QT5.1标准对话框按钮显示英文问题解决办法
|
** QT5.1标准对话框按钮显示英文** QT标准对话框默认全是英文，需要在Qt安装目录下的translations，找到qt_zh_CN.qm和qt_zh_CN.ts。 直接用qt_zh_CN.qm，将其拷贝到工程目录，代码里根据路径调用： QDir dir(strPath + strUiLang); dir.setFilter(QDir::Files | QDir::Hidden | QDir::NoSymLinks | QDir::NoDotAndDotDot); dir.setNameFilters(QStringList()vecCurLang.clear(); //========================== for (int i = 0; i load(list[i].absoluteFilePath())) { vecCurLang.append(ptTranslator); qApp->installTranslator(ptTranslator.data()); } }但是，笔者，已经完成以上安装翻译文件，对于标准对话框的标准按钮，仍然显示英文，如QMessageBox里的显示yes,no；为何呢，对于qt4.8同样操作显示是中文，对于qt5.10为啥不翻译呢！ 强烈的好奇心促使笔者一查到底： Qt4.8源码： 标准对话框的按钮均来源于 QDialogButtonBox *buttonBox; 文字显示使用的是： buttonText = standardButtonText(sbutton); const char *QDialogButtonBoxPrivate::standardButtonText(QDialogButtonBox::StandardButton sbutton) const { const char *buttonText = 0; bool gnomeLayout = (layoutPolicy == QDialogButtonBox::GnomeLayout); switch (sbutton) { case QDialogButtonBox::Ok: buttonText = gnomeLayout ? QT_TRANSLATE_NOOP("QDialogButtonBox", "&OK") : QT_TRANSLATE_NOOP("QDialogButtonBox", "OK"); break; case QDialogButtonBox::Save: buttonText = gnomeLayout ? QT_TRANSLATE_NOOP("QDialogButtonBox", "&Save") : QT_TRANSLATE_NOOP("QDialogButtonBox", "Save"); break; case QDialogButtonBox::Open: buttonText = QT_TRANSLATE_NOOP("QDialogButtonBox", "Open"); break; case QDialogButtonBox::Cancel: buttonText = gnomeLayout ? QT_TRANSLATE_NOOP("QDialogButtonBox", "&Cancel") : QT_TRANSLATE_NOOP("QDialogButtonBox", "Cancel"); break; case QDialogButtonBox::Close: buttonText = gnomeLayout ? QT_TRANSLATE_NOOP("QDialogButtonBox", "&Close") : QT_TRANSLATE_NOOP("QDialogButtonBox", "Close"); break; case QDialogButtonBox::Apply: buttonText = QT_TRANSLATE_NOOP("QDialogButtonBox", "Apply"); break; case QDialogButtonBox::Reset: buttonText = QT_TRANSLATE_NOOP("QDialogButtonBox", "Reset"); break; case QDialogButtonBox::Help: buttonText = QT_TRANSLATE_NOOP("QDialogButtonBox", "Help"); break; case QDialogButtonBox::Discard: if (layoutPolicy == QDialogButtonBox::MacLayout) buttonText = QT_TRANSLATE_NOOP("QDialogButtonBox", "Don't Save"); else if (layoutPolicy == QDialogButtonBox::GnomeLayout) buttonText = QT_TRANSLATE_NOOP("QDialogButtonBox", "Close without Saving"); else buttonText = QT_TRANSLATE_NOOP("QDialogButtonBox", "Discard"); break; case QDialogButtonBox::Yes: buttonText = QT_TRANSLATE_NOOP("QDialogButtonBox", "&Yes"); break; case QDialogButtonBox::YesToAll: buttonText = QT_TRANSLATE_NOOP("QDialogButtonBox", "Yes to &All"); break; case QDialogButtonBox::No: buttonText = QT_TRANSLATE_NOOP("QDialogButtonBox", "&No"); break; case QDialogButtonBox::NoToAll: buttonText = QT_TRANSLATE_NOOP("QDialogButtonBox", "N&o to All"); break; case QDialogButtonBox::SaveAll: buttonText = QT_TRANSLATE_NOOP("QDialogButtonBox", "Save All"); break; case QDialogButtonBox::Abort: buttonText = QT_TRANSLATE_NOOP("QDialogButtonBox", "Abort"); break; case QDialogButtonBox::Retry: buttonText = QT_TRANSLATE_NOOP("QDialogButtonBox", "Retry"); break; case QDialogButtonBox::Ignore: buttonText = QT_TRANSLATE_NOOP("QDialogButtonBox", "Ignore"); break; case QDialogButtonBox::RestoreDefaults: buttonText = QT_TRANSLATE_NOOP("QDialogButtonBox", "Restore Defaults"); break; case QDialogButtonBox::NoButton: ; } // switch return buttonText; }打开qt_zh_CN.ts文件，里面有QDialogButtonBox的翻译部分，当然显示中文； Qt5.10 同样的标准对话框按钮仍然使用QDialogButtonBox，但是源码部分，对于按钮的text显示进行了修改： QPushButton *button = new QPushButton(QGuiApplicationPrivate::platformTheme()->standardButtonText(sbutton), q); ```cpp QString QPlatformTheme::standardButtonText(int button) const { return QPlatformTheme::defaultStandardButtonText(button); } //============= QString QPlatformTheme::defaultStandardButtonText(int button) { switch (button) { case QPlatformDialogHelper::Ok: return QCoreApplication::translate("QPlatformTheme", "OK"); case QPlatformDialogHelper::Save: return QCoreApplication::translate("QPlatformTheme", "Save"); case QPlatformDialogHelper::SaveAll: return QCoreApplication::translate("QPlatformTheme", "Save All"); case QPlatformDialogHelper::Open: return QCoreApplication::translate("QPlatformTheme", "Open"); case QPlatformDialogHelper::Yes: return QCoreApplication::translate("QPlatformTheme", "&Yes"); case QPlatformDialogHelper::YesToAll: return QCoreApplication::translate("QPlatformTheme", "Yes to &All"); case QPlatformDialogHelper::No: return QCoreApplication::translate("QPlatformTheme", "&No"); case QPlatformDialogHelper::NoToAll: return QCoreApplication::translate("QPlatformTheme", "N&o to All"); case QPlatformDialogHelper::Abort: return QCoreApplication::translate("QPlatformTheme", "Abort"); case QPlatformDialogHelper::Retry: return QCoreApplication::translate("QPlatformTheme", "Retry"); case QPlatformDialogHelper::Ignore: return QCoreApplication::translate("QPlatformTheme", "Ignore"); case QPlatformDialogHelper::Close: return QCoreApplication::translate("QPlatformTheme", "Close"); case QPlatformDialogHelper::Cancel: return QCoreApplication::translate("QPlatformTheme", "Cancel"); case QPlatformDialogHelper::Discard: return QCoreApplication::translate("QPlatformTheme", "Discard"); case QPlatformDialogHelper::Help: return QCoreApplication::translate("QPlatformTheme", "Help"); case QPlatformDialogHelper::Apply: return QCoreApplication::translate("QPlatformTheme", "Apply"); case QPlatformDialogHelper::Reset: return QCoreApplication::translate("QPlatformTheme", "Reset"); case QPlatformDialogHelper::RestoreDefaults: return QCoreApplication::translate("QPlatformTheme", "Restore Defaults"); default: break; } return QString(); }然而问题来了，5.10的qt_zh_CN.ts文件中并没有针对QPlatformTheme的翻译部分，所有导致5.10标准的对话框按钮仍显示为英文； 解决办法： 不修改qt源码，直接在自己的类中添加对QPlatformTheme的翻译，然后在自己的翻译文件qm中，翻译一遍标准按钮部分即可； void FrameWindow::Impl::RetranslateUi(FrameWindow* parent) { //标准对话框按钮翻译：qt_zh_CN.qm文件中没有 QCoreApplication::translate("QPlatformTheme", "OK"); QCoreApplication::translate("QPlatformTheme", "Save"); QCoreApplication::translate("QPlatformTheme", "Save All"); QCoreApplication::translate("QPlatformTheme", "Open"); QCoreApplication::translate("QPlatformTheme", "&Yes"); QCoreApplication::translate("QPlatformTheme", "Yes to &All"); QCoreApplication::translate("QPlatformTheme", "&No"); QCoreApplication::translate("QPlatformTheme", "N&o to All"); QCoreApplication::translate("QPlatformTheme", "Abort"); QCoreApplication::translate("QPlatformTheme", "Retry"); QCoreApplication::translate("QPlatformTheme", "Ignore"); QCoreApplication::translate("QPlatformTheme", "Close"); QCoreApplication::translate("QPlatformTheme", "Cancel"); QCoreApplication::translate("QPlatformTheme", "Discard"); QCoreApplication::translate("QPlatformTheme", "Help"); QCoreApplication::translate("QPlatformTheme", "Apply"); QCoreApplication::translate("QPlatformTheme", "Reset"); QCoreApplication::translate("QPlatformTheme", "Restore Defaults"); }更新ts文件，发布qm即可，英文变中文； 》》记录解决问题过程，方便自己，惠及他人！不足之处，欢迎指正！ |
