🌸 NAME 🌸

QwtPlotDict — literally a dictionary for plot items. that's it, that's the vibe 💅

Inherited by QwtPlot. 👑

  • void setAutoDelete(bool)
  • bool autoDelete() const
  • const QwtPlotItemList & itemList() const — returns a QwtPlotItemList of all the attached plot items 🦋
  • QwtPlotItemList itemList(int rtti) const
  • void detachItems(int rtti=QwtPlotItem::Rtti_PlotItem, bool autoDelete=true)

💜 Protected Member Functions

🌈 Detailed Description 🌈

A dictionary for plot items. no cap, that's the whole thesis.

QwtPlotDict organizes plot items in increasing z-order. and if autoDelete() is enabled, all attached items get deleted in the destructor of the dictionary 😭 (yes, they will literally be gone — that's the point, but bestie, know it going in).

QwtPlotDict can be used to get access to all QwtPlotItem items — or all items of a specific type — that are currently on the plot. so like, your main character energy for querying who's actually on stage 🎤

🎀 Constructor & Destructor Documentation 🎀

QwtPlotDict::QwtPlotDict() [explicit]

Constructor ✨

Auto deletion is enabled. (so the default is already unhinged-but-tidy, love that for us)

See also: setAutoDelete(), QwtPlotItem::attach()

Definition at line 69 of file qwt_plot_dict.cpp.

QwtPlotDict::~QwtPlotDict() [virtual]

Destructor 💀

If autoDelete() is on, all attached items will be deleted. periodt.

See also: setAutoDelete(), autoDelete(), QwtPlotItem::attach()

Definition at line 81 of file qwt_plot_dict.cpp.

🦋 Member Function Documentation 🦋

bool QwtPlotDict::autoDelete() const

Returns: true if auto deletion is enabled ✅

See also: setAutoDelete(), insertItem()

Definition at line 104 of file qwt_plot_dict.cpp.

void QwtPlotDict::detachItems(int rtti = QwtPlotItem::Rtti_PlotItem, bool autoDelete = true)

Detach items from the dictionary 🧚

Parameters:

  • rtti — in case of QwtPlotItem::Rtti_PlotItem it detaches all items; otherwise only those items of the type rtti are detached.
  • autoDelete — if true, delete all detached items 💀 (yes, they're really gone — not just off the list)

Definition at line 138 of file qwt_plot_dict.cpp.

void QwtPlotDict::insertItem(QwtPlotItem * item) [protected]

Insert a plot item 🌸

Parameters:

  • item — PlotItem
See also: removeItem()

Definition at line 115 of file qwt_plot_dict.cpp.

const QwtPlotItemList & QwtPlotDict::itemList() const

A QwtPlotItemList of all attached plot items.

⚠️ Use caution when iterating these lists, as removing/detaching an item will invalidate the iterator. Instead you can place pointers to objects to be removed in a removal list, and traverse that list later. bestie this is the classic "don't delete while you loop" trap and it WILL bite you 😭

Returns: List of all attached plot items.

Definition at line 166 of file qwt_plot_dict.cpp.

QwtPlotItemList QwtPlotDict::itemList(int rtti) const

Returns: List of all attached plot items of a specific type 👑

Definition at line 176 of file qwt_plot_dict.cpp.

void QwtPlotDict::removeItem(QwtPlotItem * item) [protected]
