Re: bindevents(): What Use?

In my custom grid class I have this code in a custom Setup method:

LOCAL loColumn As Column, loControl As Control, lnHeight As Integer, lnRows

As Integer, ;

lnScrollHeight As Integer

WITH THIS

.ReadOnly = .T.

FOR EACH loColumn IN .Columns

IF loColumn.FontName # .FontName

loColumn.FontName = .FontName

ENDIF

BINDEVENT(loColumn.Header1, "RightClick", THIS, "HandleRightClick")

FOR EACH loControl IN loColumn.Controls

IF loControl.FontName # loColumn.FontName

loControl.FontName = loColumn.FontName

ENDIF

*!* Handle a double click for any control in the grid

*!* Processed by the grid double click

IF PEMSTATUS(loControl, "DblClick", 5)

BINDEVENT(loControl, "DblClick", THIS, "DblClick")

ENDIF

ENDFOR

ENDFOR

IF .IntegralHeight

lnScrollHeight = IIF(BITAND(.ScrollBars,1) = 1, SYSMETRIC(8), 0)

lnHeight = .Height - .HeaderHeight - lnScrollHeight

lnRows = ROUND(lnHeight/.RowHeight,0)

lnHeight = .RowHeight*lnRows + .HeaderHeight + lnScrollHeight

.Height = lnHeight + 1

ENDIF

ENDWITH

The behaviour for RightClick and DblClick is handled at the form level. One

use is when a user double clicks a row in the grid, a value (usually a

table primary key), is sent to another form.
