| _row | If the displayer of Browsertype generates the picture event, the parameter contains the row, above which the picture event was executed. Otherwise it contains invalid value. Optional parameter. |
| _col | If the displayer of Browsertype generates the picture event, the parameter contains the column, above which the picture event was executed. Otherwise it contains invalid value. Optional parameter. Warning: Number of column in parameter _col represents the sequential number based on how it is displayed, not how it is defined in the structure definition. |

parameter _row represents the line number (from 1) on the current page (i.e. it does not take into account any possible previous pages) parameter _col represents the column order (from left) as it is displayed (i.e. it does not represent the column index in the structure) |
Description
Example
Special picture event handler:
| Blok kódu | ||||
|---|---|---|---|---|
| ||||
; picture event handler: Double-clicking on the list box with reference variable List assigned ENTRY List_OnItemDoubleClick ; script actions END List_OnItemDoubleClick |
Global picture event handler:
| Blok kódu | ||||
|---|---|---|---|---|
| ||||
; picture events handler: Double-clicking on list box or
; displayer of Browser that has no special picture event handler defined
ENTRY OnItemDoubleClick(IN INT _refId)
; _refId - value of Reference local variable assigned to graphic object
IF _refId = _List THEN ; test that determines the graphic object the user clicked on
; script actions
ENDIF
END OnItemDoubleClick |
Note
If both the handlers are defined in picture script, the global handler never will be called for _refId=List, because a special handler is already defined.
For displayer of Browser type we recommend to use OnBrowserClick, which replaces and extends the functionality of OnItemDoubleClick.
