Widget Events Returned by Droplist Widgets
Pressing the mouse button while the mouse cursor is over an
element of a droplist widget causes the widget to change the label
on the droplist 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_DROPLIST_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:
DROPLIST_NUMBER: the number of elements currently
contained in the specified droplist widget.
DROPLIST_SELECT: the zero-based number of the
currently-selected element (i.e., the currently-displayed
element) in the specified droplist widget.
DYNAMIC_RESIZE: a True value (1) if the widget specified
by Widget_ID is a button, droplist, 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
permet de modifier l''etat de la droplist comme on peut le faire
pour WIDGET_DROPLIST Impose peut etre:
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_DROPLIST_PM widget (see the documentation
for the DYNAMIC_RESIZE keyword to WIDGET_DROPLIST
procedure for more information about dynamic widget
resizing).
DROPLIST_SELECT:Set this keyword to return the zero-based
number of the currently-selected element (i.e., the
currently-displayed element) in the specified droplist
widget.
VALUE: The contents of the list widget (string or string
array)
