expand all in page

Description

An object of the mlreportgen.ppt.ContentPlaceholder class represents a content placeholder in a slide. You can replace a content placeholder with a picture, table, or one or more paragraphs.

The PPT API creates a ContentPlaceholder object when you add a slide to a presentation and the slide layout has a content placeholder. In the default PPT API, these layouts have one or more content placeholders:

  • 'Title and Content'

  • 'Two Content'

  • 'Comparison'

  • 'Content with Caption'

To find a ContentPlaceholder object, use the find method of the slide that contains the content placeholder. To replace the content placeholder with a picture, table, or one or more paragraphs, use the replace method of the ContentPlaceholder object. For a picture or table, the replace method replaces the ContentPlaceholder object with an mlreportgen.ppt.Picture or mlreportgen.ppt.Table object, respectively. For paragraphs, the PPT API does not replace the ContentPlaceholder object. It adds mlreportgen.ppt.Paragraph objects as children of the ContentPlaceholder object.

When you replace a ContentPlaceholder object with a Table or Picture object, some of the ContentPlaceholder object properties do not apply to the replacement content. For details, see Properties.

Note

If you replace a content placeholder with a picture, Microsoft® PowerPoint® adjusts the size of the content placeholder to accommodate the size of the picture. If you want the placeholder position and size to be fixed in a slide, use a slide with a picture placeholder. See mlreportgen.ppt.PicturePlaceholder.

The mlreportgen.ppt.ContentPlaceholder class is a handle class.

Open Live Script

Add four Title and Content slides to a presentation. Replace the content placeholder of the first slide with text, the second slide with a table, the third slide with a picture, and the fourth slide with a multilevel list.

Import the PPT package so that you do not have to use long, fully qualified names for the PPT API classes.

import mlreportgen.ppt.*

Create a presentation.

ppt = Presentation("myContentPlaceholderPresentation.pptx");
open(ppt);

Add a slide with a Title and Content layout.

slide1 = add(ppt,"Title and Content");

Use the find method of the slide object to find the placeholder object that has the name Title.

titlePlaceholderObj1 = find(slide1,"Title");

The find method returns an mlreportgen.ppt.TextBoxPlaceholder object.

Replace the placeholder content with the title text.

replace(titlePlaceholderObj1,"Content Replaced with Paragraph");

Use the find method of the slide object to find the placeholder object that has the name Content.

contentPlaceholderObj1 = find(slide1,"Content");

The find method returns an mlreportgen.ppt.ContentPlaceholder object.

Replace the placeholder content with a paragraph.

replace(contentPlaceholderObj1,Paragraph("This is my paragaph"));

Add a second slide with a Title and Content layout.

slide2 = add(ppt,"Title and Content");

Replace the placeholder for the title with the title text.

titlePlaceholderObj2 = find(slide2,"Title");
replace(titlePlaceholderObj2,"Content Replaced with Table for Order 2 Magic Square");

Replace the content placeholder with a table.

contentPlaceholderObj2 = find(slide2,"Content");
replace(contentPlaceholderObj2,Table(magic(2)));

Add a third slide with a Title and Content layout.

slide3 = add(ppt,"Title and Content");

Replace the placeholder for the title with the title text.

titlePlaceholderObj3 = find(slide3,"Title");
replace(titlePlaceholderObj3,"Content Replaced with Picture of Peppers");

Replace the content placeholder with a picture.

contentPlaceholderObj3 = find(slide3,"Content");
replace(contentPlaceholderObj3,Picture("peppers.png"));

Add a fourth slide with a Title and Content layout.

slide4 = add(ppt,"Title and Content");

Replace the placeholder for the title with the title text.

titlePlaceholderObj4 = find(slide4,"Title");
replace(titlePlaceholderObj4,"Content Replaced with a Multilevel List");

Create content for a multilevel list. You can represent a multilevel list as a cell array that contains one or more cell arrays that represent sublists. Use an mlreportgen.ppt.Paragraph object to format an item in the list.

greenTea = Paragraph("Green Tea");
greenTea.FontColor = "green";

multilevelContent = { ...
    "Coffee", ...
    "Tea", ...
    { ...
        "Black Tea", ...
        greenTea, ...
    }, ...
    "Milk", ...
    };

Replace the Content placeholder with the multilevel list content.

contentPlaceholderObj4 = find(slide4,"Content");
replace(contentPlaceholderObj4,multilevelContent);

Close and view the presentation.

close(ppt);
rptview(ppt);

Here are the generated slides:

Tips

  • When you replace placeholder content in a presentation and then use the presentation as a template for a new presentation, the object that the PPT API creates for the content in the new presentation depends on the type of content, as shown in the table.

    Replacement ContentClass of Object in New Presentation
    picturemlreportgen.ppt.TemplatePicture
    tablemlreportgen.ppt.TemplateTable
    paragraphmlreportgen.ppt.ContentPlaceholder

    For more information, see Add and Replace Presentation Content.

  • To see the placeholder objects that the PPT API creates for a slide object, view the Children property of the slide. For example, when you add a Title and Content slide to a presentation, the Children property is an array that contains an mlreportgen.ppt.TextBoxPlaceholder object and an mlreportgen.ppt.ContentPlaceholder object.

    ppt = mlreportgen.ppt.Presentation("test.pptx");
open(ppt);
slide = add(ppt,"Title and Content");
