Detailed Description
The QPdfWriter class is a class to generate PDFs that can be used as a paint device.
QPdfWriter generates PDF out of a series of drawing commands using QPainter. The newPage() method can be used to create several pages.
Member Function Documentation
QPdfWriter::QPdfWriter(const QString & filename)
Constructs a PDF writer that will write the pdf to filename.
QPdfWriter::QPdfWriter(QIODevice * device)
Constructs a PDF writer that will write the pdf to device.
QPdfWriter::~QPdfWriter()
Destroys the pdf writer.
QString QPdfWriter::creator() const
Returns the creator of the document.
See also setCreator().
[virtual] bool QPdfWriter::newPage()
Reimplemented from QPagedPaintDevice::newPage().
QPageLayout QPdfWriter::pageLayout() const
Returns the current page layout. Use this method to access the current QPageSize, QPageLayout::Orientation, QMarginsF, fullRect() and paintRect().
Note that you cannot use the setters on the returned object, you must either call the individual QPdfWriter methods or use setPageLayout().
This function was introduced in Qt 5.3.
See also setPageLayout(), setPageSize(), setPageOrientation(), and setPageMargins().
[virtual protected] QPaintEngine * QPdfWriter::paintEngine() const
Reimplemented from QPaintDevice::paintEngine().
int QPdfWriter::resolution() const
Returns the resolution of the PDF in DPI.
This function was introduced in Qt 5.3.
See also setResolution().
void QPdfWriter::setCreator(const QString & creator)
Sets the creator of the document to creator.
See also creator().
bool QPdfWriter::setPageLayout(const QPageLayout & newPageLayout)
Sets the PDF page layout to newPageLayout.
You should call this before calling QPainter::begin(), or immediately before calling newPage() to apply the new page layout to a new page. You should not call any painting methods between a call to setPageLayout() and newPage() as the wrong paint metrics may be used.
Returns true if the page layout was successfully set to newPageLayout.
This function was introduced in Qt 5.3.
See also pageLayout().
bool QPdfWriter::setPageMargins(const QMarginsF & margins)
Set the PDF page margins in the current page layout units.
You should call this before calling QPainter::begin(), or immediately before calling newPage() to apply the new margins to a new page. You should not call any painting methods between a call to setPageMargins() and newPage() as the wrong paint metrics may be used.
To get the current page margins use pageLayout().pageMargins().
Returns true if the page margins were successfully set to margins.
This function was introduced in Qt 5.3.
See also pageLayout().
bool QPdfWriter::setPageMargins(const QMarginsF & margins, QPageLayout::Unit units)
Set the PDF page margins defined in the given units.
You should call this before calling QPainter::begin(), or immediately before calling newPage() to apply the new margins to a new page. You should not call any painting methods between a call to setPageMargins() and newPage() as the wrong paint metrics may be used.
To get the current page margins use pageLayout().pageMargins().
Returns true if the page margins were successfully set to margins.
This function was introduced in Qt 5.3.
See also pageLayout().
bool QPdfWriter::setPageOrientation(QPageLayout::Orientation orientation)
Sets the PDF page orientation.
The page orientation is used to define the orientation of the page size when obtaining the page rect.
You should call this before calling QPainter::begin(), or immediately before calling newPage() to apply the new orientation to a new page. You should not call any painting methods between a call to setPageOrientation() and newPage() as the wrong paint metrics may be used.
To get the current QPageLayout::Orientation use pageLayout().pageOrientation().
Returns true if the page orientation was successfully set to orientation.
This function was introduced in Qt 5.3.
See also pageLayout().
bool QPdfWriter::setPageSize(const QPageSize & pageSize)
Sets the PDF page size to pageSize.
To get the current QPageSize use pageLayout().pageSize().
You should call this before calling QPainter::begin(), or immediately before calling newPage() to apply the new page size to a new page. You should not call any painting methods between a call to setPageSize() and newPage() as the wrong paint metrics may be used.
Returns true if the page size was successfully set to pageSize.
This function was introduced in Qt 5.3.
See also pageLayout().
void QPdfWriter::setResolution(int resolution)
Sets the PDF resolution in DPI.
This setting affects the coordinate system as returned by, for example QPainter::viewport().
This function was introduced in Qt 5.3.
See also resolution().
void QPdfWriter::setTitle(const QString & title)
Sets the title of the document being created to title.
See also title().
QString QPdfWriter::title() const
Returns the title of the document.
See also setTitle().
