Useful Thoughts and Actions Taken

LibUSB

USB on Linux

• Dreamin in Code: LibUSB-1.0 on Linux
• Doxygen of LibUSB-1.0 

[insert page='gnu-build-system-autotools-table-of-contents-toc' display='content']

Qt widget libraries are now semi proprietary. Again I ask now? What if someone forked the project before the buyout?

Qt library packages

Qt installation on Windows

• Qt4 tutorial for absolute beginners
• How to install Qt on windows: 20 steps
• Qt in NetBeans IDE – Step by Step HelloForm.zip

Qt in IDE

• Mini How-to: Qt on NetBeans
• Qt in NetBeans IDE – Step by Step  – this is a windows based instructional  HelloForm.zip
• NetBeans with Qt running on linux – how to get a helloworld like program running
• Qt & NetBeans on Linux: Install and Test
• Installed Qt Creator by downloading the linux 32 bit bin package – I had tried installing from apt-get and using synaptic – both said they depended on Qt5 level stuff and I did not want to risk breaking my Qt4 level libraries needed for QUCS

End Application Notes

• QTableView – a grid view that can be used with database etc.
• Serial Port under QT

Shared Object / DLL

    Linux

• Shared Libraries with GCC on Linux  – Very simple example how to use .SO and the associated necessary steps to set the library path.  Uses ldconfig to set the library pathes.
• Linux Dynamic binding – .SO unknown to .exe before run time – a method for plugins   
• Call Symbol From Shared Object File (DLL) with QLibrary
• Creating and using shared libraries in Linux

    Windows

• Building and using DLL's with Cygwin
• Create a dll for windows using GCC
• Windows example of dynamic binding

    CrossPlatform

• Echo plugin example
• Plug and Paint – Qt plugin example with dynamic linking
• How to write Qt PlugIns
• Writing plugins with C/C++ shared libraries – has information on how to keep things compatible between Linux and Windows
• Plugins in C
• Code Project: Win32/Linux dynamic library loader class – has example cross platform example

Additional Notes

• Adding / Installing packages from CD
• A simple introduction to Qt platform abstraction
• App does not run when outside of qt creator

Qt Tutorials

• Qt reference documentation  – exhaustive 1 stop shop with many examples
• C++ GUI Programming with Qt3  ( Jasmin Blanchette / Mark Summerfield )   Example source code from C++ GUI Programming with Qt3
• C++ GUI Programming with Qt4 (Jasmin Blanchette / Mark Summerfield )     Download the book examples for Windows (Zipped)    Download the book examples for Linux/UNIX (tarred and gzipped)  Book Page
• Qt SpreadSheet chapter 5 Qt4 book example project built and ran under Qt Creator with library 4.8.4 – under windows
• Qt spreadsheet using Qt4 libraries having output files in orderly subdirectories   – How to specify different Debug/Release output directories in QMake .pro file : The first answer entry did not work.  Probably because "release" was capitalized
• Qt3 to Qt4 migration using QucsEdit in stand alone mode  Learn about the Qt classes and I18n of Qt as a side effect.
•  Qt Internationalized I18n Hello World Example Demo Project

 These are command line built examples where you dial into the directory with the files then

• qmake -project     generates the .pro project file
• qmake      generates the makefile for the gcc compiler.  Statements invoking the MOC meta object compiler  are added to the make file.  
• make     does what a standard make step does using the Makefile.  Includes the MOC invocations.  Generates:   moc_FileName  FileName.o   links and makes the executable

Running QUCS

• Many QUCS simulation examples – this appears dead as of 5/2/13 > local example archive   Local Example page 
• QUCS WorkBook  – In depth demonstration of all features

OverView

• QUCS simulation facility
• QUCS overview presentation
• Overview of QUCS circuit analysis mathematics – in depth study is warranted for the IC Design career goal.

Developing QUCS

• QUCS Build Instructions
• Doxygen mapping of QUCS
• QUCS appears to use the GNU Build System
• My QUCS Build Notes   – This has been moved to its own page due to size

 

QUCSstudio

• OverView of purpose pdf
• QUCSstudio –  QucsStudio is mainly a circuit simulator that has evolved out of the project Qucs, but isn't compatible with it. It's meant be be a test project to create a complete development environment for electrical engineers. (graphical user interface with circuit simulator, PCB layouting, numerical data processing etc.) The application uses the free port Q…/Free of the graphical user interface Qt® by Trolltech®. 

QUCS Chatter

• Email archive – as of 1/9/13 there is activity focusing on port to Qt4
