Have Problems Implementing Grid View

[AnteeN]

Hello all i have a problem implementing a code into my code.

I need some guidance where i am doing it wrong?

The code i am trying to implement is;

setLayout(new GridLayout(2, 2));
ScrollingImagePanel panel = new ScrollingImagePanel(image1, width, height);
add(new ScrollingImagePanel(im1, width, height));
add(new ScrollingImagePanel(im2, width, height));
add(new ScrollingImagePanel(im3, width, height));
add(new ScrollingImagePanel(im4, width, height));
pack();
show();

The code that i am trying to implement in is;

Interpolation interp = Interpolation.getInstance(Interpolation.INTERP_BIL INEAR);
ParameterBlock params = new ParameterBlock();
//System.out.println(ImPath[i]);
RenderedImage image = (RenderedImage)JAI.create("fileload",ImPath[i]);
params.addSource(image);
params.add(0.5F); // x scale factor
params.add(0.5F); // y scale factor
params.add(0.0F); // x translate
params.add(0.0F); // y translate
params.add(interp); // interpolation method
RenderedOp image1 = JAI.create("scale", params);
int width = image1.getWidth();
int height = image1.getHeight();
Frame window = new Frame("Scrolling Image Panel Example");
window.add(panel);
window.pack();
window.show();

I need to show the images in a grid view.

Does anyone has a clue?

Kind Regards

RenderedImage image = (RenderedImage)JAI.create("fileload",ImPath[i]);
params.addSource(image);
params.add(0.5F); // x scale factor
params.add(0.5F); // y scale factor
params.add(0.0F); // x translate
params.add(0.0F); // y translate
params.add(interp); // interpolation method
RenderedOp image1 = JAI.create("scale", params);
int width = image1.getWidth();
int height = image1.getHeight();
ScrollingImagePanel panel = new ScrollingImagePanel(image1, width, height);
int ImCount = list.getItemCount();
int DGridW = 0;
int DGridH = 0;

if ((ImCount % 2) == 0)
{
DGridW = ImCount / 2; //Display Grid Assignment Width
DGridH = ImCount / 2; //Display Grid Assignment Height
}
else
{
int ImCountEven = (ImCount+1);
DGridW = ImCountEven / 2; //Display Grid Assignment Width
DGridH = ImCountEven / 2; //Display Grid Assignment Height
}
panel.setLayout(new GridLayout(DGridW,DGridH));
panel.add(new ScrollingImagePanel(image1, width, height));
Frame window = new Frame(" " + ImPath[i]);
//window.add(panel);
window.pack();
window.show();

This is what i can do so far but i get the exception of;

Exception in thread "AWT-EventQueue-0" java.awt.AWTError: ScrollPane controls layout
at java.awt.ScrollPane.setLayout(Unknown Source)
at CamCalib$3.actionPerformed(CamCalib.java:143)

143 = panel.setLayout(new GridLayout(DGridW,DGridH));

Any clues?

What is the definition of the ScrollingImagePanel class?

[AnteeN]

Thank you for the reply.

Definition;

Note: This element neither has attached source nor attached Javadoc and hence no Javadoc could be found.

thanks.

If you can't say how the ScrollingImagePanel class is defined, then not much can be done

hmmm...

I have searched the web..

setLayout

public final void setLayout(LayoutManager mgr)
Sets the layout manager for this container. This method is overridden to prevent the layout mgr from being set.
Overrides:
setLayout in class Container
Parameters:
mgr - the specified layout manager

information came out but as i am a Newbie... I can not understand what it means.

Presuming (from the error message) ScrollingImagePanel extends JScrollPane then, from the API for setLayout:
"
This method overrides setLayout in java.awt.Container to ensure that only LayoutManagers which are subclasses of ScrollPaneLayout can be used in a JScrollPane.
"
