.eclipseswtchartsettings to .eclipse/org.eclipse.swtchart.extensions/settings/chart.properties

[Mailaender]

Currently, to resolve flathub/com.lablicate.OpenChrom#9 I need to allow writing the whole $HOME folder, which will likely be rejected by the administrators as default permission or flagged as a security problem in the app store. This reuses the existing .eclipse folder to make it easier to locate and avoids the concatenation, which is pretty unreadable and unusual in the English language.

This leads to a FileNotFoundException:

I also recommend to IDN of the package org.eclipse.swtchart.extensions as a folder name in .eclipse to follow the style of all other folders contained. Additionally, I would recommend to rename settings to chart.properties.

[eselmeister]

	public static IPreferenceStore getPreferenceStore() {

		if(preferenceStore == null) {
			/*
			 * SWTChart may be used also in a non Eclipse context.
			 * Hence, a simple file preference store instead of a ScopedPreferenceStore is used.
			 */
			StringBuilder builder = new StringBuilder();
			builder.append(System.getProperty("user.home"));
			builder.append(File.separator);
			builder.append(".eclipse");
			builder.append(File.separator);
			builder.append("org.eclipse.swtchart.extensions");
			/*
			 * Create the directory if necessary.
			 */
			File directory = new File(builder.toString());
			if(!directory.exists()) {
				directory.mkdirs();
			}
			/*
			 * Specify the settings file.
			 */
			builder.append(File.separator);
			builder.append("chart.properties");
			File file = new File(builder.toString());
			try {
				if(!file.exists()) {
					file.createNewFile();
				}
			} catch(IOException e) {
				// Ignore
			}
			/*
			 * Create the preference store
			 */
			if(file.exists()) {
				preferenceStore = new PreferenceStore(file.getAbsolutePath());
			} else {
				preferenceStore = new PreferenceStore();
			}
			//
			PreferenceInitializer preferenceInitializer = new PreferenceInitializer();
			preferenceInitializer.initializeDefaultPreferences();
			/*
			 * Load existing values.
			 */
			try {
				((PreferenceStore)preferenceStore).load();
			} catch(FileNotFoundException e) {
				// Ignore
			} catch(IOException e) {
				e.printStackTrace();
			}
		}
		//
		return preferenceStore;
	}

[Mailaender]

I created a less verbose version that also fixes #380 because you are calling

swtchart/org.eclipse.swtchart.extensions/src/org/eclipse/swtchart/extensions/preferences/PreferenceInitializer.java

Line 24 in 7723313

IPreferenceStore preferenceStore = ResourceSupport.getPreferenceStore();

which then calls itself again, which causes the exception to be so spammy.

[eselmeister]

Still a FileNotFoundException is thrown by running your code. It only works if the file is already available, which can't be assumed:
