Class DrawForms

Introduction

The DrawForms class represents the collection of forms in a Draw document.

This class contains several python magic methods to make it behave like a collection.

Getting Number of Forms

To get the number of pages in a draw document, use the built in len() method:

>>> doc = DrawDoc(Draw.create_draw_doc())
>>> draw_page = doc.slides[0]
>>> len(draw_page.forms)
0
>>>draw_page.forms.add_form()
>>> len(draw_page.forms)
1

Getting a form

There are several ways to get a form from a Calc sheet. The simplest is to use the [] method:

Get Form by Index.

>>> doc = DrawDoc(Draw.create_draw_doc())
>>> draw_page = doc.slides[0]
>>> if len(draw_page.forms) == 0:
...   draw_page.forms.add_form()
>>> form = draw_page.forms[0]
<ooodev.draw.DrawForm object at 0x7f8b1c0b4a90>

Get Form by Name.

>>> doc = DrawDoc(Draw.create_draw_doc())
>>> draw_page = doc.slides[0]
>>> if len(draw_page.forms) == 0:
...   draw_page.forms.add_form("MyForm")
>>> form = draw_page.forms["MyForm"]
<ooodev.draw.DrawForm object at 0x7f8b1c0b4a90>

To get the last form in a sheet, use the -1 index:

>>> doc = DrawDoc(Draw.create_draw_doc())
>>> draw_page = doc.slides[0]
>>> if len(draw_page.forms) == 0:
...   draw_page.forms.add_form()
>>> form = draw_page.forms[-1]
<ooodev.draw.DrawForm object at 0x7f8b1c0b4a90>

Deleting a form

To delete a form, use the del keyword:

Delete by form index.

>>> del doc.slides[0].draw_page.forms[1]

Delete by form name.

>>> del doc.slides[0].draw_page.forms["MyForm"]

Iterating over forms

To iterate over the forms in a sheet, use the for keyword:

>>> for form in doc.slides[0].draw_page.forms:
...     print(form.name)
MyForm

An example can be found on Live LibreOffice Python UNO Examples. Example: Build Form.

Class Declaration

class ooodev.draw.DrawForms(owner, forms, lo_inst=None)[source]

Bases: LoInstPropsPartial, OfficeDocumentPropPartial, FormsComp, QiPartial, ServicePartial, TheDictionaryPartial

Class for managing Draw Forms.

This class is Enumerable and returns DrawForm instance on iteration.

for sheet in doc.sheets:
    sheet["A1"].set_val("test")
    assert sheet["A1"].get_val() == "test"

This class also as index access and returns CalcSheet instance.

sheet = doc.sheets["Sheet1"]
# or set the value of cell A2 to TEST
doc.sheets[0]["A2"].set_val("TEST")

# get the last sheet of the document
last_sheet = doc.sheets[-1]

# get the second last sheet of the document
second_last_sheet = doc.sheets[-2]

# get the number of sheets
num_sheets = len(doc.sheets)

New in version 0.18.3.
