Description
Occurs when the user releases a mouse button in a DataWindow control.
PowerBuilder event information
Event ID: pbm_dwnlbuttonup
MouseUp is not a standard PowerBuilder DataWindow event. To write a script for this event, you must first define a user event for the event ID pbm_dwnlbuttonup.
|
Argument |
Description |
|---|---|
|
xpos |
Integer by value. The distance of the pointer from the left side of the DataWindow's workspace. The distance is given in pixels. |
|
ypos |
Integer by value. The distance of the pointer from the top of the DataWindow's workspace. The distance is given in pixels. |
|
row |
Long by value. The number of the row under the pointer. If the pointer is not over a row, the value of the row argument is 0. For example, row is 0 when the user double-clicks outside the data area, in text or spaces between rows, or in the header, summary, or footer area. |
|
dwo |
DWObject by value. A reference to the control within the DataWindow that is under the pointer. |
Return Values
There are no special outcomes for this event. The only code is:
0 -- Continue processing
Usage
The dwo, Name, or DWObject argument provides easy access to the control the user clicks. You do not need to know the coordinates of elements within the DataWindow to program control-specific responses to the user's clicks. For example, you can prevent editing of a column and use the Clicked event to set data or properties for the column and row the user clicks.
PowerBuilder programming note
The xpos and ypos arguments provide the same values the functions PointerX and PointerY return when you call them for the DataWindow control.
