Scatter Covers whole display kivy

由 三世轮回 提交于 2019-12-04 16:10:37
im writing a paint app in Kivy (Python) and i orientated myself at the Kivy Paint Tutorial. But when I wanted to add a Scroll funktion (so you can move your painted things to the top, left, right...) i came to an problem. I added a Scatter, so everything that is drawn is inside the scatter and it is posible to move it all together. Now im trying to add a menu but it isnt possible to press the button, because it is covered by the scatter. I tried to put both in a Float layout, but it didnt worked. My code: from kivy.app import App from kivy.uix.screenmanager import ScreenManager, Screen from

Kivy RecycleView as an alternative to ListView? How does it work?

由 末鹿安然 提交于 2019-12-04 09:50:31
问题 I should preface that I'm still a newbie to Kivy. I tried looking for similar questions, but they were either outdated or unclear. I was looking for something to display a list of elements among which a used could select one to interact with other widgets (buttons and so on). I stumbled upon the documentation page on ListView, but it clearly states that ListView is deprecated and RecycleView must be used instead. Now the problem is that the documentation doesn't seem very clear (at least to

问题 Ok let's say I want that label in some widget to use text from label inside another widget: <SubWidget@RelativeLayout>: Label: text: str(root.parent.ids.first.text) <RootWidget>: Label: id: first center_x: 100 text: "text" SubWidget: id: second center_x: 200 This works but doesn't seem to be nice solution. If I'll place first inside another widget I'll need to change reference to that it everywhere in the code (that can lead to errors). My first idea was at least to store reference to first

Python/Kivy : Call function from one class to another class and show widget in Python

由 烈酒焚心 提交于 2019-12-03 14:15:19
问题 I am using Python-2.7 and Kivy. When I run test.py then a show button shows. When I click on the show button then a label and value shows. I am fetching it from the database but now I defined it as a static array. When I click on Item1 label then call def open_form and pass id 11 after calling EditPopup(self) with id and show a popup with value. After that I change itemCode and click on the ok button then it updates data in the database. After that I call Invoice().abc() then it prints the

Problem with Kivy when trying to scrolldown vertical ScrollView with an horizontal ScrollView inside

问题 Ok, so I'm building something with Kivy(1.11.1) and summarizing I have a ScrollView that scrolls vertically and inside it there are some others ScrollViews but these ones only scroll horizontally, the problem is that whenever I scroll the outer ScrollView down and the mouse position gets into the inner Horizontal ScrollViews the outer Scrollview stops scrolling down, it looks like once the mouse position collides with the horizontal scrollview the scroll behavior stops being sent to the outer

How to duplicate blocks of widgets in kv file (lowercase-only rule)

由 此生再无相见时 提交于 2019-12-02 08:27:43
I try to understand how kivy .kv files work, so I created a small application with a horizontial BoxLayout which contains three GridLayouts, as shown: my_widget: <my_widget@BoxLayout>: orientation: "horizontal" GridLayout: rows: 3 ToggleButton: Image: Label: GridLayout: rows: 3 ToggleButton: Image: Label: GridLayout: rows: 3 ToggleButton: Image: Label: No problem there, but since there are same blocks of widgets (GridLayouts) could they be duplicated? I tried something like: https://kivy.org/docs/api-kivy.lang.html my_widget: [my_widget2@GridLayout]: rows: 3 ToggleButton: Image: Label: <my
