Inno Setup - 在确定的页面中从右侧动画控制滚动

Question

我正在尝试使用此代码（使用 InnoCallback DLL 库）：

[Code]

var
  MainPanelAnimated: Boolean;
  AnimationTimer: LongWord;

procedure AnimationTimerProc(
  H: LongWord; Msg: LongWord; IdEvent: LongWord; Time: LongWord);
var
  L: Integer;
begin
  L := WizardForm.MainPanel.Left + ScaleX(5);
  if L > 0 then
  begin
    L := 0;
    KillTimer(0, AnimationTimer);
  end;
  WizardForm.MainPanel.Left := L;
end;

procedure CurPageChanged(CurPageID: Integer);
var
  HoverTimerCallback: LongWord;
begin
  if WizardForm.OuterNotebook.ActivePage = WizardForm.InnerPage then
  begin
    if not MainPanelAnimated then
    begin
      HoverTimerCallback := WrapTimerProc(@AnimationTimerProc, 4);
      AnimationTimer := SetTimer(0, 0, 5, HoverTimerCallback);
      WizardForm.MainPanel.Left := -WizardForm.MainPanel.Width;
      MainPanelAnimated := True;
    end;
  end;
end;

来自 How to animate a control roll out in Inno Setup（Martin Prikryl 的回答），以显示相同的效果，但从右到左并在确定的设置页面中。如何做到这一点？

Answer 1

在CurPageChanged中使用CurPageID到select在什么页面显示动画。

[Code]

function SetTimer(hWnd: longword; nIDEvent, uElapse: LongWord; lpTimerFunc: LongWord):
  LongWord; external 'SetTimer@user32.dll stdcall';
function KillTimer(hWnd, nIDEvent: LongWord): LongWord;
  external 'KillTimer@User32.dll stdcall';

var
  AnimationTimer: LongWord;

procedure AnimationTimerProc(
  H: LongWord; Msg: LongWord; IdEvent: LongWord; Time: LongWord);
var
  L: Integer;
begin
  L := WizardForm.MainPanel.Left - ScaleX(5);
  if L < 0 then
  begin
    L := 0;
    KillTimer(0, AnimationTimer);
  end;
  WizardForm.MainPanel.Left := L;
end;

procedure CurPageChanged(CurPageID: Integer);
begin
  if CurPageID = wpReady then
  begin
    AnimationTimer := SetTimer(0, 0, 5, CreateCallback(@AnimationTimerProc));
    WizardForm.MainPanel.Left := WizardForm.MainPanel.Width;
  end;
end;

对于 CreateCallback function, you need Inno Setup 6. If you are stuck with Inno Setup 5, you can use WrapCallback function from InnoTools InnoCallback 库。
