GetObjectAtPointer

Description

Reports the control within the DataWindow object and row number under the pointer. Controls include columns, labels, and other graphic controls, such as lines and pictures.

Applies to

DataWindow type

Method applies to

PowerBuilder

DataWindow control


Syntax

PowerBuilder

string dwcontrol.GetObjectAtPointer ( )

Argument

Description

dwcontrol

A reference to a DataWindow control


Return value

Returns the string whose value is the name of the control under the pointer, followed by a tab character and the row number. Returns the empty string ("") if an error occurs.

If dwcontrol is null, the method returns null.

Usage

If the object doesn't have a name, neither a name nor a row is reported. Since PowerBuilder 7, the painter gives names to all controls. In earlier versions, only columns and column labels got default names in the DataWindow painter and you could name other controls yourself.

You can parse the return value by searching for the tab character (ASCII 09). In PowerBuilder, search for ~t. For an example that parses a string that includes a tab, see GetValue.

For information on the rows associated with bands and therefore with controls in those bands, see GetBandAtPointer.

Examples

These statements obtain the name of the control under the pointer in the DataWindow dw_emp:

String dwobjectname
dwobjectname = dw_emp.GetObjectAtPointer()

Some possible return values are:

Return value

Meaning

salary~t23

The control named salary in row 23.

salary_h~t15

The control named salary_h, which is in the header. Row 15 is the first visible row below the header.
