Summary0023369: Disabled TEdit and TDBEdit scroll text (when SelStart should be 0)
DescriptionHello, in a form I have:
-TEdit and TDBEdit with Enabled = True, to insert/modify data;
-TEdit and TDBEdit with Enabled = Fasle, to show description data;

I set the disabled TEdit/TDBEdit Text property on OnExit event, but also when I load the form, in case of data-aware components.

I've noted that on Linux/QT and Mac/Carbon, if the length of the text is greater als the width of the disabled TEdit/TDBEdit, the text is scrolled, and the user can see only the last part of the Text.

On Linux/GTK2 the user see the first part of the Text, and I think that would be the correct behaviour, because for description Fields is useful to see the first part of the Text and not the last.

On Linux/QT I can resolve if I use a set manually the SelStart property to 0.

On Mac/Carbon even if I set manually the SelStart property to 0 the problem remains.

The problem happens always, either on OnExit event, or on setting the description data when the form is loades.

Best regards,

I have the same issue.
I retest with lazarus-1.2RC1-0.tar.gz (2013-11-03)

An easy way for reproduce under linux qt is

Edit1.Text:='test (put many spaces here) ';

Setting text under Qt moves SelStart to the last char. What can I do here ? Have you checked value of SelStart when you set text ?
