Hello all,

I admit I haven't worked with GUI applications so far (total noob on
this topic). What I need is the following

- on a form I would like to have a single line textbox which is
scrollable
- the textual content will be provided by the program and must not be
editable by the user
- the text can become long (~1000 characters), therefore I would like
to have a scrollbar for the textbox

What is a reasonable control for the textbox (there seems to be no
direct fit in the available controls) and how do I associate the
scrollbar to it?

Hi
I'd use a TMemo and turn off 'WordWrap', turn on 'ssHorizontal' in
Scrollbars and finally turn on 'ReadOnly'.
Have a 'LookSee' in the attachment

Drop a TScrollbox on the form, turn off its VertScrollbar (Visible =
false). Drop a TLabel on the ScrollBox, move it to the top/left corner
of the scrollbox. Assign the text to the Label.Caption. Set the
ClientHeight of the scrollbar to the Height of the Label. Since the
Label has AutoSize=true by default it will be a single-line textbox.
And a Label cannot be edited.

Many thanks wp - I'll try that too. From your explanation it seems to
be even closer to my requirements.
