Hi all,

I'm working on a drawing application that's intended to have several popup windows in which I can configure the brushes.

You can find a rough sketch of the drawing tool here.

I've created a Window object which, upon creation, initiates a bunch of gui elements (using the fantastic controlP5 library) and draws a rect() as a frame.

After I've done setting the necessary parameters I want the Window to disappear again. Unfortunately I've run into two problems with that:

1. Obviously the rect() is drawn to the stage, but I don't want it to. It should disappear, revealing whatever it covered before. The only way I can think of around this, is to save and reload the underlying pixels after the window is gone But that feels a wrong thing to do

2. It's a snap to create a button with controlP5:
Code:

controlP5.addButton("button",10,100,160,80,20);
 

Unfortunately once it's created I can't seem to get rid of it again. It will constantly draw on top of everything else. Is there a way to delete created buttons/radios/sliders again? I stumbled upon remove() in the documentation, but I don't seems to get it to work. Andi?

True, I could use a controlP5 controller window for my popups, but I'd rather try without, because it wouldn't fit the overall look and feel of the application.

cheers,
Greg

jaylfk,

Not sure if I understand what you mean. I don't want the background to shine through while the window is displayed. And even if it does, the rect() still alters the pixels under it.
Or am I completely missing your point?

Ok, so I've decided the save/load-pixels-option works well enough, even though I still think it's not the cleanest way to go.

Basically what I do is create a window-object and before drawing anything to the stage I create a PImage with the pixels that are going to be covered:

Code:

PImage backgroundPixels = createImage(windowWidth, windowHeight, RGB);
windowPixels = get(windowXpos, windowYpos, windowWidth, windowHeight);
 

and then after I've killed the window-object, I can "restore" the pixels to their original values.

Code:

image(backgroundPixels, windowXpos, windowYpos);
 

One down, one to go. Now how can I get rid of the controlP5 elements?
I did try:

Code:

controlP5.remove(Controller closeWindow); // closeWindow is one of the buttons
 

but it gives me a syntax error (missing right parenthesis)? Or maybe I haven't figured out correctly how to adress a specific controller?

Andi,

Yeah this does the trick. Vielen Dank. That's one fantastic library you've put together! Looking forward to the final release.

One slight problem remains though. As intended I want to create popup-windows. For that purpose I add controllers as needed to controlP5, from within the popup-window class. It should be possible to create a button, that once pressed, deletes the window-object and removes() all controllers within the window.
But I can't get the controller event for these elements to work inside the class.

Code:

void closeWindow() {
   // delete window object
   controlP5.remove(controlP5.controller("closeWindow")); 
}
 

This only seems to register if I write it outside of the class. Any idea what the problem might be?

cheers,

Ok, thanks for the info. Luckily I'll still be able to achive what I want, even if it's not the most elegant way to write the code.

cheers,
Greg
