TMaskEdit mask question

[brody]

Hi:
I have a edit mask with this pattern.  #999.99;0;_    (and several other variations. )

But, when I enter data, such as -53.15   the cursor JUMPS to the 10's column when I press the '.', leaving me with a field of -53_.15    which is NOT what I'm looking for.   I'm wanting -53.15.

What am I missing in the concept of the editmask?  Or do I still have to validate the output of the mask edit?

Thanks,
Brody

IIRC then pressing '.' will just do that: jump to the first position after the dot.
AFAIK that is Delphi compatible.

you can correct that in the OnChange event and OnKeypress etc..

 But its not really worth it I would say?

 Try the TFloatSpinEdit control instead. That have much better formatting .
Its in the Misc tab.

Interesting, while exploring using the OnChange event of the TMaskEdit to
fix the gapping issue I find that "CaretPos" always reports 0,0 only in the
OnChange event but works in other events.

 Then I checked TEdit since they are based from the same control and the
OnChange event there does report the CaretPos.

 TMaskEdit.OnChange(....);
  Begin
     MaskEdit.CaretPos.X  always reports 0 while editing !


But this works in TEDIT.OnChange..

 lazarus 1.8 64 bit, most likely in the 32 bit too!

Try using selstart.

Why would I do that? The idea is to find the caretpos which reports where the
user is at the time during editing..

 Using selstart would imply I knew where things are?

Code: Pascal  [Select][+][-]

1. [/ GetCaretPos(P);
2.   IntPtr(P):= SendMessage(MaskEdit1.Handle,EM_CHARFROMPOS,0,MakeLParam(P.X,P.Y));      code]
3.  
4. That seems to work..
5.

You lost me there.

Is CaretPos accurate outside OnChange?

Yes, in other events of MaskEdit, like Keyboards, mouse move etc, the CaretPos
reports true.

 In the Onchange revent, it always reports 0.

 By using the SendMessage approach as I outlined before, it is able to get
the actual character position using the current caret position in the control.
 
 I have reported this, I think a modification to the code is going to be done.
 
 Without this for it makes it hard to customize the MAskedit during editing
in a cross platform arena.
