shapes

I'm making a program that draws some shapes and fills them with color. I need to change the 'line' color, and want the user to be able to select the color. How can I, when clicking a button "Choose Color", have a set of colours appear below the button? Is it possible for the selector to be embedded in the UI below the button (and not pop up in a window)? I want to display a color selector like in Paint. Here is a colour selection button class: shows current selected color opens a JColorChooser dialog when pressed fires events when a color is selected Use it in this way: ColorChooserButton

I am trying to create beautiful speech bubbles in swing but the result is not very good...I mean I want something better and more beautiful! here is the code i'm using: import javax.swing.*; import java.awt.*; import java.awt.geom.Area; import java.awt.geom.RoundRectangle2D; public class BubbleTest { public static void main(String[] args) { try { for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) { if ("Nimbus".equals(info.getName())) { javax.swing.UIManager.setLookAndFeel(info.getClassName()); break; } } } catch (ClassNotFoundException |

It seems that the WPF Rectangle shape does not have the Click event defined. What am I supposed to use instead? It does have MouseUp, but it's not quite the same behavior. Kent Boogaart If you're not happy with MouseDown and MouseUp , perhaps you could just put the Rectangle in a Button and handle the Button 's Click event? <Button> <Button.Template> <ControlTemplate> <Rectangle .../> </ControlTemplate> </Button.Template> </Button> It really depends with the behavior you're after. Please elaborate if needs be. To add click handing to a Rectangle itself, you can use the InputBindings property:

Does R have a package for generating random numbers in multi-dimensional space? For example, suppose I want to generate 1000 points inside a cuboid or a sphere. Also check out the copula package. This will generate data within a cube/hypercube with uniform margins, but with correlation structures that you set. The generated variables can then be transformed to represent other shapes, but still with relations other than independent. If you want more complex shapes but are happy with uniform and idependent within the shape then you can just do rejection sampling: generate data within a cube that

I am trying to make a drawable to use for a button. I would like it to have this coloring, with a 2px border around it. Everything works just fine except I cannot get the border to show up... <?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" > <gradient android:startColor="@color/bar_clicked_dark" android:endColor="@color/bar_clicked_light" android:angle="90"/> <corners android:bottomLeftRadius="0dp" android:topLeftRadius="15dp" android:bottomRightRadius="15dp" android:topRightRadius="0dp" /> <stroke android:width

I have been searching for possibilities to define different shapes inside a single shapes.xml and refer to each one on some specific events. At last I've found a solution to my question. And the answer is using level-list. <?xml version="1.0" encoding="utf-8"?> <level-list xmlns:android="http://schemas.android.com/apk/res/android"> <item android:maxLevel="0"> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> <gradient android:startColor="#aaa" android:endColor="#eee" android:angle="270" /> <corners android:bottomRightRadius="7dp" android
