Swing/AWT/SWT :: JCheckBox Background Color Not Showing Up In Nimbus
Jul 17, 2014
I'm displaying a table with several read-only pieces of data, and a checkbox field that toggles the row color. The background color for the checkbox is not toggling correctly. I put together a SSCCE:
If I comment out the Nimbus look and feel, it works as expected. I googled this problem and found one possible solution on Stack Overflow. Their suggestion is:It's a bug in the synth-installed renderer, quick hack is to force the rendering checkbox opacity to true: ((JComponent) table. get Default Renderer(Boolean.class)).setOpaque(true);
I tried using this line and setting the opacity to true, but it renders the background white. I'm using Java 1.7.0_25.
I have added a background image to this JFrame (see image attached) as I want the buttons and field to just be on top of the image, how to remove the colored part of the JFrame that is left?
No problem setting background color for layouts, e.g. bdrPn.setBackground(new Background((new BackgroundFill(Color.BLACK, CornerRadii.EMPTY, Insets.EMPTY))));
But neither of the following are working for me, running JavaFX 8 on latest OS-X
scene = new Scene(bdrPn, winW, winH, Color.BLACK); scene.setFill(Color.BLACK); scene.setFill() worked fine for previous versions of JavaFX.
I've just started working on a program and i'm already having difficulties with the program. I can't get the background color to change from the basic gray color. Maybe you can tell me what i'm doing wrong.
import javax.swing.JFrame; import javax.swing.WindowConstants; import java.awt.*; import java.lang.Object; import java.awt.Color; public class FrameDemo{ public static void main(String args[]){ Toolkit toolkit = Toolkit.getDefaultToolkit ();
[Code]...
also if theres any way to shorten up what I have there, that would be great.
I am trying to set the look and feel for my calculator to Nimbus but I am having some problems. It looks horrible though nothing at all like the screenshots I have seen for it.

I am trying to go about making this applet a bit different then normal. The issue I am having is it is drawing an applet but, not the right dimensions, it's able to be resized, lastly the background color is not being set. I mean, I suppose I could call paint() and just draw it out but, I read that I could make the applet pop out to the dimensions I would like. None of this is working sadly.
In NetBeans IDE >> Palette Window >> JFrame properties, I set the background color to (for example) blue but when I run with F6 key, the appearing window is always at gray color. Why?
I've almost finished building an Editor in Java, but i'm a bit stuck on creating a JCheckBox that saves your credentials (as in password only) . I would like it to be on a JPanel under the password input box and above the Login and Register buttons.
Code: Login.java (Main class for this problem)
[URL] ....
The main thing here is using GridLayout, which is what im currently working with but can't seem to get it under the password input box.. check: [URL] ....
I would like to get a checkbox within a table to fire an event when it's clicked rather. I gave tried putting in a TableModelListener but the the event only seems to trigger when I click on another column (as if the table is waiting to see if I will change my mind) before moving on.
I have also looked at the setValue of the TableModel itself.
Do I need to put an ActionListener on each checkbox or have I missed something ?
There are 8 JCheckboxes, which are already added to panel and aligned in group layout. From which, I have selected one JCheckbox. Then the resultant GUI should contain only remaining 7 JCheckboxes and selected one should temporarily removed or hide from GUI . Is it possible? If so, how?
I have moved this to its own thread because I was concerned that I might have hijacked the other OPs thread. As I stated earlier, I decided to try changing the arrowHead on a JComboBox since it should be easy. I created a polygon so I could fill in the shape. However, I believe that the graphics context passed to the paint method has been rotated counter clockwise by 90 degrees. I had assumed that (0,0) would be upper left corner. But (0,0) is lower left corner and (0,height) is lower right corner. Rotate those 90 degrees clockwise and you get them in the (my) expected positions. I also grabbed the AffineTransform from both the paint method and a JPanel paintComponent method. If you examine the trig values for each transformation you will see they are different.
It is not documented in the paint interface. It could just be related to the Nimbus look and feel. I have not checked out others. I did a web search and did not see any info regarding this.
Attached is my modified version of KevinWorkman's code posted in Changing the Foreground Color of ArrowButton of JComboBox in nimbus LaF. I commented out the part that draws the Triangle (It points right instead of down). The key are the circles which should locate the top left and bottom left points.
Is it possible for a rectangle with dotted side be shown when dragging the mouse on a component?Just something like the one in the attachments, usually occurs in some graphics/pictures software.
This is right from a book I'm reading but it doesn't work. The problem is to write an application that lets you determine the integer value returned by the InputEvent method getModifiers() when you click your left, right, or middle mouse button on a JFrame.
This is the code copied directly from the book. What is missing:
import java.awt.event.InputEvent; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import java.awt.event.MouseListener; import javax.swing.JFrame; public class JLeftOrRight {
On a web application i can take a pdf cut it and convert it to html. As a result of this is that i can have my own design(Background) on HTML and then use it on jsp.
Is there a way to do this also in swing ? take a pdf and convert it to jframe or something similar so that i can have my own frame design (Background)?
so i'm supposed to create a jframe with only 1 button. each time you push the button it is supposed to go from red to green to blue to gray and back to red starting over. i can get is the background to change on the first click, then the button is useless for eternity. here is my code:
import java.awt.*; import javax.swing.*; import java.awt.event.*; public class Exercise2_59 extends JFrame implements ActionListener { JButton change;
