How to Get Width and Height of Android Screen in Pixels with Java Android Display display getWindowManager ().getDefaultDisplay () int width display.getWidth () int height. Input("store", "children"), Input("store", "data")) can use any prop to trigger this callback - we just want to store the info on startupĬonst screenInfo = Here is a MWE of a clientside callback to get screen width and height:įrom dash import Dash, dcc, html, Input, Output, no_updateĪpp = Dash(_name_, external_stylesheets=) Large tablets, ipad or PCs with a touch screen will have this same zoom/scroll issue. However, this may not be a great solution either because this issue has more to do with touch screens than screen size. Since Dash callbacks run at startup, this can be used to configure the graphs for the screen size. In the meantime, you can use a clientside callback to get the screen width and height, then update the `dcc.Graph(config=…) in a callback. If anyone knows how to do this, please feel free to post an example in this thread. It looks like it could be an elegant solution. I wasn’t able to get anything like this working: But it would be nice to get a better solution. I typically just disable the graph zoom on all screen sizes as a workaround. Jump to Post All 6 Replies vegaseat 1,735 16 Years Ago Just an untested WAG. I’ve run into that problem too - where it’s difficult to scroll on a small screen because the graphs will zoom instead of scrolling the page. import pygame from pygame.locals import pygame.init() screen ((640,480), FULLSCREEN) get the size of the fullscreen display x, y screen.getsize() There is also a () call you can print. My previous post was for people who really are “new to dash and flask” Here's how to access the screen width and height: const screenWidth const screenHeight 1.2 The available screen size The available screen size consists of the width and height of the active screen without the Operating System toolbars. I can do that with my call back but I need to get somehow the screen width or the device type.ĭo you know if i get the screen width or device type (user agent string) in python with any component in a dash app? Why I do that? Because scrolling plotly graph with the zoom “on” on a phone can difficult.īut I would like to make it automatic or at least to get the default choice automatic when loading the app. I already got the possibility to change that manually with a button and a call back. More specifically I want to make the plotly graph static if the screen width is small (xs as it is called in the doc. However the reason I am asking to the user agent, and understand if device is mobile, is because I want to change the graph config if the device is mobile, i.e. So if you are developing only for one specific resolution, you can use Device dimensions, otherwise it is suggested to use Logical dimensions with the scale mode you find suitable.I am actually already using bootstrap-components row, columns and container to adjust the columns width as a function of the screen width which is great! They basically will be scaled based on the scale mode you choose. ![]() No matter what resolution you have, the logical dimensions will always be the same. The easiest approach will be to not worry about the exact size of the window and instead maximize your window to take the entire display regardless of the size. ![]() You could create a window that's 'hidden' (set alpha0 when creating it), then get the size of the screen, then resize the window. Meaning on an iPhone 3GS it will return width as 320īut logical dimensions are exactly what you set in your project properties. In order to do that, you much first create a window. You should use W = application:getContentWidth(), H = application:getContentHeight() which would return logical dimensions that are used when in scaling mode.īasically it all brings down to these points:ġ) Choose the scaling mode that is proper for your game (Letterbox being most popular)Ģ) Choose logical dimensions for your game and create all the graphics for logical dimensions you set in the project properties (recommended 480x800 or 640x960)ģ) Create backgrounds a little more bigger than logical dimensions to cover whitespaces on devices with different ratiosĤ) Use absolute positioning ( ) for objects that need to stick to sides of the screen as on screen buttons for exampleĥ) (Optionally) prepare bigger graphics in in some fixed ratio coefficient and use Automatic Image Resoltuion feature to automatically load them for bigger devicesĪddition: (Difference between device and logical dimensions)ĭevice dimensions is exactly what device has.
