Hi!

It seems like the command ui.present(style = 'full_screen') no longer gives a full screen view but rather a windowed view in the updated Pythonista. Anyone else seen this? Is this a bug or new behaviour?

Hi! Pardon me if this has been asked, I could not find it in the search.

I have made a drawing app that is working quite well. One thing I have not solved is the loading and saving of images, and instead of loading and saving from Camera Roll, I thought it would be better to save them to iCloud or Dropbox. Can Pythonista open a file requester to let the user save to the new Files system in iOS 11?

@JonB Thanks for replying. I am not that experienced in Python, so half of the release notes are cryptic to me 🙂 I see the notes mention saving to jpeg has issues, but my code does png. I guess it goes for the same?

I have the same issue with one of my scripts. This is the code that is causing the error:

def pil_to_ui(img):
	with BytesIO() as bIO:
		img.save(bIO, 'png')
		return ui.Image.from_data(bIO.getvalue())

The last line seem to be the one triggering the error message.

Hi!

I have done a pixel art app with Pythonista. Everything is working as it should, and the painting experience is great through Python. But I wish the app had palm rejection when I used my Apple Pencil. Does anyone know if that is possible with Pythonista?

Relieved it was such a simple fix. Thanks!!

Thanks @cvp! This is great!

Cool, saw your answer now!! I keep replying to fast :)

Cool, now most of the script seems to work as it should. Thanks again!

I changed the text assignment to this, and now it appears where I intended:

        # Sends the selected image to the pixel Editor
        self.superview['File Label'].text = selectedFile 

filePreview should exist though, should it not? I created it as an imageview a couple lines up, so is should be within the scope of the file window. Looks more like the function isnt called at all when I press the different table lines.

Here is how it looks right now:

import ui
from glob import glob
from os.path import basename

class fileWindow(ui.View):
    def __init__(self):
        self.frame=(100, 150, 300, 300)
        self.name = 'File window'
        self.border_width = 2
        print ('Loader superview at init:', self.superview)
        
        imagefiles = [basename(x) for x in glob('*.*')]

        
        filelistData = ui.ListDataSource(imagefiles)
        filelistData.delete_enabled=False
        
        filelist = ui.TableView(frame=(10, 10 ,150, 280), data_source=filelistData, name='filelist')
        filelist.row_height = 24
        filelist.action = self.fileSelected # This does not work...
        self.add_subview(filelist)
        
        filePreview = ui.ImageView(frame=(170,10,120,100))
        filePreview.background_color = 'black'
        self.add_subview(filePreview)
        
        loadButton = ui.Button(name='Load', frame=(170,120,64,32), title='Load')
        loadButton.background_color = 'white'
        loadButton.action = self.loadAction
        self.add_subview(loadButton)
        
        ui.delay(self.x,0.01)
        
    def x(self):
        print ('Loader superview type = ', type(self.superview))
        
    def loadAction(self,sender):
        selectedFile = self['filelist'].data_source.items[self['filelist'].selected_row[1]]
        print ('Selected ' + selectedFile + ' from sender: ' + sender.name)
        # Sends the selected image to the pixel Editor
        self.superview['File Label'].text = selectedFile
        
    def fileSelected(self,sender):
        # This does not work..
        print('Gonk!!')
        filePreview.background_color = 'red'
        
class pixelEditor(ui.View): 
    def __init__(self, width=640, height=480):
        self.bg_color = 'grey'
            
        fileButton = ui.Button(name='File', frame=(10,80,64,32), title='File:')
        fileButton.background_color = 'white'
        fileButton.action = self.openFileWindow
        self.add_subview(fileButton)
        
        fileLabel = ui.Label(frame=(100, 80, 300, 32), font=('HelveticaNeue-Light', 32), text='___')
        fileLabel.name = 'File Label'
        self.add_subview(fileLabel)
        
        print(self.superview)
        
    def openFileWindow(self, sender):
        fv = fileWindow()
        self.add_subview(fv)
        #fv.present()
        print('File window opened.')
    

v = pixelEditor()
v.present('fullscreen')

@cvp said:

print ('Loader superview type = ', type(self.superview))

Thanks,

I still have to do a fv.present() inside the openFileWindow function, right? The window will not show up otherwise...

print ('Loader superview type = ', type(self.superview)) now returns a NoneType, though.

I still want to put the selected file name into fileLabel.text - how would you go about doing that?

Thanks, that also worked. I had the sub-window opening OK a couple steps back as well. But the next problem still remains, though, even in this version.

I do a print ('Loader superview:', self.superview) when I init the fileWindow, to see that there is a parent view I can put the selected file into, but that still returns None. Is there a way to get the new view properly assigned as a child of the first pixelEditor view?

edit: I see you have made a new function that prints the superview, but it returns fileWindow. So the windows parent is itself? Why is the superview not pixelEditor?

Thanks for taking the time to help me out!!
