## Detailed Description

The QAbstractPrintDialog class provides a base implementation for print dialogs used to configure printers.

This class implements getter and setter functions that are used to customize settings shown in print dialogs, but it is not used directly. Use QPrintDialog to display a print dialog in your application.

See also QPrintDialog and QPrinter.

## Member Type Documentation

### enum QAbstractPrintDialog::PrintDialogOption
flags QAbstractPrintDialog::PrintDialogOptions

Used to specify which parts of the print dialog should be visible.

Constant | Value | Description
--- | --- | ---
`QAbstractPrintDialog::None` | `0x0000` | None of the options are enabled.
`QAbstractPrintDialog::PrintToFile` | `0x0001` | The print to file option is enabled.
`QAbstractPrintDialog::PrintSelection` | `0x0002` | The print selection option is enabled.
`QAbstractPrintDialog::PrintPageRange` | `0x0004` | The page range selection option is enabled.
`QAbstractPrintDialog::PrintShowPageSize` | `0x0008` | Show the page size + margins page only if this is enabled.
`QAbstractPrintDialog::PrintCollateCopies` | `0x0010` | The collate copies option is enabled
`QAbstractPrintDialog::PrintCurrentPage` | `0x0040` | The print current page option is enabled

This value is obsolete and does nothing since Qt 4.5:

Constant | Value | Description
--- | --- | ---
`QAbstractPrintDialog::DontUseSheet` | `0x0020` | In previous versions of Qt, exec() the print dialog would create a sheet by default the dialog was given a parent. This is no longer supported in Qt 4.5. If you want to use sheets, use QPrintDialog::open() instead.

The PrintDialogOptions type is a typedef for QFlags<PrintDialogOption>. It stores an OR combination of PrintDialogOption values.

### enum QAbstractPrintDialog::PrintRange

Used to specify the print range selection option.

Constant | Value | Description
--- | --- | ---
`QAbstractPrintDialog::AllPages` | `0` | All pages should be printed.
`QAbstractPrintDialog::Selection` | `1` | Only the selection should be printed.
`QAbstractPrintDialog::PageRange` | `2` | The specified page range should be printed.
`QAbstractPrintDialog::CurrentPage` | `3` | Only the currently visible page should be printed.

## Member Function Documentation

### QAbstractPrintDialog::QAbstractPrintDialog(QPrinter *printer, QWidget *parent = Q_NULLPTR)

Constructs an abstract print dialog for printer with parent as parent widget.

### `[pure virtual]` int QAbstractPrintDialog::exec()

This virtual function is called to pop up the dialog. It must be reimplemented in subclasses.

### int QAbstractPrintDialog::fromPage() const

Returns the first page to be printed By default, this value is set to 0.

### int QAbstractPrintDialog::maxPage() const

Returns the maximum page in the page range. As of Qt 4.4, this function returns INT_MAX by default. Previous versions returned 1 by default.

### int QAbstractPrintDialog::minPage() const

Returns the minimum page in the page range. By default, this value is set to 1.

### PrintRange QAbstractPrintDialog::printRange() const

Returns the print range.

See also setPrintRange().

### QPrinter *QAbstractPrintDialog::printer() const

Returns the printer that this printer dialog operates on.

### void QAbstractPrintDialog::setFromTo(int from, int to)

Sets the range in the print dialog to be from from to to.

### void QAbstractPrintDialog::setMinMax(int min, int max)

Sets the page range in this dialog to be from min to max. This also enables the PrintPageRange option.

### void QAbstractPrintDialog::setOptionTabs(const QList<QWidget *> &tabs)

Set a list of widgets as tabs to be shown on the print dialog, if supported.

Currently this option is only supported on X11.

Setting the option tabs will transfer their ownership to the print dialog.

This function was introduced in Qt 4.4.

### void QAbstractPrintDialog::setPrintRange(PrintRange range)

Sets the print range option in to be range.

See also printRange().

### int QAbstractPrintDialog::toPage() const

Returns the last page to be printed. By default, this value is set to 0.
