Good afternoon, I am using the switch construction, but I don’t know how to write correctly for other values after the case operators.
In the DisplayData code, in the switch construction, I assign a command number to the fields, for example: Vin = cp5.addTextlabel, so that later, when connecting via a com port, display or change the data by sending this command "60",123 in the Vin = cp5.addTextlabel field.
Only works in (minutess = cp5.addButton) - 10, (Vin = cp5.addTextlabel) - 60, (inputPULI = cp5.addNumberbox) - 40, (inputNapryzenieKV = cp5.addNumberbox) - 70
The main error is below (function "setText (String)" is undefined. See screenshot.
How do I fix this for variables and write it correctly?
ImageButton button;
RadioButton CheckBoxuvum; Documentation
CheckBox P4; Documentation
See the GUI file!
A task:
ImageButton (button) - 20, the goal is to get a picture change in the window by sending a command through a terminal or microcontroller.
P4 = cp5.addCheckBox - 30 CHECK, the goal is to get a change in the state of the checkbox on and off in the window by sending a command through a terminal or microcontroller.
CheckBoxuvum = cp5.addRadioButton - 50 +/-, the goal is to get a change in the state of the checkbox on and off (+/-) in the window by sending a command through a terminal or microcontroller.
In the Displaydata code, I marked this with a question.
In the future, I plan to send commands from the terminal via the com port to receive a change in the state of the data in the window for these values.
Screenshot of errors:
I will have to upload all the test project files so you can test this.

The problem is
default:.The switch run like this: it finds the case which corresponds to the key and starts executing code from this point on until it hits a
break;. Thedefault:case is a catch-all: it'll like a condition which would always be true.To illustrate, I like this example: here when the user enters a number, it prints to the console the names of all the month from that point up to December.
Notice how
defaultis at the end. That's because since it's always "true" and since the switch will select only one case and then run until abreakstatement, if I put it anywhere else it will always be selected when it's read. See by modifying the example like this:This is exactly what happens in your program. In
DisplayData(), right at tthe beginning there's adefaultcase which overrides all the other cases:You can re-write with the correct syntax like this:
Have fun!
