Re: [Interest] Receiving audio through USB frame grabber and playing it

SampleType defines how each sample is represented, the min and max value. For instance, in my audio applications, I use floating point sample type because I wan’t to generate samples between -1 and 1. Working with a normalised value is a very convenient way of making calculations, but on some

Re: [Interest] Receiving audio through USB frame grabber and playing it

Thanks for the response and apologies for my error. This morning I discovered that I was able to hear on 24 bit samples but not on 16 bit sample because I hadn't raised volume to its maximum. Now, with 16 bit samples I am able to hear the "buzzing sound". Nothing more than that. Now the settings

Re: [Interest] Receiving audio through USB frame grabber and playing it

Have you considered converting manually between 16 and 24 bit samplesizes? Obviously you pass the wrong sample size to the output, and that one takes data as is as this is just a byte stream. That is why you need to check that either the formats are compatible or do a conversion. This is nothing

Re: [Interest] item edit on mouse over - was: dynamic widget creation in QScrollArea

So it appears the solution is to have the delegate emit it's closeEditor signal as shown below as well as have the view explicitly close the current editor before opening a new one. I hope there are no side effects to this but we will see... On 12/08/16 2:27 PM, Frank Rueter | OHUfx wrote: Qu

Re: [Interest] item edit on mouse over - was: dynamic widget creation in QScrollArea

Quick follow up (as usual): The problem is that the view's mouseMoveEvent fires faster than the MyMovie() widget's leaveEvent can trigger the emission of the closeEditor signal. In other words I have to somehow refactor the code to ensure that the current editor is closed before the new one is

Re: [Interest] item edit on mouse over - was: dynamic widget creation in QScrollArea

So I made some progress here: I am now using the QListView's mouseMoveEvent() to get the item under the mouse and edit() it: def mouseMoveEvent(self, event): '''Find item under mouse and pop it into edit mode''' index = self.indexAt(event.pos()) if index.isValid():

Re: [Interest] best qt class to use to detect line/polygon/region collision

The sweepline algorithm finds all intersection points in a set of lines and (IIRC) it has running time O(n*log(n)). I doubt that it is possible to do faster than that... Note: there are several different algorithms referred to as "sweepline algorithm". The sweepline is more of a general approach th

I think qmlimportscanner only scan QML file within the project directory regardless of is it used / referred by .pro or resource file. All QML files in sibling directory will be ignored. I have got similar problem. So far I fix it by adding extra import statement in the main.qml . And leave a comm
