Some weird scaling issues. See attached image.

Hint size is corrected by including a custom manifest, setting DPI-aware.

But then some other elements, but not all, are scaled that shouldn’t be scaled.

P.S. Using sAlphahints, rather than native hints, fixes the hint size issue. So best not to use the manifest.

Hello, Kevin!
Which RAD Studio version do you use?

[kevin]

I’m using XE3.

[Support]

Thanks for the info. XE3 have not good support of scaling, so, maybe your solution is the best for this cause.

> XE3 have not good support of scaling

Yes, however I’m loathe to spend several thousand dollars on the latest version of Delphi.

For non-alphacontrols apps, the DPI-aware manifest option works fine for scaling. One simply sets form scaling to true, and be sure to use truetype fonts. Some manual adjustments still need to be made to listbox itemheights and grid rowheights.

But alphacontrols works fine too, using sAlphahints rather than native hints.

Is there a way to change the background color of alphahints to white – or whatever color the system is using – rather than yellow?

[Support]

Yes, it’s possible, I will prepare an example code soon.

Try to use this code in the TsSkinManager.OnActivate and OnAfterChange events:

begin
  if sSkinManager1.SkinCommonInfo.Sections[ssHint] >= 0 then
    with sSkinManager1.gd[sSkinManager1.SkinCommonInfo.Sections[ssHint]] do begin
      BorderIndex := -1; // Do not use predefined image if exists
      BorderWidth := 1;
      BorderRadius := 2;
      Props[0].Color := clYellow;
      Props[0].BorderColor := clBlue;
      Props[0].FontColor.Color := clRed;
    end;
end;

required:
uses sStyleSimply;

Sadly, this doesn’t work when I tried it. This is the code I used to test it:

unit Unit1;

interface

uses
  Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
  Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, acAlphaHints, sSkinManager;

type
  TForm1 = class(TForm)
    Button1: TButton;
    sSkinManager1: TsSkinManager;
    sAlphaHints1: TsAlphaHints;
    procedure sSkinManager1Activate(Sender: TObject);
    procedure sSkinManager1AfterChange(Sender: TObject);
  private
    { Private declarations }
    procedure SetHintColor(HintColor : TColor);
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

uses sStyleSimply;

const
  // NewHintColor = clWhite;
  NewHintColor = clGreen;

procedure TForm1.SetHintColor(HintColor : TColor);
begin
  if sSkinManager1.SkinCommonInfo.Sections[ssHint] >= 0 then
    with sSkinManager1.gd[sSkinManager1.SkinCommonInfo.Sections[ssHint]] do begin
      BorderIndex := -1; // Do not use predefined image if exists
      BorderWidth := 1;
      BorderRadius := 2;
      Props[0].Color := HintColor;
      Props[0].BorderColor := clBlue;
      Props[0].FontColor.Color := clRed;
    end;
end;

procedure TForm1.sSkinManager1Activate(Sender: TObject);
begin
  SetHintColor(NewHintColor);
end;

procedure TForm1.sSkinManager1AfterChange(Sender: TObject);
begin
  SetHintColor(NewHintColor);
end;

end.

Update: setting sAlphaHints1.UseSkinData to true will display the modified color, but only the first time the hint is shown. Thereafter the hint is completely transparent, with no visible text.

[kevin]

I ended up solving my scaling issues, which were complex.

The problem isn’t with Alpha controls / skin manager.

With XE3 I have to manually include a manifest file which specifies DPI-Aware. This takes care of the hint scaling.

The other scaling issues were caused by other issues.

For reference, in case others have issues with font size, always check that the form scaiing is set to false, and also check the forms “ParentFont” setting, and whether there are any other manual font size settings in the code.

Hello, Kevin! Thank you for information.
