Re: [Discuss-gnuradio] OOT: General type block changing parameter with WX GUI slider

[Federico 'Larroca' La Rocca]

Hi,

In any case, if you use WX or QT, you will have to create some setters methods in order to set these parameters on-line from a slider. I've personally never implemented those, but you should take a look at the code generated by any flowgraph that does. For instance, create a new flowgraph with a delay which you change from a slider, and check how it works. It should be rather straightforward.

Please don't use WX Gui widgets for new designs. We're deprecating them, and they are NOT part of the oncoming GNU Radio 3.8 release. Use Qt instead. We simply have no-one to maintain the WX GUI elements, and thus, it'll be very hard to help you with WX issues.

Best regards,

Marcus

Hi to all,

I created a module and its type is general. It has 6 inputs and 2 outputs. Also, there are 2 parameters. I noticed that I cannot change these parameters while the GRC is running(I am using WX GUI Slider). Actually, I can change them but my block uses the default value of WX GUI slider box.

In .cc file under the place where we define number of input/ouput ports, I declare them as

parameter1(p1),

parameter2(p2)

Then in the .h file, under the private, I declare them as

float parameter1;

float parameter2;

What might be the problem?

Best regards,

Ali
