PyGame: draw.rect() has invalid parameters

由 时光怂恿深爱的人放手 提交于 2019-12-08 13:55:47
问题 I'm trying to learn mouse events with PyGame, and I'm trying to draw a box wherever the user clicks. I'm setting a variable equal to pygame.mouse.get_pos(), and calling individual tuple members according to the mouse's x, y position. Here's the code: import pygame, sys pygame.init() screen = pygame.display.set_mode((800, 600)) mousepos = pygame.mouse.get_pos() while True: for event in pygame.event.get(): if event.type == pygame.QUIT: sys.exit() if event.type == pygame.MOUSEBUTTONDOWN: pygame

NSEvent and Magic Mouse

由 a 夏天 提交于 2019-12-08 13:49:34
How do I distinguish whether the event -(void)scrollWheel:(NSEvent *)event was triggered by a Magic Mouse or a trackpad? The reason I'm asking this question is because I want to assign a different action to the scrolling event when a trackpad is used because the user can pinch to zoom on the trackpad. On the magic mouse, however, the user can't pinch easily, so I want to use the scrolling function as a substitute for pinching. I can distinguish between a normal mouse and a Magic Mouse using this line: if (([event momentumPhase] != NSEventPhaseNone) || [event phase] != NSEventPhaseNone) However

Python Tkinter - canvas scrolling with mouse position

由 北城余情 提交于 2019-12-08 12:24:38
问题 I think this is a very common question, but I couldn't find the answer. I'm trying to make a window that scrolls depending on the mouse position: if the mouse is close to top of the screen, it scrolls to the top, if it is close to the right border, it scrolls to the right and so on. Here is the code: from tkinter import * from tkinter import ttk root = Tk() h = ttk.Scrollbar(root, orient = HORIZONTAL) v = ttk.Scrollbar(root, orient = VERTICAL) canvas = Canvas(root, scrollregion = (0, 0, 2000,

Detecting if a mouse is wireless

由 孤者浪人 提交于 2019-12-08 11:33:33
问题 I am trying to detect whether a wireless mouse is present on a computer. I would like my program to run in the background. I would prefer to do this in Java however if this goes beyond Java's capabilities I can use another language. Can someone please get me started? (This seems like a Google-able question but I cannot find anything) 回答1: This is beyond Java and is highly OS-specific. You have to query the appropriate device drivers for the operating system; for example, on Linux this would

Javascript (jQuery) limit mouse movement speed inside an element

由 坚强是说给别人听的谎言 提交于 2019-12-08 09:45:40
问题 The task is to draw a curve ob canvas. The problem is that if mouse is moved too fast, the coordinates are skipped and not captured. (Html5/Js canvas capturing mouse coords when it moves fast - my previous post..) Is there a cross-browser way to limit mouse speed inside an element (div, canvas, etc.)? 回答1: I assume by "limiting mouse speed" you actually mean enable capturing high volume of mouse events so that you get more detailed information, or resolution, of the mouse path.
