Hello, i would like to add a mouse hover behavior for kivy widgets. It uses kivy WeakProxy instances and iteration loops, should be as efficient as it can be in python.

This has been asked before and we have some old closed issuesand various findable post on google. Edit: current example app in gist. Kivy on desktop by default is very bare bones right now, people do expect hover effects and various other things in desktop apps that we don't have right now. Another issue is code duplication, if we add sdl cursors or some other things, hovering will have to be duplicated in each module.

I guess it's more that the api seems needlessly complex and doesn't mesh very well with the kivy way of handling events like touches. It's also quite difficult to understand what the code is doing and the reasons for the various things there, which makes it harder to maintain in the long term. Some of the choices seem a bit arbitrary and specific to something that you use but may not apply to a general hover type of behavior. That's why I thought it should be in garden rather than in core.

Aside of that there are certainly a few technical issues, like the fact that it binds at import time and is imported by default, so create lot of dispatching on desktop for all apps.

But i feel the issues are mostly conceptual, hence i think garden being possibly a better place. On the other hand, it's certainly a good idea to have a discussion about how to bring that feature.

Hover grab is mostly for sliders, as you can see in example. Otherwise you just bind on hovering. About the import, i guess that it would be fine to have an if statement in init that binds on Window. Before the code, it's important to get a clear agreement on the idea, because once we merge a feature, we kind of have to support it, and make future code works well with it.

I know touch is not dispatched on mouse motion, but you are binding on mouse mouvement, and updating the widgets that asked for it, trying to only do that for the top level one, it feels like maintaining the order will be a burden in any complex app, and will look like double accounting, from managing your tree, and the height of your widgets, which can now be contradictory, and cause unexpected behaviors. I would rather i think, i have not really tested the idea have the dispatching follow the same path as the touch info, being managed by the widget base class, for example, a widget would be hovered by defaultif the hover events collides it but not any of its children, and that would cascade.

It then would be an integrated part of the way the widget tree behaves.

Anyway, it's just an alternative idea, that i feel would be more in line with kivy's way of working, and produce less incoherence in the API, the point is to discuss how to achieve best this feature. Could do a dispatch for Window children first for popup, then on app. Only problem would be that higher widgets have to be before lower widgets in children list. I guess that it wouldn't be too hard to work with that, just worse performance.

Well, you don't have to do any these things manually. You just dispatch it to the window which automatically takes care of the depth thing. I don't like adding one specifically for just hover. The dispatch would add new methods for Window and all widgets, and make it more complex.

I'm thinking that we just a generic event that can be percolated down the widget tree. Similar to touch. But if we can think of a way to add a profile in a backwards compat way maybe that's better. Because even a hover has down startmove, and up end concept. But I cannot see how we can do that. On second thought, a touch does have a beginning and end while a hover doesn't because the mouse is always somewhere similarly for the eye.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

I am designing a desktop kivy app where mouseover events for certain widgets would be quite useful. This has been discussed before. I believe for this reason it was considered better to leave it to users. If anything, it would probably be best to make a behavior mixin class like the ButtonBehavior that can keep track of the specific classes listening for hover events and dispatch relatively efficiently to them.

This wouldn't be very hard to create, if you wanted to make one and submit a PR I think it would be considered. Edit: I'm going to close this issue for now as I think we don't have this as a goal and the tools to do it are already available fairly simply.

It can be reopened if others disagree, or if you submit a PR that's still fine. Attached is my attempt for such thing. Posting it here, before any PR hoverable.

Behavior Kivy If I press down in kivy I see the arrows registering the mouse-down but the dots are light-red afterwards. They should be dark-red, shouldn't they? It was working dark-dots while pressing down and move with the old CEF. It is only being called after I click and hold down mouse button and then move.

Using Kivy 1. Missing mouse move events issue described in previous comment, I think needs to be resolved first. The second issue - of light-red dots when moving mouse while holding mouse button - I think is related to the first issue due to some mouse events missing. Commit that is supposed to fix it updates WindowPygame. This can be access inside widget using self. The main issue of mouse move events fixed in commit 7b8d7e9. Second issue of light-red dots fixed in commit e2d5.

Just for clarification: I never meant that the "hover" state should be implemented when I created this issue in Kivy as on touch applications there is no hover state by design - yet. However I think it is good you implemented it here for demonstration - even it does not work with all kivy window providers.

Maybe down the line allowing others to connect and use it too. And everything blew up. Now that I am older and wiser less stupid, I can face the fact that local data is best served with a desktop native application.

I then looked into alternatives, such as wx and Kivy. Lets just say a quick view at both of their home pages tells you plenty about who you trust more with front end design off the bat. Even thought Kivy seems to be aimed at more mobile development, including touch capabilities, I have found it to be extremely capable as a desktop application.

Just like any good python GUI, Kivy was a pain in the arse to install.

Wow classic statistics

On my Linux VirtualBox, ended up having to disable 3D acceleration for it to start. However, once I was able to start coding, it became stupid simple to be able to get content on the screen fast, and manipulate them.

After about four hours of coding in one night, I had this:. An image viewer app that could display any directory of images. It included a preview bar that you could select past or upcoming images from, and control with either mouse clicks or keyboard presses. Here is a simple visual diagram of what they look like, and the Kivy widget classes they are using.

The padding is for visual ease only, not part of the program or to scale. Simple right?

First steps into GUI design with Kivy

Well, now add two of those objects in base layout. Then on top of that, you can start mix and matching, hinting and absolutes with different elements on the screen. I chose to do that in this case, because I always wanted the preview bar of images at the bottom to be only px tall. But I wanted the large image to expand to the full height.

You can notice we also have make sure that the right hand button always looks attached to the right hand of the screen.

Which I later learned could probably be accomplished with the RelitiveLayoutbut am still unsure how that would work compared to everything else I already have with my FloatLayout. So I have am image viewer, great! But you want to organize images into more manageable groups. After that I am sure I will want to create a database system to store tags, album info and thumbnails for faster preview loading.
