Parameter Dialog window: pressing Send button does not send the latest parameter value from the Input field

[stanislaw]

Is your feature request related to a problem? Please describe.

When I want to send a TC with a parameter using the Parameter Dialog:

• Step 1: I fill in a desired value in the Input field.
• Step 2: (I click on the white area of the parameters table to remove the focus from the Input field)
• Step 3: I press Send button.
• Step 4: The command with a correct parameter value is seen in tcpdump and embedded software.

The problem: one has to pay attention and always remove the focus from the Input field by clicking somewhere outside it (Step 2). Otherwise, the Parameter application sends the previous stored value of the field, not the latest one which is in the Input field that still has focus on it.

Describe the solution you'd like

Reading out the latest input value when the Send button is pressed would be a more intuitive behavior, aligned with my expectations.

I am happy to let this issue be resolved by someone else. I can also send a patch to address this but want to have the issue confirmed first.
