qt plus

qt-plus

Utility classes extending Qt's functionnality.

Building

• Open /qt-plus.pro in QtCreator
• Build

How to use

• As any other qt library or
• Embed in app by including (in the .pro) one of:
  • qt-plus-nolib-basic.pri (to use basic functionalities)
  • qt-plus-nolib-web.pri (to use web classes)
  • qt-plus-nolib-qml.pri (to use qml parsing and analyzing classes)

Classes

The full documentation for classes is available after project build, in the help directory.

Note: Due to qdoc changes in Qt 5.12 (i think), the help files do not compile if using a recent Qt Creator version. This issue is being fixed. Help may still be viewed in the related cpp file.

QTree

Template for a tree structure. Each node has a value and 0 or more child nodes.
May be used in a model where a variable can hold a scalar, a list or a tree.

CSingleton

A template for singleton objects, based on the Singleton design pattern.

CFactory

A template for a factory of objects, based on the Factory design pattern.

CXMLNode

A helper class that wraps the XML and JSON facilities of Qt. Makes DOM style documents easier to use.

Attention : This class is really slow with very large documents because a lot of nodes are created and copied around...

CLogger

A simple yet efficient logger.

CImageUtilities

A singleton that provides helpful image processing functions. Can do the following:

• Apply a filter matrix to a QImage
• Select pixels in a QImage by tint, resulting in a grayscale mask image
• Modify the HSV values of a QImage, using a QImage mask for pixel selection
• Colorize a QImage, using a QImage mask for pixel selection
• Split RGBA channels of a QImage
• Merge RGBA channels of several QImages
• Split HSVA channels of a QImage
• Merge HSVA channels of several QImages
• Find the dominant hue of a QImage
• Find the dominant luminance (value) of a QImage
• Compute the disparity map (depth) from two QImages (left and right eye)

CImageHistogram

A class that contains the histogram of a QImage.

CLargeMatrix

A class that can hold an NxN matrix. Used, among other things, for image filtering.

CTextGenerator

A class that generates random words, sentences, paragraphs, pages using random syllables. Translated to C++ from the Javascript class 'fake-words'. Original work is Copyright (c) anticoders: https://github.com/anticoders/fake-words

QMLTreeContext

A full QML parser.
Holds the contents of a QML file in the form of a tree, made of specialized classes for each kind of QML and JS declarations.

• Can recreate the original QML file from the statement tree.
• Can convert the statement tree to XML.
• Has a known parsing problem : when using a prefix operator (like ++a)

QMLAnalyzer

A class that allows static analysis of a QML statement tree (parsed using QMLTreeContext).
Uses a grammar file in XML format that declares what to check and eventually reject.

CSecureContext

A class that allows easy secure data exchange between servers and client of any kind. Based on RSA (copyright Nedim Srndic) and ROKE, a home made symetric encryption algorithm.

CHTTPServer

Implements the base functionalities (GET and POST) of an HTTP server (see RFC 7230).
Can do the following:

• Handles GET and POST requests (maybe more in the future)
• Serve local file ressources
• Define the accessible folders for ressources
• Generate dynamic HTML content via overridden methods.
• More or less efficient flood protection (has not been tested on large scale)
• No https for now

CDynamicHTTPServer

Implements the base functionalities of a web server that generates dynamic HTML content. A subclass of CDynamicHTTPServer may generate content in two ways:

• Using a CWebComposer to generate HTML tags in a string
• Using a CWebFactory to generate a CWebPage, which is a container of CWebControls

The second method works like ASP, with a view state that enables to transfer a serialized, compressed and eventually crypted (when someone wants to code it) version of the CWebPage between server and client. This method enables See the documentation of CWebPage for more information.

CRemoteControl

A server/client that acts somewhat like SSH on Linux. Enables remote file transfers and remote shell.

CMJPEGClient

A client for MJPEG streams. Notifies via signal whenever a new image arrives.

CMJPEGServer

A server that creates an MJPEG stream for clients, based on CHTTPServer.

CTDMADevice

A class that mimics the TDMA concept. But instead of devices auto-synchronizing themselves, a master device does it.
Can be used to transfer data from master <-> slave on a network with a single data channel.
Inherits QIODevice and uses a QIODevice instance for input and output.

CPIDController

A PID (Proportional Integral Derivative) controller for autopilots or mechanical controls.

CAverager

A template used to average values.

CGeoUtilities

Contains methods to convert from geo coordinates (latitude, longitude, altitude) to cartesian coordinates (x, y, z) and back.

QML files

ScatteredItemView.qml

This view shows a wireframe of a QML scene. It can be rotated and zoomed. Elements can be isolated.
