Thread: revalidating JPanel when image is deleted from file

When the user presses the delete button, the code below runs but, I cannot figure out why, the images I have deleted from the file directory won't update on pPanel. this panel consist of a JSplitPane which consists of a JScrollPane and bPanel (for the buttons) and the JScrollPane has a JList which has a DefaultModelList.

 class dListener implements ActionListener {
			public void actionPerformed(ActionEvent event) {
				//System.out.println("delete");
 
				if(listofFiles.length < 0)
				{
					return;
				}
 
				if(event.getSource() == dButton)
				{
					File folder = new File(path);
					File[] listofFiles = folder.listFiles();
 
					int a = list.getSelectedIndex();
 
					try {
						listofFiles[a].delete();
						System.out.println(listofFiles[a].getName() + " is deleted");
 
						//bPanel = buttonPanel(bPanel);
						//listModel = loadImages();
						//list = new JList(listModel);
						//photoLister = new JScrollPane(list);
						//imageSplit = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, photoLister, bPanel);
 
						pPanel.revalidate();
						pPanel.repaint();
 
					} catch (Exception x) {
 
						x.printStackTrace();
					}
				}
 
			}
	 }

Have you tried reprinting the whole frame?

what I mean by "update on pPanel" is that once I have removed an image path from my file system, I want it to show on the panel that it has been deleted/removed

--- Update ---

I have, in my main class I did f.revalidate(); and f.repaint();

its still not updating.

I tried creating a new DefaultModelList, JList, JScrollPane, and JSplitPane. but when I do that, the pictures update & the bPanel disappears (panel with buttons) [bPanel is created with a seperate function]

I want it shown on pPanel, which consists of the jsplitpane that has the jscrollpane and the button panel

& I don't' have a component that shows whether the image is sucessfully loaded or can't find image yet, as of right now I'm just printing it in the command line

I can display a JLabel in the bPanel, and it can show the user whether they uploaded the image sucessfully. but my original problem was to show that the image in the jscrollpane has been deleted once the user deletes the image from the file system
