ウィンドウを透明化する

BrowserWindow のコンストラクタに渡すオプションとして transparent: trueframe: false を指定する。

const win = new BrowserWindow({ transparent: true, frame: false });

Limitations

  • You can not click through the transparent area. We are going to introduce an API to set window shape to solve this, see our issue for details.
  • Transparent windows are not resizable. Setting resizable to true may make a transparent window stop working on some platforms.
  • The blur filter only applies to the web page, so there is no way to apply blur effect to the content below the window (i.e. other applications open on the user’s system).
  • On Windows operating systems, transparent windows will not work when DWM is disabled.
  • On Linux, users have to put --enable-transparent-visuals --disable-gpu in the command line to disable GPU and allow ARGB to make transparent window, this is caused by an upstream bug that alpha channel doesn’t work on some NVidia drivers on Linux.
  • On Mac, the native window shadow will not be shown on a transparent window.
