Adding a widget in the root center

[Sergey Vdovin]

Hello.

I'm confused with a stupid problem. I'm trying to make a draggable widget that is similar to Popup and Scatter.

Expected functionality:

User press button "Search tab" - yellow draggable widget appears in the center of the window.

Problem:

The yellow widget appears in the left low corner.

I used a lot of different ways to handle the issue but no method succeded. Probably, I'm missing something very simple.

How would you solve it?

Main file - tmp3.py

from kivy.app import App

from kivy.lang.builder import Builder

from kivy.uix.boxlayout import BoxLayout

from tmp4 import tmpWidget

Builder.load_string('''

<tmpWidget2>:

orientation: 'vertical'

Button:

text: 'Search tab'

size_hint: 1, None

height: 40

on_press: root.search()

Label:

text: ''

size_hint: 1, 1

''')

class tmpWidget2(BoxLayout):

tmp = tmpWidget()

def search(self):

self.add_widget(self.tmp)

class Gui2App(App):

def build(self):

self.prog = tmpWidget2()

return self.prog

if __name__ == '__main__':

Gui2App().run()

Imported file - tmp4.py

from kivy.app import App

from kivy.lang.builder import Builder

from kivy.uix.boxlayout import BoxLayout

from kivy.uix.relativelayout import RelativeLayout

from kivy.uix.behaviors import DragBehavior

Builder.load_string('''

<tmpWidget>:

size_hint: None, None

size: 250,50

drag_rectangle: self.x, self.y, self.width, self.height

    drag_timeout: 10000000

    drag_distance: 0

BoxLayout:

orientation: 'vertical'

size_hint: None, None

size: 250,50

spacing: 5

padding: 5

canvas.before:

Color:

rgb:  1,1,0

Rectangle:

size: self.size

pos: self.pos

BoxLayout:

orientation: 'horizontal'

Label:

text: ''

size_hint: None, None

width: 20

height: 40

Label:

text: 'SEARCH TAB'

color: 0,0,0,1

size_hint: 1, 1

Button:

text: 'X'

size_hint: None, 1

width: 40

on_press: root.search_exit()

''')

class tmpWidget(DragBehavior, RelativeLayout):

def search_exit(self):

App.get_running_app().prog.remove_widget(App.get_running_app().prog.tmp)

Thank you in advance

I've made a workaround using FloatLayout instead of BoxLayout. Honestly, it's not the best solution for me. If somebody knows better way, I'll be gratefull listener...

The workaround is in attachment
