typedef QApplication:: ColorMode

使用 ColorSpec 代替。

成員函數文檔編製

[static] ColorMode QApplication:: colorMode ()

使用 colorSpec () instead, and use ColorSpec as the enum type.

另請參閱 setColorMode ().

[static] void QApplication:: flushX ()

使用 flush () 代替。

[static] bool QApplication:: hasGlobalMouseTracking ()

This feature does not exist anymore. This function always returns true in Qt 4.

[static] Qt::MacintoshVersion QApplication:: macVersion ()

使用 QSysInfo::MacintoshVersion 代替。

[static] QWidget * QApplication:: mainWidget ()

Returns the main application widget, or 0 if there is no main widget.

另請參閱 setMainWidget ().

[static] bool QApplication:: reverseLayout ()

使用 layoutDirection () 代替。

另請參閱 setReverseLayout ().

[static] void QApplication:: setColorMode ( ColorMode mode )

使用 setColorSpec () instead, and pass a ColorSpec value instead.

另請參閱 colorMode ().

[static] void QApplication:: setFont (const QFont & font , bool b , const char * className = 0)

Use the two-argument overload instead.

[static] void QApplication:: setGlobalMouseTracking ( bool dummy )

This function does nothing in Qt 4. The dummy 參數被忽略。

另請參閱 hasGlobalMouseTracking ().

[static] void QApplication:: setMainWidget ( QWidget * mainWidget )

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. QApplication does not 擁有所有權對於 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 () 到 quit () is an alternative.

On 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().

另請參閱 mainWidget (), exec ()，和 quit ().

[static] void QApplication:: setOverrideCursor (const QCursor & cursor , bool replace )

使用 changeOverrideCursor ( cursor ) (if replace is true) or setOverrideCursor ( cursor ) (if replace 為 false)。

[static] void QApplication:: setPalette (const QPalette & pal , bool b , const char * className = 0)

Use the two-argument overload instead.

[static] void QApplication:: setReverseLayout ( bool reverse )

使用 setLayoutDirection () 代替。

另請參閱 reverseLayout ().

[static] void QApplication:: setWinStyleHighlightColor (const QColor & c )

Use the palette instead.

例如，若有代碼像

app.setWinStyleHighlightColor(color);
					

可以把它重寫成

QPalette palette(QApplication::palette());
palette.setColor(QPalette::Highlight, color);
QApplication::setPalette(palette);
					

另請參閱 winStyleHighlightColor ().

[static] QWidget * QApplication:: widgetAt ( int x , int y , bool child )

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();
					

[static] QWidget * QApplication:: widgetAt (const QPoint & point , bool child )

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();
					

[static] const QColor & QApplication:: winStyleHighlightColor ()

使用 QApplication::palette ().color( QPalette::Active , QPalette::Highlight ) 代替。

另請參閱 setWinStyleHighlightColor ().

[static] Qt::WindowsVersion QApplication:: winVersion ()

使用 QSysInfo::WindowsVersion 代替。

const int QApplication:: CustomColors

使用 CustomColor 代替。

const int QApplication:: NormalColors

使用 NormalColor 代替。
