Does anybody know where the routine resides that actually does the splitting into lines of TLabel.Caption (if WordWrap is true)? I don't like it's behaviour and want to change (overwrite) it.

Currently, long lines are not wrapped when no spaces exist. I am wondering why this is the case because the reason for wrap is, that the whole text should be visible all the time. And that's not the case now.

Probably done by the widgetset.

In Object Inspector:
AutoSize = False
WordWrap = True

With the mouse, expand more the Label component to the desired point.

???
I am not able to change the size of the label at runtime with the mouse. And even if this would work I would not like it as I want it to be done *automatically* (as it does when spaces exist).

I fear that it's like that.
Too bad that programmers have less and less
of their programs under their control.

See

function TCustomLabel.CalcFittingFontHeight(const TheText: string;
   MaxWidth, MaxHeight: Integer;
   var FontHeight, NeededWidth, NeededHeight: integer): Boolean;

A flag is given to DrawText

You can look up DrawText in each widgetset, it may exist with and without themes...
Best to hit it in the debugger, and see where it goes.

What exactly do you want to change?

IMHO it works very well, even with auto-sizing, BUT you need to anchor left and right to other controls

I already stepped through everything with the debugger but couldn't see how and where the text is splitted into lines.

If the text contains no spaces it is not want to change this and split the text in all situations (independend from the content of the text).

Possible tat on some OS, it si done by the OS itself.

IIRC on gtk, there is something in the WS. But others I do not know.

Ah. No Idea.

If you need it cross platform then you have to implement your own TLabel descendant and do the drawing and size calculation yourself. Or patch TLabel. It's open source.

Hence the reason I have always been pro about fully custom implemented toolkits. The developer then has FULL control over the look, feel and behaviour of the toolkit.
