问题 I'm running an animation using matplotlib's FuncAnimation to display data (live) from a microprocessor. I'm using buttons to send commands to the processor and would like the color of the button to change after being clicked, but I can't find anything in the matplotlib.widgets.button documentation (yet) that achieves this. class Command: def motor(self, event): SERIAL['Serial'].write(' ') plt.draw() write = Command() bmotor = Button(axmotor, 'Motor', color = '0.85', hovercolor = 'g') bmotor

Scale Animation Causes View to shorten before start of animation

阅读更多关于 Scale Animation Causes View to shorten before start of animation

问题 So I have this scaling animation and what it's supposed to do is scale the view to 70% of the full height, and then scale it back to the original size. I have two scale animations with different startOffsets. The problem I'm having with this is the view scales before the animations even start. So when the animations start, they work with the already-shortened-scaled view. Here is my animation xml: <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res

How can I change the 'pivot-point' of this flip animation?

阅读更多关于 How can I change the 'pivot-point' of this flip animation?

问题 I've been playing around with this CSS3 Animation, but I can't get it to pivot from a different location than the middle. It is an animation that causes a flip-like effect from the middle where the top-half goes into the negative z-axis and the bottom-half goes into the positive z-axis. I am trying to get the pivot-point to be the top so as the element that this animation is applied to is transformed, the entire element goes into the positive z-axis. And then the flipOut animation would just

Is there a way to animate an entire Jframe in Java so that it moves?

阅读更多关于 Is there a way to animate an entire Jframe in Java so that it moves?

问题 I would like to create a program where the Jframe is able to move freely on it's own. Kind of like a translation / transition. For example, Click on program to begin. Jframe spawns at location (0,0). Automatically move (animate) 100 pixels to the right so that the new coordinates are (100,0). I know there's the setLocation(x,y) method that sets the initial position once the program runs but is there a way to move the entire Jframe after the program starts? 回答1: The basic concept would look
