The following class members are part of the Qt 3 support layer. They are provided to help you port old code to Qt 4. We advise against using them in new code.
Use ColorSpec instead.
Use colorSpec() instead, and use ColorSpec as the enum type.
See also setColorMode().
Use flush() instead.
This feature does not exist anymore. This function always returns true in Qt 4.
Strips out vertical alignment flags and transforms an alignment align of Qt::AlignLeft into Qt::AlignLeft or Qt::AlignRight according to the language used.
Use QSysInfo::MacintoshVersion instead.
Returns the main application widget, or 0 if there is no main widget.
See also setMainWidget().
Use layoutDirection() instead.
See also setReverseLayout().
Use setColorSpec() instead, and pass a ColorSpec value instead.
See also colorMode().
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
Use the two-argument overload instead.
This function does nothing in Qt 4. The dummy parameter is ignored.
See also hasGlobalMouseTracking().
Sets the application's main widget to mainWidget.
In most respects the main widget is like any other widget, except that if it is closed, the application exits. Note that QApplication does not take ownership of the mainWidget, so if you create your main widget on the heap you must delete it yourself.
You need not have a main widget; connecting lastWindowClosed() to quit() is an alternative.
For X11, this function also resizes and moves the main widget according to the -geometry command-line option, so you should set the default geometry (using QWidget::setGeometry()) before calling setMainWidget().
See also mainWidget(), exec(), and quit().
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
Use changeOverrideCursor(cursor) (if replace is true) or setOverrideCursor(cursor) (if replace is false).
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
Use the two-argument overload instead.
Use setLayoutDirection() instead.
See also reverseLayout().
Use the palette instead.
For example, if you have code like
app.setWinStyleHighlightColor(color);
you can rewrite it as
QPalette palette(qApp->palette()); palette.setColor(QPalette::Highlight, color); qApp->setPalette(palette);
See also winStyleHighlightColor().
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
Use the two-argument widgetAt() overload to get the child widget. To get the top-level widget do this:
QWidget *widget = qApp->widgetAt(x, y); if (widget) widget = widget->window();
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
Use the single-argument widgetAt() overload to get the child widget. To get the top-level widget do this:
QWidget *widget = qApp->widgetAt(point); if (widget) widget = widget->window();
Use qApp->palette().color(QPalette::Active, QPalette::Highlight) instead.
See also setWinStyleHighlightColor().
Use QSysInfo::WindowsVersion instead.
Use CustomColor instead.
Use NormalColor instead.
