Repaint() doesn't clear the frame
(3 answers)
Closed 3 years ago.
My paint code won't stop overwriting the previous graphics I draw. Whenever I drag my mouse, it's supposed to create a dot and leave it there as it draws a new one in a new location. That doesn't seem to be happening here because when paint() is called, it clears the previous dots. I'll be posting the full code first then the paint() section and then the Mouse Dragged listener. I'm using NetBeans IDE with its prebuilt JForm

2) Relevant to painting:
#Override
public void paint(Graphics g)
{
penSize = jSlider1.getValue();
penState = jToggleButton1.isSelected();
eraseState = jToggleButton2.isSelected();
setBackground(bgColor);
g.setColor(penColor);
this.paintComponent(g);
if(touchState){
g.fillOval(mousePoint.x, mousePoint.y, penSize, penSize);
}
}
3) Mouse Dragged Event
private void jPanel2MouseDragged(java.awt.event.MouseEvent evt) {
touchState = true;
mousePoint = evt.getPoint();
System.out.println(mousePoint);
repaint();
}
I would prefer to not have to use a data structure to store the value of every point and then repaint.
You're not calling the super's painting method within your paint method override, and this prevents component housekeeping painting from being done, including removal of "dirty" pixels. Suggestions:
Override a JPanel's paintComponent method, not its paint method
Call the related super's painting method as the first line of your override. So if you're overriding paintComponent(Graphics g), call super.paintComponent(g) on the first line.
If you need to draw multiple dots, then either draw them to a BufferedImage or create an ArrayList<Point> and place your points into the array list and iterate through them.

What I'm doing is calling the toggleMenu() method from my Main class(named Overlay) upon a key press, and it flips the isVisible boolean. Thing is, when I press the button, it doesnt do anything. Then when I press it again, it creates a new Window with a different look and feel(not the one i specified initially).
I also tried to use the hide(); and show(); methods, but without success.
So what am I doing wrong? I am not really familiar with how Netbeans handles gui creation, although i think this should work.
Fixed, in the run method, change this:
public void run() {
new Menu().setVisible(true);
}
to this:
public void run() {
m = new Menu();
m.setVisible(true);
}
(Create a static Menu object called m, and then in the toggleMenu() method, use
m.setVisible(true);
or false. Closed.
i'm currently working on a java desktop project , oddly enough whenever i hit the run button , the Jpanel doesn't show up. I declared this as main but still it doesn't works. Any ideas ?
Here is the code for my Jpanel form.
Thanks in advance!.

Nothing "odd" about this. Your ventana class is a JPanel, and yes, you create it and set it visible, but a JPanel by itself can not display, and to in fact have it show, it needs to be part of a visible "top-level window" such as a JFrame or JDialog. So if you want to show this JPanel in its own separate dialog window, put it into a JDialog, pack() the dialog, and then set the dialog visible. Or the quick and dirty way to do this is to put the ventana JPanel into a JOptionPane. e.g.,
JOptionPane.showMessageDialog(null, new ventana());
A JOptionPane will then create and display a modal JDialog that will display your ventana object.
Note that the ventana class name should begin with an upper-case letter, like all Java class names should.
In my application I have 3 classes that extends JInternalframe. One is MainFrame. Suppose Mainframe has four JTextFields. TF1, TF2, TF3, TF4. When the MainFrame is opened TF1 got focus by default.
Now user will press enter and go to TF2. In the next step depending on a condition Another JInternalFrame SubFrame_1 or SubFrame_2 will get opened as a floating window.
SubFrame_1 has four different TextFields. TF5, TF6, TF7, TF8. Again TF5 got focus by default. Some calculations will be done here and when user presses enter in TF8 SubFrame_1 will be disposed. And the MainFrame should regain focus in TF3. The same condition may be applied to SubFrame_2. But when SubFrame_1 is disposed TF3 never gain focus. More horrible thing is that sometimes the MainFrame does not get focused when the SubFrame is disposed. How can I get rid of this issue? I've tried all sort of function requestFocusInWindow(), requestFocus(), grabFocus() etc. Please help.
Here is my small example:
public class Form1 extends javax.swing.JFrame {
/**

I've been trying to add an array of JCheckBoxes to a JPanel in Netbeans that has been automatically generated by the Netbeans GUI, when I create an array of the JCheckBoxes and then try to add them to the JPanel using JPanel.add(jCheckboxArray[x]) , the program compiles ok but they don't appear.
I've created an array like so:
// custom private member variables
private javax.swing.JCheckBox[] jCheckboxArray;
//
int CheckBoxNumber = 5;
jCheckboxArray = new javax.swing.JCheckBox[CheckBoxNumber];
for(int x = 0; x < CheckBoxNumber ; x++) {
jCheckboxArray[x] = new javax.swing.JCheckBox();
jCheckboxArray[x].setText("CheckBox " + x);
}
I've tried setting viable but no result, and all the examples online appear to make a reference to adding the JPanel to a JFrame however no JFrame exists in the auto-generated code probably because the auto generated class extends javax.swing.JFrame.
Any help greatly appreciated.
Here is the entire code:

I am developing an application using Java, Swing. It will be mainly used in order to study oscillograms against pentagrams for medical purposes. It is wished that the user can keep notes on top of the images (presumably something like the pencil used in Window's paint).
Please, keep in mind that every time the user loads an image, the following mouse motion listener gets attached to it (in order to make the image draggable for usability reasons):
public class DragMouseListener implements MouseMotionListener {
JLabel jl;
int imageX, imageY;
public DragMouseListener(JLabel jlabel) {
this.jl = jlabel;
jl.addMouseMotionListener(this);
}
#Override
public void mouseDragged(MouseEvent e) {
updateImagePosition(e);
}
#Override
public void mouseMoved(MouseEvent e) {
}
private void updateImagePosition(MouseEvent e) {
imageX = e.getX();
imageY = e.getY();
jl.setLocation(imageX, imageY);
}
}
Until now I am unable to even come close to a way of implementing it and I cannot find any references of the issue in the Internet. Any help (even rough ideas) would be much appreciated. Thanks in advance.
Nick
I tried what you asked for DragMouseListener but found it very uncomfortable so used JInternal Frame it works fine(but you can still drag images inside JInternal Frame,as I implemented what you asked for).Insted of hand free writing,I used JEditorPane(you can add hand written thing if you want,but it will be a mess) with accessible parent JScrollPane so that you can type how much you want.
You can drag JInternal Frame easily:
Note: I have used NetBeans GUI Builder for this and suggest you too to use any GUI builder as it makes
typing work easy.
