PowerPoint + VSTO 动态更改上下文菜单

Question

我想向上下文菜单添加一些按钮（可能还有其他类型的控件 - 我现在不确定），但前提是满足某些条件。因此，有可用的 Application.WindowBeforeRightClick 事件，但它仅在我单击幻灯片时触发，而不是在单击某些形状时触发。

到目前为止，我添加了一些 xml 作为彩带：

<?xml version="1.0" encoding="UTF-8"?>
<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui" onLoad="Ribbon_Load">
  <contextMenus>
    <contextMenu idMso="ContextMenuShape">
      <button id="button1" label="button1"/>
    </contextMenu>
    <contextMenu idMso="ContextMenuObjectsGroup">
      <button id="button2" label="Align vertical axes" onAction="AlignXAxis"  getVisible="ChangeCMObjectsGroupVisibility"/>
      <button id="button3" label="Align horizontal axes" onAction="AlignYAxis"  getVisible="ChangeCMObjectsGroupVisibility"/>
      <button id="button4" label="Align scale" onAction="MaxScale"  getVisible="ChangeCMObjectsGroupVisibility"/>
      <button id="button5" label="Add legend" onAction="Legend"  getVisible="ChangeCMObjectsGroupVisibility"/>
      <button id="button6" label="Adjust chart width" onAction="AdjustWidth"  getVisible="ChangeCMObjectsGroupVisibility"/>
      <button id="button7" label="Adjust chart height" onAction="AdjustHeight"  getVisible="ChangeCMObjectsGroupVisibility"/>
    </contextMenu>
  </contextMenus>
</customUI>

和代码：

private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
    Application.WindowBeforeRightClick += new PPT.EApplication_WindowBeforeRightClickEventHandler(Application_WindowBeforeRightClick);
    ribbon= (Ribbon1)CreateRibbonExtensibilityObject();
}

void Application_WindowBeforeRightClick(PPT.Selection Sel, ref bool Cancel)
{
    PPT.Selection selection= Globals.ThisAddIn.Application.ActiveWindow.Selection;
    if (selection.Type==PPT.PpSelectionType.ppSelectionShapes)
    {
        if (selection.ShapeRange.HasChart==MsoTriState.msoTrue)
        {
            ribbon.TurnOnChangeCMObjectsGroupVisibility();
        }
    }
}

是否可以检查所选形状的类型、hide/show/add/remove 控件然后显示正确的上下文菜单？

Answer 1

Application_WindowSelectionChange 事件将在您右键单击形状时触发。您可以在该事件处理程序中检查形状类型（或任何其他标准）。

为了更新上下文菜单，您需要使功能区失效。这会调用您的 ChangeCMObjectsGroupVisibility 回调并根据条件更新上下文菜单项的可见性。您可能需要使用全局变量向 ChangeCMObjectsGroupVisibility 回调提供已满足的标准。
