RCP Editor 常見錯(cuò)誤處理方法
1."org.eclipse.ui.PartInitException: Unable to open editor, unknown editor ID: package.class"處理方法
報(bào)錯(cuò)原因：plugin.xml中<extension>標(biāo)簽中沒有icon項(xiàng)
<extension
point="org.eclipse.ui.editors">
<editor
class="testrcp.testeditor"
id="testrcp.testeditor"
name="New EditorPart">
</editor>
</extension>
解決方法：plugin.xml中<extension>加入icon，該項(xiàng)可以為空。
<extension
point="org.eclipse.ui.editors">
<editor
class="testrcp.testeditor"
icon=""
id="testrcp.testeditor"
name="New EditorPart">
</editor>
</extension>
2."org.eclipse.ui.PartInitException: Editor initialization failed: package.class. Site is incorrect."處理方法
報(bào)錯(cuò)原因：EditorPart類的init()未實(shí)現(xiàn)
package testrcp;
import org.eclipse.core.runtime.IProgressMonitor;
import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.ui.IEditorInput;
import org.eclipse.ui.IEditorSite;
import org.eclipse.ui.PartInitException;
import org.eclipse.ui.part.EditorPart;
public class testeditor extends EditorPart {
public static final String ID = "testrcp.testeditor"; //$NON-NLS-1$
/**
* Create contents of the editor part
* @param parent
*/
//@Override
public void createPartControl(Composite parent) {
Composite container = new Composite(parent, SWT.NONE);
//
}
@Override
public void setFocus() {
// Set the focus
}
@Override
public void doSave(IProgressMonitor monitor) {
// Do the Save operation
}
@Override
public void doSaveAs() {
// Do the Save As operation
}
@Override
public void init(IEditorSite site, IEditorInput input)
throws PartInitException {
}
@Override
public boolean isDirty() {
return false;
}
@Override
public boolean isSaveAsAllowed() {
return false;
}
}
解決方法：實(shí)現(xiàn)init()方法如下
public void init(IEditorSite site, IEditorInput input)
throws PartInitException {
System.out.println(input.toString());
this.setInput(input);
this.setSite(site);
}
3."org.eclipse.core.runtime.AssertionFailedException: null argument:A part's title tool tip must be non-null"處理方法
報(bào)錯(cuò)原因：EditorInput類的getToolTipText()返回值為null
package testrcp;
import org.eclipse.core.runtime.IPath;
import org.eclipse.jface.resource.ImageDescriptor;
import org.eclipse.ui.IPathEditorInput;
import org.eclipse.ui.IPersistableElement;
public class testEditorInput implements IPathEditorInput {
public testEditorInput() {
// TODO Auto-generated constructor stub
super();
}
@Override
public IPath getPath() {
// TODO Auto-generated method stub
return null;
}
@Override
public boolean exists() {
// TODO Auto-generated method stub
return false;
}
@Override
public ImageDescriptor getImageDescriptor() {
// TODO Auto-generated method stub
return null;//WorkbenchImages.getImageDescriptor("");
}
@Override
public String getName() {
// TODO Auto-generated method stub
return "testEditorInput";
}
@Override
public IPersistableElement getPersistable() {
// TODO Auto-generated method stub
return null;
}
@Override
public String getToolTipText() {
// TODO Auto-generated method stub
return null;
}
@Override
public Object getAdapter(Class adapter) {
// TODO Auto-generated method stub
return null;
}
}
解決方法：重寫getToolTipText()方法return值可以為""或任意字符類型。
public String getToolTipText() {
// TODO Auto-generated method stub
return "";
