New to Xbase but have an app that has a couple of fields (lets say
customers) and tab pages (say invoices) when I start the tab pages are blank
until I select one of the tab pages and its populated with the info I want,
no if I skip to the next customer the old data invoices remain visible in
the previous tab page.  I want to have the tabpage clear when navigating to
a new customer but how do I clear what is displayed on the tabpage in
clipper would do @10,10 to 20,60 clear, is there some equal in Xbase.

Thanks

Either destroy or hide the GUI controls. The easiest way is to have an
array(s) that contains reference to the controls on the page in question.

ie every time you create a control add it to the aPageControl array.

oCtrl := XbpSLE():New()
oCtrl:Create()

AADD(aPageControl,oCtrl)

etc

when you are done and want to clear these controls

AEVAL(aPageControl, {|a| a:destroy()})
aPageControl := {}

will zap all the controls for that page.

if hiding
AEVAL(aPageControl, {|a| a:Hide()})

to reshow them
AEVAL(aPageControl, {|a| a:Show()})

Remember that unlike in DOS you are not simply painting something on the
screen you a putting an object on the screen. To get rid of it you must
destroy the object.

You might want to look at my SLEPic class to get more Clipper like
navigation and pictures in a XBpSLE compatible class

hi,

> ... if I skip to the next customer the old data invoices remain visible in
> the previous tab page.  I want to have the tabpage clear ...

why not :refresh() and show next customer ?
like in Jim exsample use :

AEVAL(aPageControl, {|a| a:Setdata(), a:show()})
