QPdfView Class

Detailed Description

QPdfView is a PDF viewer widget that offers a user experience similar to many common PDF viewer applications, with two modes. In the MultiPage mode, it supports flicking through the pages in the entire document, with narrow gaps between the page images. In the SinglePage mode, it shows one page at a time.

Property Documentation

 

[since 6.6] currentSearchResultIndex : int

If this property is set to a positive number, and searchModel is set, QPdfView draws a frame around the search result provided by QPdfSearchModel at the given index. For example, if QPdfSearchModel is used as the model for a QListView, you can keep this property updated by connecting QItemSelectionModel::currentChanged() from QListView::selectionModel() to a function that will in turn call this function.

By default it is -1, so that no search results are framed.

This property was introduced in Qt 6.6.

Access functions:

  • int currentSearchResultIndex() const

  • void setCurrentSearchResultIndex(int currentResult)

Notifier signal:

  • void currentSearchResultIndexChanged(int currentResult)

document : QPdfDocument*

This property holds the document to be viewed.

Access functions:

  • *document() const

  • void setDocument( *document)

Notifier signal:

  • void documentChanged( *document)

documentMargins : QMargins

This property holds the margins around the page view.

Access functions:

  • documentMargins() const

  • void setDocumentMargins( margins)

Notifier signal:

  • void documentMarginsChanged( documentMargins)

pageMode : PageMode

This property holds whether to show one page at a time, or all pages in the document. The default is SinglePage.

Access functions:

This property was introduced in Qt 6.6.

Access functions:

  • void setSearchModel( *searchModel)

Notifier signal:

  • void setZoomFactor( factor)

Notifier signal:

  • void zoomFactorChanged( zoomFactor)

zoomMode : ZoomMode

This property indicates whether to use a custom size for the page(s), or zoom them to fit to the view. The default is CustomZoom.
