font-color de FileChooser

Question

Je voudrais savoir comment changer la couleur de police (texte-couleur) de FileChooserListView et de FileChooserIconView.

Je pourrais changer la couleur de fond (au blanc), et je voudrais changer la couleur de police au noir.

Comment est-ce que je pourrais faire cela?

Le style par défaut du widget Kivy est placé dans le fichier kivy/data/style.kv. Vous pouvez copier ses entrées et les modifier à votre guise. Par exemple:

from kivy.uix.button import Button 
from kivy.uix.boxlayout import BoxLayout 
from kivy.app import App 
from kivy.lang import Builder 

Builder.load_string(''' 

<FileChooserListView>: 
    # -------------------- 
    # ADD BACKGROUND COLOR 
    # -------------------- 
    canvas.before: 
     Color: 
      rgb: 1, 1, 1 
     Rectangle: 
      pos: self.pos 
      size: self.size 
    layout: layout 
    FileChooserListLayout: 
     id: layout 
     controller: root 

[FileListEntry@FloatLayout+TreeViewNode]: 
    locked: False 
    entries: [] 
    path: ctx.path 
    # FIXME: is_selected is actually a read_only treeview property. In this 
    # case, however, we're doing this because treeview only has single-selection 
    # hardcoded in it. The fix to this would be to update treeview to allow 
    # multiple selection. 
    is_selected: self.path in ctx.controller().selection 

    orientation: 'horizontal' 
    size_hint_y: None 
    height: '48dp' if dp(1) > 1 else '24dp' 
    # Don't allow expansion of the ../ node 
    is_leaf: not ctx.isdir or ctx.name.endswith('..' + ctx.sep) or self.locked 
    on_touch_down: self.collide_point(*args[1].pos) and ctx.controller().entry_touched(self, args[1]) 
    on_touch_up: self.collide_point(*args[1].pos) and ctx.controller().entry_released(self, args[1]) 
    BoxLayout: 
     pos: root.pos 
     size_hint_x: None 
     width: root.width - dp(10) 
     Label:

      # CHANGE FONT COLOR

      color: 0, 0, 0, 1 
      id: filename

      text: '{}'.format(ctx.get_nice_size()) 


<MyWidget>: 
    FileChooserListView 
''') 

class MyWidget(BoxLayout): 
    pass 

class TestApp(App): 
    def build(self): 
     return MyWidget() 


if __name__ == '__main__': 
    TestApp().run()
