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.
