										<content:encoded><![CDATA[
<p>之前都是使用 tkinter 做 python 的 GUI，pyQt 因為要付費或是要開源，所以不適合商用. 替代解法是使用 pySide2, LGPL 可以不開源做商用。</p>



<p>LGPL 是自由軟體基金會 (Free Software Foundation, FSF) 針對函式庫類別程式所特別撰寫出來的自由軟體授權條款。</p>



<p>LGPL 的軟體進行任何調用、連接而非包含、修改後再利用，則可以商用時不需開源。</p>



<p>PySide2使用的是LGPL授權，引用的函式庫、模組都可以在商用的程式發布時合法使用。</p>



<p>PySide2 中的Qt Designer 則是可以在圖形介面中就直接產出靜態的Python 程式碼.</p>



<p>Qt Designer下載:<br><a href="https://build-system.fman.io/qt-designer-download">https://build-system.fman.io/qt-designer-download</a></p>



<p>Qt Designer is a tool for quickly building graphical user interfaces with widgets from the Qt GUI framework. It gives you a simple drag-and-drop interface for laying out components such as buttons, text fields, combo boxes and more.</p>



<p>Qt for Python:<br><a href="https://wiki.qt.io/Qt_for_Python">https://wiki.qt.io/Qt_for_Python</a></p>

<p>Mac 使用了程式 QWinFF, 使用的 qt 是支援 LGPL 的授權， 執行畫面如下:</p>
