This will also be the size of the image that the item is drawn - to, unless QQuickStyleItem::useNinePatchImage is set to false. In that - case, the size of the image will be set to the size of the item instead - (which is set from QML, and will typically be the same as the size of the control). - The default way to calculate minimumSize is to call style()->sizeFromContents() - with an empty content size. This is not always well supported by the legacy QStyle - implementations, which means that you might e.g get an empty size in return). - For those cases, the correct solution is to go into the specific platform style - and change it so that it returns a valid size also for this special case. - - 'implicitSize' should reflect the preferred size of the item, taking the - given content size (as set from QML) into account. But not all controls - have contents (slider), and for many controls, the content/label is instead - placed outside the item/background image (radiobutton). In both cases, the - size of the item will not include the content size, and implicitSize can - usually be set equal to minimumSize instead. - - 'contentRect' should be the free space where the contents can be placed. Note that - this rect doesn't need to have the same size as the contentSize provided as input - to the style item. Instead, QStyle can typically calculate a rect that is bigger, to - e.g center the contents inside the control. - - 'layoutRect' can be set to shift the position of the whole control so - that aligns correctly with the other controls. This is important for - controls that draws e.g shadows or focus rings. Such adornments should - be painted, but not be included when aligning the controls. - */ - - QSize minimumSize; - QSize implicitSize; - QRect contentRect; - QRect layoutRect; //If invalid, there are no layout margins! - QMargins ninePatchMargins; - qreal focusFrameRadius; -}; - -QDebug operator<<(QDebug debug, const StyleItemGeometry &cg); - -class QQuickStyleItem : public QQuickItem -{ - Q_OBJECT - - // Input - Q_PROPERTY(QQuickItem *control MEMBER m_control NOTIFY controlChanged) - Q_PROPERTY(qreal contentWidth READ contentWidth WRITE setContentWidth) - Q_PROPERTY(qreal contentHeight READ contentHeight WRITE setContentHeight) - Q_PROPERTY(bool useNinePatchImage MEMBER m_useNinePatchImage) - Q_PROPERTY(OverrideState overrideState MEMBER m_overrideState) - - // Output - Q_PROPERTY(QQuickStyleMargins contentPadding READ contentPadding() NOTIFY contentPaddingChanged) - Q_PROPERTY(QQuickStyleMargins layoutMargins READ layoutMargins() NOTIFY layoutMarginsChanged) - Q_PROPERTY(QSize minimumSize READ minimumSize() NOTIFY minimumSizeChanged) - Q_PROPERTY(int transitionDuration MEMBER m_transitionDuration CONSTANT) - - QML_NAMED_ELEMENT(StyleItem) - QML_UNCREATABLE("StyleItem is an abstract base class.") - -public: - enum DirtyFlag { - Nothing = 0, - Geometry, - Image, - Everything = 255 - }; - Q_DECLARE_FLAGS(DirtyFlags, DirtyFlag) - - enum OverrideState { - None = 0, - AlwaysHovered, - NeverHovered, - AlwaysSunken - }; - Q_ENUM(OverrideState) - - -#ifdef QT_DEBUG - enum DebugFlag { - NoDebug = 0x000, - Debug = 0x001, - Info = 0x002, - ImageRect = 0x004, - ContentRect = 0x008, - LayoutRect = 0x010, - Unscaled = 0x020, - InputContentSize = 0x040, - DontUseNinePatchImage = 0x080, - NinePatchMargins = 0x100, - SaveImage = 0x200, - }; - Q_FLAG(DebugFlag) - Q_DECLARE_FLAGS(DebugFlags, DebugFlag) -#endif - - explicit QQuickStyleItem(QQuickItem *parent = nullptr); - ~QQuickStyleItem() override; - - qreal contentWidth(); - void setContentWidth(qreal contentWidth); - qreal contentHeight(); - void setContentHeight(qreal contentHeight); - - QQuickStyleMargins contentPadding() const; - QQuickStyleMargins layoutMargins() const; - QSize minimumSize() const; - QSize imageSize() const; - qreal focusFrameRadius() const; - - Q_INVOKABLE virtual QFont styleFont(QQuickItem *control) const; - - void markGeometryDirty(); - void markImageDirty(); - -signals: - void controlChanged(); - void contentPaddingChanged(); - void layoutMarginsChanged(); - void fontChanged(); - void minimumSizeChanged(); - -protected: - void componentComplete() override; - QSGNode *updatePaintNode(QSGNode *oldNode, QQuickItem::UpdatePaintNodeData *updatePaintNodeData) override; - void geometryChange(const QRectF &newGeometry, const QRectF &oldGeometry) override; - void itemChange(ItemChange change, const ItemChangeData &data) override; - void updatePolish() override; - - virtual void connectToControl() const; - virtual void paintEvent(QPainter *painter) const = 0; - virtual StyleItemGeometry calculateGeometry() = 0; - - static QStyle::State controlSize(QQuickItem *item); - void initStyleOptionBase(QStyleOption &styleOption) const; - - inline QSize contentSize() const { return QSize(qCeil(m_contentSize.width()), qCeil(m_contentSize.height())); } - inline static QStyle *style() { return QQuickNativeStyle::style(); } - - template <class T> inline const T* control() const { -#ifdef QT_DEBUG - if (!dynamic_cast<T *>(m_control.data())) { - qmlWarning(this) << "control property is not of correct type"; - Q_UNREACHABLE(); - } -#endif - return static_cast<T *>(m_control.data()); - } - -#ifdef QT_DEBUG - DebugFlags m_debugFlags = NoDebug; -#endif - OverrideState m_overrideState = None; - -private: - inline void updateGeometry(); - inline void paintControlToImage(); - - int dprAlignedSize(const int size) const; - -#ifdef QT_DEBUG - void addDebugInfo(); -#endif - -private: - QPointer<QQuickItem> m_control; - QImage m_paintedImage; - StyleItemGeometry m_styleItemGeometry; - QSizeF m_contentSize; - - DirtyFlags m_dirty = Everything; - bool m_useNinePatchImage = true; - bool m_polishing = false; - mutable QQuickWindow *m_connectedWindow = nullptr; - -#ifdef Q_OS_MACOS - int m_transitionDuration = 150; -#else - int m_transitionDuration = 400; -#endif - -private: - friend class QtQuickControls2MacOSStylePlugin; -}; - -Q_DECLARE_OPERATORS_FOR_FLAGS(QQuickStyleItem::DirtyFlags) - -#ifdef QT_DEBUG -Q_DECLARE_OPERATORS_FOR_FLAGS(QQuickStyleItem::DebugFlags) -#endif - -QT_END_NAMESPACE - -QML_DECLARE_TYPE(QQuickStyleItem) - -#endif // QQUICKSTYLEITEM_H |
