Title: Scroll in Label
Post by: Zittergie on July 16, 2014, 10:52:05 pm

Hi,

is it possible to scroll up and down in a label.  The label has a fixed height and wordwrap is TRUE.
See the picture.  I would like to add a possibility to scroll the lyrics up and down (or a scrollbar) when the lyrics are bigger than the label.

Greetz,
Bart

Hi,

you can take a look at Lazarus -> Help -> About Lazarus, tab Contributors, and search the sources.

Or, if you don't want the user can scroll it, you could put it into a TPanel and scroll it programatically.

Forgot to mention, the lyric should have to stay transparent.
Scrollbox works, but I don't find a way to make the box transparent. Setting the color to 'none' makes the box White.

I know this thread is old, but maybe someone else needs this in the future too ...  :)
The text isn't transparent, but the background is ...

This scrolls very nice:
// BrushStyle:= bsClear (Transparent Background)
