kandi X-RAY | controlp5 Summary
ControlP5 is a GUI library written by Andreas Schlegel for the programming environment Processing. The range of available controllers includes Slider, Button, Toggle, Knob, Textfield, RadioButton, Checkbox, Lists amongst others. These controllers can be easily added to a processing sketch, or displayed inside a separate control window. They can be organized in tabs or groups as well as rendered into PGraphics buffers. The state of a controller can be saved to file in JSON format.

The classpath separator is only
; (semicolon) on Windows. Since you're on Linux, you need to be using
: (colon) to separate classpath entries. Your shell is interpreting the semicolon as something totally unrelated and confusing Java.
Just replace all of the semicolons with colons in the command you're invoking.

Laancelot's idea isn't bad, however, due to controlP5's OOP architecture it might not be possible, or at least trivial, to extend the controlP5's Button class to achieve your goal from a controlP5 sketch.
I'm making the assumption this is connected to other LED ring related questions you posted around this time (such as this one).
It might be wrong (and I'd be interested in seeing a solution), but without forking/modifying the controlP5 library itself, the inheritance chain gets a bit tricky.
Ideally you'd just need to extend
Button and be done with it, however the method used to tell states (if a button over/pressed/etc.) is the Controller superclass's
inside() method. To work with your image you'd need override this method to and swap the logic so it takes into account the alpha transparency of your png button skin (e.g. if the pixel under the cursor is opaque then it's inside otherwise it's not)
Here's a rough illustration you were constrained to using a Processing sketch:
I am trying to write some program to display telemetry data on charts using Processing IDE. I use ControlP5 library to create chart. There will be many of them so I wanted to write some function that generates them, but there is some problem, I am not sure how to send chart name to the function. I tried using this but IDE throws some error:
The function create_chart(String, int, int, int, int, int, String) does not exist.
Here is code that I use:...

As pointed out by @Andy the
create_chart method is not defined within the
Dane class in the above code example. This should be fixed first.
If you didn’t intend to add
create_chart to a separate class, you might want to change

The problem list in:
I have 4 buttons that I've made from images using ControlP5 function. I wonder is there a way to make the clicks on them to be seen clearly. Right now there is no indication that they are being clicked. (Like a color change in the background of the button or any indication)
Here are the buttons:...

setImage you can use
setImages to add separate images for normal, hover, and down states.
Take a look at the example file for ControlP5button. You can open it in Processing by going to File > Examples... and looking for it in the ControlP5 folder.
In this part they load the 3 images for the button states for the play button:
The ColorPicker from cp5 is hardcoded and I can not resize the shapes of the sliders. So I extended the ColorPicker class and made a new one called MyColorPicker.
I have several groups and I want to add my new class to one of them.
Earlier, I could do it by
cp5.addColorPicker("") .moveTo("") But in this case there is a new class and I couldn't move it to the group. Here is the code pieces:

I would recommend fixing syntax errors before posting and also removing any code that may not be related to the issue. Trying to cleanup / minimise code that way made the solution obvious for me so many times in the past.
I'm not sure you can group groups within groups. I might be wrong and hopefully someone more experienced with cp5 can correct me if I'm wrong.
If you use a single group and fix the syntax errors you could run something like this:
I have 2 different LED Rings. (one has 16 LEDs and the other 24) I want to make an interface from processing IDE where I can select a color and send this color to the selected ring. Here is the arduino code:...

Reliable serial communication is not trivial. Ideally you would make you own binary communication protocol setting up a packet of bytes with a header that describes how many following bytes actually have data and perhaps even a checksum.
Strings will do to get started and it's great you're using
nf() to make data easier to parse.
One potential gotcha could be the switch between putting a string together (
rgbInput()) and reading one char at a time (
char val = Serial.read();).
I would recommend breaking the problem down into smaller simpler parts, testing/debugging each part, then putting the parts back together one at a time to avoid integration bugs.
For example, the main challenge seems to be serial communication so I'd write a Processing and Arduino sketch to ensure that works reliably before adding in LED control.
Let's go for the option of \n terminated strings, even though it's sending a redundant extra character(e.g.
port.write("2\n");) it would make buffering simpler:
- always buffer until a newline
trim()the string for newline
- if the trimmed string has length 1 it's a command (like '2', 'l', 't'), otherwise it's a colour triplet
Here's a basic Arduino sketch that uses the ideas above (and a bit of your code ;) ):
I want the "pick_one" and "pick_all" buttons to be inside another general button (like a file - or a new page in the interface) called "configuration" button. I've tried this code below but I get unexpected token: void error.
Is there a way to put the buttons inside of another button?...
ANSWERAnswered 2021-Aug-05 at 17:13
It looks like you are nesting the button click handler functions. These are the actions that get triggered when your buttons are clicked. They don't control the layout or nesting of the buttons on screen.
Also, nested functions are not allowed in Processing, which is why you're getting the error.
Make sure the braces for your
CONFIGURATION function don't contain any other functions:
I want to create a shape Object(in my case the object is a rectangle). Each time I click a button. Currently, I'm able to make it appear just once. The idea would be that each time I click the button, a new rectangle Object is created, additional to the old one. Therefore, if I click the button 5 times, I should have 5 rectangles.
I tried to do it with an
ArrayList, but still, there is just one rectangle appearing. Does someone know how to do it!
Thank you very much in advance!
This is the main class, FYI there is also a rectangle Class(not attached)...
ANSWERAnswered 2021-May-28 at 21:25
You have a list, but you never add anything to that list. The list remains empty.
Drop the member field
rect, delete this line:
I am trying to retrieve a method from the Rectangle Class in the Main Class, but it is not working. The goal would be that the user clicks on the Rectangle button and then a Rectangle appears. However, the rectangle must not disappear again. Additionally, the user should be able to change the properties (like size and position).
I am not sure if I should try the callback function? I would really appreciate your help!
Thanks a lot in advance!...
ANSWERAnswered 2021-May-27 at 19:55
It is in fact working (the
rect.draw() function fires when you click the button). You can verify this by placing a print statement in the callback function:
