---|
| 8 | ; dispose de 2 bouttons + et - pour deplacer le widget de +/- 1. |
---|
| 9 | ; |
---|
| 10 | ; CATEGORY: compound widget (aide a l''ecriture des widgets) |
---|
| 11 | ; |
---|
| 12 | ; CALLING SEQUENCE: id=cw_combobox_pm(parent) |
---|
| 13 | ; |
---|
| 14 | ; INPUTS: |
---|
| 15 | ; Parent: The widget ID of the parent widget. |
---|
| 16 | ; |
---|
| 17 | ; KEYWORD PARAMETERS:tous ceux de WIDGET_COMBOBOX |
---|
| 18 | ; |
---|
| 19 | ; OUTPUTS: |
---|
| 20 | ; The returned value of this function is the widget ID of the |
---|
| 21 | ; newly-created animation widget. |
---|
| 22 | ; |
---|
| 23 | ; COMMON BLOCKS: none |
---|
| 24 | ; |
---|
| 25 | ; SIDE EFFECTS: |
---|
| 26 | ; |
---|
| 27 | ; Widget Events Returned by Combobox Widgets |
---|
| 28 | ; |
---|
| 29 | ; Pressing the mouse button while the mouse cursor is over an |
---|
| 30 | ; element of a combobox widget causes the widget to change the label |
---|
| 31 | ; on the combobox button and to generate an event. The appearance of |
---|
| 32 | ; any previously selected element is restored to normal at the same |
---|
| 33 | ; time. The event structure returned by the WIDGET_EVENT function is |
---|
| 34 | ; defined by the following statement: |
---|
| 35 | ; |
---|
| 36 | ; { CW_COMBOBOX_PM, ID:0L, TOP:0L, HANDLER:0L, INDEX:0L, OUT:0 } |
---|
| 37 | ; |
---|
| 38 | ; The first three fields are the standard fields found in every |
---|
| 39 | ; widget event. |
---|
| 40 | ; INDEX returns the index of the selected item. This can be used to |
---|
| 41 | ; index the array of names originally used to set the widget''s |
---|
| 42 | ; value |
---|
| 43 | ; OUT:c''est un entier qui peut prendre 3 valeurs: |
---|
| 44 | ; 1 : si on appuie sur + alors que l''index est deja aux max. rq: |
---|
| 45 | ; ds ce cas l''index reste au max |
---|
| 46 | ; -1: si on appuie sur - alors que l''index est deja aux min. rq: |
---|
| 47 | ; ds ce cas l''index reste au min |
---|
| 48 | ; 0 : ds les autres cas! |
---|
| 49 | ; |
---|
| 50 | ; Keywords to WIDGET_CONTROL |
---|
| 51 | ; |
---|
| 52 | ; A number of keywords to the WIDGET_CONTROL procedure affect the |
---|
| 53 | ; behavior of cw_slider_pm widget: GET_VALUE and SET_VALUE. |
---|
| 54 | ; 1) GET_VALUE |
---|
| 55 | ; widget_control,wid_id,get_value=resultat |
---|
| 56 | ; retourne ds la variable resultat une structure de 3 elements dont |
---|
| 57 | ; les noms sont inspires des mots cles que l''on peut passer a |
---|
| 58 | ; widget_control qd on utilise WIDGET_COMBOBOX: |
---|
| 59 | ; COMBOBOX_NUMBER: the number of elements currently |
---|
| 60 | ; contained in the specified combobox widget. |

| 61 | ; COMBOBOX_SELECT: the zero-based number of the |
---|
| 62 | ; currently-selected element (i.e., the currently-displayed |
---|
| 63 | ; element) in the specified combobox widget. |
---|
| 64 | ; DYNAMIC_RESIZE: a True value (1) if the widget specified |
---|
| 65 | ; by Widget_ID is a button, combobox, or label widget that |
---|
| 66 | ; has had its DYNAMIC_RESIZE attribute set. Otherwise, |
---|
| 67 | ; False (0) is returned. |
