Some Questions (unrelated)

1) Is there any way to remove the red dot used in scatter after it has been used, so that it can be used multiple times?

I want to clear the screen of the label and return it to its original form.  I got everything working with a clear button and setting everything back to normal.  But I just can't remove the red dot.

I tried to use 

scatter.do_rotation = True

scatter.do_translation_x = True

scatter.do_translation_y = True

but that just turns everything off. Is there an alternative that just removes the dot for reuse?

2} Does the

with self.canvas:
Color(1., 0, 0)
Rectangle(pos=(10, 10), size=(50, 50))
Color(0, 1, 0)
Rectangle(pos=(100, 100), size=(50, 50))

Produce only filled in rectangles?  Can it do outlines only?

3) Is there a way to prompt the user for input on the fly.  For example, after pressing a button could I ask the user to respond (perhaps to multiple items)?

[Elliot Garbus]

For 1, see: https://kivy.org/doc/stable/api-kivy.input.providers.mouse.html#using-multitouch-interaction-with-the-mouse

For 2: Rectangle does a filled rectangle, see Line to create an outline of a shape. https://kivy.org/doc/stable/api-kivy.graphics.html#kivy.graphics.Line

For 3: use a popup. https://kivy.org/doc/stable/api-kivy.uix.popup.html#module-kivy.uix.popup

I read through the section on mouse providers, but didn;t see any reference to the infamous red dot.  In the first paragraph it said On Linux systems...  I'm on a windows system.  Is there anything else that directly addresses the red dot?

[Dan Moormann]

I'm already using both rectangles and line(rectangle() and turtle to do some simple graphics.  Besides turtle (or creating many many label widgets)  Is there a way to put text directly to the screen?

[elli...@cox.net]

This works on Windows and Mac to disable the red dot.  The red dot is multi-touch emulation.

 

from kivy.config import Config

Config.set('input', 'mouse', 'mouse,disable_multitouch')

 

Let me know this is sufficient.

You would just create Labels to put text on the screen.  What are you trying to accomplish?

I tried the Config.Set(...) Eliot suggested but nothing happens when I invoke it.  The red dot is still there.  No error, just nothing.

I'm trying to find an alternative to Turtle that would let me place text directly on the screen in multiple locations and colors if possible.  If you still have access to any of my earlier code, try the draw option to get an idea.

I read the section on Popup and got the first example to work.  Couldn't get content=Button(...) to work at all.  Error Button is not defined.

I'm really looking for a way to prompt the user to input some data for various reasons programmatically.

I'm puzzled why so many of the examples I try do not work (Probably just me)

I frequently have to wonder which item to import to get something new (for me) to work.  Please include "from xxx import yyy" on more examples.

[elli...@cox.net]

For the config.set, make sure you put this at the very top of your file.  You want to execute the Config.set before kivy.app is imported.

 

You can use a Label to put the text where you want.  Set the size, put it in a FloatLayout or RelativeLayout and use pos or pos_hint to position the text.

 

I’ll put together a small popup example.  What do you want to do with the Popup?

Here is a popup example that uses Factory to instance the popup in kv.

 

from kivy.app import App
from kivy.lang import Builder

kv = """
#:import Factory kivy.factory.Factory

<MyPopUp@Popup>:
    size_hint: .7, .7

Here is another small popup example – perhaps a little more useful.  I added a text input.  I instanced the popup in app, just to show a different way of doing it – rather than using the Factory.

I like your second example better.  Trying to figure out how to make the textinput box in the popup automatically have focus when the popup is launched. Any suggestions?

Use the popup event on_open to set the focus.

Adding focus to the previous example:

from kivy.app import App
from kivy.lang import Builder
from kivy.uix.popup import Popup
from kivy.uix.boxlayout import BoxLayout
from kivy.properties import StringProperty

kv = """
<MessagePop>:
    title: 'Update Message'
    size_hint: .7, .7

    on_open: input.focus = True

[Dan Moormann]

Thank you.  I tried every other option but there.  Now it works great.

I got your stand alone code to work.  In trying to integrate it into my code, I can't figure out how to initiate it from a button in my main

I added all of the kv code to my kv file only  making changes to text and messages

I added all the kivy code at the bottom of my code inserting some print statement so see who;s executing

   MesagePop() executes before execution main loop

   RootBoxLayout executes before execution main loop

I tried MessagePop()  - nothing happens (no error)

I tried PopApp() - it gets there but nothing else

i tried RootBoxLayout() - nothing happens (no error)

Not sure where to go????

[elli...@cox.net]

Looking at the example I wrote.

In on_start():

                The Popup, MessagePop() is instanced and assigned to the instance variable self.pop

 

In the kv code:

RootBoxLayout:
    orientation: 'vertical'
    Label:
        id: msg
        text: root.text
    Button:
        size_hint_y: None
        height: dp(48)
        text: 'Update Message'
        on_release: app.pop.open()

app.pop is the instance variable pop that was assigned the instance of MessagePop(), the open() method opens the Popup.

 

If this is not sufficient to get things working, share your code.

popup - I added the on_release: app.open() to line 25 kvfile - still won't fire.

Line(rectangle...) - I'm trying to use a variable (line 229 main) to set the color before displaying the rectangle - defaults to white

You will need a copy of colorcodes.txt stored in downloads or change line 160/161 main to any other directory (included with my code)

There's probably a better way to do the lookup, but I couldn't get Table to work.

Lots of print statements (one of these days I'll figure out debug)

You have 2 app classes; you can only have one.  You are only instancing TutorialApp.

 

In the kv file you have a root widget, RootBoxLayout.  But in TutorialApp you are instancing ScatterTextWidget as the root widget.

 

In MessagePop there is an error. You have an on_release statement in the multiline on_release.

 

The color attributes in Color, need to be between 0 and 1, you have 255.  You can divide the color attributes you have by 255, to get them between 0 and 1 if you currently have them represented from 0-255. Or you can use kivy.utils.rgba.  https://kivy.org/doc/stable/api-kivy.utils.html#kivy.utils.rgba

 

There is a dict in kivy.utils called colormap, that maps the names of colors to their value.  It is not documented – but it is in there.  It is also used by the ColorProperty.  Take a look at the source code if you are interested.

If you want to open the popup in xtest, you could use Factory…

#:import Factory kivy.factory.Factory

 

            Button:  #xtest
                id: test
                name: 'test'

#                on_press: root.xtest()
                on_press: Factory.MessagePop().open()
                text: 'xtest'
                background_color: 128,128,128,1     #grey
                color: 'black'

 

Or to use the xtest method, instance the MesagePop, and then use the open method.

def xtest(self):
    # popup
    print('xtext pop')
    # RootBoxLayout()
    MessagePop().open()
    return

Another issue:

    Color(xxc[i - 1])
    Line(rectangle=(xx1, xy1, xx2, xy2))

    Color(0, 1, 0)
    Rectangle(pos=(100, 100), size=(50, 50))

xcc is a string, not a tuple.

I see this is from colorcodes.txt file.  I’d recommend storing the data as json, use the json module to parse and convert back to python data types. Or better yet use the kivy colormap in utils.

I changed xb to a list and converted xxn[i+1] to a tuple and still no color.  it does work if I explicitly type in (255,0,0) or (1,0,0) (see example code).  I also tried to put the tuple into the Color() before Rectangle and it defaulted to white.  It looks like Color() does not accept a variable.  If it does, what am I doing wrong?

xb = [1, 1, 1], [0, 1, 1], [1, 0, 0], [0, 1, 0], [0, 0, 1],\
[.5, 0, .5], [1, 1, 0], [0, 1, 0], [0, .5, .5], [0, 1, 0, 1],\
[.5, .5, .5], [.5, 0, 0], [0, 0, .5], [.5, .5, 0], [.75, .75, .75]

with self.canvas:
print(self.ln(),x,type(x))
x=tuple(x)
print(self.ln(),x,type(x))
Color(x)
Line(rectangle=(xx1,xy1,xx2,xy2))
Color(0, 255, 0)
Line(rectangle=(100,200,200,200))
Color(1,0,0)
Line(rectangle=(200,200,200,200))

Color(0, 1, 0)
Rectangle(pos=(100, 100), size=(50, 50))

Color(x)
Rectangle(pos=(200, 200), size=(50, 50))

Here is how I would do it – I would use kv to use the canvas so the bind is taken care of by kv.  You may have an issue where you need to bind on size or pos change.  Or simply move this to kv.

Or you could use the canvas from the Label…

 

from kivy.app import App
from kivy.lang import Builder

from kivy.properties import ColorProperty
from kivy.uix.label import Label


kv =

            rgb: root.box_color

            rectangle: (*self.pos, *self.size)

FloatLayout:

        for color in xb:
            box = ColorBox(text=str(xb[i]), box_color=color, pos=(x, y), size_hint=(None, None), size=(125, 50))
            self.root.add_widget(box)
