HOW CAN I DISABLE ZOOM IN DATAWINDOW'S PB8

[zakkar]

Hello,
It's not much of a problem but sometimes it becomes annoying.In pb8 when i have focus in a datawindow control if i press ctrl key and the rollover button of the mouse then the datawindow control starts to maximize or minimize .Like if i have called the zoom command.Probably it's default of the powerbuilder 8.How can i disable it?.It does this in all of my screens so i assume that it is a general property of Pb.Any suggestions?
Thank you in advance

Hi,

You need to trap the mousescroll event on the datawindow. I do not know if PB8 has a defined event i.e. pbm_mousescrolldown (or whatever), which you could add to the datawindow as a user event. I had success in PB6.5 using the

other

event (it's the one which all non-PB messages [i.e. windows] are sent to), and trapping on the

WPARAM

event argument. Return 1 to stop any further processing of a message, and 0 to allow continued processing. The windows.h (or one of the later ms header files) should contain the definition of the messages you'll need. If you want to output the values sent to the

other

event, use a multilineedit control and code like this in the datawindow's

other

event:

mle_1.text += (String(wparam) + " :: " + String(lparam) + "~r~n")
mle_1.SelectText(Len(mle_1.text),0)

return 0

Do not use a MessageBox as things will get messy.

Cheers.
