Adding a progressbar to a JLayeredPane

Hi,
I am having problems with adding a progressbar to a JlayeredPane.
Below is the code I have.
I can see the JLayeredPane, but cannot see the ProgressBar inside it.
Do u know what the prblem might be ?
ovpg1 is the object for the progressbar and jlp is the object for the JLayeredPane.
Am I missing something ?
Thanks
Amit
JLayeredPane jlp=new JLayeredPane();
JProgressBar ovpg1 = new JProgressBar();
jlp.setPreferredSize(new Dimension(2000,2050));
lp.setBorder(BorderFactory.createTitledBorder("JLayeredPane"));
ovpg1.setStringPainted(true);
ovpg1.setAlignmentX(2.7f);
ovpg1.setBorder(BorderFactory.createTitledBorder(
"The first progressbar's layer and position "));
ovpg1.setValue(90);
ovpg1.setBorderPainted(true);
ovpg1.setBackground(Color.green);
ovpg1.setForeground(Color.red);
jlp.add(ovpg1,new Integer(10)); // Default is the bottom layer.
toolbar.add(jlp);

You also need to realize that a JLayeredPane does not use a LayoutManager to layout your components... You have to manually set the Bounds your self...
try this...
Dimension pref = ovpg1.getPreferredSize();
ovpg1.setBounds(0, 0, pref.width, pref.height);Hope this helps,

Why can't I change the color of my ProgressBar? Always green.

I added a ProgressBar object to my form. Works fine. But the bar is always green despite setting the Forecolor to Blue in the Design and to red in code:
' intTotalNumberOfFiles = 80
pgbCloset.Value = 0
pgbCloset.Step = 1
pgbCloset.Maximum = 99
pgbCloset.ForeColor = Color.Red ' for testing.
For intCnt = 1 To intTotalNumberOfFiles
'If intTotalNumberOfFiles > 0 Then pgbCloset.ForeColor = Color.Green
'If intTotalNumberOfFiles > 30 Then pgbCloset.ForeColor = Color.Yellow
'If intTotalNumberOfFiles > 60 Then pgbCloset.ForeColor = Color.Red
pgbCloset.PerformStep()
Next
Any idea why? How do I fix this? Thx.

... ups, VB,so here's something to start with... (or uncheck the "enable XP visual styles" checkBox in your project's settings)

Progressbar in JTable

Hi
I have added a progressbar to a jtable. but when i add a new record, the earlier record's progressbars are edited. the rows/records are added at random, as the download progresses.
how do i tackle this problem?
Pls help me out. i have only 3 days left to complete my project.

I am not able to understand what u r asking ?
But I think you problem is you are not able to edit all table cell.
I think for JTable u have implemented Renderer and Editor than in Editor's
isCellEditable(java.util.EventObject eventObject)
u need to return true than only you will be able to edit all cells.

Interface update in heavy processing

In heavy processing, interface contents (textbox , progress bar) can not update (being neglected??)
is there any method to force it to get update??
thx for your time in advance.

Interesting enough I just finished adding a progressbar to a script I'm in the works on right now and I got it to work without using update() at all.
I'm using CS5.5, not sure if that's why or not, but what I did for this one was...
var mainRes ="group {orientation:'row', alignment:['fill','fill'], alignChildren:['fill','fill'],\
columnOne: Group{orientation:'column', alignment:['left','top'],\
keyTransPB: Progressbar{minvalue:0, maxvalue:100, alignment:['fill','top']},\
pal.grp = pal.add(mainRes);
In a function way later in the script I have a simple for() loop that also contains...
pal.grp.columnOne.keyTransPB.value++;
and it seems to automatically update the gui without a problem. Maybe try calling your progress bar with it's full path instead of the variable name and see if that works. It might have something to do with functions and variables that declared outside of the function. Not sure if any of that made sense.

Preload Problems

I downloaded some Preloader code from a previous poster. (see
below):
<<<Here is the pre-loader i promised you.
Dont get scared tho, its actually really short. I just added
alot of comments in there to help you understand what is going on
in the code. Plus added a progressBar and Stroke to give some
visuals on loading length.
place this code on Frame 1 of your _root timeline. and make
your movie start from Frame 3. on all layers, make sure there is
Nothing on frames 1 and 2. except the preloading code.

I am fairly new to Flash and I am ussing Flash MX. I have
been trying use it in the first 2 frames of my Flash movie,
however, when I go to test it, I get the following:
l_______________l
Progress.....%
and then nothing happens. It just sits there with no progress
happening. Am I doing something wrong?

Sorry about the confusion. I entered the code as it was. See
the attached link to see how I viewed it in my Flash program. If
you notice, at the top of the window the code:
var loaded:Number =
Math.round(this.getBytesLoaded()/this.getBytesTotal() * 100 );
reads as:
variables: loaded:Number =
Math.round(this.getBytesLoaded()/this.getBytesTotal()*100):

JLayeredPane and added Components

Hi everybody,
I have a panel for drawing, what is actually a JLayeredPane. With the add(someComponent, int layer) I am adding severals JPanel, on which I draw Rectangles for example.
Now I need to change the layer of a certain JPanel in the layeredPane. This is no Problem (with setLayer(...)). But I have one JPanel, its bound by a Rectangle and I added with the add-Method a own Object (it's a line). The line has to be an object, because I added a MouseListener to that line.
It appears like that:
|    (1)    |
|           |
|           |
|-----------|
|           |
|____________It's the line in the middle I'm talking about. So when I change the Layer of the JPanel (the Rectangle), the line has the correct bounds, but is displayed in the upper middle position in the Panel (no. (1) in the graphic).
I tried to remove and re-add it, but nothing helps. Does anybody know the problem?
Thanx for helping!!

By default JLayeredPane uses null layout manager. So you have to set the bound of the component being added into JLayeredPane.

JLayeredPane problem: How to remove object added at specific depth in

JLayeredPane?
For instance, I have a class called BlobEvolution. In that class, I have an array of JLayeredPanes squrares[row][col][depth]. I add an object Blob, to a new LayeredPane cell, using the statement LayeredPane cell=new LayeredPaine();
cell.add(Blob, new Integer(2));, then I add the cell to a contentPane using contentPane.add(cell). I set squares[row][col][0] to point to cell, and squares[row][col][2] refers to the blob object in the cell.
but now I want to remove a certain layer from the cell and repaint that cell to display only the deeper contents of the cell. Or I want to remove the blob in the cell, which is always at depth 2 in the cell. How would I do that? And how do I repaint only that cell?

By the way, both objects that I add to the layeredpanes extend JLayeredPanes.
I actually tried to do this remove call: squares[row][col][0].remove(2);
I was trying to point to the cell layeredpane that contains the two objects, blob, and plankton. blob was placed at depth 2, so I tried to remove the depth 2 component. but I get an ArrayIndexOutofBounds Exception and it says no such child:2. java.awt.Container.getComponent(Container.java:237)
javax.swing.JLayeredPane.remove(JLayeredPane.java:216)
BlobEvolution.removeblob(BlobEvolutioin.java:133)
That's essentially the error message I get in the console. Obviously, it's the remove statement above that's giving me the problem, but I don't know what's wrong with it and how to fix it.
Please, if anyone can help I'd really appreciate it.

JLabel Image Icon lost after added to JLayeredPane

This is probably that is relatively trivial:
I have a created a simple class that extends a JPanel
Within the JPanel I add a JLayeredPane
Within the JLayeredPane I add two JLabels
The two JLabels are image placeholders (set using the *.setIcon method)
Images are set in the JLabels using a public method setImage (for each label respectively)
In the super class that invokes this, the object (myPanel) with the JPanel shows the panel fine along with the JLayeredPane, anyways this is the problem say "myPanel" calls the method setImage (myPanel.setImage...), the image is set in the JLabel componenent in the JLayeredPane but it seems to get erased when a windows goes over!
What am I doing wrong?
Thank you for your time.

Help adding to JLayeredPane

basically I need to create a panel with a background, then use JLayeredPane to put 2 other panel on top of each other over the background. The problem is that each panel will display properly by with the background but not all 3 together.

How can i use Progressbar for loading data to DataGridView using DataTable

I have a datatable which have 3 columns and set this datatable to be datasouce of datagridview.
I want to add 100000 rows into this table while
table is adding , I want Progressbar to calculate and show the remaining
percentage.
How can i do this ?

I've seen this done 2 different ways.
You could either set the ProgressBar.Maximum to: 100, or to QuantityToLoad.
example:
Option Strict On
Option Explicit On
Option Infer Off
Public Class Form1
Dim QuantityToLoad As Integer = 100000
Dim increment As Double = 100 / QuantityToLoad
Private Sub btnExample1_Click(sender As Object, e As EventArgs) Handles btnExample1.Click
ProgressBar1.Value = 0
ProgressBar1.Maximum = 100
ProgressBar2.Value = 0
ProgressBar2.Maximum = QuantityToLoad
For i As Integer = 1 To QuantityToLoad
'Some code
'Some code
'Some code
'Done loading item
ProgressBar1.Value = CInt(i * increment)
ProgressBar2.Increment(1)
Label1.Text = ProgressBar1.Value.ToString & "% complete."
Label2.Text = CStr(Math.Round((ProgressBar2.Value / ProgressBar2.Maximum) * 100, 2)) & "% complete."
Application.DoEvents()
Next
MsgBox("done")
End Sub
End Class

How to use JLayeredPane with LayoutManager

Hi!
I'm having problems with JLayeredPane. I simply cannot understand how to use it. I would like to have a button on top of my JDialog (The Dialog should have two components, a custom drawing panel and a JButton to close it with (want to keep the window undecorated, thus the need for the close-button)).
AboutDialog
|******Animation here***<- ------- CustomPanel
|**************************|
| *********and here*******|
| ******** ______*********|
| &here | Close | &here |<-----JDialog
| ******** ----------*********|
+------------------^---------- --+
...........................|
..........................JButton
This is what i tried, after finding out that JLayeredPane has a null layout:
class FilledLayeredPane extends JLayeredPane {
public FilledLayeredPane() {
     super();
     addComponentListener(new ComponentAdapter() {
          public void componentResized(ComponentEvent e) {
          compRes();
//Resize all components to fit
protected void compRes() {
     Component[] comps = getComponents();
     Rectangle bounds = getBounds();
     for (int i=0; i<comps.length;i++)
     ((JComponent) comps).setBounds(bounds);
Then i added two panels with different z-order. One panel with the button, and also the CustomPanel.
However, the resize algorithm is ugly, and it doesn't work as it should at all. I'm getting really random behaviour from this...
How am i supposed to do?? I want the LayeredPane to layout the components i add to it! At least make sure that all added component fill up the size of the LayeredPane...
Plz help!

Forgive me, that was bs. I get correct componentResized notificatiuons every single time.
The problem is: My manual updates of the JPanel inside the JLayeredPanel DO work, and the JPanel is resized correctly (otherwise I would see elements from behind shinig through).
BUT the JPanel doesn't always take the fact that it is manually resized as a reason to layout its components!!!
In my case, it works, as far as I've seen, EXACTLY EVERY SECOND TIME!!!
The solution is indeed VERY simple: After manually resizing an element with a layout that is non-null, call layout() on that element!!!
In my case,
jpanelXXX.setSize(size); jpanelXXX.layout();works wonders!!!

JTable in JLayeredPane - resize table header cursor

Hey everybody, I have searched all over this forum and the net for an answer to this problem. I have a class that adds a JComponent to a JLayeredPane in the default layer. In another layer above the default layer is a JComponent that exists only to provide a 'pretty' image border with round corners that overlap the component below it. It works and looks very good. The only problem I have found is that if the JComponent that is added (in the default layer) is a JTable the cursor no longer changes to the resize cursor (<->) when mousing over the table header column edges. I can still resize the columns but I need to have the cursor change to indicate that the colums can be resized for user friendliness. I assume that the mouse events are getting trapped by the upper layer in the JLayeredPane and aren't reaching the JTable in the lower layer as they need to.
I have tried swapping the two layers but when I do that the corners of the component that I want to add the border to overlap over the nice round corners of the border which defeats the purpose.
If anyone has any suggestions, or even better a solution, that would be great!
Thanks,
Erik

table.getTableHeader().setVisible(false); will
help.This is necessary, but probably not quite sufficient for picky users. You may also want to set the min, max, and preferred dimensions of the table header to 0,0, otherwise you get what looks like a top-only border.

JLayeredPane - keeping all contained components filling the layeredPane

I'm having some troubles keeping contained components inside a JLayeredPane so they're all filling the pane.
The desired effect I want is to have a region of the window that contains two panels -- one for standard view/editing, and an overlayed transparent panel above it, which, at times, will show icons overlayed over the base panel -- basically an OSD layer over a panel that will be showing video.
I've gone the approach of using a JLayeredPane and adding the base panel, but I'm having troubles getting it to make sure it fills the entirety of the JLayeredPane.
I thought of several approaches:
1.) Set up the JLayeredPane with a BorderLayout, and set the components all to CENTER, but then I realized that with BorderLayout, each position can only have one component assigned to it.
So, this approach is a no-go. :(
2.) Set up a ComponentListener on the JLayeredPane, listening for componentResized, and resizing the contained panels to event.getComponent().getSize(). This approach did result in a resize happening on the component I was testing, but alas, it resizes it to the original, pre-resized size! Reading the docs, and what others have said on the msg board, this seems to be going against what I'm reading and hearing about.
Does anyone have any ideas for me? I'm all ears.
Is there a radically different approach I could take?
What I'm going after is kinda like the glassPane feature on a Frame, but I'm not working with a frame, just one panel inside the frame of my main application window.. And I'd like it so I could encapsulate the OSD panel in it's own derived class -- that's what I'm doing right now -- so I can have custom methods for manipulating the OSD.

For this type of situation, I usually subclass JLayeredPane and override the doLayout() method. In there, assuming you want to have everything on it's layer fill the layer it's on, just set it's bounds to (0, 0, w, h) with the width/height of the layered pane itself. Aha! That worked like a charm! Just what I was after. I need to get more comfortable altering the inner-workings of swing components through subclassing.
If you need something more advanced, you'd have to have a way to determine which components should go where/what size.Nope -- I didn't need to subclass in this case -- I want each and every item in the JLayeredPane to fill the entirety of the container. I sorta figured that there should be a relatively easy solution to it, but I hadn't been able to figure out how, and googling it up didn't seem to result in any useful information on the subject.
Thank you very much bsamieri!
Here's exactly what I ended up doing:
package com.tripleplayint.newvideopreviewermockup;
import java.awt.Component;
import javax.swing.JLayeredPane;
* A panel widget that allows components to be layered on top of one another,
* where each component fills the entirety of this container.
* This is only useful when all but the lowest layer is set transparent, as
* the highest opaque layer will obscure any layers below it.
* @NOTE If one wants to move the layers to choose which one is visible, your
* better option is to use a JPanel with the CardLayout.
* @author kkyzivat
public class FilledLayeredPane extends JLayeredPane {
     * Layout each of the components in this JLayeredPane so that they all fill
     * the entire extents of the layered pane -- from (0,0) to (getWidth(), getHeight())
    @Override
    public void doLayout() {
        // Synchronizing on getTreeLock, because I see other layouts doing that.
        // see BorderLayout::layoutContainer(Container)
        synchronized(getTreeLock()) {
            int w = getWidth();
            int h = getHeight();
            for(Component c : getComponents()) {
                c.setBounds(0, 0, w, h);
}

Resizing Components in a JLayeredPane

Hello,
I'm brand new to Java (formerly a VB man). I'm creating an application where icons are displayed on a background image and can be dragged around the window. The background image and the icons need to resize with the window.
I've managed to get the back ground image to resize but can't work out how to get the icon images to resize as well. I also need to keep their relative positions as well.
I have three classes which extend JFrame, JLayeredPane and JPanel to construct the display. I have attached them below.
If anyone can help or at least point me in the right direction I would be very grateful indeed.
Best regards
Simon

Try useing the JFrames show() method or setVisible(true) method after you have added all the other components.
If that doesnt work use the JFrames validate() method, inherited from Container, after one of the previous methods.
Hope this helps
