ActiveX 控件用于演示文稿中。Aspose.Slides for Python via .NET 允许您管理 ActiveX 控件，但管理起来比普通演示形状要复杂且不同。从 Aspose.Slides for Python via .NET 6.9.0 开始，该组件支持管理 ActiveX 控件。此时，您可以访问已添加到演示文稿中的 ActiveX 控件，并通过其各种属性进行修改或删除。请记住，ActiveX 控件不是形状，并且不属于演示文稿的 IShapeCollection，而是单独的 IControlCollection。本文展示了如何与它们一起工作。
修改 ActiveX 控件
要管理幻灯片上的简单 ActiveX 控件，例如文本框和简单命令按钮：
- 创建 Presentation 类的实例并加载包含 ActiveX 控件的演示文稿。
- 通过索引获取幻灯片引用。
- 通过访问 IControlCollection 来访问幻灯片中的 ActiveX 控件。
- 使用 ControlEx 对象访问 TextBox1 ActiveX 控件。
- 更改 TextBox1 ActiveX 控件的不同属性，包括文本、字体、字体高度和框架位置。
- 访问第二个访问控件 CommandButton1。
- 更改按钮标题、字体和位置。
- 移动 ActiveX 控件框架的位置。
- 将修改后的演示文稿写入 PPTX 文件。
下面的代码片段更新演示文稿幻灯片上的 ActiveX 控件，如下所示。
import aspose.slides as slides
import aspose.pydrawing as draw

# 访问包含 ActiveX 控件的演示文稿
with slides.Presentation(path + "ActiveX.pptm") as presentation:
# 访问演示文稿中的第一张幻灯片

# 更改 TextBox 文本
control = slide.controls[0]
if control.name == "TextBox1" and control.properties != None:
newText = "修改后的文本"
control.properties.remove("Value")
control.properties.add("Value", newText)
# 更换替代图像。Powerpoint将在 ActiveX 激活期间替换此图像，因此有时可以保持图像不变。

# 保存带有编辑过的 ActiveX 控件的演示文稿

添加 ActiveX 媒体播放器控件
要添加 ActiveX 媒体播放器控件，请执行以下步骤：
- 创建 Presentation 类的实例，并加载包含媒体播放器 ActiveX 控件的示例演示文稿。
- 创建目标 Presentation 类的实例，并生成空演示文稿实例。
- 将模板演示文稿中带有媒体播放器 ActiveX 控件的幻灯片克隆到目标 Presentation。
- 访问目标 Presentation 中的克隆幻灯片。
- 通过访问 IControlCollection 获取幻灯片上的 ActiveX 控件。
- 访问媒体播放器 ActiveX 控件并使用其属性设置视频路径。
- 将演示文稿保存为 PPTX 文件。
import aspose.slides as slides
# 实例化表示 PPTX 文件的 Presentation 类
with slides.Presentation(path + "template.pptx") as presentation:
# 创建空演示文稿实例
with slides.Presentation() as newPresentation:
# 移除默认幻灯片
newPresentation.slides.remove_at(0)
# 克隆带有媒体播放器 ActiveX 控件的幻灯片
newPresentation.slides.insert_clone(0, presentation.slides[0])
# 访问媒体播放器 ActiveX 控件并设置视频路径
prop = newPresentation.slides[0].controls[0].properties
prop.remove("URL")
prop.add("URL", "Wildlife.mp4")
# 保存演示文稿
newPresentation.save("LinkingVideoActiveXControl_out.pptx", slides.export.SaveFormat.PPTX)
