典型的なコンポーネントの例

PyLAFでは１ビュー１パラメータパネルの典型的なコンポーネントを簡単に作成するため、 サポートクラスEasyComponentを用意しています。 以下は正弦波を発生させるコンポーネントです。

以下は２入力を積算するミキサーコンポーネントです。

  22.      vw = Embed(frm,Spectrum,text='FGSIN:IF'); vw.pack(side=Tkinter.TOP)

  24.      im = Embed(master,FGSIN,text='FGSIN:IF'); im.pack(side=Tkinter.RIGHT)

  33.      lo.component.trigger()
  34.      
  35.  if __name__ == '__main__':
  36.      test_embed(Tkinter.Tk())
  37.      Tkinter.mainloop()

典型的なワークセットの例

PyLAFでは簡単にコンポーネントを連携動作させるスクリプト（ワークセットと呼んでいます）を作成できます。 以下はFGSINとMIXERを使って作成したAM変調ワークセットの例です。 複数のコンポーネントがそれぞれ別々のトップレベルウィンドウを使って表示されます。

modam_set1.py
  1.  # coding: utf-8
  2.  import Tkinter
  3.  from PyLAF import App
  4.  from FGSIN import FGSIN
  5.  from MIXER import MIXER
  6.  
  7.  master = Tkinter.Tk()
  8.  
  9.  mx = App(master,MIXER); mx.master.title('MIXER:RF'); mx.pack()
  10.  lo = App(Tkinter.Toplevel(master),FGSIN); lo.master.title('FGSIN:LO'); lo.pack()
  11.  im = App(Tkinter.Toplevel(master),FGSIN); im.master.title('FGSIN:IF'); im.pack()
  12.  lo.freq.set(0.1)
  13.  im.bias.set(1.0)
  14.  lo.sig_out.link(mx.sig_a)
  15.  im.sig_out.link(mx.sig_b)
  16.  lo.dt.link(im.dt)
  17.  lo.tend.link(im.tend)
  18.  mx.component.trigger()
  19.  
  20.  Tkinter.mainloop()

ワークセットを単一のウィンドウにまとめたい場合、Embed(LabelFrame,Equipment)クラスを使ってコンポーネントを装置化します。

modam_set2.png

modam_set2.py
  1.  # coding: utf-8
  2.  import Tkinter
  3.  from PyLAF import Embed
  4.  from FGSIN import FGSIN
  5.  from MIXER import MIXER
  6.  
  7.  master = Tkinter.Tk()
  8.  master.title('MODULATION:AM')
  9.  
  10.  mx = Embed(master,MIXER,text='MIXER:RF'); mx.pack(side=Tkinter.RIGHT)
  11.  lo = Embed(master,FGSIN,text='FGSIN:LO'); lo.pack(side=Tkinter.RIGHT)
  12.  im = Embed(master,FGSIN,text='FGSIN:IF'); im.pack(side=Tkinter.RIGHT)
  13.  im.bias.set(1.0)
  14.  lo.freq.set(0.1)
  15.  lo.dt.link(im.dt)
  16.  lo.tend.link(im.tend)
  17.  lo.sig_out.link(mx.sig_a)
  18.  im.sig_out.link(mx.sig_b)
  19.  mx.component.trigger()
  20.  
  21.  Tkinter.mainloop()

EmbedとAppは混在できます。スペクトルを見たい場合、トップレベルウィンドウに スペアナを作成し、mixer.sig_outにスペアナのsig_inを接続すれば連携動作します。

modam_set3.py
  1.  # coding: utf-8
  2.  import Tkinter
  3.  from PyLAF import Embed, App, Spectrum
  4.  from FGSIN import FGSIN
  5.  from MIXER import MIXER
  6.  
  7.  master = Tkinter.Tk()
  8.  master.title('MODULATION:AM')
  9.  
  10.  frm = Tkinter.Frame(master); frm.pack(side=Tkinter.RIGHT)
  11.  mx = Embed(frm,MIXER,text='MIXER:RF'); mx.pack(side=Tkinter.TOP)
  12.  lo = Embed(master,FGSIN,text='FGSIN:LO'); lo.pack(side=Tkinter.RIGHT)
  13.  im = Embed(master,FGSIN,text='FGSIN:IF'); im.pack(side=Tkinter.RIGHT)
  14.  im.bias.set(1.0)
  15.  lo.freq.set(0.1)
  16.  lo.dt.link(im.dt)
  17.  lo.tend.link(im.tend)
  18.  lo.sig_out.link(mx.sig_a)
  19.  im.sig_out.link(mx.sig_b)
  20.  
  21.  vw = App(Tkinter.Toplevel(master),Spectrum); vw.master.title('Spectrum:RF'); vw.pack(side=Tkinter.TOP)
  22.  mx.sig_out.link(vw.sig_in)
  23.  mx.component.trigger()
  24.  
  25.  Tkinter.mainloop()

典型的な複合コンポーネントの例

サブコンポーネントを含んだ複合コンポーネントとしてまとめると、 他のコンポーネントと同じ様に利用することができます。 ワークセットを恒久的に使いたい場合などに使います。
