mouseevent

问题 I use Shapes and Canvas, I want to make something like a mapeditor. When the mouse move over the canvas I draw the actually selected object to the canvas at the mouse position on every move, so who use the program can see how it will look like if the object is placed there. And on mouse click I add the current object/position to a list, which contains the placed elements which need to be drawn on the canvas in every update. The problem is if the mouse move handler is active (binded to canvas)

问题 I hava a Java swing application that use a 'pan-able' JComponent to display large data. When the user move the mouse wheel, I listen to these events, and update the content of the JComponent from the scrolled amount. I would like to have a different behavior depending on whether the user is using a classical mouse using a touchpad, as the ones that can be found on modern Mac laptops. How could I detect that the user is using the mouse wheel vs the trackpad to generate the scroll event? I am

问题 what i need to do is that I need to control another application installed on the same machine using my custom application. For example if i needed to use the standard windows calculator I would simply send the input events to the calculator. I have used some code snippets to make this possible and I have now triggered both mouse and keyboard events. but the problem is that i can be sure that the keyboard event will hit the target application because it has the process handle. but i cannot be

问题 A couple years in now, there's still something about mouseEnabled I'm not getting. I have a Sprite (for example here "Sky", that contains many objects, one of them is a Cloud, which I do not want to receive Mouse Events. I overlay this Sky on some other display objects.

问题 I need to capture screen (as print screen) in the way so I can access pixel color data, to do some image recognition, after that I will need to generate mouse events on the screen such as left click, drag and drop (moving mouse while button is pressed, and then release it).

问题 I'm making a game in pygame with a pressable button, but I want it to do only one thing when clicked. The code below prints "button pressed" for as long as you hold it down. What's an elegant way to change this code to make it only print that once per click? import pygame import sys pygame.init() screen = pygame.display.set_mode((640, 480),0,32) clock = pygame.time.Clock() def makeButton(x,y,width,height): if x + width > cur[0] > x and y + height > cur[1] > y: if click == (1,0,0): print
