TabTip.exe（虚拟键盘）在 Windows 10 上的大小和位置？

Question

需要确定 TabTip.exe（虚拟键盘）在 windows 10 上的大小（宽度、高度）和位置（左、上）？

任务是移动所有组件所在的面板，使输入焦点转移到的输入字段位于虚拟键盘上方。

使用Windows10不在admin下，但是编译的项目是运行作为admin！

以下解决方案在 Windows 7、Windows 8 中有效，在 Windows 10 中无效：

uses ..., Winapi.Windows, Winapi.Dwmapi
...
procedure TForm1.SizeKeyboard;
var KeyBoardRect: TRect;
    KeyboardWindow : HWND;
begin
  KeyboardWindow := FindWindow('IPTip_Main_Window', nil);
  if (KeyboardWindow <> 0) then
    KeyBoardRect := GetRect1(KeyboardWindow);
  ...
end;
...

function TForm1.GetRect1(AKeyboardWindow : HWND): Trect;
var KeyBoardRect: Trect;
begin
    GetWindowRect(AKeyboardWindow, KeyBoardRect);
    Result := KeyBoardRect;
end;


function TForm1.GetRect2(AKeyboardWindow : HWND): Trect;
var KeyBoardRect: Trect;
begin
    DwmGetWindowAttribute(AKeyboardWindow, DWMWA_EXTENDED_FRAME_BOUNDS,     @KeyBoardRect, sizeof(KeyBoardRect));

    Result :=  KeyBoardRect;
end;

但是

Windows 10 触摸键盘是一个 UWP 应用程序。 UWP 应用程序没有原生 windows，无法通过 HWND 引用。您可以使用 UI 自动化来获取触摸键盘的边框 Get size of Windows 10 touch keyboard window!

已加载类型库 - UIAutomationClient 接口 IUIAutomation，IUIAutomationElement (UIAutomationClient_TLB)

function TForm1.getRect4(AKeyboardWindow : HWND): Trect;
var AUTOMATION : IUIAutomation;
  Root : IUIAutomationElement;
  rRect:UIAutomationClient_TLB.tagRECT;
begin
    AUTOMATION := CoCUIAutomation.Create;
    AUTOMATION.GetRootElement(Root);
    AUTOMATION.ElementFromHandle(Pointer(AKeyboardWindow), Root);
    Root.Get_CurrentBoundingRectangle(rRect);
    Result :=  TRect(rRect);
end;

function TForm1.getRect5(AKeyboardWindow : HWND): Trect;
var AUTOMATION : IUIAutomation;
  Root : IUIAutomationElement;
  olRect: OleVariant;
  rRect:UIAutomationClient_TLB.tagRECT;
begin
  AUTOMATION := CoCUIAutomation.Create;
  AUTOMATION.GetRootElement(Root);
  AUTOMATION.ElementFromHandle(Pointer(AKeyboardWindow), Root);
  Root.GetCurrentPropertyValue(BoundingRectangle, olRect);
  AUTOMATION.VariantToRect(olRect, rRect);

  Result :=  TRect(rRect);
end;

键盘调用

function ExpandEnvironmentVar(var Value: string): Boolean;
var
  R: Integer;
  Expanded: string;

procedure StrResetLength(var S: string);
  var
    I: Integer;
  begin
    for I := 0 to Length(S) - 1 do
      if S[I + 1] = #0 then
      begin
        SetLength(S, I);
        Exit;
      end;
  end;

begin
  SetLength(Expanded, 1);
  R := ExpandEnvironmentStrings(PChar(Value), PChar(Expanded), 0);
  SetLength(Expanded, R);
  Result := ExpandEnvironmentStrings(PChar(Value), PChar(Expanded), R) <> 0;
  if Result then
  begin
    StrResetLength(Expanded);
    Value := Expanded;
  end;
end;



procedure TForm1.btnCloseClick(Sender: TObject);
var
  MyHandle1: THandle;
begin
  MyHandle1 := FindWindow('IPTip_Main_Window', nil);
  if MyHandle1 <> 0 then
    PostMessage(MyHandle1, WM_SYSCOMMAND, SC_CLOSE, 0);
end;



procedure TForm1.btnOpenClick(Sender: TObject);
var
  S: string;
begin
  btnClose.Click;
  S := '%CommonProgramW6432%\microsoft shared\ink\tabtip.exe';
  ExpandEnvironmentVar(S);
  ShellExecute(0, PChar('open'), PChar(S), nil, nil, SW_SHOWNORMAL);
end;

没有成功(left = 0 top = 0 width = 0 height = 0)！有没有人做过这样的事情，或者他知道该怎么办？

Answer 1

您应该实施 IFrameworkInputPaneHandler：

Enables an app to be notified when the input pane (the on-screen keyboard or handwriting panel) is being shown or hidden. This allows the app window to adjust its display so that no input areas (such as a text box) are obscured by the input pane.
