Xailer & OZ Software

Hi,
I want to create a list of say 'Clubs' or 'Interests' that a person has and
allow them to 'tick' the 'Cluds or 'Interests' they have. The List of
'Clubs' or 'Interests' are maintained in a .dbf.
I have loaded an array browse from the dbf with the necessary columns and an
extra column for the 'ticks' ... see image.
I have made column 3 editable ..... so I can type say an X in the column
where necessary.
My questions are ....
1. Is there a Xailer control that would do this for me more easily? Maybe
a Column edit type of 'CheckBox'?
2. If I do use an arraybrowse like here ...... I want to set the X just
with the Spacebar ... I can add code to the oGridEdit:onChar event and
detect nKey=32 but dont know how to return an X to the screen.
3. If I do use an arraybrowse like here ...... I want to minimise keypresses
and EXIT my get using the UP/DOWN keys but I think these are captured at the
browse level and I cannot find an event to capture them and force the
oGridEdit to exit.
Any suggestions would be appreciated.
Regards, Chris

Hi,
I have solved my own Questio 2 ... Setting to X ... I need to set the
oGridEdit:Value to X ... simple.
Question 3, detecting UP/DOWN arrows and exiting the oGridEdit ... still
struggling on that.

Hi,
1) In case is not a row edition (check the method IsMultipleEdit) I suggest
you use two images for checked & unchecked and change its value on the
TBrwColumn:OnEdit event and returning false. In case is a row edition I
suggest you use a listbox with the values 'Yes' & 'No'
2) It seems you already got this working
3) The keys are first processed by the TBrwColumn:oGridEdit and you can trap
them with oGridEdit:KeyDown() if you want. BTW the Key down and key up are
stopped on the control to avoid the propagation to its container browse.
You may overload TGridEdit to receive those events:
CLASS TGridEdit FROM XGridEdit
METHOD WMKeyDown( nKey, nFlags, hWnd )
END CLASS
METHOD WMKeyDown( nKey, nFlags, hWnd ) CLASS TGridEdit
IF nKey == VK_UP .OR. nKey == VK_DOWN
::OnKeyDown( nKey, nFlags )
ENDIF
RETURN Super:WMKeyDown( nKey, nFlags, hWnd )

Chris,
you can do it with a Treeview control.
Drop a TTreeview on a form and set lLinesAtRoot to .F. and lCheckBoxes to
.F., add the items and you are done.
To check what items are selected just loop the :aItems property:
AEval( ::oTreeview:aItems, {|oItem| IIf( oItem:lChecked, ...

Chris,
> lCheckBoxes to .F., add the items and you are done.
ups, I meant .T.

Ignacio,
Thanks for your time in explaining some of the inner workings.
The overloading of Methods is something I need to remember particularly for
key handling in special cases.
I will see how I get on.
Thanks
Chris

Jose,
Thanks for guiding me towards a TTreeview with check boxes.
I am experimenting with that and it is almost perfect.
Thanks
