Mouse click and drag not working1/3/2024 ![]() This should refresh the connection of the mouse to the USB receiver. If it is a Unifying device, then try having the mouse un-paired/re-paired to the receiver by using the Logitech Unifying Software. ![]() A sunburst or an asterisk logo printed at the bottom side. You will be able to tell by looking at the bottom side of the mouse for the Unifying Logo. What we can recommend you to do is to verify first if the mouse is a Unifying capable device. Allow us to assist you with your Wireless Mouse M325 concern. Print(s.type, s.event.Thank you for reaching Logitech! Apologies for not providing a prompt response. ![]() The process in the loop then repeats.ī = sphere(pos=, radius=0.2) The triggering of a "ball" event also breaks through the scene.waitfor in the while loop that was waiting for a "ball" event. With this triggering of a "ball" event, function f receives the triggered arguments in ev and sets the sphere's color to blue. When you click, the function t is executed, and in this function a sphere is created and a new type of event, "ball", is triggered by igger, with the optional argument b, representing the new sphere. In the following sample program, first you see a box, then the while loop halts waiting for the custom "ball" event to occur. In the program shown above, if you specify scene.one for the mousedown event, you will be able to drag just one sphere.Ĭustom events: You can set up your own custom events using igger. Just one: If you use scene.one instead of scene.bind, the binding occurs for just one event and then is automatically unbound. In the program shown above, if you place scene.unbind("mousedown") in the mouseup event, you will be able to drag just one sphere. Unbinding: After binding a function to a mouse event, you can unbind the function, in which case Web VPython will no longer send events to your function. Here is a function bound to both mousedown and mouseup events, either of which will cause a sphere to be created: Multiple event types: You can bind a function to more than one type of event. Other mouse events: You can also watch for mouseenter (the mouse is moved from the outside of the canvas to the inside), mouseleave (the mouse leaves the canvas), and click. ![]() It is also possible to use "anonymous" (unnamed) functions, an extended feature of the RapydScript-NG Python-to-JavaScript compiler, as shown here (this will NOT work with installed Python): While being dragged the sphere is red, but its color changes to cyan when the mouse button is released. Here is a complete routine for repeatedly creating and dragging a sphere, so that you can arrange many spheres on the screen. The way you detect these mouse events is by writing functions that are bound to the mouse events using scene.bind, and Web VPython will execute these functions when these mouse events occur. These are mousemove events.ģ) Conclude the drag when the mouse button has been released (a mouseup event). Here is the sequence of mouse events involved in dragging something:ġ) Determine that the mouse button has been depressed (a mousedown event).Ģ) Continually watch for the mouse to move, and use to update positions.
