G4P Question - Create / hide second screen

Processing Libraries

@quark

I apologize in advance for my newbiness. I’m using Processing 3.5.3, G4P V4.2.1, and GUI Builder 4.3 in Windows 7 64 bit. I love your utility but in my newbiness I’m having a devil of a time trying to figure it out. I confess I can’t grasp how to find out how to do anything using the reference page at your link. I’m not new on how to program things in basic-like languages but I’m new to Java and confess most OOP policies just confuse me on what happens when.

Anyway, I’ve been playing around some and I wonder if you could give me an example using GUI builder. I’d like to create a main screen with a button on it that launches a second screen that covers/obscures the main screen completely. On the second screen is a button that hides/suspends/closes/obscures the second screen and returns the view and execution to the main screen. So I can switch back and forth. I can’t find an example to copy that from.

In the application I’m building the main screen runs a lot of display stuff and the second screen will be used to change a lot of settings.

Thanks in advance. I’m sorry to be reduced to asking like this but I’m stumped.

My website www.lagers.org.uk has several videos showing GUI Builder in action and there are a lot more guides for G4P so have a look there first.

I saw all those, thanks for them.

I need to make a button that opens a second window (there are examples for that) and one to go on the second window to close it. Sorry to bother you. Or. Where can I find out if there is a secondwindow.close or something? Most answers that come up in search are for previous versions.

Thanks.

The website guide to G4P explains that is better not to open/close windows on need rather to create them in setup and make them visible / invisible as needed.

There are plenty of examples of creating windows and you can use

window.visible(false); // to hide the window and
window.visible(true); // to show the window

you can add these statements to button event handlers.

I used the GUI builder from a fresh start.
I created a second window.
It got called “window1”.
I put a button on the second screen.
I edited the event handler for the button by adding the statement;
window1.visible(false);
and got
the function "visible(boolean)" does not exist.
I’m missing something basic here. And I’m reading all the documentation I can find. I’m learning lots of other stuff but not what I’m after. Please, I could use a clue.

I need to have one button on the main screen that shows a second window and a button on the second window that hides the second window and shows the main screen.

Thanks in advance for any more clues.

Try
window1.setVisible(false);
