Hi all,

I'm trying to make a delay on a signal with a variable delay with a WX GUI Slider. When i run the simulation and try to add a delay on a sinusoidal signal it gives me this error:

This is a problem with typing between Python and C++. The delay block wants (demands, really) an integer value, but your slider is passing back a float. In the delay block, cast it as "int(delay_slider)".

Also, you can use the delay block from GNU Radio; it allows variable delays. There's nothing wrong with using the blocks from gr-baz, but I would recommend you use blocks that are directly part of GNU Radio when they are available. Mostly because more of the community will be more familiar with them.
