TAlphacolor 色に関するメモ


  function valueToColor(aValue: double): TAlphaColor;
  var
    tmpSingle: Single;
    tmpAlphaColor: TAlphaColor;
  begin
    // 割合を0.15 なら1とするように切り上げる
    tmpSingle := aValue * (1/0.15);
    if tmpSingle > 1 then tmpSingle := 1;
    // 最大値 160(青) 最小値 0(赤)に補正
    tmpSingle := tmpSingle * 220 / 360;
    tmpAlphaColor := HSLtoRGB(tmpSingle, 0.75,0.5);

    tmpAlphaColorRec.Color := tmpAlphaColor;

    result := MakeColor(tmpAlphaColorRec.R,
                        tmpAlphaColorRec.G,
                        tmpAlphaColorRec.B,
                        $80);

TcomboBox コンボボックス TCombobox コンボボックスのまとめ

ボックスアイテムのフォントサイズを設定

  for i := 0 to frmConfig.cmbDesignFontName.Count -1 do
  begin
    frmConfig.cmbDesignFontName.ListItems[i].StyledSettings := [];
    frmConfig.cmbDesignFontName.ListItems[i].Font.Size := 11;
  end;

フォントと列挙


procedure TfrmMain.initFontCombo;
var
  tmpFileList: TstringList;
  i: Integer;
  DC:HDC;

  function EnumFamToLines(lplf: PLOGFONT; lpntm: PNEWTEXTMETRIC;
                            FontType: DWORD; Lines: LPARAM): Integer; stdcall;
  begin
    with lplf^ do
//      if    (lfCharSet = SHIFTJIS_CHARSET) and (lfPitchAndFamily and $0F = FIXED_PITCH) then
      // シフトJIS文字セット
      if    (lfCharSet = SHIFTJIS_CHARSET) then
        TStrings(Lines).Add(lplf.lfFaceName);
    Result := 1;
  end;

begin
  tmpFileList := TstringList.Create();
  DC := GetDC(0);
  tmpFileList.Clear;

  frmConfig.cmbDesignFontName.Items.Add(DEFAULT_DesignFontName);

  EnumFontFamilies(DC, nil, @EnumFamToLines, LongInt(tmpFileList));
  for i := 0 to tmpFileList.Count - 1 do
    if pos('@', tmpFileList[i]) = 0 then
      frmConfig.cmbDesignFontName.Items.Add(tmpFileList[i]);
  tmpFileList.Free;

  for i := 0 to frmConfig.cmbDesignFontName.Count -1 do
  begin
    frmConfig.cmbDesignFontName.ListItems[i].StyledSettings := [];
    frmConfig.cmbDesignFontName.ListItems[i].Font.Size := 11;
  end;

end;

OnChange のタイミング

iOS では clear で OnChange イベントが発生する
iOS では BeginUpdate、EndUpdate が無いとエラーが起こる可能性がある?

  frmMain.cbxValueStep.BeginUpdate;
  frmMain.cbxValueStep.Items.Clear;
  for i := 0 to TValueStep.count - 1 do
  begin
    tmpValueStep.serial := i;
    ListBoxItem      := TListBoxItem.Create(frmMain.cbxValueStep);
    ListBoxItem.Tag  := tmpValueStep.serial;
    ListBoxItem.Text :=tmpWatchPair.pipToPriceStr(tmpValueStep.pip);
    frmMain.cbxValueStep.AddObject(ListBoxItem);
  end;

  frmMain.cbxValueStep.EndUpdate;

LiveBinding 利用のための調査

注意点

・ A から B にリンクした場合、Bの初期値がAに渡される。(Aの初期値がBに渡されるわけではない。)?

・ LiveBinding デザイナでドラッグでリンクできない場合はウィザードを使えばリンクできる。

正確なタイマーを無理やり作る

Firemonkey TTimer はざっくりしすぎているので、TStopWatch を使って正確な時間を測る。
これでずいぶん正確になった。

Firemonkey の TCheckbox のイベントについて

onChange イベントは変更後の IsChecked を正しく持っている。
ただし、コードによって変更された場合もこのイベントは起こってしまう。

onClick イベントは、変更される前に呼び出されてしまう。

で、インターバル50msくらいのタイマーを置いて、こんな感じ。

procedure TfrmMain.tmrForCheckBoxTimer(Sender: TObject);
begin
  DispSearchResult();
  tmrForCheckBox.Enabled := False;
end;

procedure TfrmMain.chkIsOnlySeionClick(Sender: TObject);
begin
  tmrForCheckBox.Enabled := True;
end;

もっといい方法が絶対あるはずだけど、とりあえずこれでOK。

15日目 property に代入できない件

config.HSTimeStep.Enum := ts1Hour;

に代入しようとして、「代入できない左辺値です」的なエラーが出るとき、
プロパティーの定義をチェックしてみると、

ダメパターン
property Enum: TTimeStepEnum   read FEnum        write FEnum;

OKパターン
property Enum: TTimeStepEnum   read FEnum        write setEnum;
procedure TTimeStep.setEnum(const Value: TTimeStepEnum);
begin
FEnum := Value;
end;

だった。
