[quote author="Eddy" date="1323889356"]I recently installed qwt 6.0.1 and there is no need to get it for using qwt anymore[/quote]
Since the MathML package became unmaintained I have stripped it down ( Qwt is interested in the renderer only not the widget ) added a couple of minor patches and committed it to the Qwt repository.
Because this code has a different license as Qwt itsself it is built as extra library ( qwtmathml ). Of course this library is optional and as most users don't use it, it will always be an optional part only.
and append readBytes to a QString until I reach my message delimiter. At the moment, I'm testing my code with a virtual serial port connecting 2 x VirtualBox's using the following for these serial port settings:
And if you're using OS Windows and QtSDK, then you have an build error qwineventnotifier_p.h.
The solution below:
It private file is located in the source code Qt4:
But since is a private class, then it does not include in the Qt SDK.
Therefore, in two ways:
Or build Qt4 from source and use.
Or take this header file from the Qt4 source and copy it to the Qt SDK, example to:
Where instead 4.7.4. may be your current version (eg 4.8.0),
and instead msvc2008 may be mingw.
Sounds like a problem in Qwt to me, to be honest. I think what you were doing in the constructor should work. The only thing I can think about, is that perhaps (speculation) Qwt does not accept setting up axis before you actually told it about the kind of data is need to plot (and what axis there are in that)?
Yes, the Qt libs are precompiled. To use boost together with those you will have to compile it with the same settings. It will not help to change 10.5 to 10.7 in the mkspecs, as Qt is still built with the old settings!
You have two options here:
build boost with the same settings as Qt
build Qt manually with the same settings as you build boost
I personally would go with the first option and rebuild Qt.
Good question. I guess this is tricky to do with the standard Qt slider widget. What you might considder (if possible for you), is to use Qwt instead. It provides more options for its slider widget, including having custom scales. It even supports logartitmic scales.
You are, unfortunately, very right. This library of mine is still very static and the redesign is slow-going (work responsibilities are picking up towards the end of the year). With regards to interaction, have a look at the Qt Chart example if you haven't done so yet:
im also a real beginner and i wanna know if there's any clear advice about how to use the qserialdevice library in a project?
i cant compile the examples i guess i have to build the buildlibrary first but the problem is that i get errors inside the codes and so building the library doesnt get successful and when building the examples,i get this error : cannot find -lqserialdevice
how shuold i correctly build the library so that i can compile examples of qserialdevice and also use the library?
is there a step by step guide for that or can anybody plz tell me in detail?
ill be so thankfull for that.
