox Widgets Pressing the mouse button while the mouse cursor is over an element of a combobox widget causes the widget to change the label on the combobox button and to generate an event. The appearance of any previously selected element is restored to normal at the same time. The event structure returned by the WIDGET_EVENT function is defined by the following statement: { CW_COMBOBOX_PM, ID:0L, TOP:0L, HANDLER:0L, INDEX:0L, OUT:0 } The first three fields are the standard fields found in every widget event. INDEX returns the index of the selected item. This can be used to index the array of names originally used to set the widget''s value OUT:It is an integer which can take 3 values: 1 : If we press + when the index is already at the max Comment: In this case, the index stay at the max -1: If we press - when the index is already at the min Comment: In this case, the index stay at the min 0 : In other cases Keywords to WIDGET_CONTROL A number of keywords to the WIDGET_CONTROL procedure affect the behavior of cw_slider_pm widget: GET_VALUE and SET_VALUE. 1) GET_VALUE widget_control,wid_id,get_value=resultat Send back, in the result variable, a structure of 3 elements whose names are inspired by keywords we can pass at widget_control when we use WIDGET_COMBOBOX: COMBOBOX_NUMBER: the number of elements currently contained in the specified combobox widget. COMBOBOX_SELECT: the zero-based number of the currently-selected element (i.e., the currently-displayed element) in the specified combobox widget. DYNAMIC_RESIZE: a True value (1) if the widget specified by Widget_ID is a button, combobox, or label widget that has had its DYNAMIC_RESIZE attribute set. Otherwise, False (0) is returned. 2) SET_VALUE widget_control,wid_id,set_value=impose Allows to modify the state of the combobox like we can do it for WIDGET_COMBOBOX. May impose: a) The contents of the list widget (string or string array) b) A structure which can have for elements (from 1 to 3): DYNAMIC_RESIZE:Set this keyword to activate (if set to 1) or deactivate (if set to 0) dynamic resizing of the specified CW_COMBOBOX_PM widget (see the documentation for the DYNAMIC_RESIZE keyword to WIDGET_COMBOBOX procedure for more information about dynamic widget resizing). COMBOBOX_SELECT:Set this keyword to return the zero-based number of the currently-selected element (i.e., the currently-displayed element) in the specified combobox widget. VALUE: The contents of the list widget (string or string array)
