I'm trying to create a UI similar to BeReal's where there's a large image and then a smaller image in the top left corner of the larger image.
I've tried this solution:
MDBoxLayout:
size_hint: None, None
size: root.size
orientation: "vertical"
canvas:
Rectangle:
src: "Image1.jpg"
FitImage:
source: "Image2.jpg"
size_hint: .2, .3
pos_hint: {"center_x": .3, "center_y": .7}
I'm using the canvas to display the larger image as a background image and then adding the smaller one to the BoxLayout. This doesn't work, however, as the background image doesn't take up the entire screen and seems to be colliding with the smaller image.
Is there any way to replicate BeReals UI in Kivy?
Use a MDFloatLayout instead of a MDBoxLayout. ie.
MDFloatLayout:
FitImage:
source: 'image_cover.jpg'
pos: 0, 0
size_hint: 1, 1
FitImage:
source: 'top_left_image.jpg'
pos_hint: {'x': 0.01, 'top': 0.99}
size_hint: 0.45, 0.45
radius: 36, 36, 36, 36
Something like this?
Screen:
FitImage:
source: "Image1.jpg"
FitImage:
source: "Image2.jpg"
size_hint: .2, .3
pos_hint: {"center_x": .3, "center_y": .7}

My goal is to set the checkbox on top of the image in below class. I'm struggling to find a layout in which I can position one layout above another. The only way I could think of at the moment is to show the image as the background image of RelativeLayout not as AsyncImage but I believe there is a clean way to achieve this.
Class
<FriendTile>
orientation: 'vertical'
size_hint: None, None
height: pic.height + username.height
width: pic.width
background_color: app.alert_color
active_color: app.main_bcolor
unactive_color: app.main_bcolor
canvas.before:
Color:
rgba: (0, 0, 1, 1) if self.background_color is None else self.background_color
Rectangle:
pos: self.pos
size: self.size
RelativeLayout:
id: pic
size_hint: None, None
size: 100, 100
CheckBox:
size_hint: .1, .1
pos_hint: {'top': 1, 'right': 1}
canvas.after:
Color:
rgba: (0, 1, 0, 1)
Rectangle:
pos: self.pos
size: self.size
AsyncImage:
id: image
size_hint: .9, .9
pos_hint: {'center_x': .5, 'center_y': .5}
source: root.avatar
canvas.before:
Color:
rgba: (0, 1, 1, 1) # if root.background_color is None else root.background_color
Rectangle:
pos: self.pos
size: self.size
Expectations
Reality
I a creating an app in Python using Kivy, but when I use this GIF which has a transparent background, a grey box appears around the GIF. I don't understand why this is?
Here's the grey box (the dots are the gif):
The GIF in question: https://ibb.co/dMnxWVW
And here's the Python code for the GIF:
def on_press(self):
self.ids.mic_image.anim_loop = 0
self.ids.mic_image.source = "Mic_Pressed.gif"
And here's the .kv code for the GIF:
Image:
source: "Mic_Pressed.gif"
opacity: 0
anim_delay: 0
size_hint: (0.6,0.6)
pos_hint: {"center_x":0.5, "center_y": 0.2}
Image:
id: mic_image
source: "Mic_Static.gif"
opacity: 1
anim_delay: 0
size_hint: (0.6,0.6)
pos_hint: {"center_x":0.5, "center_y": 0.2}
Button:
id: mic
background_color: (1, 1, 1, 0)
pos_hint: {"center_x":0.5, "y":0.09}
size_hint: (0.2,0.19)
on_press:
root.on_press()
The app initially displays "Mic_Static.gif" (without any grey box). When the button (which is the same size as the GIF) is pressed, "Mic_Pressed.gif" is displayed, however it has the surrounding grey box.
I think it is an issue with your gif file. Try this replacement
I'm still learning kivy language .
please can you tell me how to add a border to a text in a label in the kv file
and thanks
In the kivy language documentation, you can redefine a widget's style by adding a - to the beginning of the kv rule. So, in the kv you can define a new widget like this:
<-LabelWithBorder#Label>:
border_width: 0
border_color: [1,1,1,1]
canvas.before: # draw the border
Color:
rgba: root.border_color if root.border_width > 0 else [0,0,0,1]
Rectangle:
size: self.size
pos: self.pos
Color:
rgba: 0, 0, 0, 1
Rectangle:
size: self.width - 2*root.border_width, self.height - 2*root.border_width
pos: int(self.center_x - (self.width - 2*root.border_width)/2.), int(self.center_y - (self.height - 2*root.border_width)/2.)
canvas: # modified from Label
Color:
rgba: 1, 1, 1, 1
Rectangle:
texture: self.texture
size: self.texture_size[0] - 2*root.border_width, self.texture_size[1] - 2*root.border_width
pos: int(self.center_x - self.width/2.) + root.border_width, int(self.center_y - self.height/2.) + root.border_width
The canvas.before is the section that draws the border, and the canvas section is the normal Label style with slight modifications to account for the border.
This can be used, for example, like this:
FloatLayout:
LabelWithBorder:
text: 'Hello, World'
font_size: 50
border_width: 10
border_color: [1,0,0,1]
size_hint: None, None
size: self.texture_size
pos_hint: {'center_x':0.5, 'center_y':0.5}
I believe you are looking for 'outline'
This is the docs link for it Label Outline - Kivy Docs
Here's some example code (color defaults to black .. 0, 0, 0, 1):
Label:
id: label_StackOverflowSample
pos_hint: {"x": 0.25, "y": 0.18}
size_hint: 0.6, 0.365
font_size: 18
text_size: self.size
halign: 'left'
italic: True
outline_width: 10
outline_colour: (0, 0, 0, 1)
text:
'''
long long long
long long long
long long long
long long long
long long long
textt
'''

I am looking for a way to change the file icon of FileChooserIconView and set it programatically. I am looking at Kivy's filechooser.py source code but cannot find where the icon is being set.
Currently, the default background color of FileChooserIconView is black and the current icon works well with that background. I need to change my app's background to white, and the current icon doesn't looks nice with white background and I also have a specific file icon that needs to be used for the white background.
The file icon is defined in the style.kv file of your Kivy installation. And it is referenced in the FileChooserIconView and the FileChooserIconLayout classes as:
_ENTRY_TEMPLATE = 'FileIconEntry'
You can redefine that template using something like:
Builder.load_string('''
[FileIconEntry#Widget]:
locked: False
path: ctx.path
selected: self.path in ctx.controller().selection
size_hint: None, None
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])
size: '100dp', '100dp'
canvas:
Color:
rgba: 1, 1, 1, 1 if self.selected else 0
BorderImage:
border: 8, 8, 8, 8
pos: root.pos
size: root.size
source: 'atlas://data/images/defaulttheme/filechooser_selected'
Image:
size: '48dp', '48dp'
source: 'atlas://data/images/defaulttheme/filechooser_%s' % ('folder' if ctx.isdir else 'file')
pos: root.x + dp(24), root.y + dp(40)
Label:
text: ctx.name
text_size: (root.width, self.height)
halign: 'center'
shorten: True
size: '100dp', '16dp'
pos: root.x, root.y + dp(16)
Label:
text: '{}'.format(ctx.get_nice_size())
font_size: '11sp'
color: .8, .8, .8, 1
size: '100dp', '16sp'
pos: root.pos
halign: 'center'
''')
The above code just duplicates the template definition from style.kv, but you can make any changes to the above template, and those changes will affect the FileChooserIconView. The Image is the actual icon.
The last letter is overflowing
I'm using Kivy 1.10.1. I've added a text input (multiline = False). The sentence entered above is "This is a long sentence being typed into Kivy". All the letters have been entered. But the last letter - the "y" is outside the text input.
I've tried changing the padding size, the border size and changing the size of the textinput itself. I don't know if I'm doing something wrong or it is a bug with the library.
Edit:( I should have added the widget code here )
text_input: input_text_field
canvas:
Color:
rgba: self.background_color_intensity_red, self.background_color_intensity_green, self.background_color_intensity_blue, 1
Rectangle:
size: 396, 768
pos: self.pos
source: "sprites/phone.png"
BoxLayout:
size: 354, 598
pos: 21, 96
orientation: 'vertical'
BoxLayout:
size_hint: 1, 0.1
pos: root.pos
orientation: 'horizontal'
Image:
size_hint: 0.15, 1
source: "sprites/profile_pic.png"
TextInput:
id: input_text_field
size_hint: 0.85, 0.5
pos_hint: {'top': 0.75}
background_color: 1,1,1,1
border: (20, 20, 20, 20)
multiline: False
halign: 'center'
focus: True
on_text_validate: self.parent.parent.parent.on_text_input()
BoxLayout:
size_hint: 1, 0.9
pos: root.pos
orientation: 'vertical'
Thank you.
