Hi,
I have a MM+ Explore 100, running v5.05.03, and I am using the "GUI Number Box" graphic to enter a calibration weight variable, but can't get the "ghost text" feature to work.

The correct text appears in the box when touched, set with :-
CTRLVAL(#Num_box%)="##ghost txt"

but then it doesn't disappear when a key is touched, but stays visible and appears to become part of the entry, scrolling left as new digits are added.

Does this feature work - or do I need to do something more?

With best regards, Paul.

Nothing so constant as change.

It's a MMBasic platform that you haven't got, Stan. :)

It does work Paul - I remember testing it in detail. The ghost text should vanish when the first character is entered.

At this time I am away from my workbench so I cannot run a test. If you can't get it working in a couple of days please post again and that will prompt ne to setup a test rig and try to verify (and fix) the issue.

Hi Geoff,
Thanks for your reply. I'll try some code in a dedicated program, but at the moment I am puzzled.
With best regards, Paul.

Hi,
I am trying to present the Number Box graphic as a Button, so that there is a consistent use of only Buttons throughout the project to trigger actions.

A Button is placed exactly over the Number Box graphic, with the Button drawn after the Number Box, but the #Ref number for the Number Box is lower than the Button, so gets priority when this area of the screen is touched. Both graphics are Enabled.

The Number Box should then appear as a Button graphic.

I'm still playing with ideas at the moment, but lose the Ghost Text if I REDRAW the Number Box to remove the Button image, while the number entry is in progress.

I'll post some code later to demonstrate what I can't quite achieve - if you follow me!

All suggestion welcome as to how to achieve this contortion of MMBasic!

With best regards, Paul.

p.s. To Geoff.
=============
YES - Ghost Text definitely DOES work ordinarily - please don't worry about checking!
My apologies.
It's what I am trying to do that loses it - REDRAW'ing the control when the number-pad is on the screen.
