I Want to Add Text on the Button

Murphy · July 17, 2019, 7:56am

Hello my dear friends,
I am adding button for open the led. I want to write text on the Button. I am adding text but I can’t see this. Text is under the Button. I want to see that. I am sharing codes. I want to text “START” and “STOP” on the Button. Thanks for reading…

looks like you use

draw without background
the filled rectangle in draw ( 60 times per sec )

but the text() you draw in setup only, so it might be visible
in the very first screen only.

Led System Turn on/off ,
here i give you a working toggle button already, you not like it?

also i recommended there to work in steps, as long your button not works
forget the arduino stuff, 90% of the processing users will avoid your
question when they see this / even the arduino part is not used at all inthere…

Firstly, Thanks for return my dear Friend,
You didn’t help me. What can I do for add text on the Button? I need help. I want to add text “START” and “STOP” on the Buttons. I don’t know where I add text. I hope so you can help me…

kll · July 17, 2019, 8:38am

-a- you must do the
https://processing.org/reference/text_.html
after the filled rectangle
-b- you should prepare 2 string variables with that 2 texts
-c- you should prepare a 3d. variable ( the one you feed to text(…) )
what you fill with the related of the first 2 string variables, depending on the
status of your toggle button
if button is

OFF text should be START
ON text should be STOP
( that is what i mentioned in my first answer as "reversed SETPOINT " )

-d- the full code i give you already ( and i see your LIKE there, so i expected that you tested it )

Firstly, Thanks for return my dear Friend,
The answer I’m looking for is great at this but I want to stay stable on the Button. It should show me everytime. I don’t want to click and see text. I want to see text everytime.
