Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property pageCountᅟ: int

This property holds the number of pages in the loaded document or 0 if no document is loaded.

Access functions:

• pageCount()

• Signal pageCountChanged()

property pageModelᅟ: QAbstractListModel

This property holds an instance of QAbstractListModel to provide page-specific metadata, containing one row for each page in the document.

PageModelRole

Access functions:

• pageModel()

• Signal pageModelChanged()

property passwordᅟ: str

This property holds the document password.

If the document is protected by a password, the user must provide it, and the application must set this property. Otherwise, it’s not needed.

Access functions:

• password()

• setPassword()

• Signal passwordChanged()

property statusᅟ: QPdfDocument.Status

This property holds the current status of the document.

Access functions:

• status()

• Signal statusChanged()

__init__(parent)

Parameters:

parent – QObject

Constructs a new document with parent object parent.

__init__()

close()

Closes the document.

error()

Return type:

Error

Returns the type of error if status is Error, or NoError if there is no error.

getAllText(page)

Parameters:

page – int

Return type:

QPdfSelection

Returns all the text and its bounds on the given page.

getSelection(page, start, end)

Parameters:

• page – int

• start – QPointF

• end – QPointF

Return type:

QPdfSelection

Returns information about the text on the given page that can be found between the given start and end points, if any.

getSelectionAtIndex(page, startIndex, maxLength)

Parameters:

• page – int

• startIndex – int

• maxLength – int

Return type:

QPdfSelection

Returns information about the text on the given page that can be found beginning at the given startIndex with at most maxLength characters.

load(device)

Parameters:

device – QIODevice

Loads the document contents from device.

load(fileName)

Parameters:

fileName – str

Return type:

Error

Loads the document contents from fileName.

metaData(field)

Parameters:

field – MetaDataField

Return type:

object

Returns the meta data of the document for the given field.

pageCount()

Return type:

int

Getter of property pageCountᅟ .

pageCountChanged(pageCount)

Parameters:

pageCount – int

Notification signal of property pageCountᅟ .

pageIndexForLabel(label)

Parameters:

label – str

Return type:

int

Returns the index of the page that has the label, or -1 if not found.

See also

pageLabel()

pageLabel(page)

Parameters:

page – int

Return type:

str

Returns the page number to be used for display purposes.

For example, a document may have multiple sections with different numbering. Perhaps the preface uses roman numerals, the body starts on page 1, and the appendix starts at A1. Whenever a PDF viewer shows a page number, to avoid confusing the user it should be the same “number” as is printed on the corner of the page, rather than the zero-based page index that we use in APIs (assuming the document author has made the page labels match the printed numbers).

If the document does not have custom page numbering, this function returns page + 1.

pageIndexForLabel()

pageModel()

Return type:

QAbstractListModel

Getter of property pageModelᅟ .

pageModelChanged()
