如何在ACT當中將設計名稱加到下拉選單當中

當我們在App Builder建立了選單之後，可以輸出.xml及.py檔。在.xml當中<step>層級底下加入<onrefresh></onrefresh>標籤，並在當中呼叫RefreshChoice函數。

combobox.xml的內容

<!-- autogenerated by XmlWriter ( 15/11/2020 05:32:32 ) -->
<extension name="combobox">
  <imagedirectory>.</imagedirectory>
  <guid>b39d25c3-456b-47db-93fa-31e4f172e169</guid>
  <script src="IDEGeneratedMain.py" />
  <wizard name="cb" caption="cb" version="1" context="ElectronicsDesktop">
    <step name="Step_1" version="0" caption="Step_1">
      <property control="select" name="design" caption="design" persistent="False" parameterizable="False">
        <attributes options="Refresh" />  
      </property>
      
      <callbacks>
        <onrefresh>RefreshChoice</onrefresh>
      </callbacks>     
    </step>
  </wizard>
</extension>

在.py檔當中，定義RefreshChoice函數，當中讀取專案底下所有的設計並加到下拉選單當中。

IDEGeneratedMain.py的內容

def onupdateStep(step):
    pass

def RefreshChoice(step):
    Designs_Field = step.Properties["design"]
    Designs_Field.Options.Clear()

    ActiveProject = oDesktop.GetActiveProject()
    DesignList = ActiveProject.GetTopDesignList()
    if len(DesignList) != 0:
        ActiveDesign = ActiveProject.GetActiveDesign()

        for design in DesignList:
            Designs_Field.Options.Add(design)

當啟動ACT之後，點一下下拉選單的Refresh選項之後，下拉選單便會更新加入所有的設計名稱。
