问题 This code is for drawing on a JPanel. In the paintComponent(Graphics) I am trying to draw curves via repeated Graphics2D#fillOval(x, y, with, height) . The app is working OK, and when I drag the mouse cursor slowly; it draws a continuous curve as I need. But when I speed up dragging the mouse cursor, the result is separated dots and not a continuous curve. So how to make it draw a continuous curve even if I speed up dragging? import java.awt.*; import java.awt.event.*; import java.util

问题 The program is an animation that creates a car and/or truck icon on the screen. The way I have it now it isn't working correctly. Specifically, the program is not clicking and dragging right. If one object is not-selected, once clicked on, it will become bolder to show that it is selected. From there we want to be able to drag it and the program will redraw the image wherever the mouse goes. If the image is un-selected, when I click and drag it, it works fine. The problem I am having is if

问题 I have made a small Conway Game of Life program. I'm about 80% done. I have used a grid of JButtons as the cells. Right now I have a ButtonListener on every button so you have to one-by-one draw the pattern you want by clicking on individual buttons. I want to be able to click and drag the mouse and select buttons quickly. I used the MotionListener class, implementing the MouseMotionListener and coded the mouseDragged method in an identical fashion as my actionPerformed method in my

Java Swing - Repaint() don't work correctly

问题 I take program from this topic. I try to edit points in real-time mode. I add MouseMotionListener to the constructor and write some basic functions to get near point to mouse and edit this point. When I get (x,y) points in the constructor, repaint() works strange. When I get (x,y) points in paintComponent , repaint() doesn't work at all. So, this are images with getting (x,y) in the constructor and in paintComponent . Where is my mistake? package simplegrapher2; import java.awt.BasicStroke;
