[macos] Firemonkey에서 “No Activate”양식을 만드는 방법

NSNonactivatingPanelMask 플래그 와 함께 NSPanel 을 사용할 수 있습니다 . fmx 형식의 NSView는 NSPanel의 자식이되어야합니다. Windows 및 Mac 플랫폼 모두에서 작동하는 도우미 클래스를 작성했습니다 ( XE4에서 작동 ).

unit NoActivateForm;

interface

uses Fmx.Forms, Fmx.Types

    ;

private
    form: TForm;
{$IFDEF POSIX}
    panel: NSPanel;
    timer: TTimer;  // for simulating mouse hover event
{$ENDIF}
    procedure SetPosition(const x, y: Integer);

상기 단위의 사용법 :

TNoActivateForm *naKeyboard; // global scope    
void __fastcall TfrmKeyboard::TfrmKeyboard(TObject *Sender)
{
    naKeyboard = new TNoActivateForm(frmKeyboard); // frmKeyboard is a normal fmx form
    naKeyboard->Visible = true;
}

frmKeyboard가 기본 양식 인 경우 양식 생성자에 위 코드를 넣지 말고 OnShow에 넣는 것이 좋습니다.

참고 : WindowHandleToPlatform은 XE3에 존재하지 않으므로 줄을 바꿀 수 있습니다.

window := NSWindow(NSWindowFromObjC(FmxHandleToObjC(Form.Handle)));

Var nswin:nswindow;

NSWin:= NSWindow(NSWindowFromObjC(FmxHandleToObjC(myform.Handle))); { get the NSWindow }
NSWin.setIgnoresMouseEvents(true);                                 { ignore mouse events }
