| - | The [[Qt:Документация 4.3.2/qapplication | QApplication]] class has been split into two classes: [[Qt:Документация 4.3.2/qcoreapplication | QCoreApplication]] and [[Qt:Документация 4.3.2/qapplication | QApplication]]. The new [[Qt:Документация 4.3.2/qapplication | QApplication]] class inherits [[Qt:Документация 4.3.2/qcoreapplication | QCoreApplication]] and adds GUI-related functionality. In practice, this has no consequences for existing Qt applications.

| | + | На данный момент здесь затронуты такие библиотеки и языки программирования как: |
| | + | <div style="float:left; width:49%;"> |
| | | | |
| - | In addition, the following API changes were made:

| - | <li>[[Qt:Документация 4.3.2/qapplication#allWidgets | QApplication::allWidgets]]() and [[Qt:Документация 4.3.2/qapplication#topLevelWidgets | QApplication::topLevelWidgets]]() used to return a pointer to a [[Qt:Документация 4.3.2/qwidget#QWidgetList-typedef | QWidgetList]]. Now they return a [[Qt:Документация 4.3.2/qwidget#QWidgetList-typedef | QWidgetList]].<br />Also, [[Qt:Документация 4.3.2/qwidget#QWidgetList-typedef | QWidgetList]] has changed from being a typedef for QPtrList<[[Qt:Документация 4.3.2/qwidget | QWidget]]> to being a typedef for [[Qt:Документация 4.3.2/qlist | QList]]<[[Qt:Документация 4.3.2/qwidget | QWidget]] *>. See the [[#qwidgetlist-section | section on QWidgetList]] below for details.<br /><br />For example, if you have code like
| + | |colortitle = #cef3ce |
| - | <source lang="cpp-qt">
| + | |colorborder = #a3bfb1 |
| - | QWidgetList *list = QApplication::topLevelWidgets();
| + | |colorback = #f5fffa |
| - | QWidgetListIt it(*list);
| + | }} |
| - | QWidget *widget;
| + | |
| - | while ((widget = it.current())) {
| + | </div> |
| - | if (widget->inherits("MainWindow"))
| + | |
| - | ((MainWindow *)widget)->updateRecentFileItems();
| + | <div style="float:right; width:49%"> |
| - | ++it;
| + | |
| - | }
| + | {{Блок раздела |
| - | delete list;
| + | |title = Языки программирования |
| - | </source> | + | |colortitle = #cecef3 |
| - | you can rewrite it as
| + | |colorborder = #a3b0bf |
| - | <source lang="cpp-qt"> | + | |colorback = #f5faff |
| - | QWidgetList list = QApplication::topLevelWidgets();
| + | }} |
| - | for (int i = 0; i < list.size(); ++i) {
| + | |
| - | if (MainWindow *mainWin = qobject_cast<MainWindow>(list.at(i)))
| + | </div> |
| - | mainWin->updateRecentFileItems();
| + | __NOTOC__ __NOEDITSECTION__ |

| + | |
| - | </source></li>
| + | |
| - | <li>[[Qt:Документация 4.3.2/qapplication-qt3#setMainWidget | QApplication::setMainWidget]]() is no longer used. When all an application's windows are closed, the application will exit normally.</li>
