Description:

This project is the result of writing a few applications by my small firm www.3electrons.com

Not all of the widgets work perfectly especially ScriptWidget and Chart widget.
But they are quite usable ;).

IMPORTANT NOTE
Because I decided to support my friend's son Kuba by this project, I liberalised this license with hope you are more likely to support Kuba by PayPal.
At the moment I am waiting for the charity organisation to create its own PayPal account and do all the paper work. So If you trust me you can donate Kuba by my PayPal account.
More details on my site:

Dear 3Electrons
chart has problem in QT 4.4.0 & VS2005
in scalegriddec... line 127 i--; in debug testing,channels size is one! no size checking.... also in paint event,i removed all call routine except (ChartDecorator::paint(painter,chart); unexpected error too

any question/additional info/effort

As I said this component is not perfect. I have never tested it against MsVisual. But, yes there was a bug, fortunetly extremly easy to fix. Please try last 218 version.

Dear 3E,same problem!
other widgets are good with nice UI for graph you need more effort.

i tried to find problem,but cant spend much time to find code.

 does not install

 
 by GoaSkin on: Nov 5 2008  
GoaSkinGoaSkin

On Mac OS X (version 10.4, QT version 4.4.3) the widget set compiles well but when typing 'make installs', the make command just goes into any subdirectory and says 'nothing to be done for...'

When I copy the designer plugin manually to the QT designer plugins folder, designing forms with the analog plugins works well. The uic generates a header file searching all the analog widgets in a project subdirectory.

 performance

Hi 3electrons,
I just want know one thing about your future widgets wich are describes on the last update.
Have you tried to test the graphicals performance? I.e the CPU load/usage when these widgets are in action. I ask that because these widgets are so beautiful, and I wonder if it will not penalize performance. thx in advance for the reply, and sorry if my english it isn't perfect :)

Yes I have tried it a little bit before with "oil widget" and few others. I have done it with ScriptWidget, which aim was to make widgets based on SVG and QtScript engines. Internal Java-Script API is very poor at the moment but performance is ok. However, making widget that is killing CPU is not a big problem. This is why I do consider to bring live to those "future" widgets by writing dedicated widgets in pure C++ where SVG themes could be exchanged, similar to potentiometer and counter widgets.
In my opinion it might be much simpler and more likely to make them alive, I am quite busy at my work at the moment.

Pure C++ widgets can be also better optimized by using cached and shared bitmaps, like it is done in WallClock, PotentioMeter and others. I still wonder if widgets with internal script engine is good idea. At least, how many people is going to use it that way?

I do believe I can achieve similar performance to PotentioMeter widget with C++ only approach.

P.S. Glad you like them ;).

By The way, your flags.pri file is filled with useless platform and CPU specific compiler settings including hardcoded paths.

MSVC 2005 is not supported at the moment, but with your help it could be :).
From your error report it seems that you have problem with compiling analogwidgets_plugin. It is that because there is no rule for MSVC2005 how to build plugin.

I guess you could modify wince* rule to make it work with MSVC 2005 in analogwidgets/plugins/plugins.pro.

If you succeed a small patch is warmly welcomed.

>By The way, your flags.pri file is filled with useless platform and CPU specific compiler settings including hardcoded paths.
Yes for MSVC 2005 it is completely useless.

Now AnalogWidgets is ready to be used with MS VC 2008. It can probably be forced to work with earlier versions of MS VC.

 QWT

What are the differences between this project and the library QWT?
Why not work together?

Well, there are personal reasons.It is much easier to control your own project that you can develop in any direction you like. It started as a research/(needed features) project and it is not as mature as QWT is. So I do not even try to compete with QWT or any other library or component you can find here. It is just yet another library that does some basic things.
