    Ambiguity between Idtcpclient::TidTCPClient and Uidtcpclient:TidTCPClient in RAD 12.1

    in General

    Posted

    Hi Farshad / Sherzod
    I have upgraded to RAD 12.1 and UniGUI Professional V 1.95.0.1583

    I have successfully installed UniGUI v1583, but when I compile my C++ project (previously compiled with RAD 10.4), I get an error:

    Ambiguity between Idtcpclient::TidTCPClient and Uidtcpclient:TidTCPClient

    I have a RAD IdTCPClient component on my UniGUi form and this seems to be clashing with the TCPClient used by UniGui framework.
    How do I resolve this ambiguity?

    Hi Farshad

    Thank you for your adivce, I resolved that problem.

    However I have one error left: Ambiguity between Idtcpclient::TidTCPClient and Uidtcpclient:TidTCPClient

    I will create a new thread for that error.

    Fatal error: Unable to open file UniGui27Chart.bpi

    Why would the compiler be looking for UniGui27Chart.bpi?
    It should anyway be  UniGui29Chart.bpi

    Hi Sherzod

    I ‘m very happy with uniGUI and would like to renew my uniGUI Complete - Professional Edition license.

    On your web-site it says that the price for renewal is around 60% of original price, but I cannot find a link where to renew?

    UniCanvas is black the first time being used

    I'm using a UniCanvas but the very first time I draw something on it, its starts off being black even though the Brush Color is clWhite?

    The following code always show a black Canvas the very first time its used. When the code is executed a second time thereafter the background is white as it should be.

    UniCanvas1.Clear;
    UniCanvas1.Brush.Color:=clWhite;     
    UniCanvas1.MoveTo(X1, Y1);
    UniCanvas1.LineTo(X2, Y2);

     

    If I just execute the first two lines once:

    UniCanvas1.Clear;
    UniCanvas1.Brush.Color:=clWhite;     

    I end up with a black canvas.

    The UniCanvas sits on a UniPanel.

    I'm using UniGUI Complete Professional V1.90.0.1560 

     

    Another question: Is there any way to display Text on a UniCanvas?

     

    UniCanvas SaveToFile creates empty file

    I just did a test to draw something via

    UniCanvas.BitmapCanvas.Rectangle(10, 10, 100, 100);

    and then the UniCanvas1.SaveToFile(fName,tiBMP);

    work correctly, so that has been resolved.

    But I still want to save a portion of the screen (whatever components are on the Canvas, e.g. UniPanel with UniChart etc.) to a file or stream.

    Can this be done using a UniCanvas or can one only draw to the UniCanvas?

    I'm not drawing anything on the UniCanvas.
    I have inserted a UniChart on the UniCanvas.
    I am using UniCanvas1.SubmitData but
    maybe the UniCanvas has not received the data of the UniChart?

    So what setting must I use on the UniCanvas to make sure the UniCanvas has received the data of all components/controls on the UniCanvas?

    Or how does one transfer/save the image of components on the UniCanvas, or is this not possible?

    procedure TMainForm.UniButton1Click(Sender: TObject);
begin
  UniChart1.SaveImage;
end;

procedure TMainForm.UniChart1ChartImage(Sender: TUniCustomChart; Image: TGraphic);
var
  fName : string;
begin
  fName := UniServerModule.LocalCachePath + 'Chart.png';
  Image.SaveToFile(fName);
  UniSession.SendFile(fName);
end;

    When using Image.SaveToFile(FileName), how does one set the file type?

    For example, if I want to use a jpg, how do I set JPG, or does UniGUI automatically look at the extension of the FileName?

    So when one select, Print to PDF via the Delphi PrintDialog (see below), where is the PDF file saved?

    Or rather, how can I set the folder where the PDF is saved?
