Thank you Cristian! That did the trick.

Clever! 👏You must be very proud of yourself.

I try to receive hex data from serial port using AsyncPro. However, 0x80 returns 0x20AC. How to fix this?

I have an android app for which I would like two functions for one button.
The button would be an image that changes according to the event.
What would be the best way to do such a function?

here works, at least!

 

It works this way, but if you try to enlarge it, it doesn't work

I found one problem. Changing background visible -> false it is impossible to change grid size and position at runtime.

Thank you very much @programmerdelphi2k!  It is easy when you know what to do.

Is it somehow possible to change the background color and remove borders of the (string)grid in FMX?

I would like to align the data in a 4 x 10 grid but only keep the text visible and hide background and borders.

Hi,

Is there a way to prevent drawing outside the canvas?
If, for example, I have a rectangular shape on which I draw an ellipse and I want to limit the drawing to the area of the shape.

procedure TForm1.shapePaint(Sender: TObject; Canvas: TCanvas;
  const ARect: TRectF);
  var
  x,y :integer;
  circle : TRectF;
begin

    x:=round(shape.Width/2);
    y:=round(shape.Width/2);

    circle:=TRectF.Create(x-190,y-190,x+100,y+100);
    shape.Canvas.Stroke.Color:=TAlphaColors.Black;
    shape.Canvas.DrawEllipse(circle,50);
end;

Now part of it is also drawn outside the shape.

Thank you Uwe. Community edition is 10.4 and in this version you can get only code in a second edit window.

Hi,

I haven't used Delphi since version 6 but I thought now to try it again after a long break. So I downloaded community edition but noticed that floating form designer has disappeared.

I remember it was easy to design a gui in the past but now it is really difficult.

Is there any way to get a form designer full screen size?
