Why not...

add NumberOnly property to TLabeledEdit like TEdit?

Or, is it difficult to make TDBLabeledEdit, or TRTTILabeledEdit?

AFAIK TLabeledEdit is there mostly for Delphi VCL compatibility.
It works poorly with the LCL's anchor system. Better use a separate TLabel and anchor it with a desired type of edit control.
Mostly Lazarus trunk and FPC 3.2 on Manjaro Linux 64-bit.

Since this component inherits from TCustomEdit, it already has a NumbersOnly property.
I published it in commit 76182b6c and put it up for merging to fixes_3 branch.

However, NumbersOnly is not very useful. You cannot even enter neither a '-' for negative values nor a decimalseparator for floating point numbers. Simply: don't use it. Use a SpinEdit (FloatSpinEdit) or - if you don't like the spinner buttons - TSpinEditEx (TFloatSpinEditEx) with UpdownVisible=false.

Yet another thing we needed because Delphi has it (because Windows has it, but implemented it in a dumb-ass manor).
I'm sorry to say I ported it to Lazarus  :-[

Fortunately it is off by default.

BTW, do you know if this NumberOnly insanity happens only in Windows or also in other widgesets?

I would think on other WS it was implemented to behave as Windows does.
I would need to test though.
It's been a long time since this was discussed.
