Methods

MethodDescription
virtual System::SharedPtr<ITextFrame> AddTextFrameForOverriding(System::String)Initialize TextFrameForOverriding with the text in paramener "text". If TextFrameForOverriding is already initialized then simply changes its text.
virtual bool Equals(ptr)Compares objects using C# Object.Equals semantics.
static std::enable_if<IsSmartPtr<T1>::value&&IsSmartPtr<T2>::value, bool>::type Equals(T1 const&, T2 const&)Compares reference type objects in C# style.
static std::enable_if<!IsSmartPtr<T1>::value&&!IsSmartPtr<T2>::value, bool>::type Equals(T1 const&, T2 const&)Compares value type objects in C# style.
static bool Equals(float const&, float const&)Emulates C#-style floating point comparison where two NaNs are considered equal even though according to IEC 60559:1989 NaN is not equal to any value, including NaN.
static bool Equals(double const&, double const&)Emulates C#-style floating point comparison where two NaNs are considered equal even though according to IEC 60559:1989 NaN is not equal to any value, including NaN.
virtual bool FastCast(const Details::FastRttiBase&, void **) constFor internal purposes only.
virtual float get_ActualHeight()Specifies actual height of the chart element. Call method IChart::ValidateChartLayout before to get actual values. Read float.
virtual float get_ActualWidth()Specifies actual width of the chart element. Call method IChart::ValidateChartLayout before to get actual values. Read float.
virtual float get_ActualX()Specifies actual x location (left) of the chart element relative to the left top corner of the chart. Call method IChart::ValidateChartLayout before to get actual values. Read float.
virtual float get_ActualY()Specifies actual top of the chart element relative to the left top corner of the chart. Call method IChart::ValidateChartLayout before to get actual values. Read float.
virtual float get_Bottom()Gets the top of the chart element as a fraction of the height of the chart. Read-only float.
virtual System::SharedPtr<IChart> get_Chart()Returns the chart. Read-only IChart.
virtual System::SharedPtr<IDataLabelFormat> get_DataLabelFormat()Returns format of the data label. Read-only IDataLabelFormat.
virtual float get_Height()Specifies the height of the chart element as a fraction of the height of the chart. Read float.
virtual bool get_IsVisible()False means that data label is not visible (and so all Show*-flags (ShowValue, …) are false). Read-only bool.
virtual System::SharedPtr<IPresentation> get_Presentation()Returns the presentation. Read-only IPresentation.
virtual float get_Right()Gets the right of the chart element as a fraction of the width of the chart. Read-only float.
virtual System::SharedPtr<IBaseSlide> get_Slide()Returns the base slide. Read-only IBaseSlide.
virtual System::SharedPtr<IChartTextFormat> get_TextFormat()Returns chart text format. Read-only IChartTextFormat.
virtual System::SharedPtr<ITextFrame> get_TextFrameForOverriding()Can contain a rich formatted text. If this property is not null then this formatted text value overrides auto-generated text. Auto-generated text is an implicit property of the data label, the display unit label of the value axis, the axis title, the chart title, the label of the trendline. Auto-generated text is formatted with the IFormattedTextContainer::get_TextFormat property. Read-only ITextFrame.
virtual System::SharedPtr<IChartDataCell> get_ValueFromCell()Gets workbook data cell. Applied if IDataLabelFormat::get(set)_ShowLabelValueFromCell property equals true.
virtual float get_Width()Specifies the width of the chart element as a fraction of the width of the chart. Read float.
virtual float get_X()Specifies the x location (left) of the chart element as a fraction of the width of the chart. Read float.
virtual float get_Y()Specifies the top of the chart element as a fraction of the height of the chart. Read float.
virtual System::String GetActualLabelText()Returns actual label text based on DataLabelFormat settings or TextFrameForOverriding.Text value.
Detail::SmartPtrCounter * GetCounter()Gets reference counter data structure associated with the object.
virtual int32_t GetHashCode() constAnalog of C# Object.GetHashCode() method. Enables hashing of custom objects.
virtual const TypeInfo& GetType() constGets actual type of object. Analog of C# System.Object.GetType() call.
virtual void Hide()Make data label hidden by setting all Show*-flags (ShowValue, …) to false state. IsVisible will be false after this.
virtual bool Is(const TypeInfo&) constCheck if object represents an instance of type described by targetType. Analog of C# ‘is’ operator.
void Lock()Implements C# lock() statement locking. Call directly or use LockContext sentry object.
virtual ptr MemberwiseClone() constAnalog of C# Object.MemberwiseClone() method. Enables cloning custom types.
Object()Creates object. Initializes all internal data structures.
Object(Object const&)Copy constructor. Doesn’t copy anything, really, just initializes new object and enables copy constructing subclasses.
Object& operator=(Object const&)Assignment operator. Doesn’t copy anything, really, just initializes new object and enables copy constructing subclasses.
static bool ReferenceEquals(ptr const&, ptr const&)Compares objects by reference.
static std::enable_if<!IsSmartPtr<T>::value, bool>::type ReferenceEquals(T const&, T const&)Compares objects by reference.
static std::enable_if<!IsSmartPtr<T>::value, bool>::type ReferenceEquals(T const&, std::nullptr_t)Reference-compares value type object with nullptr.
bool ReferenceEquals(String const&, std::nullptr_t)Specialization of Object::ReferenceEquals for case of string and nullptr.
bool ReferenceEquals(String const&, String const&)Specialization of Object::ReferenceEquals for case of strings.
int RemovedSharedRefs(int)Decreases shared reference count by specified value.
virtual void set_Height(float)Specifies the height of the chart element as a fraction of the height of the chart. Write float.
virtual void set_ValueFromCell(System::SharedPtr<IChartDataCell>)Sets workbook data cell. Applied if IDataLabelFormat::get(set)_ShowLabelValueFromCell property equals true.
virtual void set_Width(float)Specifies the width of the chart element as a fraction of the width of the chart. Write float.
virtual void set_X(float)Specifies the x location (left) of the chart element as a fraction of the width of the chart. Write float.
virtual void set_Y(float)Specifies the top of the chart element as a fraction of the height of the chart. Write float.
virtual void SetTemplateWeakPtr(uint32_t)Set n’th template argument a weak pointer (rather than shared). Allows switching pointers in containers to weak mode.
int SharedCount() constGets current value of shared reference counter.
Object * SharedRefAdded()Increments shared reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector.
int SharedRefRemovedSafe()Decrements and returns shared reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector.
virtual String ToString() constAnalog of C# Object.ToString() method. Enables converting custom objects to string.
static const TypeInfo& Type()Implements C# typeof(System.Object) construct.
void Unlock()Implements C# lock() statement unlocking. Call directly or use LockContext sentry object.
Detail::SmartPtrCounter * WeakRefAdded()Increments weak reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector.
void WeakRefRemoved()Decrements weak reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector.
virtual ~Object()Destroys object. Frees all internal data structures.
