gnuradio-companion --qt can't use aarow up / aarow down keys to change block IO type.

[chrisjohgorman]

What happened?

Placed Multiply Const block in a flow graph. Select the block and try to change the IO type by using up / down aarows. Fails to change type. Changing IO type has to be done by double clicking on the block.

System Information

OS: Arch Linux
GR Installation Method: Source

GNU Radio Version

3.10 (maint-3.10)

Specific Version

3.10.10.0

Steps to Reproduce the Problem

Under the gtk gnuradio-companion widget set, a block can be placed on the screen and using the up / down aarows change the IO type. This is not possible yet with the qt widget set.

Relevant log output

No response

Specifically, in GRC GTK the up/down arrows change the value of the first parameter of the block. I think it would be useful in GRC Qt to modify that to change the IO port type field directly.
