From 49c7939b6b3472af756412324442170d0af5d08f Mon Sep 17 00:00:00 2001 From: Albert Astals Cid Date: Wed, 20 Dec 2017 10:41:33 +0100 Subject: [PATCH] Fix custom page size handling in the Unix print dialog There were several problems that i've fixed in a single commit since they are very interwinded * The dialog used QPageSize::Custom for two things, the custom sizes coming from the printer and the "user can write whatever size they want" size. Now only the printer custom sizes use QPageSize::Custom and we use m_realCustomPageSizeIndex for the "user can write whatever size they want" one. * The dialog stored the QPageSize id as the combo userData, that doesn't work when the printer has multiple custom sizes since they all share QPageSize::Custom so now it stores the QPageSize itself Task-number: QTBUG-58733 Change-Id: Ie640a07bb5e24b753db83c091c836e8af4ff126c --- src/printsupport/dialogs/qpagesetupdialog_unix.cpp | 30 ++++++++++++++-------- src/printsupport/dialogs/qpagesetupdialog_unix_p.h | 1 + 2 files changed, 20 insertions(+), 11 deletions(-) diff --git a/src/printsupport/dialogs/qpagesetupdialog_unix.cpp b/src/printsupport/dialogs/qpagesetupdialog_unix.cpp index 6f3bb0dd55..55ac913df8 100644 --- a/src/printsupport/dialogs/qpagesetupdialog_unix.cpp +++ b/src/printsupport/dialogs/qpagesetupdialog_unix.cpp @@ -234,10 +234,14 @@ QPageSetupWidget::QPageSetupWidget(QWidget *parent) m_printer(0), m_outputFormat(QPrinter::PdfFormat), m_units(QPageLayout::Point), - m_blockSignals(false) + m_blockSignals(false), + m_realCustomPageSizeIndex(-1) { m_ui.setupUi(this); + if (!QMetaType::hasRegisteredComparators()) + QMetaType::registerEqualsComparator(); + QVBoxLayout *lay = new QVBoxLayout(m_ui.preview); m_pagePreview = new QPagePreview(m_ui.preview); m_pagePreview->setPagePreviewLayout(1, 1); @@ -341,15 +345,18 @@ void QPageSetupWidget::initPageSizes() m_ui.pageSizeCombo->clear(); + m_realCustomPageSizeIndex = -1; + if (m_outputFormat == QPrinter::NativeFormat && !m_printerName.isEmpty()) { QPlatformPrinterSupport *ps = QPlatformPrinterSupportPlugin::get(); if (ps) { QPrintDevice printDevice = ps->createPrintDevice(m_printerName); const auto pageSizes = printDevice.supportedPageSizes(); for (const QPageSize &pageSize : pageSizes) - m_ui.pageSizeCombo->addItem(pageSize.name(), QVariant::fromValue(pageSize.id())); + m_ui.pageSizeCombo->addItem(pageSize.name(), QVariant::fromValue(pageSize)); if (m_ui.pageSizeCombo->count() > 0 && printDevice.supportsCustomPageSizes()) { - m_ui.pageSizeCombo->addItem(tr("Custom"), QVariant::fromValue(QPageSize::Custom)); + m_ui.pageSizeCombo->addItem(tr("Custom")); + m_realCustomPageSizeIndex = m_ui.pageSizeCombo->count() - 1; m_blockSignals = false; return; } @@ -359,10 +366,11 @@ void QPageSetupWidget::initPageSizes() // If PdfFormat or no available printer page sizes, populate with all page sizes for (int id = 0; id < QPageSize::LastPageSize; ++id) { if (QPageSize::PageSizeId(id) == QPageSize::Custom) { - m_ui.pageSizeCombo->addItem(tr("Custom"), QVariant::fromValue(QPageSize::Custom)); + m_ui.pageSizeCombo->addItem(tr("Custom")); + m_realCustomPageSizeIndex = m_ui.pageSizeCombo->count() - 1; } else { QPageSize pageSize = QPageSize(QPageSize::PageSizeId(id)); - m_ui.pageSizeCombo->addItem(pageSize.name(), QVariant::fromValue(pageSize.id())); + m_ui.pageSizeCombo->addItem(pageSize.name(), QVariant::fromValue(pageSize)); } } @@ -434,7 +442,9 @@ void QPageSetupWidget::updateWidget() m_ui.unitCombo->setCurrentIndex(m_ui.unitCombo->findData(QVariant::fromValue(m_units))); - m_ui.pageSizeCombo->setCurrentIndex(m_ui.pageSizeCombo->findData(QVariant::fromValue(m_pageLayout.pageSize().id()))); + const bool isCustom = m_ui.pageSizeCombo->currentIndex() == m_realCustomPageSizeIndex && m_realCustomPageSizeIndex != -1; + if (!isCustom) + m_ui.pageSizeCombo->setCurrentIndex(m_ui.pageSizeCombo->findData(QVariant::fromValue(m_pageLayout.pageSize()))); QMarginsF min; QMarginsF max; @@ -467,8 +477,6 @@ void QPageSetupWidget::updateWidget() m_ui.bottomMargin->setMaximum(max.bottom()); m_ui.bottomMargin->setValue(m_pageLayout.margins().bottom()); - bool isCustom = m_ui.pageSizeCombo->currentData().value() == QPageSize::Custom; - m_ui.pageWidth->setSuffix(suffix); m_ui.pageWidth->setValue(m_pageLayout.fullRect(m_units).width()); m_ui.pageWidth->setEnabled(isCustom); @@ -513,10 +521,10 @@ void QPageSetupWidget::pageSizeChanged() if (m_blockSignals) return; - QPageSize::PageSizeId id = m_ui.pageSizeCombo->currentData().value(); - if (id != QPageSize::Custom) { + if (m_ui.pageSizeCombo->currentIndex() != m_realCustomPageSizeIndex) { + const QPageSize pageSize = m_ui.pageSizeCombo->currentData().value(); // TODO Set layout margin min/max to printer custom min/max - m_pageLayout.setPageSize(QPageSize(id)); + m_pageLayout.setPageSize(pageSize); } else { QSizeF customSize; if (m_pageLayout.orientation() == QPageLayout::Landscape) diff --git a/src/printsupport/dialogs/qpagesetupdialog_unix_p.h b/src/printsupport/dialogs/qpagesetupdialog_unix_p.h index 574569de29..292cccd7ea 100644 --- a/src/printsupport/dialogs/qpagesetupdialog_unix_p.h +++ b/src/printsupport/dialogs/qpagesetupdialog_unix_p.h @@ -102,6 +102,7 @@ private: QPageLayout m_pageLayout; QPageLayout::Unit m_units; bool m_blockSignals; + int m_realCustomPageSizeIndex; }; QT_END_NAMESPACE -- 2.15.1
