إنشاء العروض التقديمية وإدارتها

توضّح هذه الصفحة كيفية تنفيذ مهام معيّنة عالية المستوى تتعلّق بالعروض التقديمية، مثل:

  • إنشاء عرض تقديمي
  • نسخ عرض تقديمي حالي

توضّح الفقرات التالية هذه المهام بالتفصيل.

إنشاء عرض تقديمي فارغ

لإنشاء عرض تقديمي، استخدِم الأسلوب create في مجموعة presentations، كما هو موضّح في المثال التالي.

ينشئ هذا المثال عرضًا تقديميًا فارغًا بعنوان محدّد.

العمل مع مجلدات Google Drive

لا يتوفّر خيار لإنشاء عرض تقديمي مباشرةً ضمن مجلد محدّد في Drive باستخدام Google Slides API. يتم تلقائيًا حفظ العرض التقديمي الذي تم إنشاؤه في المجلد الجذر للمستخدم على Drive.

ومع ذلك، هناك خياران بديلان لحفظ ملف في مجلد على Drive:

  • بعد إنشاء العرض التقديمي، يمكنك نقله إلى مجلد محدّد باستخدام الطريقة files.update من واجهة برمجة التطبيقات Drive API. لمزيد من المعلومات عن نقل الملفات، يُرجى الاطّلاع على مقالة نقل الملفات بين المجلدات.
  • أضِف عرضًا تقديميًا فارغًا إلى مجلد باستخدام الطريقة files.create في Drive API، مع تحديد application/vnd.google-apps.presentation على أنّه mimeType. لمزيد من المعلومات عن إنشاء الملفات، يُرجى الاطّلاع على مقالة إنشاء ملف في مجلد.

في أيّ من الخيارَين، عليك إضافة نطاقات Drive API المناسبة لمنح الإذن بالطلب.

لنقل ملف أو إنشائه في مجلد مساحة تخزين سحابي مشتركة، يُرجى الرجوع إلى مقالة إتاحة مساحة التخزين السحابي المشتركة.

نسخ عرض تقديمي حالي

لنسخ عرض تقديمي، استخدِم الطريقة files().copy في Drive API.

ينسخ المثال التالي عرضًا تقديميًا حاليًا باستخدام سلسلة مقدَّمة لعنوان العرض التقديمي واسم ملف Drive الجديد.
