I have started using GNU radio and was following this YouTube tutorial series to get familiar with GRC.
While following along with the tutorials I noticed that I am missing many of the GUI widgets that the tutor was using, for example, the variable slider widget.
I realise that the blocks ultimately translate to some python code, and we could create our own widgets, but the issue is with missing default widgets.
It may be relevant to state here that the software was installed using the synaptic package manager following the instructions given here.
Is there a fix for this? Maybe some more packages available on Synaptic?
In your linked tutorial, I believe that wx widgets are used. These are deprecated and you should swap to a Qt gui top_block. To get the slider he used, you may stick to a WX GUI Slider or use a QT GUI Range block, depending on whether your flowgraph is in wx or qt

I have been trying my hands for POC on an idea and trying to find languages which can support Mobile app development (Android/IOS) via single source code.
I zeroed on React-Native and Flutter.
What I found that for React-Native you still have to write code which is platform specific. Components need to be written differently for IOS and Android.
Then I looked in FLutter and I found that - "Flutter's widgets, however, while there are more of them, aren't really adaptive".
I am not able to understand it and what it means.
It would be really helpful if someone can help me with example or guide me to good reference.
In Flutter you have different sets of Widget Collection:
Material Widgets: Android-style
Cupertino Widgets: iOS-style
And lots of Widgets which aren't bound to one of those styles.
With this you are able to create a application looking like any style on any of the available platform. Therefore you can also have iOS-style Widgets on Android and vice versa.
If you want to have iOS Widgets on iOS and Android Widgets on Android, you'll have to create some conditional rendering, which decides wether to render iOS or Android components.
Sidenote: The Material-style Widgets look also really good on iOS. Also you can use a ton of other Widgets to create an UI in your own style.
I am trying to use both bokeh and matplotlib in my IPython notebook... Neither work perfectly.
Attached is a screen shot of Bokeh. Matplotlib explanation is below.
Here are my system specs:
-Windows 7 with Vagrant
-Jupyter/IPython
BOKEH -- buttons are static images; there is no resizing, yet the graph is interactive
Should look like from this website: http://docs.bokeh.org/en/latest/docs/quickstart.html
MATPLOTLIB -- only static shots appear when it should be zoomable, etc (like bokeh)
1) read the documentation.
you would only change output_file() to a call to output_notebook() instead.
Which you did not seem to do above.
2) Why should it ? What di you do to make it zoomable ?
3) try not to post 2 unrelated question at the same time.
You appear to be using an older version of Bokeh. The issue with the CSS problems (button appearance) has been fixed for some time. As mentioned above, you will need to execute output_notebook() to load Bokeh for IPython notebook usage. For future reference, questions like this greatly benefit from providing as much information as possible (e.g., Bokeh and browser versions, platform information, etc.) Without that information it is impossible to diagnose problems with any certainty.
I'm starting the iOS development and need to find out what is required to create custom component. I have a few of them to build like star rating bar (which promising tutorial I've found here btw.) or download button with progress like it is in the App Store app.
Instead of searching for ready built solutions I would like to learn on how to build it thus my question, is there any up-to-date guides on how to accomplish it? Using OOP rules:) ofcourse as I'm used to it from ActionScript and JAVA.
I'm working on an UI in QML for an embedded linux (for now raspberry pi/raspbian, but the HW will change pretty soon). I'm using Qt 5.0.2
I integrated a QWebKit browser using the QML WebView.
I want to be able to know when an input field is focused, I found some solutions using JS (using addJavaScriptObject or evaluateJavaScript) but all of them are working for Qt4.7/4.8 and Qt5 seems to have drastically cut the number of usable methods for the QML WebView.
Do you know a way to get this information? can we do it directly in the QML files?
Thx,
Arthur
The jQuery VideoControl is documented here:
https://developers.google.com/tv/web/lib/jquery/#gtv.jq.VideoControl
It takes a set of VideoParms. That are not specified.
It is used in the sample templates on this page:
https://developers.google.com/tv/web/docs/gtv-templates
I've taken apart the templates, but I'm having difficulty creating a simple example of a standalone video control. In the templates, the sidenav and carousel code are tied to how the videocontrol works. There is a relationship between the keyController and behavior (behaviorZones) that I can not find an explanation for.
Is there a standalone example somewhere? What needs to be setup with keycontroller, css, and behavior to get this going?
I'm not aware that there is a standalone videocontrol.js sample but it should be possible to set it up. Most of the necessary pieces are inside videocontrol.js, in particular in the videocontrol's constructor and this function: gtv.jq.VideoControl.prototype.makeControl.
keycontroller mapping is used to handling key inputs and some of the CSS are dynamically controlled within JS so there might be errors if you just rip them apart straight from the Template. You'd have to debug it using a solid tool like Chrome Developer Tools. You can watch tutorials of this tool here: http://www.youtube.com/results?search_query=chrome+developer+tools&oq=chrome+develop&aq=0&aqi=g3g-m2&aql=&gs_sm=3&gs_upl=1972l4015l0l6142l14l11l0l0l0l0l207l1476l3.5.3l11l0
Otherwise please send your error traces and/or code snippet for debugging help.
